    3.0V to 3.6V 8Mbit LPC Firmware Flash

     

    产品信息

    The SST49LF008A flash memory devices are designed to be read-compatible with the Intel 82802 Firmware Hub (FWH) device for PC-BIOS application. These devices provide protection 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 supported by the SST49LF008A: Firmware Hub (FWH) Interface mode for in-system programming and Parallel Programming (PP) mode for fast factory programming of PC-BIOS applications.

       Firmware Hub for Intel 8xx Chipsets

       8 Mbit SuperFlash memory array for code/datastorage– 1024K x8

       Flexible Erase Capability– Uniform 4 KByte Sectors– Uniform 64 KByte overlay blocks– 64 KByte Top Boot Block protection– Chip-Erase for PP Mode Only

       Single 3.0-3.6V Read and Write Operations

       Superior Reliability– Endurance:100,000 Cycles (typical)– Greater than 100 years Data Retention

       Low Power Consumption– Active Read Current: 6 mA (typical)– Standby Current: 10 µA (typical)

       Fast Sector-Erase/Byte-Program Operation

      Sector-Erase Time: 18 ms (typical)

       Block-Erase Time: 18 ms (typical)

      Chip-Erase Time: 70 ms (typical)

      Byte-Program Time: 14 µs (typical)

      Chip Rewrite Time: 15 seconds (typical)

      Single-pulse Program or Erase– Internal timing generation

       Two Operational Modes– Firmware Hub Interface (FWH) Mode forIn-System operation– Parallel Programming (PP) Mode for fastproduction programming

       Firmware Hub Hardware Interface Mode– 5-signal communication interface supportingbyte Read and Write– 33 MHz clock frequency operation– WP# and TBL# pins provide hardware writeprotect for entire chip and/or top Boot Block– Block Locking Register for all blocks– Standard SDP Command Set– Data# Polling and Toggle Bit for End-of-Writedetection– 5 GPI pins for system design flexibility– 4 ID pins for multi-chip selection

       Parallel Programming (PP) Mode– 11-pin multiplexed address and8-pin data I/O interface– Supports fast In-System or PROM programmingfor manufacturing

       CMOS and PCI I/O Compatibility

       Packages Available– 32-lead PLCC– 32-lead TSOP (8mm x 14mm)– 40-lead TSOP (10mm x 20mm)– Non-Pb (lead-free) packages available

       All non-Pb (lead-free) devices are RoHS compliant
