Microchip Technology, Inc. Memory AT29LV256-15JI-T

The AT29LV256-15JI-T is a 3-volt-only Flash Programmable Erasable Read Only Memory (PEROM) with a capacity of 256K bits, organized as 32,768 words by 8 bits. It operates within a supply voltage range of 3V to 3.6V and features a fast read access time of 150 ns. The device supports low power dissipation, with an active current of 15 mA and a CMOS standby current of 40 µA. Programming is performed on a sector basis, with 512 sectors of 64 bytes each, allowing for a single cycle reprogram (erase and program) with a maximum sector program cycle time of 20 ms. The AT29LV256 includes internal address and data latches for efficient data handling and features software data protection to prevent inadvertent programming. Typical endurance exceeds 10,000 cycles, making it suitable for applications requiring reliable memory storage. The device is compatible with both CMOS and TTL logic levels, and it is available in multiple package types, including PLCC and TSOP. Its operational temperature ranges cover both commercial and industrial specifications, making it versatile for various applications.
