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 V_SS to 2.0 V for periods of up to 20 ns. Maximum DC voltage on input or I/O pins is V_CC +0.5 V. See Figure 9. During voltage transitions, input or I/O pins may overshoot to V_CC +2.0 V for periods up to 20 ns. See Figure 10.
2. Minimum DC input voltage on pins A9, OE#, RESET#, and WP#/ACC is 0.5 V. During voltage transitions, A9, OE#, WP#/ACC, and RESET# may overshoot V_SS to 2.0 V for periods of up to 20 ns. See Figure 9. Maximum DC input voltage on pin A9 is +12.5 V which may overshoot to +14.0 V for periods up to 20 ns. Maximum DC input voltage on WP#/ACC is +12.6 V which may overshoot to +12.0 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.

The Am29PDS322D is a 32 Mbit, 1.8 V-only Flash memory organized as 2,097,152 words of 16 bits each. This device is offered in a 48-ball FBGA package. The device is designed to be programmed in system with standard system 1.8 V V_CC supply. This device can also be reprogrammed in standard EPROM programmers.

The Am29PDS322D offers fast page access time of 40 ns with random access time of 100 ns (at 1.8 V to 2.2 V V_CC), allowing operation of high-speed microprocessors without wait states. To eliminate bus contention the device has separate chip enable (CE), write  enable (WE), and output enable (OE) controls. The page size is 4 words.

The device requires only a single 1.8 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations.
