The AT49LV040-90JC is a 4-megabit (512K x 8) Flash memory manufactured by Microchip Technology. It operates with a single 2.7V to 3.6V supply for both read and write operations, offering a fast read access time of 70 ns. The device features internal program control and timer, a 16K byte boot block with lockout, and hardware data protection.
Programming is performed byte-by-byte with a typical time of 30 µs/byte. The end of a program cycle can be detected using Data Polling. The memory supports typical 10,000 write cycles and has low power dissipation, drawing 25 mA active current and 50 µA CMOS standby current. It is available in a small 8 x 14 mm VSOP/TSOP or 32-PLCC package.
This Flash memory is suitable for applications requiring in-system reprogrammability without high input voltages. The boot block section can be permanently protected from reprogramming if enabled, ensuring data integrity for user-secure code.
