Am29BL162C

16 Megabit (1 M 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 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

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

CFI (Common Flash Interface) compliant

— Provides device-specific information to the

system, allowing host software to easily

reconfigure for different Flash devices

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

Package Option

— 56-pin SSOP
