It operates up to 48 MHz at ≥2.4 V across –40°C to +105°C and targets low-power industrial sensing and USB-connected embedded control.
For engineers reviewing the MC9S08MM128CLH datasheet, MC9S08MM128CLH pinout, MC9S08MM128CLH application, or MC9S08MM128CLH equivalent, key selection criteria include its ultra-low-power stop3 mode with 64 s TOD timeout, on-chip USB transceiver and 3.3 V regulator, dual SPI interfaces with FIFO, and programmable delay block for synchronized ADC sampling.
Technical Context
The MC9S08MM128CLH implements the HCS08 CPU core with BGND instruction support and handles up to 33 interrupt/reset sources. Its Multipurpose Clock Generator (MCG) provides PLL/FLL-based clock synthesis with 0.2% trimming resolution and supports system frequencies from 4 kHz to 48 MHz using internal or external oscillators.
