The COP404LSN-5 is a member of the COPS family of N-channel silicon gate MOS technology microcontrollers. It functions as an exact circuit equivalent to the COP444L but has its internal ROM removed, allowing for external memory connection and program emulation before final production.
| Instruction Cycle Time | 16 us |
|---|---|
| Operating Voltage | 4.5V to 5.5V |
| Max Operating Supply Current | 16 mA |
| RAM Size | 128 x 4 bits |
| ROM Capacity (External) | 2048 bytes |
It is an exact circuit equivalent of the COP444L.
Yes, it is appropriate in low volume applications or when the program might be changing.
