HD63310, Smart Dual Port RAM

HD63310 5- DPRAM (Smart Dual Port RAM) The HD63310 (S-DPRAM) is a high intelligent DPRAM, which provide a communication path between multiprocessor systems.

The HD63310 has 1024 x 8 bit RAM, 62 x 8 bit registers and individual dual I/O ports.

The dual ports perform read/ write operations independently and simultaneously.

User can select one of the two mode (DPRAM or FIFO mode) by t)l.e program.
