Serial connectivity and peripheral set for control loops
The MC9S08MM32AVLH: Three serial interfaces — I²C, SCI (UART), and SPI — are available for connecting sensors, displays, or a host controller. The 64-LQFP package (10×10 mm body) gives access to 33 I/O pins. The 0.5 mm pitch demands a controlled impedance trace on high-speed lines, but the low pin count keeps the fan-out to two layers in most layouts.
