2.4 Interface IC RFW-D100
The RFW-D100 is a complimentary IC to the RFW-102 module. It
provides an MCU with a parallel interface to the RFW-102 transceiver
module and other features that enable implementing a protocol suitable
for wireless communication with a small burden on the MCU.
In HID application, the MCU is in charge of the MAC layer protocol. The
RFW-D100 is used to reduce the real-time demands of the MCU
handling the MAC protocol. It converts the fast serial input to 8-bit words,
which are much easier for 8-bit MCUs to work with. Also, it buffers the
input through a 16-byte FIFO, giving the MCU access the RFW-D100
efficiently. Instead of reading one byte per interrupt, the MCU can read
up to 16 bytes in each interrupt.
Below are the features of the RFW-D100 interface IC:
Provides parallel interface with the RFW102 modem
Serial to parallel conversion of the RFW102 interface
Input FIFO (RX_FIFO)
Output FIFO (TX_FIFO)
Preamble Correlation
Packet Address Filter
CRC calculation
Watchdog Timer driven by internal RC oscillator
Power saving mode: Idle, Power-down.
Receiver signal strength indication (RSSI)
