P89C738; P89C739
Table 23 Command denitions
Notes
1. X = don’t care.
2. IA = identifier address.
3. ID = data read from location IA during device identification.
4. PA = address of memory location to be programmed.
5. PD = data to be programmed at location.
Table 24 P89C738 bus operations
Notes
1. VPPH is the programming voltage specified for the device.
2. Manufacturer and device codes are accessed via a command register write sequence. Refer to Table 23. All other
addresses are LOW.
3. Data out means that the data is read out from the microcontroller. Data in means that the data is send into the
microcontroller from outside.
4. Read operation with VPP =VPPH may access array data (if write command is preceded) or Silicon-ID codes.
5. With VPP at high voltage, the standby current equals IDD +IPP (standby).
6. X can be VIL or VIH.
