1, 1995 Description The Hitachi HN27C256HG is a 256-kbit ultraviolet erasable and electrically programmable ROM, featuring sub-100-ns access times.
The HN27C256HG realizes access time of 70 ns and 85 ns, employing the advanced fine process and high speed circuitry technique.
The timing conditions such as access time or output hold time are designed as same as our byte-wide SRAMs’, allowing to use with SRAMs on the same memory board by the same read timings.
So its board design in 16-bit microprocessor systems is easy.
Also, the HN27C256HG realizes faster programming time than ou...
