Am29DL800B Product Overview
8 Megabit (1 M x 8-Bit/512 K x 16-Bit),
CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory
General Description
The Am29DL800B is an 8 Mbit, 3.0 volt-only flash memory device. This device requires only a single 3.0 volt VCC supply to perform read, program, and erase operations. A standard EPROM programmer can also be used to program and erase the device. The device is offered in 44-pin SO, 48-pin TSOP, and 48-ball FBGA packages.
Distinctive Characteristics

- Read-while-erase
- Read-while-program
- Single power supply operation
- Full voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications
- Manufactured on 0.35 µm process technology
- Compatible with 0.5 µm Am29DL800 device
- Flexible sector architecture
- Two 16 Kword, two 8 Kword, four 4 Kword, and fourteen 32 Kword sectors in word mode
- Two 32 Kbyte, two 16 Kbyte, four 8 Kbyte, and fourteen 64 Kbyte sectors in byte mode
- Any combination of sectors can be erased
- Supports full chip erase
- Top or bottom boot block configurations available
- Compatible with JEDEC standards
- Pinout and software compatible with single-power-supply flash standard
- Superior inadvertent write protection

Software Features
- Unlock Bypass Program Command
- Reduces overall programming time when issuing multiple program command sequences
- Data# Polling and Toggle Bits
- Provides a software method of detecting program or erase cycle completion
- Erase Suspend/Erase Resume
- Suspends or resumes erasing sectors to allow reading and programming in other sectors
- No need to suspend if sector is in the other bank

Hardware Features
- Sector protection
- Hardware method of locking a sector to prevent any program or erase operation within that sector
- Sectors can be locked in-system or via programming equipment
- Temporary Sector Unprotect feature allows code changes in previously locked sectors
- Ready/Busy# output (RY/BY#)
- Hardware method for detecting program or erase cycle completion
- Hardware reset pin (RESET#)
- Hardware method of resetting the device to reading array data
