COP404C ROMless CMOS Microcontrollers

The COP404C ROMless Microcontroller is a member of the COPSTM family, 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 pins, to function as a COP444C, a COP424C, or a 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. By National Semiconductor Corporation
