AC4486 Specifications
4.4 EEPROM C
The configuration commands allow the Host to modify the operation of the transceiver. If the
transceiver is in Command mode (Command/Data pin (Pin 17) is pulled logic Low or the Enter AT
Command mode and AT Enter Configuration mode commands have been sent to the transceiver), the
transceiver will interpret incoming Host data as Command Data. The Host can then read and write
parameters using the various configuration commands listed below. To exit Configuration Mode, the
Host must perform a hardware or power-on reset or issue an Exit Command Mode command to the
transceiver. While in Configuration Mode, the RF circuitry will be disabled.
4.4.1 EEPROM Byte Read
Upon receiving this command, a transceiver will respond with the desired data from the address
requested by the Host.
Host Command:
Transceiver Response:
4.4.2 EEPROM Byte Write
Upon receiving this command, a transceiver will write the data byte to the address specified but will not
echo it back to the Host until the EEPROM write cycle is complete. The write can take as long as
10ms to complete. Following the write cycle, a transceiver will transmit the data byte to the Host.
Multiple byte EEPROM writes are allowed up to a length of 128 bytes. An EEPROM boundary exists
between addresses 7Fh and 80h. No single EEPROM write command shall write to addresses on
both sides of that EEPROM boundary.
Host Command:
Transceiver Response:

Byte 1 = C0h
Byte 2 = Address
Byte 3 = Length (01…FFh = 1…255 bytes; 00h = 256 bytes)
Byte 1 = C0h
Byte 2 = Address
Byte 3 = Length
Byte 4…n = Data at requested address(s)
Byte 1 = C1h
Byte 2 = Address
Byte 3 = Length (01 – 80h)
Byte 4…n = Data to store at Address
Byte 1 = C1h
Byte 2 = Address
Byte 3 = Length (01 – 80h)
Byte 4 = Last data byte written by this command
