16 Megabit (1 M x 16-Bit),
CMOS 3.0 Volt-only Burst Mode Flash Memory

General Description
The Am29BL162C is a 16 Mbit, 3.0 Volt-only Burst mode Flash memory. These devices are designed to be programmed in-system with the standard system 3.0 Volt V_CC supply. A 12.0 Volt V_PP or 5.0 V_CC is not required for program or erase operations. The device can also be programmed in standard EPROM programmers. The device offers access times of 65, 70, 90, and 120 ns, allowing high speed microprocessors to operate without wait states The device is offered in a 56-pin SSOP package.

Distinctive Characteristics

Architectural Advantages

• 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
• Alterable Burst length via BAA# pin
• 5.0V-tolerant data, address, and control signals
• Compatible with JEDEC standards
• Pinout and software compatible with single power supply Flash
• Superior inadvertent write protection
• Backward-compatible with AMD Am29LVxxx and Am29Fxxx Flash memories: powers up in asynchronous mode for system boot, but can immediately be placed into Burst mode

• 56-pin SSOP

Performance Characteristics

• 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
• 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
• Minimum 100,000 erase cycle guarantee per sector
• 20-year data retention

Software Features

• Unlock Bypass Program Command
• Reduces overall programming time when issuing multiple program command sequences
• CFI (Common Flash Interface) compliant
• Provides device-specific information to the system, allowing host software to easily reconfigure for different Flash devices
• Data# Polling and toggle bits
• Provides a software method of detecting program or erase operation 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 Features

• Sector protection
• Implemented using in-system or via programming equipment
• Temporary Sector Unprotect feature allows code changes in previously locked sectors
• Ready/Busy# pin (RY/BY#)
• Provides a hardware method of detecting program or erase cycle completion
• Hardware reset pin (RESET#)
• Hardware method to reset the device for reading array data
