Microchip Technology's SST39VF800A-90-4C-EK Flash Memory

The SST39VF800A-90-4C-EK is a high-performance CMOS Multi-Purpose Flash Plus (MPF+) memory manufactured by Microchip Technology. This device offers a storage capacity of 8 Mbit (1M x 8-bit / 512K x 16-bit) and is designed to provide both reliability and flexibility for a wide range of applications. Its 90 nanosecond access time ensures swift read operations, making it an ideal choice for embedded systems that require quick data retrieval.

One of the standout features of the SST39VF800A-90-4C-EK is its compatibility with the industry-standard JEDEC single power supply Flash interface. This ensures easy integration into existing designs without the need for extensive re-engineering. The memory operates on a single power supply voltage of 2.7V to 3.6V, which makes it suitable for low-power applications and portable devices.

This flash memory chip is organized as either 1M x 8 or 512K x 16, which allows for flexible memory access. It supports both byte and word programming, providing versatility for different kinds of data storage. The SST39VF800A-90-4C-EK is designed with a sector-erase architecture that provides a uniform 2 KWord (4 KByte) sector throughout the entire memory array. This feature simplifies the task of erasing data in specific areas without affecting the rest of the memory, which is particularly beneficial for systems that frequently update their firmware or data.

Additionally, the SST39VF800A-90-4C-EK offers end-of-write detection features such as Data# Polling, Toggle Bit, and Ready/Busy# status, which help in providing feedback on the completion of write cycles. This is crucial for systems that need to ensure data integrity and reliability during the write process.

For development and prototyping, the SST39VF800A-90-4C-EK is available in a TSOP (Thin Small Outline Package) form factor, which is suitable for PC boards with space constraints. Microchip Technology's commitment to quality means this product is designed to meet high standards, ensuring that it can withstand the demands of rigorous applications.

In summary, the SST39VF800A-90-4C-EK from Microchip Technology is a versatile and reliable flash memory solution that offers fast access time, low power consumption, and a user-friendly interface, making it a top choice for designers and engineers across various industries.
