Microchip Technology, Inc. Memory AT49BV002T-12TC

The AT49BV002T-12TC is a 2 megabit Flash Memory device from Quarktwin Technology Ltd., designed for in-system reprogrammability. It operates on a single supply voltage ranging from 2.7 to 3.6V and features a fast read access time of 120 ns. The memory is organized as 262,144 words of 8 bits and includes a sector architecture with one 16K byte boot block, 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 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-12TC 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, making it suitable for applications requiring reliable non-volatile memory storage.
