Chapter 1 MC9S12Q Device Overview (MC9S12Q128-Family)
• Memory options:
— 32Kbyte ROM or Flash EEPROM (erasable in 512-byte sectors)
64K, 96K, or 128Kbyte ROM or Flash EEPROM (erasable in 1024-byte sectors)
— 1K, 2K, 3K or 4K Byte RAM
• Analog-to-digital converters:
— One 8-channel module with 10-bit resolution
— External conversion trigger capability
— One 1M bit per second, CAN 2.0 A, B software compatible module
— Five receive and three transmit buffers
— Flexible identifier filter programmable as 2 x 32 bit, 4 x 16 bit, or 8 x 8 bit
— Four separate interrupt channels for Rx, Tx, error, and wake-up
— Low-pass filter wake-up function
— Loop-back for self test operation
• Timer module (TIM):
— 6-Channel timer
— Each channel configurable as either input capture or output compare
— Simple PWM mode
— Modulo reset of timer counter
— 16-bit pulse accumulator
— External event counting
— Gated time accumulation
• PWM module:
— Programmable period and duty cycle
— 8-bit 4-channel or 16-bit 2-channel
— Separate control for each pulse width and duty cycle
— Center-aligned or left-aligned outputs
— Programmable clock select logic with a wide range of frequencies
— Fast emergency shutdown input
• Serial interfaces:
— One asynchronous serial communications interface (SCI)
— One synchronous serial peripheral interface (SPI)
• CRG (clock reset generator module)
— Windowed COP watchdog
— Real time interrupt
— Clock monitor
— Pierce or low current Colpitts oscillator
— Phase-locked loop clock frequency multiplier
— Limp home mode in absence of external clock
— Low power 0.5MHz to 16MHz crystal oscillator reference clock
