The MC9S12XHY family is an optimized, automotive, 16-bit mICrocontroller product line focused on low-cost and high-performance. This family is intended to bridge from low-end 16-bit microcontrollers, such as MC9S12HY family, to high performance 32-bit solutions. The MC9S12XHY family is targeted at the lower end of automotive instrument cluster applications, it includes support for CAN and LIN/J2602 communication and delivers typical cluster requirements such as stepper motor control with stepper stall detection (SSD) and LCD Driver.
The MC9S12XHY 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 MC9S12HY family, the MC9S12XHY family will run 16-bit wide accesses without wait states for all peripherals and memories. The MC9S12XHY family will be available in 100-PIN LQFP and 112-pin LQFP PACkage options and aims to maximize pin compatibility with the MC9S12HY family in the 100 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.
