MCS-80TM USER'S MANUAL
(WITH INTRODUCTION TO MCS-85TM)
The MCS-80TM family of microcomputer components has been greatly
expanded since the last version of the MCS-80 manual was published in
September, 1975. Over the last two years, expansion of MCS-80 family
devices, coupled with the best system development support in the industry,
have made Intel's 8080A the industry standard microprocessor.
Now Intel introduces the MCS-85 family, an evolutionary system based
around the third generation 8085 microprocessor. MCS-85 has all the features
of an MCS-80 system with higher performance and lower cost. MCS-85, the
next industry standard for new designs.
Over forty microcomputer components are described in detail in this manual.
Among the newest are:
8251A Improved Programmable Communication Interface
8253 Programmable Interval Timer
8255A Improved Programmable Peripheral Interface
8257 Programmable DMA Controller
8259 Programmable Interrupt Controller
8279 Programmable Keyboard/Display Controller
2716 2K x 8 EPROM, 5 Volt Only
2114 1K x 4 Static RAM
2116 16K x 1 Dynamic RAM
8085 5 Volt Advanced 8080 Processor
8155/56 Combination 256x8 Static RAM, 22 I/O Lines, 14-bit Counter
8355 Combination 2K x 8 ROM, 16 I/O Lines
8755 Combination 2K x 8 EPROM (5 Volt), 16 I/O Lines
