GENERAL DESCRIPTION
The Am29F032B is a 32 Mbit, 5.0 volt-only Flash memory organized as 4,194,304 bytes of 8 bits each. The 4 Mbytes of data are divided into 64 sectors of 64 Kbytes each for flexible erase capability. The 8 bits of data appear on DQ0–DQ7. The Am29F032B is offered in 40-pin TSOP and 44-pin SO packages. The Am29F032B is manufactured using AMD’s 0.32 µm process technology. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0 volt VPP is not required for program or erase operations. The device can also be programmed in standard EPROM programmers.
DISTINCTIVE CHARACTERISTICS
◾ 5.0 V ± 10%, single power supply operation
— Minimizes system level power requirements
◾ Manufactured on 0.32 µm process technology
◾ High performance
— Access times as fast as 70 ns
◾ Low power consumption
— 30 mA typical active read current
— 30 mA typical program/erase current
— <1 µA typical standby current (standard access
time to active mode)
◾ Flexible sector architecture
— 64 uniform sectors of 64 Kbytes each
— Any combination of sectors can be erased.
— Supports full chip erase
— Group sector protection:
— A hardware method of locking sector groups to
prevent any program or erase operations within
that sector group
— Temporary Sector Group Unprotect allows code
changes in previously locked sectors
◾ 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 bytes at specified addresses
◾ Minimum 1,000,000 write/erase cycles
guaranteed
◾ 20-year data retention at 125°C
— Reliable operation for the life of the system
◾ Package options
— 40-pin TSOP
— 44-pin SO
