GENERAL DESCRIPTION

The Am29F017D 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 Am29F017D is offered in a 40-pin or 48-pin TSOP package. This device is designed to be programmed in-system with the standard system 5.0 volt VCCsupply. A 12.0 volt VPPis not required for program or erase operations. The device can also be programmed in standard EPROM programmers.

This device is manufactured using AMD’s 0.23 µm process technology, and offers all the features and benefits of the 0.32 µm Am29F017B and the 0.5 µm Am29F016C.

DISTINCTIVE CHARACTERISTICS

„Optimized for memory card applications

— Backwards-compatible with Am29F016C and Am29F017B

„5.0 V ±10, single power supply operation

— Minimizes system level power requirements „Manufactured on 0.23 µm process technology

„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

— 40-pin TSOP

— 48-pin TSOP

„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
