The AT49BV040B-JU is a 4 megabit (512K x 8) in-system reprogrammable Flash Memory manufactured by Microchip Technology. It operates with a single supply voltage ranging from 2.7V to 5.5V, offering flexibility for various applications.
This Flash Memory provides a fast read access time of 70 ns at 2.7V to 3.6V and 55 ns at 4.5V to 5.5V. It supports byte-by-byte programming with a typical time of 10 µs/byte and has a minimum of 100,000 write cycles. The device features a flexible sector architecture, including a 16K byte boot sector with programming lockout, two 8K byte parameter sectors, and eight main memory sectors.
Designed for in-system reprogrammability, the AT49BV040B-JU does not require high input voltages for programming. It utilizes standard CE, OE, and WE inputs for data access. The memory array can be erased via chip erase or sector erase command sequences. The end of program or erase cycles can be detected using DATA polling or the toggle bit feature.
The AT49BV040B-JU is available in a 32-lead PLCC (J-Lead) package, suitable for surface mounting. It operates within an industrial temperature range of -40°C to 85°C.
