Section 17 EEPROM
17.4
17.4.1
This LSI has a multi-chip structure with two internal chips of F-ZTAT™ HD64F3664 and 512-
byte EEPROM.
The EEPROM interface is the I
communication with the external devices connected to the I
17.4.2
The I
formats specific for the EEPROM are the following two.
1. The EEPROM address is configured of two bytes, the write data is transferred in the order of
2. The write data is transmitted from the MSB side.
The bus format and bus timing of the EEPROM are shown in figure 17.2.
