COP8FG Datasheet, PDF (1/59 Pages) National Semiconductor (TI) – 8-Bit CMOS ROM Based and OTP Microcontrollers with 8k to 32k Memory, Two Comparators and USART

July 1999

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 COP8â¢ Feature core devices with 8k to

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.

Erasable windowed 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, 15 MHz CKI with 0.67 Âµs instruction cycle, 14 inter-

rupts, three multi-function 16-bit timer/counters with PWM,

full duplex USART, MICROWIRE/PLUSâ¢, two analog com-

parators, two power saving HALT/IDLE modes, MIWU, idle

timer, on-chip R/C oscillator, high current outputs, user se-

lectable options (WATCHDOGâ¢, 4 clock/oscillator modes,

power-on-reset), 4.5V to 5.5V operation, program code se-

curity, and 28/40/44 pin packages.
