The AT28BV256-20TU from Atmel is a high-performance, 256Kbit electrically erasable and programmable read-only memory (EEPROM). Organized as 32,768 words by 8 bits, this non-volatile memory offers a fast read access time of 200 ns and operates on a single supply voltage ranging from 2.7V to 3.6V.
This device supports automatic page write operations, allowing for the internal latching of up to 64 bytes of data, which frees up the address and data bus during write cycles. It features low power dissipation with an active current of 15 mA and a CMOS standby current of less than 200 µA. The AT28BV256-20TU is manufactured using advanced nonvolatile CMOS technology, ensuring high reliability with an endurance of 10,000 cycles and data retention of 10 years.
Packaged in a 28-TSOP (Surface Mount) configuration, this EEPROM is designed for industrial temperature ranges of -40°C to 85°C. It includes hardware and software data protection features and utilizes data polling for end-of-write detection. The device also offers a green (Pb/Halide-free) packaging option.
