Reduce Pin Count to ASIC and Enhance System Reliability
Manufacturers of video graphic accelerator cards, hard disk drives, digital cameras, MP3s, white appliances, wireless LAN cards, smart cards and voice recorders can use PMC’s Pm25LV series SPI Serial Flash products for high-performance code and data storage applications.
The Pm25LV SPI Serial Flash product line fulfills the market requirement for low-cost, high-performance synchronous flash applications. The Pm25LV is enabled through the Chip Enable pin (CE#) and accessed via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All write cycles are completely self-timed.
Pm25LV also offers exceptional quality with unparallel endurance, lower power consumption, flexible in-system programming capability, fast program and erase features – all in a space-saving 8-pin SOIC package.
pFLASH Architecture: Inherent Advantages
Based on pFLASH®, PMC’s proprietary, NOR-based P-Channel flash architecture, Pm25LV SPI Serial Flash products offer a flexible array architecture, faster programming and lower power consumption while virtually eliminating over-erase, program disturb, read disturb and data retention issues in comparison to alternative flash solutions.
Pm25LV SPI Serial Flash products also lower the overall cost of production through faster product development, ease of system qualification and simplified inventory logistics. They facilitate rapid release of new products by enabling flexible in-system programming capabilities.
Highest Performance and Production Throughput
Pm25LV SPI Serial Flash’s fast 25MHz clock rate and zero wait state eliminate the need for extra clock cycles required by alternative SPI serial flash solutions and simplify the hand-shaking procedures required between logic and flash. Manufacturers can improve product performance and increase throughput on the production line with less than 40 milliseconds erase and 2 milliseconds program times.
PMC SPI Serial Flash Solutions offer the highest data retention and most durable architecture.
