S9S12G128AMLH

16位微控制器 - MCU 16BIT 128K FLASH

Introduction S9S12G128AMLH

The MC9S12G-Family is an optimized, automotive, 16-bit microcontroller product line focused on low-cost, high-performance, and low pin-count. This family is intended to bridge between high-end 8-bit microcontrollers and high-performance 16-bit microcontrollers, such as the MC9S12XS-Family.

Main External Oscillator (XOSCLCP)

• Loop control Pierce oscillator using a 4 MHz to 16 MHz crystal

— Current gain control on amplitude output

— Signal with low harmonic distortion

— Low power

— Good noise immunity

— Eliminates need for external current limiting resistor

— Transconductance sized for optimum start-up margin for typical crystals

— Oscillator pins can be shared w/ GPIO functionality

Internal Phase-Locked Loop (IPLL) S9S12G128AMLH

• Phase-locked-loop clock frequency multiplier

— No external components required

— Reference divider and multiplier allow large variety of clock rates

— Automatic bandwidth control mode for low-jitter operation

— Automatic frequency lock detector

— Configurable option to spread spectrum for reduced EMC radiation (frequency modulation)

— Reference clock sources:

– External 4–16 MHz resonator/crystal (XOSCLCP)

– Internal 1 MHz RC oscillator (IRC)

Timer (TIM) S9S12G128AMLH

• Up to eight x 16-bit channels for input capture or output compare

• 16-bit free-running counter with 7-bit precision prescaler

• In case of eight channel timer Version an additional 16-bit pulse accumulator is available
