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 COP8TM 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. Pin and software compatible (different VCC range) 4k/32k OTP verDevice COP620C COP820C COP920C COP622C COP822C COP922C COP640C COP840C COP940C COP642C COP842C COP942C Memory (bytes) 1k ROM 1k ROM 1k ROM 1k ROM 1k ROM 1k ROM 2k ROM 2k ROM 2k ROM 2k ROM 2k ROM 2k ROM RAM (bytes) 64 64 64 64 64 64 128 128 128 128 128 128 I/O Pins 24 24 24 16 16 16 24 24 24 16 16 16 sions are available (COP87LxxCJ/RJ Family). Erasable windowed versions are available for use with a range of COP8 software and hardware development tools.

Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open. Note 4: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to VCC, L and G0 -- G5 configured as outputs and set high. The D port set to zero. Note 5: Except pin G7: +100 mA, -25 mA (COP920C only). Sampled and not 100% tested. Pins G6 and RESET are designed with a high voltage input network for factory testing. These pins allow input voltages greater than VCC and the pins will have sink current to VCC when biased at voltages greater than VCC (the pins do not have source current when biased at a voltage below VCC). The effective resistance to VCC is 750 (typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
