This document describes the development system of MICRFXXX series radio frequency transceivers, including system composition, input and output, DIP switch settings, getting started, RF test modes, 2-way Link Test Mode, Byte Transfer Modes, Simple Byte Transfer Mode, Advanced Byte Transfer Mode, PC program, firmware upgrade, etc.
The Micrel development system provides a hands‑on platform for evaluating the MICRF505, MICRF506, MICRF600, MICRF610 and MICRF620 transceivers. The board includes a PIC18LF4320 microcontroller, SMA antenna connector, RS‑232 or logic‑level serial interface, and a set of LEDs and DIP switches to select operating modes.
The manual describes board inputs/outputs, how to configure DIP switches for RF test, byte‑transfer and 2‑way link modes, and details the PC‑side RF TestBench software. Firmware can be upgraded via the on‑board ICSP socket using a Microchip MPLAB ICD2 programmer.
| Frequency band (MICRF505) | 915 MHz |
|---|---|
| Pre‑programmed frequencies (MICRF505) | 25 frequencies |
| Power supply | 6‑9 V DC |
| Antenna connector | SMA external antenna |
| Microcontroller | PIC18LF4320 |
| LEDs | 1 power, 1 RF, 4 status LEDs |
| DIP switches | 4 switches for mode selection |
| Serial interface | RS‑232 or logic‑level, 9600‑8‑N‑1 |
| Buffer depth | 64 bytes for RX and TX |
The board operates from a 6 V to 9 V DC supply.
There is one power‑on LED, one RF‑powered LED, and four status/control LEDs.
The four DIP switches select the board’s mode of operation, such as RF test, byte‑transfer or link‑test modes.
