DATA SHEET
Am29SL400C
4 Megabit (512 K x 8-Bit/256 K x 16-Bit) CMOS 1.8
Volt-only Super Low Voltage Flash Memory
Distinctive Characteristics
■ Single power supply operation
■ Embedded Algorithms
— 1.65 to 2.2 V for read, program, and erase operations
— Ideal for battery-powered applications
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
■ Manufactured on 0.32 µm process technology
— Embedded Program algorithm automatically writes
and verifies data at specified addresses
■ High performance
— Access times as fast as 100 ns
■ Minimum 1,000,000 erase cycle guarantee per
■ Ultra low power consumption (typical values at
sector
5 MHz)
■ 20-year data retention at 125°C
— 1 µA Automatic Sleep Mode current
— 1 µA standby mode current
— 5 mA read current
■ Package option
— 48-ball FBGA
— 48-pin TSOP
— 20 mA program/erase current
■ Compatibility with JEDEC standards
■ Flexible sector architecture
— Pinout and software compatible with single-power
supply Flash
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and seven
64 Kbyte sectors (byte mode)
— Superior inadvertent write protection
— One 8 Kword, two 4 Kword, one 16 Kword, and seven
32 Kword sectors (word mode)
■ Data# Polling and toggle bits
— Supports full chip erase
— Provides a software method of detecting program or
erase operation completion
— 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
■ Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting program or
erase cycle completion
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
■ 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
■ Unlock Bypass Program Command
— Reduces overall programming time when issuing
multiple program command sequences
■ Hardware reset pin (RESET#)
— Hardware method to reset the device to reading array
data
■ Top or bottom boot block configurations
available
