• Manufacturer Part Number: A29L160TG-120
• Description: 2M X 8 Bit / 1M X 16 Bit CMOS 3.0 Volt-only, Boot Sector Flash Memory
• Manufacturer: AMICC [AMIC Technology]

Common Flash Memory Interface (CFI)
The Common Flash Interface (CFI) specification outlines
device and host system software interrogation handshake,
which allows specific vendor-specified software algorithms to
be used for entire families of devices. Software support can
then be device-independent, JEDEC ID-independent, and
forward- and backward-compatible for the specified flash
device families. Flash vendors can standardize their existing
interface for long-term compatibility.
This device enters the CFI Query mode when the system
writes the CFI Query command, 98h, to address 55h in word
mode (or address AAh in byte mode), any time the device is

ready to read array data. The system can read CFI
information at the addresses given in Table 5-8. In word
mode, the upper address bits (A7-MSB) must be all zeros. To
terminate reading CFI data, the system must write the reset
command.
The system can also write the CFI query command when the
device is in the autoselect mode. The device enters the CFI
query mode, and the system can read CFI data at the
addresses given in Table 5-8. The system must write the
reset command to return the device to the autoselect mode
