Product details
Overview
MC9S08AC8MFGE from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 8 KB flash, 512 B RAM, 40-MHz CPU, and integrated peripherals including dual SCI, SPI, I²C, 10-bit ADC, and three 16-bit TPM timer modules. It operates at 20-MHz bus frequency and supports automotive-grade temperature range (–40°C to 125°C) in a 48-pin QFN package with exposed thermal pad.
For engineers reviewing the MC9S08AC8MFGE datasheet, MC9S08AC8MFGE pinout, MC9S08AC8MFGE application, or MC9S08AC8MFGE equivalent, this device is selected for cost-sensitive, low-power embedded control in automotive body electronics, industrial sensor nodes, and consumer appliance motor control where on-chip debug, flash security, and mixed-signal integration are required.
Technical Context
The MC9S08AC8MFGE implements the S08CPUV2 core with HC08 instruction set extension (BGND), background debugging system (BDM), and eight-deep FIFO trace buffer. Its internal clock generator (S08ICGV4) supports multiple modes - FEI, FEE, FBE - with NVM-trimmed internal reference and external crystal/resonator options up to 4 MHz.
Peripherals include two independent SCI modules with 13-bit break detection, one SPI module (V3), one I²C module (V2) compliant with standard-mode (100 kbps), and an 8-channel 10-bit ADC with auto-compare. Three TPM modules provide flexible PWM, input capture, and output compare with buffered center-aligned PWM capability on all channels.

Pinout & Package
MC9S08AC8MFGE is housed in a 48-pin quad flat no-lead (QFN) package per document 98ASA00466D, featuring an exposed thermal pad for enhanced heat dissipation and mechanical stability. Pin assignments follow Freescale's standardized HCS08 AC-series layout with dedicated VDDAD/VSSAD analog supply pins, dual VSS ground pins, and BKGD/MS for BDM interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDAD | Power supply inputs | VDD = digital core (2.7–5.5 V); VDDAD = analog domain - separate supplies reduce noise coupling into ADC |
| VSS, VSSAD | Ground returns | Dual ground paths isolate digital switching noise from analog reference and ADC conversion |
| BKGD/MS | Background debug / mode select | Single-pin BDM interface for in-circuit programming and real-time debugging without dedicated JTAG header |
| XTAL / EXTAL | Clock oscillator terminals | Supports external crystal (32 kHz–4 MHz) or resonator; internal trimming enables stable bus clock without external components |
| PTA0–PTA7 | Port A general-purpose I/O | 8-bit port with software-selectable pullups, slew rate, and drive strength - configurable as ADC inputs or SCI/I²C signals |
| PTF0–PTF7 | Port F general-purpose I/O | Includes IRQ interrupt input and TPM channel outputs - supports edge-triggered wake-up from Stop2/Stop3 modes |
Key Features
| Feature | Design Value |
|---|---|
| On-chip debug module | Two comparators, nine trigger modes, and eight-deep FIFO enable non-intrusive code flow tracing and breakpoint management during live operation |
| FLASH security & protection | Block-level write/erase protection and NVOPT-based security lock prevent unauthorized firmware readout or overwrite in production units |
| Low-voltage detection (LVD) | Configurable reset or interrupt on VDD drop below threshold - ensures safe shutdown before logic corruption in brown-out conditions |
| Power-saving modes | Wait, Stop2, and Stop3 modes with selective peripheral clock gating - achieves sub-1 µA current draw while retaining RAM and wake-up capability |
| ADC temperature sensor | Integrated bandgap-based temperature sensor with calibrated output - enables ambient monitoring without external components |

FAQ
What is the maximum operating frequency of the MC9S08AC8MFGE CPU core?
The MC9S08AC8MFGE CPU core runs at a maximum frequency of 40 MHz, while its internal bus operates at up to 20 MHz. This frequency is achieved using the internal clock generator (ICG) in FEE or FEI mode with appropriate configuration of the ICGTRM and ICGC1 registers. The MC9S08AC8MFGE supports both internal trimmed RC oscillation and external crystal/resonator sources for clock generation.
Does the MC9S08AC8MFGE support in-circuit debugging without external hardware?
Yes, the MC9S08AC8MFGE integrates a background debug module (BDM) accessible via the single BKGD/MS pin, enabling full in-circuit programming, real-time register inspection, and breakpoint execution without JTAG adapters. The MC9S08AC8MFGE debug system includes two comparators, nine trigger modes, and an eight-deep FIFO for non-intrusive trace capture during active operation.
What are the power supply requirements for the MC9S08AC8MFGE analog and digital domains?
The MC9S08AC8MFGE requires separate analog (VDDAD/VSSAD) and digital (VDD/VSS) supply connections to ensure ADC accuracy and noise immunity. Both domains accept 2.7–5.5 V, but VDDAD must be decoupled with a 100 nF capacitor close to the pin. The MC9S08AC8MFGE datasheet specifies that VDDAD should not differ from VDD by more than ±0.3 V to maintain specification compliance.
Can the MC9S08AC8MFGE generate center-aligned PWM waveforms?
Yes, the MC9S08AC8MFGE's three TPM modules support buffered center-aligned PWM (CPWM) on all channels when configured in CPWM mode. Each TPM channel can independently operate in edge-aligned or center-aligned mode, and the MC9S08AC8MFGE allows synchronization between modules for multi-phase motor control. CPWM reduces harmonic content and EMI in motor drive applications.
Is the MC9S08AC8MFGE qualified for automotive applications?
Yes, the MC9S08AC8MFGE is AEC-Q100 qualified for Grade 1 (–40°C to +125°C) operation and features automotive-specific enhancements including enhanced ESD tolerance, robust LVD detection, and COP watchdog with independent clock source. The MC9S08AC8MFGE is listed in Freescale's automotive product portfolio alongside MC9S08AW8A and MC9S08AW16A variants.
