CMOS SERIAL E2PROM
S-29XX0A Series
The S-29XX0A Series is high speed, low power 1K/2K/4K-bit E2PROM with a wide operating voltage range. They are organized as 64-word 16-bit, 128-word 16-bit and 256-word 16-bit, respectively. Each is capable of sequential read, at which time addresses are automatically incremented in 16-bit blocks. The instruction code is compatible with the NM93CSXX Series.
Features
Standby : 1.0 A Max. (VCC=6.5 V) Operating : 0.8 mA Max. (VCC=5.5 V) : 0.4 mA Max. (VCC=2.5 V) W rite Read : 2.5 to 6.5 V : 1.8 to 6.5 V
Endurance : 10 cycles/word Data retention : 10 years S-29130A : 1K bits NM93CS46 instruction code compatible S-29220A : 2K bits NM93CS56 instruction code compatible S-29230A : 2K bits CAT35C102 instruction code compatible S-29330A : 4K bits NM93CS66 instruction code compatible
