EEPROM UNIT
1. CIRCUIT DIAGRAM
2. EXPLANATION OF CIRCUIT
In contrast with mask ROM, EEPROM which enable WRITE/READ by program, memorize data even
during POWER is OFF.
• EEPROM PIN FUNCTION
EEPROM stores the selected contents in MEMORY course and LOAD SENSING data.
If you press MEMORY button, MICOM read the contents in MEMORY course and L.E.D displays the
selected contents in MEMORY course.
3. CAUTION FOR A/S
1. When the selected contents of MEMORY course in EEPROM can not memorize, EEPROM is
defective.
PIN NAME FUNCTION
Chip selector
CS Chip is enabled when CS is at ‘L’ level.
Set CS to ‘H’ level before executing instruction.
Clock input
CLK The DI data is latched at the rising edge of CLK.
The data is out from DO at the falling edge of CLK.
CLK is enable when CS is at ‘L’ level.
DI Serial data input
The address, command and data input pin.
DO Serial data output
The data output pin
Organization select
ORG The 16-bit organization is selected when ORG is ‘H’ level.
The 8-bit organization is selected when ORG is ‘L’ level.
Status output
RDY/BUSY ‘L’ level is output during program or chip eraise operation.
‘H’ level is output when program or chip eraise operation is completed.
