Legend:
X=Don't care
RA=Address of the memory location to be read.
RD=Data read from location RA during read operation.
PA=Address of the memory location to be programmed.
Addresses are latched on the falling edge of the WE or CE
pulse.
Notes:
1. See Table 1 for descriptions of bus operations.
2. All values are in hexadecimal.
3. Except when reading array or Automatic Select data, all bus cycles are write operation.
4. The Reset command is required to return to the read mode when the device is in the Automatic Select mode or if Q5 goes
high.
5. The fourth cycle of the Automatic Select command sequence is a read cycle.
6. The data is 99h for factory locked and 19h for not factory locked.
7. The data is 00h for an unprotected sector/sector block and 01h for a protected sector/sector block. In the third cycle of the
command sequence, address bit A20=0 to verify sectors 0~31, A20=1 to verify sectors 32~70 for Top Boot device.
8. Command is valid when device is ready to read array data or when device is in Automatic Select mode.
9. The system may read and program functions in non-erasing sectors, or enter the Automatic Select mode, when in the erase
Suspend mode. The Erase Suspend command is valid only during a sector erase operation.
10.The Erase Resume command is valid only during the Erase Suspend mode.
TABLE 3. MX29LV320T/B COMMAND DEFINITIONS
PD=Data to be programmed at location PA. Data is latched
on the rising edge of WE or CE pulse.
SA=Address of the sector to be erased or verified. Address
bits A20-A12 uniquely select any sector.
ID=22A7h(Top), 22A8h(Bottom)
