MC13234/MC13237
Low Cost SoC Remote Control Platform for the 2.4 GHz IEEE®
802.15.4 Standard
1 Introduction
The MC13234/MC13237 is Freescale’s low cost
System-on-Chip (SoC) solution for the IEEE® 802.15.4
Standard that incorporates a complete, low power, 2.4
GHz radio frequency transceiver with TX/RX switch, an
8-bit HCS08 CPU, and a functional set of MCU
peripherals into a 48-pin LGA package. This product
targets wireless RF remote control and other
cost-sensitive applications ranging from home TV and
entertainment systems to medical and supports all
ZigBee node types. The MC13234/MC13237 is a highly
integrated solution, with very low power consumption.
The MC13234/MC13237 contains an RF transceiver that
is an 802.15.4 Standard 2006 compliant radio that
operates in the 2.4 GHz ISM frequency band. The
transceiver includes a low noise amplifier, 1 mW
nominal output power amplifier (PA), internal voltage
controlled oscillator (VCO), integrated transmit/receive
switch, on-board power supply regulation, 12-bit ADC
and full spread-spectrum encoding and decoding.
The on-chip CPU is based on the Freescale HCS08
family of microcontroller units (MCU). The onboard
