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.

Introduction

The MC9S12P family is an optimized, automotive, 16-bit microcontroller product line focused on lowcost,

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

MC9S12P 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 MC9S12P family uses many of the same features found on the MC9S12XS family, including error

correction code (ECC) on flash memory, a separate data-flash module for diagnostic or data storage, a fast

analog-to-digital converter (ATD) and a frequency modulated phase locked loop (IPLL) that improves the

EMC performance.

The MC9S12P 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

Freescale’s existing 8-bit and 16-bit MCU families. Like the MC9S12XS family, the MC9S12P family run

16-bit wide accesses without wait states for all peripherals and memories. The MC9S12P family is

available in 80-pin QFP, 64-pin LQFP, and 48-pin QFN package options and aims to maximize pin

compatibility with the MC9S12XS family. 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.

Overview

The MC9S12DJ64 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip

peripherals including a 16-bit central processing unit (HCS12 CPU), 64K bytes of Flash EEPROM, 4K

bytes of RAM, 1K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), one

serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit

analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), a digital Byte Data Link

Controller (BDLC), 29 discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital

I/O lines with interrupt and wakeup capability, a CAN 2.0 A, B software compatible modules

(MSCAN12), and an Inter-IC Bus. The MC9S12DJ64 has full 16-bit data paths throughout. However, the

external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower

cost systems. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to

suit operational requirements.
