AT28LV256-20TI

The AT28LV256-20TI is a high-performance, 256Kbit parallel Electrically Erasable and Programmable Read-Only Memory (EEPROM) from Microchip Technology. Organized as 32,768 words by 8 bits, this device offers a fast read access time of 200 ns, making it suitable for various data storage applications.

This EEPROM operates from a single 3.0V to 3.6V supply, with low power dissipation. It features automatic page write operations with internal address and data latches for 64 bytes, and an internal control timer. The write cycle time is a maximum of 10 ms for a 1- to 64-byte page write operation. Low power is achieved with a typical active current of 15 mA and a CMOS standby current of less than 20 µA when deselected.

The device is manufactured using Atmel’s advanced nonvolatile CMOS technology, ensuring high reliability with an endurance of 10,000 cycles and data retention of 10 years. It includes hardware and software data protection features, and DATA polling for end-of-write detection. The AT28LV256-20TI adheres to the JEDEC-approved byte-wide pinout and is available in a 28-TSOP package suitable for surface mounting.

It operates within a commercial and industrial temperature range of -40°C to 85°C (TC). This component is designed for applications requiring reliable non-volatile data storage with efficient power consumption and fast access times.
