200 mA Programmable IC Chips AM29BL802CB-65RZE USB Flash MCU Famil

Am29BL802C

8 Megabit (512 K x 16-Bit) CMOS 3.0

Volt-only Burst Mode Flash Memory

DISTINCTIVE CHARACTERISTICS

■ 32 words sequential with wrap around (linear 32), bottom boot

■ One 8 Kword, two 4 Kword, one 48 Kword, three 64 Kword, and two 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 Burst access times as fast as 17 ns at industrial temperature range (18 ns at extended temperature range) Initial/random access times as fast as 65 ns

■ Alterable burst length via BAA# pin

■ Power dissipation (typical) — Burst Mode Read: 15 mA @ 25 MHz, 20 mA @ 33 MHz, 25 mA @ 40 MHz — Program/Erase: 20 mA — Standby mode, CMOS: 3 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 Program algorithm automatically writes and verifies data at specified addresses

■ Minimum 100,000 erase cycle guarantee per sector

■ 20-year data retention ■ Compatibility with JEDEC standards

— Pinout and software compatible with singlepower 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

■ Package Option — 56-pin SSOP
