6 / 48 page MC13224V Product Preview, Rev. 1.0 6 Freescale Semiconductor — JTAG debug port — Nexus extended feature debug port • System protection features — Low battery detect — Watchdog timer (COP) — Sleep mode timer • Low external component count — Only antenna needed for single-ended 50- Ω RF interface (balun in package) — Only a single crystal is required for the main oscillator; programmable crystal load capacitors are on-chip — All bypass capacitors in package • Supports single crystal reference clock source (typical 24 MHz crystal with 13 - 26 MHz usable) with on-chip programmable crystal load capacitance or external frequency source. Also provides onboard 2 kHz oscillator for wake-up timing or an optional 32.768 kHz crystal for accurate low power timing. • 2.0V to 3.6V operating voltage with on-chip voltage regulators; down to 1.8V with off-chip regulation • Optional buck converter for better battery life. • -40°C to +105°C temperature range • RoHS-compliant 9.5mm x 9.5mm x 1.2mm 99-pin LGA package 2.3 High Density, Low Component Count, Integrated IEEE 802.15.4 Solution The MC13224V is more than a high performance, low power platform-in-a-package IEEE 802.15.4 solution. Not only are the transceiver (radio) and MCU on an SoC, the packaged solution contains a 128 Kbyte serial FLASH memory, onboard bypass capacitors for critical nodes, and RF components that present a single-ended 50- Ω interface for an external antenna. The radio is a full differential design with an on-chip transmit/receive (TX/RX) switch, and the PiP also has an onboard balun for differential to singled-ended conversion. On-chip RF matching is also provided to present the proper impedance to the antenna. To further simplify the application, single crystal operation (optimized for 24 MHz) is supported for full radio and MCU operation. If the default 24 MHz crystal is not used, the device supports 13-26 MHz crystals also. The load capacitance to the crystal oscillator is supplied on-chip to eliminate the need for the otherwise required external capacitors. 2.4 Integrated IEEE 802.15.4 Transceiver (Radio and Modem) The MC13224V IEEE 802.15.4 fully-compliant transceiver provides a complete 2.4 GHz radio with 250 kbps Offset-Quadrature Phase Shift Keying (O-QPSK) data in 5.0 MHz channels and full spread-spectrum encode and decode. The modem supports transmit, receive, clear channel assessment (CCA), Energy Detect (ED), and Link Quality Indication (LQI) as required by the 802.15.4 Standard. |
