The AT29LV040A-15JU from Atmel is a 4-megabit (512K x 8) in-system Flash Programmable and Erasable Read-Only Memory (PEROM). Designed for 3-volt only operation, it supports both read and write functions within this voltage range, simplifying system design. The device provides a fast read access time of 150 ns and features low power consumption, with an active current of 15 mA and a CMOS standby current of less than 50 µA.
Programming is performed on a sector basis, with 2048 sectors each containing 256 bytes. This allows for efficient in-system reprogramming without requiring high programming voltages. The device includes internal address and data latches for 256 bytes, enabling the microprocessor to perform other operations during the programming cycle. Data Polling on I/O7 can be used to detect the end of a program cycle. The AT29LV040A-15JU offers typical endurance exceeding 10,000 cycles per sector and is compatible with CMOS and TTL logic levels.
Available in 32-lead PLCC and 32-lead TSOP (Type 1) packages, this Flash memory is suitable for surface mount applications. It also offers a green (Pb/Halide-free) packaging option.
