AM29F040B-70JD Allgemeine Beschreibung

GENERAL DESCRIPTIONThe Am29F040B is a 4 Mbit, 5.0 volt-only Flash memory organized as 524,288 Kbytes of 8 bits each. The 512 Kbytes of data are divided into eight sectors of 64 Kbytes each for flexible erase capability. The 8 bits of data appear on DQ0–DQ7. The Am29F040B is offered in 32-pin PLCC, TSOP, and PDIP packages. 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 write or erase operations. The device can also be programmed in standard EPROM programmers.DISTINCTIVE CHARACTERISTICS• 5.0 V ± 10% for read and write operations — Minimizes system level power requirements• Manufactured on 0.32 µm process technology — Compatible with 0.5 µm Am29F040 device• High performance — Access times as fast as 55 ns• Low power consumption — 20 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 — 8 uniform sectors of 64 Kbytes each — Any combination of sectors can be erased — Supports full chip erase — Sector protection: A hardware method of locking sectors to prevent any program or erase operations within that sector• 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• 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 — 32-pin PLCC, TSOP, or PDIP• 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• 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
