Product Preview
The RCA-COP 1831 and COP1831C types are 4096-bit mask-programmable CMOS read-only memories organized as 512 words x 8 bits and are com pletely static; no clocks required. They will directly interface with COP1800-series micro-processors without additional components.
The COP1831 and COP1831C respond to 16-bit address multiplexed on 8 address lines. Addr.
