The S-93C46B/56B/66B is a high speed, low current consumption, 3-wire serial E
2
PROM with a wide operating voltage
range. The S-93C46B/56B/66B has the capacity of 1 K-bit, 2 K-bit and 4 K-bit, and the organization is 64-word
16-bit,
128-word
16-bit and 256-word
16-bit. It is capable of sequential read, at which time addresses are automatically
incremented in 16-bit blocks.
The communication method is by the Microwire bus.
