Memory Products 11 Parallel Flash Parallel Flash Multi-Purpose Flash Devices (MPF™ Devices) Multi-Purpose Flash Plus Devices (MPF+ Devices) 39 Series Multi-Purpose Flash and Multi-Purpose Flash Plus make up a family of Parallel Flash memory products that deliver high performance, low-power consumption, superior reliability and small sector size. Based on Microchip’s SuperFlash technology, MPF and MPF+ provide faster program, erase and read times than conventional Flash, thereby saving power consumption and increasing manufacturing throughput. In addition to offering 3 V and 5 V memory products, MPF devices and MPF+ devices provide 1.8 V that deliver significant power savings compared to industry standard Flash. Ideal for space-constrained applications, this family offers the industry’s smallest standard packages, the XFLGA and WFBGA, both as small as 4 × 6 mm. Advanced Multi-Purpose Flash Plus Devices (Advanced MPF+ Devices) 38 Series Advanced MPF+ memory devices incorporate advanced security and protection features, page read access and better write programming into the standard MPF+ family. Currently these devices are available on 64 Mbit only. Parallel Flash Applications ■ Bluetooth ■ Servers and routers ■ GPS ■ Set-top boxes ■ Wi-Fi/WiMax ■ Digital cameras ■ Mobile phones ■ Industrial ■ DSL/cable modems ■ Automotive infotainment *Data varies for different devices, please refer to the datasheet for details.
