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
• 10µA per Device CMOS Standby Current
Single 3.3V ±10% Supply

Notes:
1.
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.
