OPERATION METHOD
Set 5 and mm "H"-level before executing instruction. 3 changes to "L" level, then W is enabled
and operates as the sync signal for serial Ho. The Dl data is latched at the rising edge of ttTR. The data is
output from DO at the falling edge oterk.
Execute instruction only when RDY/W status signal is "H" level. However Busy Monitor instruction can
be executed whenever.
Uses only commands which are included in the Instruction Set listed above.
(1) Read
Executing Read instruction reads out the memory data at the specified address and outputs it serially
from DO.
(2) Program
Executing Program instruction automatically starts internal rewriting of the memory data at the
specified address with the input data.
After Program instruction is input, tT; can be set to "H" level ever while the internal rewriting process
is operating.
(3) Chip Erase
Executing Chip Erase instruction automatically Starts internal erasing of the memory data at all
address.
After Chip Erase instruction is input, E can be set to "H" level even while the internal erasing
process is operating.
(4) Busy Monitor
Executing Busy Monitor instruction outputs the RDY/m status signal from DO.
"L" level is output during Program or Chip Erase operation. "H" level is output when Program or
Chip Erase operation is completed.
The RDY/rtis5 status signal is output until E is switched to "H" level.
(5) UW Enable
Executing ENV Enable instruction sets ENV enable mode and enables Program and Chip Erase
instructions.
(6) ENV Disable
Executing E/W Disable instruction sets the E/W disable mode and disables both the Program and Chip
Erase instructions. Once E/W disable mode is set, ENV disable mode is held until ENV Enable
instruction is executed.
CAUTlONS WHEN TURNING THE POWER ON AND OFF
(1) After turning the power on, wait 1ms for warm-up before executing instruction.
(2) After turning the power on, set either the ENV enable mode or ENV disable mode.
(3) If the power supply voltage is lower the approximately 3.5 V, uw Disable instruction is
automatically executed internally.
