12V1 S12 MagniV Microcontroller IC 16-Bit 25MHz 48KB (48K x 8) FLASH 48-LQFP (7x7)

Introduction

The MC9S12VR-Family is an optimized automotive 16-bit microcontroller product line focused on

low-cost, high-performance, and low pin-count. This family integrates an S12 microcontroller with a LIN

Physical interface, a 5V regulator system to supply the microcontroller, and analog blocks to control other

elements of the system which operate at vehicle battery level (e.g. relay drivers, high-side driver outputs,

wake up inputs). The MC9S12VR-Family is targeted at generic automotive applications requiring single

node LIN communications. Typical examples of these applications include window lift modules, seat

modules and sun-roof modules to name a few.

The MC9S12VR-Family uses many of the same features found on the MC9S12G family, including error

correction code (ECC) on 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 MC9S12VR-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 MC9S12VR-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. Like the MC9S12XS family, the

MC9S12VR-Family will run 16-bit wide accesses without wait states for all peripherals and memories.

Misaligned single cycle 16 bit RAM access is not supported. The MC9S12VR-Family will be available in

32-pin and 48-pin LQFP. 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 MC9S12VR-Family is a general-purpose family of devices created with relay based motor control in

mind and is suitable for a range of applications, including:

• Window lift modules

• Door modules

• Seat controllers

• Smart actuators

• Sun roof modules
