Am29DL320G

SOFTWARE FEATURES
Data Management Software (DMS)
- AMD-supplied software manages data programming,enabling EEPROM emulation
- Eases historical sector erase flash limitations
Supports Common Flash Memory Interface (CFI)
Erase Suspend/Erase Resume
- Suspends erase operations to allow reading from other sectors in the same bank
Data# Polling and Toggle Bits
- Provides a software method of detecting the status of program or erase cycles
Unlock Bypass Program command
- Reduces overall programming time when issuing multiple program command sequences
HARDWARE FEATURES
Any combination of sectors can be erased
Ready/Busy# output (RY/BY#)
- Hardware method for detecting program or erase cycle completion
Hardware reset pin (RESET#)
- Hardware method of resetting the internal state machine to the read mode
WP#/ACC input pin
- Write protect (WP#) function allows protection of two outermost boot sectors, regardless of sector protect status
- Acceleration (ACC) function accelerates program timing
Sector protection
- Hardware method of locking a sector, either in-system or using programming equipment, to prevent any program or erase operation within that sector
- Temporary Sector Unprotect allows changing data in protected sectors in-system

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. Maximum DC voltage on input or I/O pins is V_CC +0.5 V.See Figure 8. During voltage transitions, input or I/O pins may overshoot to V_CC +2.0 V for periods up to 20 ns. See Figure 9.
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 8. 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 +9.5 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 Am29DL320G is a 32 megabit, 3.0 volt-only flash memory device, organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. Word mode data appears on DQ15DQ0; byte mode data appears on DQ7DQ0. Am29DL320G is designed to be programmed in-system with the standard 3.0 volt VCC supply, and can also be programmed in standard EPROM programmers.

The device is available with an access time of 70, 90,or 120 ns. The devices are offered in 48-pin TSOP,48-ball or 63-ball FBGA packages, and 64-ball Fortified BGA. Standard control pins-chip enable (CE#),write enable (WE#), and output enable (OE#)-control normal read and write operations, and avoid bus contention issues.

Am29DL320G requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations.
