6 / 50 page MC13224V Technical Data, Rev. 1.2 6 Freescale Semiconductor — 8-pin keyboard interface (KBI) supports up to a 4x4 matrix. Also, provides up to four asynchronous interrupt inputs for wake-up — Two 12-bit analog-to-digital converters (ADCs) share 8 input channels — Four independent 16-bit timers with PWM capability. These can cascade in combinations up to 64-bit operation — Inter-integrated circuit (I2C) interface — Synchronous Serial Interface (SSI) with I2S and SPI capability and FIFO data buffering — Up to 64 programmable I/O shared by peripherals and GPIO • Powerful In-circuit debug and FLASH programming available via on-chip debug ports — 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. • 2.0 V to 3.6 V operating voltage with on-chip voltage regulators. • 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 |
