9S12 C Microcontroller Family Overview

9S12C Family MCU Features:

• 19, 33, or 58 I/O lines (depending on package/pincount) with multi-property programmability (eg. input/output, pull-up/pull-down, reduced drive, inverted polarity, etc.)
• up to 8 key wake-up interrupt inputs (with digital filtering)
• 1 x SCI
• 1 x SPI
• 8-channel 10-bit ADCs
• multiple PWM channels
• 4-channel timers supporting input capture/output compare, event counting, gated time accumulation, and simple PWM
• internal memory configuration:
• from 32K to 128K multi-sector Flash
• from 2K to 4K RAM
• fast, high-endurance,  (tens of thousands of erase/write cycles)
• PLL for bus operation up to 25 MHz (over entire voltage and temperature range)
• advanced security features for protecting program memory
• 3.3 V to 5 V operation
• on-chip LVI reset circuit saves external parts
• offered in 48-pin, 52-pin and 80-pin surface-mount packages
