Product details
Overview
MC9S08QG4CPBE from Freescale Semiconductor is an 8-bit HCS08 microcontroller with 4 KB FLASH, 256 bytes RAM, 20-MHz CPU, internal clock source (ICS) with FLL, and integrated peripherals including 8-channel 10-bit ADC, SCI, SPI, I²C, TPM, ACMP, and KBI - used in cost-sensitive embedded control applications such as appliance motor interfaces and sensor signal conditioning.
For engineers reviewing the MC9S08QG4CPBE datasheet, MC9S08QG4CPBE pinout, MC9S08QG4CPBE application, or MC9S08QG4CPBE equivalent, key selection criteria include its 8-pin SOIC package, single-wire background debug interface, low-voltage detection with reset/interrupt, FLASH block protection, and support for Wait/Stop1/Stop2/Stop3 power-saving modes.
Technical Context
The MC9S08QG4CPBE implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and featuring an on-chip debug module with two comparators, nine trigger modes, and eight-deep FIFO for flow tracing. Its ICS module integrates a frequency-locked loop (FLL) with precision-trimmed internal reference enabling ±0.2% resolution and ±2% deviation over voltage and temperature.
Peripherals include a hardware-triggerable 10-bit ADC with internal bandgap reference and temperature sensor, dual-channel TPM supporting edge-aligned and center-aligned PWM, and serial interfaces (SCI, SPI, I²C) with configurable baud rates and clock sources - all operable in Wait mode and selectively retained in Stop modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08QG8CPBE | Same 8-pin SOIC package and pinout, but with 8 KB FLASH and 512 bytes RAM - no change to I/O, peripherals, or clock architecture. | Supports larger firmware images and more complex state machines; suitable when future feature expansion or bootloader space is required. | Select MC9S08QG8CPBE if firmware size exceeds 4 KB or if design requires headroom for field-upgradable features. |
| S9KEAZ128AMLH | ARM Cortex-M0+ core, 128 KB FLASH, 16 KB RAM, enhanced ADC (16-bit), and additional UART/SPI/I²C instances - different architecture and larger LQFP-64 package. | Targets higher-performance applications requiring real-time OS, cryptographic acceleration, or multi-sensor fusion - not drop-in compatible. | Choose S9KEAZ128AMLH only when migrating to ARM-based platforms with increased processing, memory, or peripheral bandwidth needs. |
Compared with MC9S08QG4CPBE, MC9S08QG8CPBE offers direct pin-compatible scalability within the same footprint and toolchain, while S9KEAZ128AMLH provides architectural upgrade path at the cost of PCB redesign and firmware re-architecture.

FAQ
What is the maximum operating frequency of the MC9S08QG4CPBE CPU?
The MC9S08QG4CPBE features a 20-MHz HCS08 CPU core. Its bus frequency is scalable from 1 MHz to 10 MHz using the internal clock source (ICS) with frequency-locked loop (FLL), or up to 20 MHz when driven by an external clock source. This allows flexible trade-offs between performance, power consumption, and EMI in final system design.
Does the MC9S08QG4CPBE support in-circuit debugging, and what interface is used?
Yes, the MC9S08QG4CPBE supports single-wire background debug via the BKGD/MS pin. It includes an on-chip debug module with two comparators, nine trigger modes, and an eight-deep FIFO for real-time flow tracing - enabling breakpoints, register inspection, and flash programming without requiring additional debug headers or JTAG adapters.
What analog peripherals are integrated into the MC9S08QG4CPBE?
The MC9S08QG4CPBE integrates an 8-channel, 10-bit analog-to-digital converter (ADC) with internal bandgap reference and temperature sensor channel, plus an analog comparator (ACMP) with selectable internal reference and output routable to TPM. These allow direct sensing of voltage, temperature, and threshold events without external signal-conditioning components.
Can the MC9S08QG4CPBE operate from a single supply, and what is its voltage range?
Yes, the MC9S08QG4CPBE operates from a single supply rail (VDD) over 2.7 V to 5.5 V. It includes low-voltage detection (LVD) with programmable threshold and configurable response (reset or interrupt), enabling robust operation across battery-powered and line-powered systems without external voltage supervisors.
Is the MC9S08QG4CPBE pin-compatible with other members of the QG series?
Within the same package variant, yes - the MC9S08QG4CPBE shares identical pinout and electrical characteristics with the MC9S08QG8CPBE in the 8-pin SOIC (CPBE) package. This allows direct hardware compatibility and firmware reuse when upgrading from 4 KB to 8 KB FLASH capacity without PCB changes.
