COMMAND DEFINITIONS
The operations of the EN29LV400A are selected by one or more commands written into the
command register to perform Read/Reset Memory, Read ID, Read Sector Protection, Program,
Sector Erase, Chip Erase, Erase Suspend and Erase Resume. Commands are made up of data
sequences written at specific addresses via the command register. The sequences for the
specified operation are defined in the Command Definitions table (Table 5). Incorrect addresses,
incorrect data values or improper sequences will reset the device to Read Mode.

Address and Data values indicated in hex
RA = Read Address: address of the memory location to be read. This is a read cycle.
RD = Read Data: data read from location RA during Read operation. This is a read cycle.
PA = Program Address: address of the memory location to be programmed. X = Don’t-Care
PD = Program Data: data to be programmed at location PA
SA = Sector Address: address of the Sector to be erased or verified. Address bits A17-A12 uniquely select any Sector.
Reading Array Data
The device is automatically set to reading array data after power up. No commands are required to
retrieve data. The device is also ready to read array data after completing an Embedded Program
or Embedded Erase algorithm.
Following an Erase Suspend command, Erase Suspend mode is entered. The system can read
array data using the standard read timings, with the only difference in that if it reads at an address
within erase suspended sectors, the device outputs status data. After completing a programming
