Port 1 provides the multiplexed address inputs. The address information at port 1 is latched with the signal PALE. For basic programming mode selection the inputs RST, PSEN, PROG, PRD, PALE, PSEL, and EA/VPPx are used. EA/VPPpixel is used for programming the character ROM, EA/VPPprogr is used for programming the program ROM. Further, the inputs PMSEL1,PMSEL 0 are required to select the access types (e.g. program/verify data, write lock bits, ....) in the programming mode as they are defined in table 2. During OTP programming mode VDD, VSS, VDDA, VSSA, IREF, XTAL1 and XTAL2 must be applied to the SDA 545XOTP. The 11.5V external programming voltages are input through the EA/VPPx pin.

Programming Mode Selection

The selection for the OTP programming mode can be separated into two different parts : ­ Basic programming mode selection ­ Access mode selection With the basic programming mode selection the device is put into the mode in which it is possible to access the OTP through the programming interface logic. Further, after selection of the basic programming mode, each OTP access is executed by using one of the access modes. These access modes allow OTP byte program/verify, test mode register read/write operations, and programming lock byte access. 3.1 Basic Code Programming Mode Selection

With a falling edge of PSEL the logic state of PROG and EA/VPPprogr is internally latched. The selected OTP Model remains active until PSEL is raised again. These two signals are now used as

programming write pulse signal (PROG) and as programming voltage input pin VPP. When EA/ VPPprogr is raised to VIH1 or VPP level, the access modes according table 2 can be activated. 3.1.1 Access Mode Selection Table 2 defines the access modes which are available in the code programming mode.

The access modes from the table above are basically selected by the two PMSEL1,0 lines. The PROG and PRD signal are the write and read strobe signals. Data is transfered at port 0 and addresses are applied to port 1. Depending on the selected access mode, addresses must be latched at port 1. 3.1.2 Program and Verify Code Bytes The program/verify code byte access mode is defined by PMSEL1,0 = '1','1'. It is initiated when the PMSEL1,0 = '1','1' is valid at the rising edge of PALE. In the program/verify code byte access mode a so called Page Mode timing is specified. In the Page Mode timing only the lower address byte must be latched at port 1. This is the standard timing which is used for programming and verifying the code bytes of the OTP memory. If subsequent OTP address locations are accessed with constant address information at the high address lines A8-15, A8-A15 must only be latched once per page at port 1 (page address mechanism). 3.1.2.1 Program Code Bytes

The following steps must be executed for programming of a code byte: 1. Program access mode has to be selected by setting PMSEL1,0 to '1', '1' and A8-A15 must be set. PALE must be activated (high pulse). PMSEL1,0 must fulfill a setup time to the rising edge of PALE and A8-A15 must satisfy a setup and hold time to the falling edge of PALE. 2. Addresses A0-A7 must be statically applied to port 1. 3. The code/character byte to be programmed must be applied to port 0. 4. EA/VPPprogr must be set to VPP (if it was not at VPP before), EA/VPPpixel is set to '1' 5. PROG is pulsed to low level for the OTP code byte programming. For multiple code byte programming, steps 2 to 5 are repeated. If the address lines A8-A15 must be updated, PALE must be activated for the latching of the new A8-A15 value (step 1). The programming voltage at EA/VPPprogr can be stable at VPP during multiple byte programming. Control, address, and data information as well as the programming voltage VPP must only be switched when the PROG and PRD signals are at high level. Step 1 must be always executed if a different access mode has been executed prior to the actual programming cycle or if the value of the high address A8-A15 is different to the high address of the last programming/verify mode access. Pin EA/VPPprogr must be raised from VIH1 to VPP at least before PROG becomes active for the first time.

With a falling edge of PSEL the logic state of PROG and EA/VPPpixel is internally latched. These two signals are now used as programming write pulse signal (PROG) and as programming voltage input pin VPP. When EA/VPPpixel is raised to VIH1 or VPP level, the access modes according table 2 can be activated.The selected OTP Model stay selected until PSEL is raised again. 3.2.1 Access Mode Selection Table 2 defines the access modes which are available in the character programming mode.

Depending on the selected access mode, addresses must be latched at port 1. 3.2.2 Program and Verify Character Bytes The program/verify character byte access mode is defined by PMSEL1,0 = '1', '1'. It is initiated when the PMSEL0 = '1', '1' is valid at the rising edge of PALE. Only the lower address byte must be latched at port 1. This is the timing which is used for programming and verifying the code bytes of the OTP memory. If subsequent OTP address locations are accessed with constant address information at the high address lines A8-15, A8-A15 must only be latched once per page at port 1 (page address mechanism).

