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 Freescale’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.
