128 Megabit (16 M x 8-Bit) CMOS 3.0 Volt-only,
Uniform Sector Flash Memory with VersatileI/O™ Control

General Description
The Am29LV652D is a 128 Mbit, 3.0 Volt (3.0V to 3.6V) single power supply flash memory device. Each Am29LV065D is a 64 Mbit, 3.0 Volt (3.0V to 3.6V) single power supply flash memory device. The device is designed to be programmed in-system with the standard system 3.0 Volt V_CC supply. A 12.0 Volt V_PP is not required for program or erase operations. The Am29LV652D offers access times of 90, 100, and 120 ns and is offered in a 63-ball FBGA package.

Distinctive Characteristics

Architectural Advantages

• Two 64 Megabit (Am29LV065D) in a single 63-ball 11 x 12mm FBGA package (Note: Features will be described for each internal Am29LV065D)
• Two Chip Enable pins
• Two CE# pins to control selection of each internal Am29LV065D devices
• Single power supply operation
• 3.0 to 3.6 Volt read, erase, and program operations
• VersatileI/O™ control
• Device generates data output voltages and tolerates data input voltages as determined by the voltage on the V_IO pin
• Manufactured on 0.23 µm process technology
• Compatible with JEDEC standards
• Except for the additional CE2# pin, the FBGA is pinout and software compatible with single-power supply Flash
• Superior inadvertent write protection

• 63-ball FBGA

Performance Characteristics

• High performance
• Access times as fast as 90 ns
• Program time: 7µs/word typical utilizing Accelerate function
• Minimum 1 million erase cycle guarantee per sector
• 20-year data retention at 125°C
• Reliable operation for the life of the system
• Program and Erase Performance (VHH not applied to the ACC input pin)
• Byte program time: 5 µs typical
• Sector erase time: 1.6 s typical for each 64 Kbyte sector

Software Features

• CFI (Common Flash Interface) compliant
• Provides device-specific information to the system, allowing host software to easily reconfigure for different Flash devices
• Ultra low power consumption (typical values at 3.0V, 5 MHz) for the part
• 9 mA typical active read current
• 26 mA typical erase/program current
• 400 nA typical standby mode current
• Flexible sector architecture
• Two hundred fifty-six 64 Kbyte sectors
• 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
• Data# Polling and toggle bits
• Provides a software method of detecting program or erase operation completion
• Unlock Bypass Mode Program Command
• Reduces overall programming time when issuing multiple program command sequences

Hardware Features

• Sector Protection
• Hardware method of locking a sector, either in-system or using programming equipment, to prevent any program or erase operation within that sector
• Temporary Sector Unprotect allows changing data in protected sectors in-system
• Ready/Busy# output (RY/BY#)
• Hardware method for detecting program or erase cycle completion
• Hardware reset pin (RESET#)
• Hardware method of resetting the internal state machine to the read mode
• ACC pin
• Accelerates programming time for higher throughput during system production
