1 / 28 page COP87LxxCJ/RJ Family 8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory and Comparator General Description The COP87LxxCJ/RJ Family OTP (One Time Program- mable) microcontrollers are integrated COP8™ 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 com- patible (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 architec- ture, 10 MHz CKI with 1µs instruction cycle, three clock op- tions (-1 = crystal; -2 = external; -3 = internal RC), one multi- function 16-bit timer/counter, MICROWIRE/PLUS™ serial I/O, one analog comparator, power saving HALT mode with multi-sourced wakeup/interrupt capability, on-chip R/C oscil- lator capacitor, high current outputs, software selectable I/O options, WATCHDOG™ timer, modulator/timer, Power on Reset, program code security, 2.7V to 5.5V operation and 20/28 pin packages. In this datasheet, the term COP87L20CJ refers to the COP87L20CJ, and COP87L22CJ. COP840CJ refers to the COP87L40CJ, COP87L42CJ, COP87L40RJ, and COP87L42RJ. Devices included in this datasheet are: Device Memory (bytes) RAM (bytes) I/O Pins Packages Temperature COP87L20CJ 4k OTP EPROM 64 24 28 DIP/SOIC -40 to +85˚C COP87L22CJ 4k OTP EPROM 64 16 20 DIP/SOIC -40 to +85˚C COP87L40CJ 4k OTP EPROM 128 24 28 DIP/SOIC -40 to +85˚C COP87L42CJ 4k OTP EPROM 128 16 20 DIP/SOIC -40 to +85˚C COP87L40RJ 32k OTP EPROM 128 24 28 DIP/SOIC -40 to +85˚C COP87L42RJ 32k OTP EPROM 128 16 20 DIP/SOIC -40 to +85˚C Key Features n Multi-Input Wakeup (on the 8-bit Port L) n Analog comparator n Modulator/Timer (high speed PWM timer for IR transmission) n 16-bit multi-function timer supporting — PWM mode — External event counter mode — Input capture mode n Integrated capacitor for the R/C oscillator n 4 or 32 kbyte on-board OTP EPROM with security feature n 64 or 128 bytes on-chip RAM I/O Features n Software selectable I/O options (TRI-STATE®, Push-Pull, Weak Pull-Up Input, High Impedance Input) n High current outputs (8 pins) n Schmitt trigger inputs on Port G n MICROWIRE/PLUS serial I/O n Packages: — 20 DIP/SO with 16 I/O pins — 28 DIP/SO with 24 I/O pins CPU/Instruction Set Features n 1 µs instruction cycle time n Three multi-source interrupts servicing — External interrupt with selectable edge — Timer interrupt — Software interrupt n Versatile and easy to use instruction set n 8-bit stack pointer (SP) — stack in RAM n Two 8-bit Register Indirect Data Memory Pointers (B and X) Fully Static CMOS n Low current drain (typically <1 µA) n Single supply operation: 2.7V to 5.5V n Temperature range: −40˚C to +85˚C Development Support n Emulation device for the COP820CJ/COP840CJ n Real time emulation and full program debug offered by MetaLink Development Systems TRI-STATE® is a registered trademark of National Semiconductor Corporation.
