| White Electronic Designs W7G1M32SVx-BN W7G21M32SVx-BN PRELIMINARY* 8MB/4MB (2x1Mx32 / 1Mx32) CMOS, Boot Sector Flash Memory Module DESCRIPTION The W7G1M32SVx-BN and W7G21M32SVx-BN are organized as one and two banks of 1Mx32 respectively. The modules are based on AMDs AM29LV160DT - 1Mx16 or STs M29W160ET (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. Embedded Erase Algorithms * Automatically preprograms and erases the chip or any combination of sectors Embedded Program Algorithms * Automatically programs and verifies data at specified address Data Polling and Toggle Bit feature for detection of program or erase cycle completion Low Power Dissipation * 30mA per Device Active Current * 10A per Device CMOS Standby Current Single 3.3V 10% Supply CMOS and TTL Compatible Inputs and Outputs Commercial and industrial operating temperature range * BNC = 0C to 70C Commercial * BNI = -40C to 85C Industrial Package * 80 Pin SIMM (JEDEC) Standard * This product is under development, is not qualified or characterized and is subject to change without notice. FEATURES 1Mx32 and 2x1Mx32 Densities Based on AMD - AM29LV160DT Flash Device STs M29W160ET (optional) Fast Read Access Time - 70ns 3.3V Only Reprogramming 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 Top boot block configurations * Bottom boot block optional.

Minimum DC voltage on input or I/O pins is -0.5 V. During voltage transitions, input or I/O pins may overshoot VSS to -2.0 V for periods of up to 20 ns. See Figure 7. Maximum DC voltage on input or I/O pins is VCC +0.5 V. During voltage transitions, input or I/O pins may overshoot to VCC +2.0 V for periods up to 20 ns. See Figure 8. 2. Minimum DC input voltage on pins A9, OE#, and RESET# is -0.5 V. During voltage transitions, A9, OE#, and RESET# may overshoot VSS to -2.0 V for periods of up to 20 ns. See Figure 7. Maximum DC input voltage on pin A9 is +12.5 V which may overshoot to 14.0 V for periods up to 20 ns. 3. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one second. Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this data sheet is not implied. Exposure of the device to absolute maximum rating conditions for extended periods may affect device reliability.
