The SST39SF040-45-4I-NHE is a high-performance CMOS Multi-Purpose Flash (MPF) memory manufactured by Microchip Technology. It is a 4 Mbit, 512K x 8-bit, non-volatile flash memory device, with a fast read access time of 45 ns, making it ideal for a wide range of computing, embedded, telecommunications, and industrial applications.
This flash memory device operates on a single 4.5V to 5.5V power supply, which is suitable for standard 5V systems, and features low power consumption with typical active current of 10 mA and standby current of 10 µA, contributing to its efficiency in battery-powered devices. The SST39SF040-45-4I-NHE is designed for high reliability and endurance, with a minimum of 100,000 erase/write cycles guaranteed per sector and data retention of over 100 years.
One of the key attributes of the SST39SF040-45-4I-NHE is its sector-erase and block-erase capabilities, allowing users to flexibly manage data storage and updates. The device is organized into 8 independent sectors, each containing 64K bytes, and 2 blocks, each containing 128K bytes. The sector-erase function can erase one sector in typical 18 ms, while the block-erase function can erase one block in typical 18 ms, or the entire chip in typical 70 ms.
Program operation is also highly efficient, with a typical byte-program time of 14 µs. The device supports auto address increment which reduces the overall programming time for multiple bytes. The SST39SF040-45-4I-NHE offers flexible use with its compatibility with JEDEC standards and is available in a 32-lead PLCC package, ensuring easy integration into various system designs.
With its robust design and compatibility with industry standards, the SST39SF040-45-4I-NHE from Microchip Technology is a reliable choice for developers looking for a flash memory solution that offers both performance and flexibility.
