www.DataSheet4U.com Rev.2.1_00 CMOS SERIAL E2PROM S-93A46A/56A/66A The S-93A46A/56A/66A is a high-temperature operation, high speed, low current consumption, 1 Kbit, 2 K-bit and 4 K-bit serial E2PROM with a wide operating voltage range. It is organized as 64-word × 16-bit, 128-word × 16-bit and 256-word × 16-bit in each. It is capable of sequential read, at which time addresses are automatically incremented in 16-bit blocks. The instruction code is compatible with the NM93CS46/56/66.
