It provides pro- tection for the storage and update of code and data in addition to adding system design flexibility through five general purpose inputs. Two interface modes are sup- ported by the SST49LF00xA: Firmware Hub (FWH) Interface Mode for In-System programming and Parallel Programming (PP) Mode for fast factory programming of PC-BIOS applications. The SST49LF00xA flash memory devices are manufac- tured with SST’s proprietary, high performance Super- Flash Technology. The split-gate cell design and thick oxide tunneling injector attain better reliability and manu- facturability compared with alternate approaches. The SST49LF00xA devices significantly improve performance and reliability, while lowering power consumption. The SST49LF00xA devices write (Program or Erase) with a single 3.0-3.6V power supply. It uses less energy during Erase and Program than alternative flash memory tech- nologies. The total energy consumed is a function of the applied voltage, current and time of application. Since for 2 Mbit / 3 Mbit / 4 Mbit / 8 Mbit Firmware Hub SST49LF002A / SST49LF003A / SST49LF004A / SST49LF008A SST49LF002A / 003A / 004A / 008A2 Mb / 3 Mb / 4 Mb / 8 Mb Firmware Hub for Intel 8xx Chipsets |
