COP404C ROMless CMOS Microcontrollers

General Description

Features

Accurate emulation of the COP444C, COP424C and

COP410C

The COP404C ROMless Microcontroller is a member of the

COPS^TMfamily, fabricated using double-poly, silicon gate

CMOS (microCMOS) technology. The COP404C contains

CPU, RAM, I/O and is identical to a COP444C device ex-

cept the ROM has been removed and pins have been add-

ed to output the ROM address and to input the ROM data.

The COP404C can be configured, by means of external

Lowest Power Dissipation (50 mW typical)

Fully static (can turn off the clock)

Power saving IDLE state and HALT mode

4 ms instruction time, plus software selectable clocks

pins, to function as

a COP444C, a COP424C, or a

True vectored interrupt, plus restart

Three-level subroutine stack

COP410C. Pins have been added to allow the user to select

the various functional options that are available on the fami-

ly of mask-programmed CMOS parts. The COP404C is pri-

marily intended for use in the development and debug of a

COP program for the COP444C/445C, COP424C/425C,

and COP410C/411C devices prior to masking the final part.

The COP404C is also appropriate in low volume applica-

tions or when the program might be changing.

Single supply operation (2.4V to 5.5V)

Programmable read/write 8-bit timer/event counter

Internal binary counter register with MICROWIRE^TM

serial I/O capability

General purpose and TRI-STATE outputs

LSTTL/CMOS compatible

MICROBUS^TMcompatible

Software/hardware compatible with other members of

the COP400 family
