EEPROM Memory IC 256Kb (32K x 8) 1MHz 8-SOIC Chip IC ATMEL Original AT24C256C-SSHL-T
Description:
The AT24C256C provides 262,144 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 32,768 words of 8 bits each. The device’s cascading feature allows up to eight devices to share a common 2‑wire bus. 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‑lead SOIC, 8‑lead TSSOP, 8‑pad UDFN and 8‑ball VFBGA packages. All packages operate from 1.7V to 5.5V.
