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 0.23 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
●■ Compatible with JEDEC standards
● — Pinout and software compatible with single power supply Flash
● — Superior inadvertent write protection
●■ 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 data at specified addresses
●■ 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
●■ Unlock Bypass Program command
● — Reduces overall programming time when issuing multiple program command sequences
●■ Ready/Busy# pin (RY/BY#)
● — Provides a hardware method of detecting program or erase cycle completion
●■ Hardware reset pin (RESET#)
● — Hardware method to reset the device for reading array data
●■ WP# input pin
● — At VIL, protects the 16 Kbyte boot sector from erasure regardless of sector protect/unprotect status
● — At VIH, allows removal of boot sector protection
●■ Program and Erase Performance
● — Sector erase time: 1 s typical for each 64 Kbyte sector
● — Byte program time: 7 µs typical
