• Manufacturer Part Number: MX29LV320ML
• Description: 32M-BIT SINGLE VOLTAGE 3V ONLY UNIFORM SECTOR FLASH MEMORY
• Manufacturer: Macronix International

WRITE OPERATION STATUS
The device provides several bits to determine the status
of a write operation: Q2, Q3, Q5, Q6, Q7, and RY/BY#.
Table 5 and the following subsections describe the func-
tions of these bits. Q7, RY/BY#, and Q6 each offer a
method for determining whether a program or erase op-
eration is complete or in progress. These three bits are
discussed first.
Notes:
1. Q5 switches to "1" when an Word/Byte Program, Erase, or Write-to-Buffer operation has exceeded the maximum
2. Q7 and Q2 require a valid address when reading status information. Refer to the appropriate subsection for further
3. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location.
4. Q1 switches to "1" when the device has aborted the write-to-buffer operation.
