Advanced Micro Devices 

Am29F004B

4 Megabit (512 K x 8-Bit)

CMOS 5.0 Volt-only Boot Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

„ 5.0 Volt single power supply operation

— Minimizes system-level power requirements

„ High performance

— Access times as fast as 70 ns

„ Manufactured on 0.32 µm process technology

„ Ultra low power consumption (typical values at

5 MHz)

— 20 mA typical active read current

— 30 mA typical program/erase current

— 1 µA typical standby mode current

„ Flexible sector architecture

— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and

seven 64 Kbyte sectors

— 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

„ Top or bottom boot block configurations available

„ Minimum 1,000,000 write cycle guarantee per

sector

„ Package option

— 32-pin PLCC

„ Compatible with JEDEC standards

— Pinout and software compatible with single-

power supply Flash

— Superior inadvertent write protection

„ 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

„ 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

„ Data# Polling and toggle bits

— Provides a software method of detecting

program or erase operation completion

„ 20-year data retention at 125°C
