Product details
Overview
MC9S08QE8CPG from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 8 KB flash, 512 B RAM, and integrated peripherals including 12-bit ADC, dual analog comparators, SCI, SPI, I²C, two 16-bit TPM modules, RTC, and single-wire background debug interface. It operates from 1.8 V to 3.6 V at up to 20 MHz and supports ultra-low-power stop3 mode (0.4 µA typical). It is used in battery-powered industrial sensors and embedded control systems requiring precise timing and mixed-signal integration.
For engineers reviewing the MC9S08QE8CPG datasheet, MC9S08QE8CPG pinout, MC9S08QE8CPG application, or MC9S08QE8CPG equivalent, key selection criteria include its 32-pin QFN package (case 2078-01), 12-bit ADC with temperature sensor, dual ACMPs operational in stop3, LIN-capable SCI, and verified 6 µs wake-up from stop3 - all critical for low-power, real-time edge-node designs.
Technical Context
The MC9S08QE8CPG implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with factory-trimmed internal reference (±2% deviation over voltage/temperature), enabling bus frequencies from 1 MHz to 10 MHz without external crystal.
Power management includes two stop modes (stop2/stop3), reduced-power wait, and peripheral clock gating. The stop3 mode retains RTC operation using a dedicated 1 kHz low-power oscillator, and the ADC remains fully functional down to 1.8 V - enabling continuous sensing during deep sleep.

FAQ
What is the maximum operating frequency of the MC9S08QE8CPG and under what conditions?
The MC9S08QE8CPG supports up to 20 MHz CPU operation across its full temperature range (–40 °C to +85 °C) at supply voltages from 1.8 V to 3.6 V. This is achieved using the internal clock source (ICS) with FLL enabled and proper configuration of the trim register. At 10 MHz bus frequency, typical run current is 5.6 mA at 3.0 V and 25 °C.
Does the MC9S08QE8CPG support true hardware LIN communication?
Yes, the MC9S08QE8CPG's SCI module provides dedicated hardware support for LIN 2.x, including automatic extended break generation (for master) and extended break detection (for slave), along with sync field handling and checksum calculation. No firmware bit-banging is required, reducing CPU load and ensuring timing compliance.
Can the MC9S08QE8CPG ADC operate while the device is in stop3 mode?
Yes, the 12-bit ADC in the MC9S08QE8CPG remains fully functional in stop3 mode, including automatic channel sequencing, compare function, and temperature sensor readout. It operates from 3.6 V down to 1.8 V, enabling continuous low-power data acquisition without waking the CPU - critical for energy-constrained sensor nodes.
What is the wake-up time from stop3 mode for the MC9S08QE8CPG?
The MC9S08QE8CPG has a typical wake-up time of 6 µs from stop3 mode, measured from interrupt assertion to first instruction fetch. This specification is guaranteed across –40 °C to +85 °C and 1.8 V to 3.6 V, enabling rapid response to external events such as ACMP threshold breaches or RTC alarms.
Is the MC9S08QE8CPG pin-compatible with other members of the QE8 series?
Yes, the MC9S08QE8CPG shares identical pinout across all 32-pin packages (QFN and LQFP) in the QE8 series, including MC9S08QE4CPG. However, pin compatibility does not imply functional equivalence: MC9S08QE4CPG has only 4 KB flash and 256 B RAM, and lacks some peripheral features present in the QE8 variant.
