XE8806A SEMTECH [Semtech Corporation], XE8806A Datasheet - Page 10

• Manufacturer Part Number: XE8806A
• Description: Ultra Low-Power Low-Voltage
• Manufacturer: SEMTECH [Semtech Corporation]

Table 1-2 gives a more detailed pin map for the different pins in the different packages. It also indicates the
possible I/O configuration of these pins. The indications in blue bold are the configuration at start-up. Please note
that in the SO-28 and SO-24 package several functions are routed to the same package pins. These pins are
indicated in red italic. The pins RFIF(3:0) are the I/O pins of the RF interface, the CNTx pins are possible counter
inputs, PWMx are possible PWM outputs, the CMPD pins are comparator inputs.
