Overview - S-93C46B/56B/66B H Series

105°C OPERATION 3-WIRE SERIAL EEPROM FOR AUTOMOTIVE S-93C46B/56B/66B H Series (1K/2K/4K-bit)

The S-93C46B/56B/66B H Series is a high temperature operation 1/2/4 K-bit 3-wire serial E2PROM for automotive components. It is organized as 64-word × 16-bit, 128-word × 16-bit, 256-word × 16-bit, respectively. Each is capable of sequential read, at which time addresses are automatically incremented in 16-bit blocks. The communication method is by the Microwire bus.
