HCS12 HCS12 Microcontroller IC 16-Bit 32MHz 64KB (64K x 8) FLASH 100-LQFP (14x14)

Introduction

The MC9S12HY/HA family is an automotive, 16-bit microcontroller product line that is specifically

designed for entry level instrument clusters. This family also services generic automotive applications

requiring CAN, LCD, Motor driver control or LIN/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 MC9S12HY/HA family uses many of the same features found on the MC9S12P 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 MC9S12HY/HA 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. It

is capable of stepper motor stall detection (SSD), please contact a Freescale sales office for detailed

information.

The MC9S12HY/HA 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 MC9S12HZ family, the MC9S12HY/HA

family run 16-bit wide accesses without wait states for all peripherals and memories. The MC9S12HY/HA

family is available in 100-pin LQFP and 64-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.
