GENERAL DESCRIPTION

The Am29F160D is a 16 Mbit, 5.0 Volt-only Flash memory device organized as 2,097,152 bytes or 1,048,576 words. Data appears on DQ0-DQ7 or DQ0-DQ15 depending on the data width selected. The 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 Volt single power supply operation

— Minimizes system-level power requirements

■ High performance

— Access times as fast as 70 ns

■ Manufactured on 0.25 µm process technology

■ CFI (Common Flash Interface) compliant

— Provides device-specific information to the

system, allowing host software to easily

reconfigure for different Flash devices

■ Ultra low power consumption (typical values at 5 MHz)

— 15 mA typical active read current

— 35 mA typical erase/program current

— 300 nA typical standby mode current

■ 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)

— Supports full chip erase

— Sector Protection features:

— Hardware method of locking a sector to prevent

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

■ Top boot or bottom boot configurations available

■ Minimum 1,000,000 write cycle guarantee per sector

■ 20-year data retention at 125°C

— Reliable operation for the life of the system

■ Package options

— 48-pin TSOP (Continue ...)
