Device Overview MC9S12XHY-Family

1.1 Introduction

The MC9S12XHY family is an optimized, automotive, 16-bit microcontroller product line that is

speciï¬cally designed for entry level instrument clusters. This family also services generic automotive

applications requiring CAN, LCD, Motor driver control or LIN/SAE J2602. Typical examples of these

applications include instrument clusters for automobiles and 2 or 3 wheelers, HVAC displays, general

purpose motor control and body controllers.

The MC9S12XHY family uses many of the same features found on the MC9S12XS family and

MC9S12HY/HA family, including error correction code (ECC) on ï¬ash memory, a separate data-ï¬ash

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 MC9S12XHY family features a 40x4

liquid crystal display (LCD) controller/driver and a motor pulse width modulator (MC) consisting of up to

16 high current outputs. The device is capable of stepper motor stall detection (SSD) via hardware or

software, please contact Freescale sales ofï¬ce for detailed information on software SSD.

The MC9S12XHY family deliver all the advantages and efï¬ciencies of a 16-bit MCU while retaining the

low cost, power consumption, EMC, and code-size efï¬ciency advantages currently enjoyed by users of

Freescaleâs existing 8-bit and 16-bit MCU families. Like the MC9S12HY/HA family, the MC9S12XHY

family run 16-bit wide accesses without wait states for all peripherals and memories. The MC9S12XHY

family is available in 112-pin LQFP and 100-pin LQFP package options. 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.
