Device Overview MC9S12G-Family
MC9S12G Family Reference Manual Rev.1.27
30 NXP Semiconductors
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 NXP’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.
