Am29BL802C Known Good Die

8 Megabit (512 K x 16-Bit)

CMOS 3.0 Volt-only, Burst-mode, Boot Sector Flash Memory—Die Revision 1

DISTINCTIVE CHARACTERISTICS

s 32 words sequential with wrap around (linear

32), bottom boot

s One 8 Kword, two 4 Kword, one 48 Kword, three

64 Kword, and two 128 Kword sectors

s 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

s Read access times

22 ns burst access at

extended temperature range

80 ns initial/random access

s Alterable burst length via BAA# pin

s 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: 22 µA

s 5 V-tolerant data, address, and control signals

s Sector Protection

— Implemented using in-system or via

programming equipment

— Temporary Sector Unprotect feature allows code

changes in previously locked sectors

s Unlock Bypass Program Command

— Reduces overall programming time when issuing

multiple program command sequences

s 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

s Minimum 100,000 erase cycle guarantee

per sector

s 20-year data retention at 125

°C

s 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

s Data# Polling and toggle bits

— Provides a software method of detecting program

or erase operation completion

s Ready/Busy# pin (RY/BY#)

— Provides a hardware method of detecting

program or erase cycle completion

s 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

s Hardware reset pin (RESET#)

— Hardware method to reset the device for reading

array data

s Tested to datasheet specifications at

temperature

s Quality and reliability levels equivalent to

standard packaged components
