FOR AUTOMOTIVE 125°C OPERATION
3-WIRE SERIAL E2PROM
Rev.1.2_00
This IC is a high temperature operation 3-wire serial E2PROM for automotive components. This IC has the capacity of 1 K-bit,
2 K-bit, 4 K-bit, 8 K-bit and 16 K-bit, and the organization is 64 words × 16-bit, 128 words × 16-bit, 256 words × 16-bit, 512
words × 16-bit and 1024 words × 16-bit, respectively. Sequential read is available, at which time addresses are automatically
incremented in 16-bit blocks. The communication method is by the Microwire bus.
Caution Before using the product in automobile control unit or medical equipment, contact to SII Semiconductor
Corporation is indispensable.
