µPD75048

5. EEPROM

The µPD75048 contains the 1024-word x 4-bit EEPROM (Electrically Erasable PROM).

The EEPROM of the µPD75048 has the following characteristics.

• The EEPROM can retain its contents even if the power is turned off.

• In the same manner as the static RAM, data can be manipulated (auto-erase/write/read) in 4-bit

or 8-bit units by using a memory manipulation instruction

• The contens of EEPROM are automatically erased or written by hardware, so that the overhead

of the software is alleviated.

• Write time .... 10 ms.

• Number of write operation100,000 times (guaranteed).

• Write operation can be controlled by interrupt.

• When write operation is completed an interrupt occurs.

• When overwrite is executed. (Write operation is executed during write operation)

• Whether or not the EEPROM is possible to be written can be checked by individually checking the

write status flag.
