Product details
Overview
MC9S08AC48MFGE from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller designed for cost-sensitive automotive and industrial control applications. It features a 40-MHz CPU core, 48 KB on-chip FLASH memory, 4 KB RAM, 16-channel 10-bit ADC with 2.5 µs conversion time, and integrated LIN 2.0-compliant SCI modules. It operates across –40°C to 125°C and supports low-power Stop2/Stop3 modes with sub-25 µA typical current draw.
For engineers reviewing the MC9S08AC48MFGE datasheet, MC9S08AC48MFGE pinout, MC9S08AC48MFGE application, or MC9S08AC48MFGE equivalent, this page delivers verified functional specifications, package-specific pin mapping for the 48-pin QFN, real-world peripheral integration details (TPM, SPI, I²C, KBI), and validated alternative options for migration or sourcing continuity.
Technical Context
The MC9S08AC48MFGE implements the enhanced HCS08 CPU core with linear address pointer support and memory management unit for paged memory access. Its internal clock generation (ICG) module supports crystal, resonator, or external clock inputs with NVM-trimmed precision, enabling stable operation without external timing components in many configurations.
System-level protection includes configurable COP watchdog with independent clock source, CRC module for memory integrity verification, low-voltage detection with interrupt/reset capability, and illegal opcode detection. Peripheral set includes dual SCI interfaces (LIN 2.0/Sae J2602 compliant), triple TPM modules (2×6-channel + 1×2-channel), and full-duplex SPI with double-buffered transmit/receive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | HCS08 8-bit core with 40-MHz max frequency and 20-MHz bus clock - enables deterministic real-time control at low power. |
| Memory | 48 KB FLASH (read/program/erase over full voltage/temperature range) and 4 KB RAM - sufficient for mid-complexity firmware with secure boot and OTA update support. |
| ADC | 16-channel, 10-bit SAR ADC with 2.5 µs conversion time and internal bandgap reference - suitable for fast sensor sampling (e.g., throttle position, temperature) in automotive subsystems. |
| Communication | Dual SCI (LIN 2.0/J2602 compliant), one SPI (full-duplex, master/slave), and I²C (100 kbps, multi-master) - enables mixed-bus vehicle networks and sensor hub connectivity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08AC48F1 | Same HCS08 core, identical 48-pin QFN package, but rated for –40°C to 105°C only and lacks AEC-Q100 qualification. | Suitable for industrial/commercial use where extended temperature range is not required. | Select when automotive qualification is unnecessary and cost optimization is prioritized over extended temp support. |
| MC9S08AW60CFUE | Higher-end AW-series part with 60 KB FLASH, CAN 2.0B interface, and enhanced ESD/latch-up immunity (±8 kV HBM). | Required for CAN-based vehicle networks (e.g., instrument clusters, powertrain gateways) where LIN-only is insufficient. | Choose when CAN bus integration, larger code space, or higher robustness in noisy environments is mandatory. |

FAQ
What is the maximum operating frequency of the MC9S08AC48MFGE CPU core?
The MC9S08AC48MFGE features an HCS08 CPU core with a maximum clock frequency of 40 MHz, delivering 20 MHz bus speed. This enables deterministic real-time response for time-critical automotive functions such as LIN message scheduling and PWM waveform generation. The core maintains full instruction compatibility with legacy HC08 devices while adding BGND, CALL, and RTC instructions for enhanced debug and timing capabilities.
Does the MC9S08AC48MFGE support LIN 2.0 protocol natively?
Yes, the MC9S08AC48MFGE integrates two SCI modules fully compliant with LIN 2.0 and SAE J2602 protocols. Each SCI supports master extended break generation, slave extended break detection, and wakeup-on-active-edge - eliminating the need for external LIN transceivers in basic slave-node implementations. The on-chip baud rate generator and automatic sync field handling simplify LIN stack development.
What package type and pin count does the MC9S08AC48MFGE use?
The MC9S08AC48MFGE is supplied exclusively in a 48-pin QFN (Quad Flat No-Lead) package with exposed thermal pad. This RoHS-compliant, surface-mount package measures 7 mm × 7 mm with 0.5 mm pitch, offering superior thermal performance and board-space efficiency compared to leaded alternatives - ideal for compact automotive modules where heat dissipation and density are critical.
How much FLASH and RAM memory does the MC9S08AC48MFGE include?
The MC9S08AC48MFGE contains 48 KB of on-chip FLASH memory and 4 KB of RAM. The FLASH supports read/program/erase operations across the full operating voltage (2.7–5.5 V) and temperature (–40°C to 125°C) range, enabling reliable in-field firmware updates. Security circuitry prevents unauthorized access to both FLASH and RAM contents, meeting automotive cybersecurity requirements.
What low-power modes are available on the MC9S08AC48MFGE and their typical current draw?
The MC9S08AC48MFGE supports Wait mode plus two Stop modes: Stop2 and Stop3. At 5 V and 25°C, Stop2 draws ≤25 µA typical, while Stop3 draws ≤27 µA typical - both retain RAM content and support wake-up via SCI, KBI, or RTC. These ultra-low quiescent currents make MC9S08AC48MFGE suitable for always-on vehicle modules powered by standby batteries.
