General Description
AT24CS256 General Description
The AT24CS128/256 provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8bits each. The device's cascadable feature allows up to 4 devices to share a common 2-wire bus. The device also features a one-time programmable 2048 bit array, which once enabled, becomes read-only and cannot be overwritten. If not enabled, the OTP section will function as part of the normal memory array. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The devices are available in space-saving 8-pin JEDEC PDI (AT24CS128/256), 8-pin EIAJ (AT24CS128/256), 8-pin JEDEC SOIC (AT24CS128) packages. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.
