125°C OPERATION 3-WIRE SERIAL
E2PROM FOR AUTOMOTIVE
Rev.6.1_00
The S-93A46A/56A/66A is a high temperature operation 3-wire serial E2PROM for automotive components. The S-
93A46A/56A/66A 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.
