CMOS 5.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
This Data Sheet states AMD’s current technical specifications regarding the Products described herein. This Data
Sheet may be revised by subsequent versions or modifications due to changes in technical specifications.
Single power supply operation
— 5.0 Volt-only operation for read, erase, and
— Minimizes system level requirements
Manufactured on 0.32 µm process technology
— Compatible with 0.5 µm Am29F002 device
High performance
— Access times as fast as 55 ns
Low power consumption (typical values at
5 MHz)
— 1 µA standby mode current
— 20 mA read current
— 30 mA program/erase current
Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
— Supports full chip erase
— Sector Protection features:
Top or bottom boot block configurations available
program operations
three 64 Kbyte sectors
A hardware method of locking a sector to
prevent any program or erase operations within
that sector
Sectors can be locked via programming equipment
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
Embedded Algorithms
— Embedded Erase algorithm automatically
— Embedded Program algorithm automatically
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
— 32-pin PDIP
— 32-pin TSOP
— 32-pin PLCC
Compatibility with JEDEC standards
— Pinout and software compatible with
— Superior inadvertent write protection
Data# Polling and toggle bits
— Provides a software method of detecting
Erase Suspend/Erase Resume
— Suspends an erase operation to read data from,
Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
preprograms and erases the entire chip or any
combination of designated sectors
writes and verifies data at specified addresses
single-power supply Flash
program or erase operation completion
or program data to, a sector that is not being
erased, then resumes the erase operation
array data (not available on Am29F002NB)
