AM29F040B-90PF, Flash Memory, DIP-32

The AM29F040B-90PF is a high-performance 4 Megabit (512 K x 8-bit) Flash Memory developed by AMD, designed for 5V-only read and write operations. Built on advanced 0.35 µm CMOS technology, it is compatible with previous 0.5 µm Am29F040 devices, ensuring a seamless upgrade path.

With a 90ns access time, this flash memory supports high-speed microprocessor applications without the need for wait states. It features low power consumption with typical active read and program/erase currents of 20mA and 30mA, respectively, and a standby current of 1µA for energy-efficient systems.

The device incorporates a flexible sector architecture, dividing the memory into eight uniform 64KB sectors, enabling sector-specific erase operations. Additionally, it includes hardware sector protection to lock sectors against unintended program or erase operations. Embedded algorithms ensure reliable and automated programming and erasing processes, reducing the load on the host system.

Compatible with JEDEC Flash memory standards, the AM29F040B-90PF supports a range of microprocessor interfaces and is packaged in a DIP-32 configuration for easy integration. The device is an excellent choice for applications like embedded systems, industrial controls, and communication equipment, offering both reliability and cost efficiency.
