S12Z S12 MagniV Microcontroller IC 16-Bit 50MHz 128KB (128K x 8) FLASH 64-HLQFP (10x10)

Introduction

The MC9S12ZVM-Family is an automotive 16-bit microcontroller family using the NVM + UHV

technology that offers the capability to integrate 40 V analog components. This family reuses many

features from the existing S12/S12X portfolio. The particular differentiating features of this family are the

enhanced S12Z core, the combination of dual-ADC synchronized with PWM generation and the

integration of “high-voltage” analog modules, including the voltage regulator (VREG), Gate Drive Unit

(GDU) and a Local Interconnect Network (LIN) physical layer. These features enable a fully integrated

single chip solution to drive up to 6 external power MOSFETs for BLDC or PMSM motor drive

applications.

The MC9S12ZVM-Family includes error correction code (ECC) on RAM and flash memory, EEPROM

for diagnostic or data storage, a fast analog-to-digital converter (ADC) and a frequency modulated phase

locked loop (IPLL) that improves the EMC performance. The MC9S12ZVM-Family delivers an

optimized solution with the integration of several key system components into a single device, optimizing

system architecture and achieving significant space savings. The MC9S12ZVM-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 existing S12(X) families. The

MC9S12ZVM-Family is available in different pin-out options, using the 64-pin LQFP-EP and 48-pin

LQFP-EP packages to accommodate LIN, CAN and external PWM based application interfaces. 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.

The MC9S12ZVM-Family is a general-purpose family of devices suitable for a range of applications,

including:

• 3-phase sensorless BLDC motor control for

— Fuel pump

— Water pump

— Oil pump

— A/C compressor

— HVAC blower

— Engine cooling fan

— Electric vehicle battery cooling fan

• Brush DC motor control requiring driving in 2 directions, along with PWM control for

— Reversible wiper

— Trunk opener
