Microchip Technology, Inc. Memory AT49BV002T-90JC

The AT49BV002T-90JC is a 2 megabit (256K x 8) Flash memory device designed for in-system reprogrammability. It operates on a single supply voltage ranging from 2.7V to 3.6V and features a fast read access time of 90 ns. The memory is organized into a sector architecture that includes a 16K byte boot block with programming lockout, two 8K byte parameter blocks, and two main memory blocks of 96K and 128K bytes. This device supports a fast erase cycle time of 10 seconds and allows for byte-by-byte programming at a typical speed of 30 ¬µs per byte. It incorporates hardware data protection and a DATA polling feature for end-of-program detection. The AT49BV002T-90JC is characterized by low power dissipation, with an active current of 25 mA and a CMOS standby current of 50 ¬µA. It is rated for a typical endurance of 10,000 write cycles. The device is available in a 32-lead PLCC package and is suitable for commercial temperature ranges from 0¬8C to 70¬8C. It is ideal for applications requiring reliable non-volatile memory with quick access and reprogramming capabilities.