3.2.2.1

Program Character Bytes

Since each line of one character consists of 12 bits, it is split into two bytes and as such has two addresses. The first character byte (having an even address) contains the first 8 bits of the character line, the second character byte (having an odd address) contains the remaining four bits at its four LSBs. The four MSBs must be '0'. Due to that, it is strongly recommended to first program all character bytes and to perform the verification afterwards. To reduce programming time, every second programming pulse width (at even address) can be reduced to 1µs instead of tPWW. Figure 9 shows a typical Page Mode basic programming cycle of one OTP character byte.

been executed prior to the actual programming cycle or if the value of the high address A8-A15 is different to the high address of the last programming/verify mode access. Note: It is strongly recommended to first program all character bytes and to perform the verification afterwards, because each character line is written in two steps as described in 3.2.2.1. 3.2.3 Access of Lock Bits The SDA 545XOTP has two programmable lock bits which, when programmed according table 4 or table 5, protect the on-chip memory. Erasing the EPROM also erases the program lock bits, returning the OTP device to full functionality. Obviously, the erasing of the lock bits is no more possible when the OTP device is mounted in a plastic package. The state of the lock bits can also be read. Table 4 : Lock Bit Protection Types for Program ROM Lock Bits at D1,D0 D1 1 0 D0 1 0 Protection Protection Type Level Level 0 Level 3 No OTP lock feature enabled. OTP programming and verification is disabled.

Table 5 : Lock Bit Protection Types for Character ROM Lock Bits at D1,D0 D1 1 0 D0 1 0 Protection Protection Type Level Level 0 Level 3 No OTP lock feature enabled. OTP programming and verification is disabled.

Note : '1' means that the lock bit is unprogrammed. '0' means that lock bit is programmed. Figure 11 and figure 12 show the waveform of a lock bit write/read access. When a protection level has been activated by programming of the lock bits, the basic programming mode must be left for activation of the protection mechanisms. This means, after the activation of a protection level further OTP program/verify operations are still possible if the basic programming mode is maintained.

Since the organization of pixel data inside the ROM differs from former TVText-versions (SDA 525x), it is explained in this chapter. A further explanation is necessary due to the splitting of the 12 pixel per character-line into two 8-bit write cycles. 4.1 Basics of the ROM Organization

The character ROM consists of 4096 words of 12 bit each. Since each character has 10 lines, a maximum of 409 characters can be stored. There are six basic blocks of character data: 1.) the OSD64 character set, 2.) the G0 character set, 3.) the OSD character set, 4.) the Extended West character set, 5.) the Turkish character set, and 6.) the Extended East character set. The mosaic graphics character set is generated by hardware and, due to this, not included in the character ROM. The data format used is the same as in the former TVT-circuits (SDA 525x) based on ASCII (consisting of 0 and 1). To use this data for the OTP version, the order of data has to be changed, due to the linear addressing of the OTP-ROM and the character organization. In the first step, the character sets must be reordered, in the second step the 12b-words must be handled in a special way. 4.2 Order of the character sets inside the address space

The first step is a reordering of pixel data according to the following specification: 4.2.1 Order of the character sets in former ASCII-files (SDA525x) Address 000-01F 020-07F 080-09F 0A0-0FF 100-11F 120-13F 140-15F 160-17F 180-19F 1A0-1FF Character Set empty G0 OSD Extended West empty Mosaic Graphic 1 OSD64 Mosaic Graphic 2 Turkish Extended East

4.2.2 New Order of the character sets in ASCII-file (SDA545x) Address 000-01F 020-07F 080-09F 0A0-0FF 100-11F 120-17F Character Set OSD64 G0 (as before) OSD Extended West (as before) Turkish Extended East

The mosaic graphic character sets are generated by hardware and, by this, are not included neither in the ROM nor in the pixel data file. 4.3 Organization of Words inside the Address Space

After reordering of the character sets the pixel lines must be ordered. This is necessary because each character has 10 lines. In the former TVT-Versions each character line was addressed by ,,character-address . line-number". The address mapping was performed by hardware. In the OTPversion the line addresses must be scrambled before programming to exploit the full linear address space. This scrambling must be done as described in the following:

CA: Character address (9 bit); LA: line address (4 bit); C-symbols are used (||: or; !: not) Case 1: Valid for character adresses 0dec to 255dec (000000000b to 011111111b; 000h to 0FFh): Character Line Address = LA3; LA2; LA1; LA0; CA7; CA6; CA5; CA4; CA3; CA2; CA1; CA0 Case 2: Valid for character adresses 256dec to 383dec (100000000b to 101111111b; 100h to 17Fh): Character Line Address = 1; LA3 || LA2; !LA2; LA1; LA0; CA6; CA5; CA4; CA3; CA2; CA1; CA0 4.4 Order of MSB and LSB

The MSB represents the leftmost pixel, the LSB represents the rightmost pixel.
