Device Overview MC9S12G-Family
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.
