Oki Electric Industry MSM81C55
The MSM81C55-5 has a 2k-bit static RAM (256 bytes) with parallel I/O ports and a timer. It uses silicon gate CMOS technology and consumes a standby current of 100 micro ampere, maximum, while the chip is not selected. The parallel I/O consists of two 8-bit ports and one 6-bit port (both general purpose).| Part No. | MSM81C55 |
