AM29F016D-90E4I

GENERAL DESCRIPTION

The Am29F016D is a 16 Mbit, 5.0 volt-only Flash memory organized as 2,097,152 bytes. The 8 bits of data appear on DQ0–DQ7. The Am29F016D is offered in 48-pin TSOP, 40-pin TSOP, and 44-pin SO packages. The device is also available in Known Good Die (KGD) form. For more information, refer to publication number 21551. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0 volt VPP is not required for program or erase operations. The device can also be programmed in standard EPROM programmers.

DISTINCTIVE CHARACTERISTICS

■ 5.0 V ± 10%, single power supply operation
— Minimizes system level power requirements
■ Manufactured on 0.23 µm process technology
— Compatible with 0.5 µm Am29F016 and 0.32 µm Am29F016B devices
■ 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)
■ Flexible sector architecture
— 32 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
■ 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 bytes at specified addresses
■ Unlock Bypass Program Command
— Reduces overall programming time when issuing multiple program command sequences
■ 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
■ Package options
— 48-pin and 40-pin TSOP
— 44-pin SO
— Known Good Die (KGD) (see publication number 21551)
■ Compatible with JEDEC standards
— Pinout and software compatible with single-power-supply Flash standard
— Superior inadvertent write protection
■ Data# Polling and toggle bits
— Provides a software method of detecting program or erase cycle completion
■ Ready/Busy# output (RY/BY#)
— Provides a hardware method for 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 reset pin (RESET#)
— Resets internal state machine to the read mode
