Components
Microcontroller (U2)
The 8-bit flash-based ATmega 128L/ATmega64L microcontroller contains software for the configuration and
control of the RM2420, AMC and network functions, and the user-defined application software. The
microcontroller utilizes a 32.768KHz crystal for MAC timing and power management, as well as external crystal
operating at 8Hz. A variety of peripherals are routed to headers on the Developer Kit carrier board for
application development. For detail information on the microcontroller, see www.atmel.com
.
When configuring the Ember Studio Debug Reader, enter the following baud rate into the Debug Preference
Window: 100,000. This rate is set by the microcontroller operating frequency.
Radio (U5)
The radio is an RM2420, a true single-chip 2.4GHz IEEE 802.15.4 – compliant and Zigbee-ready radio
frequency transceiver designed for low-power and low-voltage wireless applications. It includes a digital direct
sequence spread-spectrum (DSSS) baseband modem with an effective data rate of 250kbps.
