COP87L40CJ/COP87L42CJ-COP87L40CJ/COP87L42CJ,One-Time Programmable (OTP) Microcontrollers with Multi-Input Wake-Up and Brown Out Detector

General Description
The COP87L40CJ/COP87L42CJ are members of the COP8TM 8-bit OTP microcontroller family. It is pin and software compatible to the mask ROM COP840CJ/COP842CJ product family. They are fully static parts, fabricated using double-metal silicon gate microCMOS technology. Features include an 8-bit memory mapped architecture, MICROWIRE/PLUSTM serial I/O, a 16-bit timer/counter with capture register, a multi-sourced interrupt, Comparator, WATCHDOGTM Timer, Modulator/Timer and Multi-Input Wakeup. Each I/O pin has software selectable options to adapt the device to the specific application. The device operates over a voltage range of 2.7V to 5.5V. High throughput is achieved with an efficient, regular instruction set operating at a 1 ms per instruction rate.
The equivalent mask programmable device contains the Brown Out detection feature. This feature is not supported on these OTP devices.
