描述 Description

GENERAL DESCRIPTION
The AS29LV016 is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152 bytes or 1,048,576 words. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed in-system with the standard system 3.0 volt VCC supply. A 12.0 V VPP or 5.0 VCC are not required for write or erase operations. The device can also be programmed in standard EPROM programmers.DISTINCTIVE CHARACTERISTICS
■ Commercial Off The Shelf, up-screened device
■ Single power supply operation
?? — Full voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications
■ Manufactured on 200nm process technology
■ Flexible sector architecture
?? — One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and thirty-one 64 Kbyte sectors (byte mode)
?? — One 8 Kword, two 4 Kword, one 16 Kword, and thirty-one 32 Kword sectors (word mode)
■ Sector Protection features
?? — A hardware method of locking a sector to prevent any program or erase operations within that sector
?? — Sectors can be locked in-system or via programming equipment
?? — Temporary Sector Unprotect feature allows code changes in previously locked sectors
■ Unlock Bypass Program Command
?? — Reduces overall programming time when issuing multiple program command sequences
■ Top or bottom boot block configurations available
■ Compatibility with JEDEC standards
?? — Pinout and software compatible with single-power supply Flash
?? — Superior inadvertent write protectionPACKAGE OPTIONS
■ 48-pin TSOP1PERFORMANCE CHARACTERISTICS
■ High performance
?? — Access times as fast as 70 ns @ Enhanced Temp [/ET]
?? — Extended temp range available [/XT] (-55°C to +125°C)
■ Ultra low power consumption (typical values at 5 MHz)
?? — 200 nA Automatic Sleep mode current
?? — 200 nA standby mode current
?? — 9 mA read current
?? — 20 mA program/erase current
■ Cycling endurance: 1,000,000 cycles per sector typical
■ Data retention: 20 years typicalSOFTWARE FEATURES
■ CFI (Common Flash Interface) compliant
?? — Provides device-specific information to the system, allowing host software to easily reconfigure for different Flash devices
■ 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 completionHARDWARE FEATURES
■ Ready/Busy# pin (RY/BY#)
?? — Provides a hardware method of detecting program or erase cycle completion
■ Hardware reset pin (RESET#)
