GENERAL DESCRIPTION
The Am29BL802C is an 8 Mbit, 3.0 Volt-only burst mode Flash memory devices organized as 524, 288 words. The device is offered in a 56-pin SSOP package. These devices are designed to be programmed in-system with the standard system 3.0-volt VCC supply. A 12.0-volt VPP or 5.0 VCC is not required for program or erase operations. The device can also be programmed in standard EPROM programmers.
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 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
