For best experience this site requires Javascript to be enabled. To enable on your browser, follow our accessibility instructions.

The MC9S12H128 MCU is a 16-bit device composed of standard on-chip peripherals, including a HCS12 CPU.

The MC9S12H128 has full 16-bit data paths throughout.

The inclusion of a PLL circuit allows power consumption and performance to be adjusted.

In addition to the I/O ports available in each module, 12 general-purpose I/O pins are available with interrupt and wake-up capability from STOP or WAIT mode.

Note: Documentation for this device has been structured in a modular form. For the complete set of user guides, download the ZIP file.
