CM7000 14 s Overview
Introduction
The CM7000 is a microprocessor core module. The CM7000 combines a
complete system engine with integrated development software. You build
your own controller around the plug-in CM7000.
Features
• Small size: 1.80" × 2.05" (45.7 mm × 52.1 mm)
• Microprocessor: Z180 running at 9.216 MHz or 18.432 MHz, includ-
ing two DMA channels, two serial ports, and two programmable timers
(PRTs )
• SRAM: 32K or 128K (512K factory-installed SRAM is also available)
• EPROM:
CM7100—32-pin DIP socket accommodates up to 512K EPROM
CM7200—128K flash EPROM at 128 bytes/sector (256K factory-
installed flash EPROM is also available)
• I/O support: six chip-select lines, supporting 64 addresses each, control
the application’s hardware
• Low electromagnetic interference
• Software written for either CM7100 or CM7200 Series is binary-
compatible with the other
Options
The CM7000 is available with two types of memory—CM7100s have
ROM and CM7200s have flash EPROM.
