Microchip Technology, Inc. Memory AT49BV001NT-12TI

The AT49BV001NT-12TI is a 1 megabit (128K x 8) Flash memory device designed for in-system reprogrammability with a single supply voltage range of 2.7 to 3.6V. It features a fast read access time of 120 ns and supports a fast erase cycle time of 10 seconds. The memory is organized into a sector architecture that includes one 16-Kbyte boot block, two 8-Kbyte parameter blocks, and two main memory blocks (32K and 64K bytes). Programming is performed on a byte-by-byte basis with a typical time of 30 µs per byte, and the device supports up to 10,000 write cycles. It incorporates hardware data protection and a DATA polling feature for end-of-program detection. The device operates with low power dissipation, consuming 25 mA during active operation and only 50 µA in CMOS standby mode. The AT49BV001NT-12TI is suitable for applications requiring reliable non-volatile memory with efficient programming and erasing capabilities.
