Am29LV400B
4 Megabit (512 K x 8-Bit/256 K x 16-Bit)
CMOS 3.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
— Full voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications
— Regulated voltage range: 3.0 to 3.6 volt read and write operations for compatibility with high
performance 3.3 volt microprocessors
■ Manufactured on 0.32 µm process technology
— Compatible with 0.5 µm Am29LV400 device
■ High performance
— Full voltage range: access times as fast as 70 ns
— Regulated voltage range: access times as fast as 55 ns
■ Ultra low power consumption (typical values at 5 MHz)
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 7 mA read current
— 15 mA program/erase current
■ Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and seven 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and seven 32 Kword sectors (word mode)
— Supports full chip erase
— Sector Protection features:
A hardware method of locking a sector to prevent any program or erase operations within that sector
Sectors can be locked in-system or via programming equipment
Temporary Sector Unprotect feature allows code changes in previously locked sectors
■ Unlock Bypass Program Command
— Reduces overall programming time when issuing multiple program command sequences
■ Top or bottom boot block configurations available
■ Embedded Algorithms
— Embedded Erase algorithm automatically preprograms and erases the entire chip or any
combination of designated sectors
— Embedded Program algorithm automatically writes and verifies data at specified addresses
■ Minimum 1,000,000 write cycle guarantee per sector
■ 20-year data retention at 125°C
— Reliable operation for the life of the system
■ Package option
— 48-ball FBGA
— 48-pin TSOP
— 44-pin SO
■ Compatibility with JEDEC standards
— Pinout and software compatible with singlepower supply Flash
— Superior inadvertent write protection
■ Data# Polling and toggle bits
— Provides a software method of detecting program or erase operation completion
■ Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting program or erase cycle completion
■ Erase Suspend/Erase Resume
— Suspends an erase operation to read data from, or program data to, a sector that is not being
erased, then resumes the erase operation
■ Hardware reset pin (RESET#)
— Hardware method to reset the device to reading array data

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.
