12V1 HCS12 Microcontroller IC 16-Bit 25MHz 128KB (128K x 8) FLASH 48-LQFP (7x7)

Introduction

The MC9S12G-Family is an optimized, automotive, 16-bit microcontroller product line focused on

low-cost, high-performance, and low pin-count. This family is intended to bridge between high-end 8-bit

microcontrollers and high-performance 16-bit microcontrollers, such as the MC9S12XS-Family. The

MC9S12G-Family is targeted at generic automotive applications requiring CAN or LIN/J2602

communication. Typical examples of these applications include body controllers, occupant detection, door

modules, seat controllers, RKE receivers, smart actuators, lighting modules, and smart junction boxes.

The MC9S12G-Family uses many of the same features found on the MC9S12XS- and MC9S12P-Family,

including error correction code (ECC) on flash memory, a fast analog-to-digital converter (ADC) and a

frequency modulated phase locked loop (IPLL) that improves the EMC performance. 

The MC9S12G-Family is optimized for lower program memory sizes down to 16k. In order to simplify

customer use it features an EEPROM with a small 4 bytes erase sector size.

The MC9S12G-Family 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 NXP’s

existing 8-bit and 16-bit MCU families. Like the MC9S12XS-Family, the MC9S12G-Family run 16-bit

wide accesses without wait states for all peripherals and memories. The MC9S12G-Family is available in

100-pin LQFP, 64-pin LQFP, 48-pin LQFP/QFN, 32-pin LQFP and 20-pin TSSOP package options and

aims to maximize the amount of functionality especially for the lower pin count packages. 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.

• S12 CPU core

• Up to 240 Kbyte on-chip flash with ECC

• Up to 4 Kbyte EEPROM with ECC

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 theMC9S12XS 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. TheMC9S12VR-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.
