8 Megabit (1 M x 8-Bit),
CMOS 5.0 Volt-only, Uniform Sector Flash Memory

General Description
The Am29F080B is an 8 Mbit, 5.0 Volt-only Flash Memory. This device is designed to be programmed in-system with the standard system 5.0 Volt V_CC supply. A 12.0 Volt V_PP is not required for program or erase operations. The Am29F080B is offered in 40-pin TSOP and 44-pin SO packages.

Distinctive Characteristics

Architectural Advantages

• 5.0 V ± 10% single power supply operation
• Minimizes system level power requirements
• Manufactured on 0.32 µm process technology
• Compatible with 0.5 µm Am29F080 device
• Flexible sector architecture
• 16 uniform sectors of 64 Kbytes each
• Any combination of sectors can be erased
• Supports full chip erase
• Group sector protection:
  - A hardware method of locking sector groups to prevent any program or erase operations within that sector group
  - Temporary Sector Group Unprotect allows code changes in previously locked sectors
• Compatible with JEDEC standards
• Pinout and software compatible with single-power-supply Flash standard
• Superior protection against inadvertent write
• Command sequence optimized for mass storage
• Specific addresses not required for unlock cycles

• 40-pin TSOP
• 44-pin SO

Performance Characteristics

• High performance
• Access times as fast as 70 ns
• Low power consumption
• 25 mA typical active read current
• 30 mA typical program/erase current
• 1 µA typical standby current (standard access time to active mode)
• Minimum 1,000,000 program/erase cycles per sector guaranteed
• 20-year data retention at 125°C
• Reliable operation for the life of the system

Software Features

• Data# Polling and toggle bits
• Provides a software method of detecting program or erase cycle completion
• Erase Suspend/Erase Resume
• Suspends a sector erase operation to read data from, or program data to, a non-erasing sector, then resumes the erase operation

Hardware Features

• Ready/Busy# output (RY/BY#)
• Provides a hardware method for detecting program or erase cycle completion
• Hardware reset pin (RESET#)
• Resets internal state machine to the read mode
