GENERAL DESCRIPTION
The Am29F100 is a 1 Mbit, 5.0 Volt-only Flash memory organized as 128 Kbytes of 8 bits each or 64 words of 16 bits each. The 1 Mbit of data is divided into 5 sectors of one 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and one 64 Kbytes, for flexible erase capability. The 8 bits of data will appear on DQ0–DQ7 or 16 bits on DQ0–DQ15. The Am29F100 is offered in 44-pin SO and 48-pin TSOP packages. This device is designed to be programmed in-system with the standard system 5.0 Volt VCC supply. 12.0 Volt VPP is not required for program or erase operations. The device can also be reprogrammed in standard EPROM programmers.
DISTINCTIVE CHARACTERISTICS
■ 5.0 V ± 10% for read and write operations
— Minimizes system level power requirements
■ Compatible with JEDEC-standards
— Pinout and software compatible with
single-power-supply flash
— Superior inadvertent write protection
■ Package options
— 44-pin SO

— Hardware method that disables any combination
of sectors from write or erase operations.
Implemented using standard PROM programming equipment.
■ Embedded Erase Algorithms
— Automatically pre-programs and erases the
chip or any sector
■ Embedded Program Algorithms
— Automatically programs and verifies data at
specified address
■ Data Polling and Toggle Bit feature for detection of program
or erase cycle completion
■ Ready/Busy output (RY/BY)
— Hardware method for detection of program or erase cycle completion
■ Erase Suspend/Resume
— Supports reading data from a sector not being erased
■ Low power consumption
— 20 mA typical active read current for Byte Mode
