Am29BDD160G

`Persistent Sector Protection
- A command sector protection method to lock combinations of individual sectors and sector groups to prevent program or erase operations within that sector (requires only VCC levels)
`Password Sector Protection
- A sophisticated sector protection method to lock combinations of individual sectors and sector groups to prevent program or erase operations within that sector using a user-definable 64-bit password
`Supports Common Flash Interface (CFI)
`Unlock Bypass Program Command
- Reduces overall programming time when issuing multiple program command sequences
`Data# Polling and toggle bits
- Provides a software method of detecting program or erase operation completion

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
0.7 V for periods of up to 20 ns. See Figure 8. 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 +0.7 V for periods up to 20 ns. See Figure 9.
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 0.7 V for periods of up to
 0 ns. See Figure 8. Maximum DC input voltage on pin A9 is +13.0 V which may overshoot to 14.0 V for periods up to 20 ns. See Figure 9.
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.
4. 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 Am29BDD160 is a 16 Megabit, 2.5 Volt-only single power supply burst mode flash memory device. Am29BDD160G can be configured for either 1,048,576 words in 16-bit mode or 524,288 double words in 32-bit mode.

The device can also be programmed in standard EPROM programmers. The device offers a configurable burst interface to 16/32-bit microprocessors and microcontrollers. To eliminate bus contention, each Am29BDD160G has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. Additional control inputs are required for synchronous burst operations: Load Burst Address Valid (ADV#), and Clock (CLK).
