　　The MC1323x family is Freescale’s low cost System-on-Chip (SoC) platform 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 family of products is targeted for wireless RF remote control and other cost-sensitive applications ranging from home TV and entertainment systems such as ZigBee BeeStack Consumer (RF4CE) to low cost, low power, IEEE 802.15.4 and ZigBee end nodes. The MC1323x is a highly integrated solution, with very low power consumption.

　　The MC1323x contains an RF transceiver which 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, 1mW nominal output power power amplifier (PA), internal voltage controlled oscillator (VCO), integrated transmit/receive switch, on-board power supply regulation, and full spread-spectrum encoding and decoding.

　　The on-chip CPU is based on the Freescale HCS08 family of Microcontroller Units (MCU) and has 82 kilobyte (KB) of FLASH memory and 5KB of RAM. The onboard MCU peripheral set has been defined to support the targeted applications. A dedicated DMA block transfers packet data between RAM and the transceiver to off-load the CPU and allow higher efficiency and increased performance.
