A Comprehensive Guide To S912ZVH128F2VLQ Microcontroller IC 16-Bit 32MHz 128KB (128K x 8) FLASH 144-LQFP (20x20)

S12Z S12 MagniV Microcontroller IC 16-Bit 32MHz 128KB (128K x 8) FLASH 144-LQFP (20x20)

Introduction

The MC9S12ZVH-Family is an optimized automotive 16-bit microcontroller product line focused on low-

cost, high-performance and application component countreduction. This family integrates the components

of an S12HY or S12XHY-family microcontroller with a CAN Physical interface, a 5V regulator system to

supply the microcontroller and other components. The MC9S12ZVH-Family is targeted at automotive &

motorcycle instrument cluster applications requiring CAN connectivity, stepper motor gauges, and

segment LCD displays.

The MC9S12ZVH-Family features a 4x40 liquid crystal display (LCD) controller/driver and a pulse

width modulated motor controller (MC) consisting of up to 16 high current outputs. The device is capable

of stepper motor stall detection (SSD) via hardware or software, please contact Freescale sales office for

detailed information on software SSD.

The MC9S12ZVH-Family delivers an optimized solution with the integration of several key system

components into a single device, optimizing system architecture and achieving significant PCBspace

savings. The MC9S12ZVH-Family delivers all the advantages and efficiencies of a 16-bit MCU while

retaining the low cost, power consumption, EMC, and code-size efficiency advantages currently enjoyed

by users of Freescale's existing 8-bit and 16-bit MCU families. The MC9S12ZVH-Family also features

the revolutionary S12Z CPU with code size & execution efficiencies even higher than our class leading

S12X CPU. This also provides a linear memory map for flash memory for all members of the family,

eliminating the awkwardness and performance impact of page swapping. In addition to the I/O ports

available in each module, further I/O ports are available with interrupt capability allowing wake-up from

stop or wait modes.
