16位MC9S12P－Family.pdf
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.
