COP8FG Family

8-Bit CMOS ROM Based and OTP Microcontrollers with

8k to 32k Memory, Two Comparators and USART

General Description

Note: COP8FG devices are 15 MHz versions of the

COP8SG devices.

The COP8FGx5 Family ROM based microcontrollers are

highly integrated COP8

32k memory and advanced features including Analog com-

parators, and zero external components. These single-chip

CMOS devices are suited for more complex applications re-

quiring a full featured controller with larger memory, low EMI,

two comparators, and a full-duplex USART. COP8FGx7 de-

vices are 100% form-fit-function compatible 8k or 32k OTP

(One Time Programmable) versions for use in production or

development.

Key Features

n Low cost 8-bit microcontroller

n Quiet Design (low radiated emissions)

n Multi-Input Wakeup pins with optional interrupts (8 pins)

n Mask selectable clock options

n Internal Power-On-Reset — user selectable

n WATCHDOG and Clock Monitor Logic — user selectable

n Eight high current outputs

n 256 or 512 bytes on-board RAM

n 8k to 32k ROM or OTP EPROM with security feature

CPU Features

n Versatile easy to use instruction set

n 0.67 µs instruction cycle time

n Fourteen multi-source vectored interrupts servicing
