12V1 HCS12 Microcontroller IC 16-Bit 25MHz 128KB (128K x 8) FLASH 64-LQFP (10x10)

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.

Introduction

The MC9S12XD family will retain the low cost, power consumption, EMC and code-size efficiency

advantages currently enjoyed by users of Freescale's existing 16-Bit MC9S12 MCU Family.

Based around an enhanced S12 core, the MC9S12XD family will deliver 2 to 5 times the performance of

a 25-MHz S12 whilst retaining a high degree of pin and code compatibility with the S12.

The MC9S12XD family introduces the performance boosting XGATE module. Using enhanced DMA

functionality, this parallel processing module offloads the CPU by providing high-speed data processing

and transfer between peripheral modules, RAM, Flash EEPROM and I/O ports. Providing up to 80 MIPS

of performance additional to the CPU, the XGATE can access all peripherals, Flash EEPROM and the

RAM block.

The MC9S12XD family is composed of standard on-chip peripherals including up to 512 Kbytes of Flash

EEPROM, 32 Kbytes of RAM, 4 Kbytes of EEPROM, six asynchronous serial communications interfaces

(SCI), three serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, an 8-channel,

10-bit analog-to-digital converter, a 16-channel, 10-bit analog-to-digital converter, an 8-channel

pulse-width modulator (PWM), five CAN 2.0 A, B software compatible modules (MSCAN12), two

inter-IC bus blocks, and a periodic interrupt timer. The MC9S12XD family has full 16-bit data paths

throughout.

The non-multiplexed expanded bus interface available on the 144-pin versions allows an easy interface to

external memories

The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit

operational requirements. System power consumption can be further improved with the new “fast exit from

stop mode” feature.

In addition to the I/O ports available in each module, up to 25 further I/O ports are available with interrupt

capability allowing wake-up from stop or wait mode.

Family members in 144-pin LQFP will be available with external bus interface and parts in 112-pin LQFP

or 80-pin QFP package without external bus interface. SeeAppendix E Derivative Differencesfor package

options.
