COPCH842C

COP820C/COP840C Family CMOS ROM Based Microcontrollers with 1k or 2k Memory August 2000 COP820C/840C Family 8-Bit CMOS ROM Based Microcontrollers with 1k or 2k Memory General Description Note: COP8SA devices are instruction set and pinout compatible supersets of the COP800C Family devices, and are replacements for these in new designs when possible. The COP820C/840C Family ROM based microcontrollers are integrated COP8™ Base core devices with smaller memory (1k/2k), and fewer on-board features. These singlechip CMOS devices are suited for lower-functionality applications where system cost is of prime consideration.

Erasable windowed versions are available for use with a range of COP8 software and hardware development tools. Family features include an 8-bit memory mapped architecture, 10 Hz CKI with 1µs instruction cycle, one multi-function 16-bit timer/counter with PWM, MICROWIRE/PLUS™ serial I/O, power saving HALT mode, three clock modes, high current outputs, software selectable I/O options, 2.3v-6.0v operation and 20/28 pin packages.
