Microchip Technology, Inc. Memory AT29LV020-25TC

The AT29LV020-25TC is a 2-megabit (256K x 8) Flash memory device designed for 3-volt-only operation, with a supply voltage range of 3V to 3.6V. It features a fast read access time of 100 ns and a sector program cycle time of 20 ms. The memory is organized into 1024 sectors of 256 bytes each, allowing for single-cycle reprogramming. It includes two 8K-byte boot blocks with lockout protection and supports software data protection to prevent inadvertent programming. The device has a low active current of 15 mA and a standby current of 40 ¬µA, making it suitable for low-power applications. It is compatible with both CMOS and TTL logic levels, and it operates over commercial (0¬8C to 70¬8C) and industrial (-40¬8C to 85¬8C) temperature ranges. The AT29LV020-25TC also features data polling for end-of-program detection and has a typical endurance of over 10,000 write cycles per sector. This memory device is packaged in a 32-lead Thin Small Outline Package (TSOP).
