COP404C ROMless CMOS Microcontrollers is a product of National Semiconductor Corporation. It is an accurate emulation of the COP444C, COP424C and COP410C. The product has the lowest power consumption, static, power-saving IDLE state and HALT mode, 4 ms instruction time, 128c4 RAM, 2k c 8 ROM address, true vector interrupt, three-level subroutine stack and single-thread function.
The COP404C is a member of the COPS family of mask-programmed CMOS parts. It contains CPU, RAM, and I/O but lacks internal ROM. Instead, it has added pins to output ROM addresses and input ROM data, allowing it to be configured as a COP444C, COP424C, or COP410C.
| Operating Voltage | 2.4V to 5.5V |
|---|---|
| RAM Size | 128 bytes |
| Instruction Cycle Time (Max) | 16 ms |
