MICREL User Manual for Development System MICRF505 MICRF506 MICRF600 MICRF610 MICRF620 FW v. 4
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.
