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
— 1.65 to 2.2 V for read, program, and erase
operations
— Ideal for battery-powered applications
■
Manufactured on 0.32 μm process
technology
■
High performance
— Access times as fast as 100 ns
■
Ultra low power consumption (typical
values at 5 MHz)
— 1 μA Automatic Sleep Mode current
— 1 μA standby mode current
— 5 mA read current
— 20 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 erase cycle
guarantee per sector
■
20-year data retention at 125
°
C
■
Package option
— 48-ball FBGA
— 48-pin TSOP
■
Compatibility with JEDEC standards
— Pinout and software compatible with
single-power 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
