A Comprehensive Guide To S912ZVHL32F1CLQ Microcontroller IC 16-Bit 32MHz 32KB (32K x 8) FLASH 144-LQFP (20x20)

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

Introduction

The MC9S12ZVHY/MC9S12ZVHL Families are optimized automotive 16-bit microcontroller product

families, focused on low-cost, high-performance and application component count reduction. They

integrate many components of the MagniV mixed signal microcontroller S12ZVH-family, including a 5V

regulator system to supply the microcontroller and other components. The MC9S12ZVHYis targeted at

automotive and motorcycle instrument cluster applications requiring stepper motor gauges and segment

LCD displays. Please contact Freescale local representatives for advice on extremely safety constrained

applications. TheMC9S12ZVHLis targeted at automotive and motorcycle instrument cluster applications

requiring stepper motor gauges, segment LCD displays and LIN communications.

The devices 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 devices are capable of stepper

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

information on software SSD.

The MC9S12ZVHY/MC9S12ZVHL Families deliver an optimized solution with the integration ofseveral

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

space savings. These families deliver 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 S12(X) MCU families. TheMC9S12ZVHY/MC9S12ZVHL Families also feature

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

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

inconvenience 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.
