STL 2.4G transceiver moduleTechnical ManualGeneral-----------The modules is a low power radio frequency module operating within the ISM 2.4 GHz frequency band. The radio transceiver is compatible with IEEE.802.15.4 standard with hardware acceleration for both the IEEE 802.15.4 MAC and AES security.. It also incoproates a 32-bit ARM7 core based MCU, 128 Kbyte FLASH memory and 96 Kbyte RAM. It is intended for use as a short range radio module for embedded applications.Features Summary- IEEE 802.15.4 standard compliant on-chip transceiver/modem- 2.4 GHz ISM Band operation- Programmable transmitter output power (-30 dBm to +4 dBm typical)- World-class receiver sensitivity-96 dBm typical receiver sensitivity using DCD mode (<1% PER, 20-byte packets)-100 dBm typical receiver sensitivity using NCD mode (<1% PER, 20-byte packets) Hardware acceleration for IEEE 802.15.4 applications MAC accelerator (sequencer and DMA interface) Advanced encryption/decryption hardware engine (AES 128-bit)Supports standard IEEE 802.15.4 signaling with 250 kbps data rate32-bit ARM7TDMI-S CPU core with programmable performance up to 26 MHz (24 MHz typical)Extensive on-board memory resources— 128 Kbyte serial FLASH memory (will be mirrored into RAM)— 96 Kbyte SRAM— 80 Kbyte ROMbuilt in voltage regulatorUART and SPI interface for control and data interfaceGPIOs for general controlRF Shield can to reduce interference3.3V DC supplyCONFIDENTIAL
Block DiagramFig. 1 Block DiagramRF OperationThe RF radio interface provides for low cost and the high density as shown in Figure 2. The transceiver is a zero IF radio without intermediate frequency (IF)stage. An onboard balun along with a TX/RX switch allows direct connection to a single-ended 50-Ω antenna. The integrated PA provides programmable output power typically from -30 dBm to +4 dBm, and the RX LNA provides -96 dBm sensitivity. In addition, separate complementary PA outputs allow use of an external PA and/or an external LNA for extended range applications. The device also has onboard bypass capacitors and crystal load capacitors for the smallest footprint in the industry. All components are integrated into the package except the crystal and antenna.Figure 2. MC13224V RF Radio InterfaceRefer to Freescale MC13224V datasheet for details.
