COP87LxxCJ/RJ Family 8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory and Comparator
General Description
The COP87LxxCJ/RJ Family OTP (One Time Programmable) microcontrollers are integrated COP8TM Base core devices with 4k or 32k memory, and an Analog comparator (no brownout). These multi-chip CMOS devices are suited for lower-functionality applications, and as pre-production devices for a ROM design. Low cost, pin and software compatible (plus Brownout) 1k or 2k ROM versions are available (COP820CJ/840CJ Family). 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 MHz CKI with 1µs instruction cycle, three clock opDevice COP87L20CJ COP87L22CJ COP87L40CJ COP87L42CJ COP87L40RJ COP87L42RJ Memory (bytes) 4k OTP EPROM 4k OTP EPROM 4k OTP EPROM 4k OTP EPROM 32k OTP EPROM 32k OTP EPROM RAM (bytes) 64 64 128 128 128 128 tions (-1 = crystal; -2 = external; -3 = internal RC), one multifunction 16-bit timer/counter, MICROWIRE/PLUSTM serial I/O, one analog comparator, power saving HALT mode with multi-sourced wakeup/interrupt capability, on-chip R/C oscillator capacitor, high current outputs, software selectable I/O options, WATCHDOGTM timer, modulator/timer, Power on Reset, program code security, 2.7V to 5.5V operation and 20/28 pin packages.

DC Electrical Characteristics
(Continued)
Note 4: The HALT mode will stop CKI from oscillating in the RC and crystal configurations by bringing CKI high. HALT test conditions: L, and G0..G5 ports configured as outputs and set high. The D port set to zero. All inputs tied to VCC. The comparator is disabled. Note 5: The user must guarantee that D2 pin does not source more than 10 mA during RESET. If D2 sources more than 10 mA during reset, the device will go into programming mode. Note 6: Pins G6 and RESET are designed with a high voltage input network. 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.
