2 / 19 page SUPPLEMENT Publication# 23783 Rev: A Amendment/+4 Issue Date: April 29, 2003 Am29BL162C Known Good Die 16 Megabit (1 M x 16-Bit) CMOS 3.0 Volt-only, Burst-Mode, Boot Sector Flash Memory—Die Revision 1 DISTINCTIVE CHARACTERISTICS ■ 32 words sequential with wrap around (linear 32), bottom boot ■ One 8 Kword, two 4 Kword, one 112 Kword, and seven 128 Kword sectors ■ Single power supply operation — Regulated voltage range: 3.0 to 3.6 volt read and write operations and for compatibility with high performance 3.3 volt microprocessors ■ Read access times 22 ns burst access (at extended temperature range) 80 ns initial/random access ■ Alterable burst length via BAA# pin ■ Power dissipation (typical) — Burst Mode Read: 15 mA @ 25 MHz, 20 mA @ 33 MHz — Program/Erase: 20 mA — Standby mode, CMOS: 22 µA ■ 5 V-tolerant data, address, and control signals ■ Sector Protection — Implemented using in-system or via programming equipment — Temporary Sector Unprotect feature allows code changes in previously locked sectors ■ Unlock Bypass Program Command — Reduces overall programming time when issuing multiple program command sequences ■ 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 ■ Minimum 100,000 erase cycle guarantee per sector ■ 20-year data retention at 125 °C ■ Compatibility with JEDEC standards — Pinout and software compatible with single- power supply Flash — Superior inadvertent write protection — Backward-compatible with AMD Am29LV and Am29F flash memories: powers up in asynchronous mode for system boot, but can immediately be placed into burst mode ■ Data# Polling and toggle bits — Provides a software method of detecting program or erase operation completion ■ Ready/Busy# pin (RY/BY#) — Provides a hardware method of detecting program or erase cycle completion ■ 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 ■ Hardware reset pin (RESET#) — Hardware method to reset the device for reading array data ■ Tested to datasheet specifications at temperature ■ Quality and reliability levels equivalent to standard packaged components |
