Product details
Overview
PC9S08QE128CLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller featuring 128 KB flash, 8 KB RAM, 70 GPIOs, 24-channel 12-bit ADC, dual analog comparators, and triple timer/PWM modules - designed for low-power industrial control and sensor interface applications operating from 1.8 V to 3.6 V.
For engineers reviewing the PC9S08QE128CLH datasheet, PC9S08QE128CLH pinout, PC9S08QE128CLH application, or PC9S08QE128CLH equivalent, key selection criteria include its 48-pin QFN package with exposed pad, stop-mode wake-up time of 6 μs, integrated real-time counter with 1-kHz low-power oscillator, and support for LIN, I²C, SPI, and SCI protocols in resource-constrained embedded systems.
Technical Context
The PC9S08QE128CLH implements the HCS08 CPU core with BGND instruction support and up to 50.33 MHz operation above 2.4 V. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with factory-trimmed internal reference enabling ±0.2% resolution and ±2% deviation across voltage/temperature.
System-level timing is managed via three independent timer/PWM modules: TPM1 (3-channel), TPM2 (3-channel), and TPM3 (6-channel), each supporting input capture, output compare, and edge-/center-aligned PWM. The real-time counter (RTC) operates in run, wait, and stop modes using either internal 1-kHz oscillator or external clock source.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+ core; 128 KB flash, 16 KB RAM; higher performance but larger code size and power consumption | Requires ARM toolchain and different peripheral drivers; better suited for applications needing >50 MHz throughput or USB connectivity | Select when migrating from 8-bit to 32-bit architecture with need for future scalability and richer peripheral set |
| MC9S08AC128CLD | Same HCS08 core; 128 KB flash, 4 KB RAM; 48-pin LQFP package; lacks RTC, second I²C, and one TPM module | Lower peripheral count limits use in multi-sensor or multi-bus systems; suitable for cost-sensitive fixed-function controllers | Select when RTC, dual I²C, or 6-channel PWM are not required and LQFP assembly is preferred over QFN |
Compared with S9KEAZ128AMLH and MC9S08AC128CLD, PC9S08QE128CLH delivers optimal balance of analog integration (24-channel ADC, dual ACMP), low-power timing (RTC + 1-kHz oscillator), and compact QFN packaging - making it ideal for space-constrained, battery-aware, and sensor-rich designs where 8-bit efficiency remains advantageous.

FAQ
What is the maximum operating frequency of the PC9S08QE128CLH and under what voltage conditions?
The PC9S08QE128CLH achieves up to 50.33 MHz CPU operation when supplied at ≥2.4 V across the full temperature range (–40°C to +85°C). At 2.1 V, maximum frequency is 40 MHz; at 1.8 V, it is 20 MHz. These ratings are guaranteed per the MC9S08QE128 Rev. 7 datasheet Section 1 and Table 1, and apply specifically to the PC9S08QE128CLH in its 48-pin QFN package.
Does the PC9S08QE128CLH support hardware debugging, and what interface is used?
Yes, the PC9S08QE128CLH supports in-circuit debugging via a single-wire background debug interface (BDC) compliant with Freescale's BDM specification. It provides breakpoint capability (one active breakpoint plus two additional), on-chip ICE debug module with eight-deep FIFO, and tag/force breakpoint support - all accessible through the PTA4/BKGD pin without requiring additional debug headers or pins.
What are the key low-power features of the PC9S08QE128CLH relevant to battery-operated devices?
The PC9S08QE128CLH offers two stop modes and a reduced-power wait mode, with 6 μs typical wake-up time from stop. Its very low power real-time counter (RTC) runs continuously using an internal 1-kHz oscillator, enabling periodic wake-up without external components. The ADC and ACMP modules remain functional in stop3 mode, allowing sensor sampling with minimal current draw - critical for extending battery life in remote sensor nodes.
Can the PC9S08QE128CLH operate reliably in automotive environments, and what qualifications does it meet?
The PC9S08QE128CLH meets AEC-Q100 stress test qualification for automotive grade ICs, including human body model (±2000 V), machine model (±200 V), and charge device model (±500 V) ESD testing. Its operating temperature range of –40°C to +85°C, LVD circuit with selectable thresholds, and COP watchdog with dedicated 1-kHz clock source make it suitable for non-safety-critical automotive body electronics such as door modules and lighting controllers.
How many analog-to-digital converter channels does the PC9S08QE128CLH have, and what is their resolution and speed?
The PC9S08QE128CLH integrates a 24-channel, 12-bit successive approximation register (SAR) ADC with a 2.5 μs conversion time per sample. It includes an internal 1.7 mV/°C temperature sensor, bandgap reference channel, and automatic compare function. The ADC operates fully from 3.6 V down to 1.8 V and remains functional in stop3 mode - confirmed in the MC9S08QE128 Rev. 7 datasheet Section 1 and Table 3.12.
