FOR AUTOMOTIVE 105°C OPERATION
3-WIRE SERIAL E2PROM
Rev.2.1_02
The S-93C46B/56B/66B H Series is a high temperature operation 3-wire serial E2PROM for automotive components. The
S-93C46B/56B/66B H Series 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.
