Am8156 - 2048-Bit Static MOS RAM

Download the Am8156 datasheet PDF. This datasheet also covers the Am8155 variant, as both devices belong to the same 2048-bit static mos ram family and are provided as variant models within a single manufacturer datasheet.

General Description

The Am8155 and Am8156 are RAM and I/O chips to be used in the Am8085A MPU system.

The RAM portion is designed with 2K bit static cells organized as 256 x 8.

They have a maximum access time of 400ns to permit use with no wait states in Am8085A CPU.
