GENERAL DESCRIPTION
The Am29BL802C in Known Good Die (KGD) form is an 8 Mbit, 3.0 volt-only Flash memory. AMD defines KGD as standard product in die form, tested for functionality and speed. AMD KGD products have the same reliability and quality as AMD products in packaged form.
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
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, 25 mA @ 40 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
