1 / 10 page 1 White Electronic Designs Corporation • (602) 437-1520 • www.wedc.com White Electronic Designs W7MG1M32SVx-BN W7MG21M32SVx-BN May 2004 Rev. 2 PRELIMINARY* DESCRIPTION The W7MG1M32SVx-BN and W7MG21M32SVx-BN are organized as one and two banks of 1Mx32 respectively. The modules are based on AMDs MirrorBit™ AM29LV160M - 1Mx16 or S29AL016M (optional) Flash device in TSOP packages which are mounted on an FR4 substrate. Both modules offer access times between 70 and 120ns allowing for operation of high-speed microprocessors without wait states. FEATURES 1Mx32 and 2x1Mx32 Densities Based on AMD - AM29LV160M Flash Device Spansion™ - S29AL016M (optional) High Performance • Access time as fast as 70ns • 0.7s typical sector erase time 3V for read, erase, and program operations Flexible, Sector Architecture • One 16Kbyte, two 8Kbyte, one 32Kbyte and thirty-one 64Kbyte sectors. • Any combination of sectors can be erased • Also supports full chip erase W7MG1M32SVx-BN: 1Mx32 80 PIN SIMM W7MG21M32SVx-BN: 2x1Mx32 80 PIN SIMM 8MB/4MB (2x1Mx32 / 1Mx32) MirrorBit™ 3.0V, Boot Sector Flash Memory Module FIG. 1 – BLOCK DIAGRAMS DQ16-31 1Mx16 WE# CE# CE# Addr 0-19 DQ0-15 WE2# DQ0-15 1Mx16 WE# CE# CE0# OE# CE# Addr 0-19 Addr 0-19 DQ0-15 WE0# 1Mx16 WE# CE# CE# Addr 0-19 DQ0-15 WE2# 1Mx16 WE# CE# CE0# OE# CE# Addr 0-19 Addr 0-19 DQ0-15 WE0# DQ16-31 1Mx16 WE# CE# CE# Addr 0-19 DQ0-15 DQ0-15 1Mx16 WE# CE# CE1# CE# Addr 0-19 DQ0-15 Top boot block configurations • Bottom boot block optional.
