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 protection

PACKAGE OPTIONS

■ 48-pin TSOP1

PERFORMANCE 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 typical

SOFTWARE 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 completion

HARDWARE FEATURES

■ Ready/Busy# pin (RY/BY#)

   — Provides a hardware method of detecting program or erase cycle completion

■ Hardware reset pin (RESET#)
