Product details
Overview
MC9S08AW48CFUER from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 48 KB Flash, 1.5 KB RAM, 48-pin QFN package, and integrated peripherals including dual SCI, SPI, I²C, 16-channel 10-bit ADC, and dual TPM modules - used in automotive body control modules and industrial sensor interfaces.
For engineers reviewing the MC9S08AW48CFUER datasheet, MC9S08AW48CFUER pinout, MC9S08AW48CFUER application, or MC9S08AW48CFUER equivalent, key selection criteria include Flash size vs. code footprint, QFN thermal performance under 105°C ambient, BDM debug interface compatibility, and peripheral mix for mixed-signal embedded control.
Technical Context
The MC9S08AW48CFUER implements the S08CPUV2 core with 40-MHz CPU clock and 20-MHz bus frequency, supporting single-wire background debug mode (BDM) and real-time in-circuit emulation with nine trigger modes. Its internal clock generator (ICGV4) supports FLL-engaged modes (FEI/FEE), crystal/resonator inputs, and NVM-trimmed internal reference.
Peripherals are memory-mapped and share a unified interrupt vector table supporting up to 32 sources. The dual TPM modules provide configurable input capture, output compare, edge-aligned PWM, and buffered centered PWM (CPWM) on all channels - enabling motor control and LED dimming without external timing ICs.

FAQ
What is the maximum operating frequency of the MC9S08AW48CFUER CPU core?
The MC9S08AW48CFUER CPU core operates at up to 40 MHz, with a corresponding 20-MHz internal bus frequency. This timing is achieved using the internal clock generator (ICGV4) in FLL-engaged modes (FEI/FEE) or with external crystal/resonator inputs. The 40-MHz CPU clock enables real-time response for motor control loops and communication protocol handling without external acceleration.
Does the MC9S08AW48CFUER support in-circuit debugging, and what interface is used?
Yes, the MC9S08AW48CFUER supports in-circuit debugging via a single-wire background debug mode (BDM) interface using the BKGD/MS pin. It includes breakpoint capability (one hardware breakpoint plus two more in the on-chip debug module) and real-time in-circuit emulation with bus capture buffer - allowing engineers to observe ~50 instructions before or after a trigger event during development of MC9S08AW48CFUER-based systems.
What are the Flash memory configuration options for the MC9S08AW48CFUER?
The MC9S08AW48CFUER contains 48 KB of on-chip FLASH memory with block protection, security options, and 512-byte erase sectors. Configuration is managed through dedicated registers including FOPT/NVOPT (for security and reset behavior), FPROT/NVPROT (for protection zones), and FCNFG (for burst programming). These settings allow selective locking of bootloader sections and prevention of unauthorized firmware readout - critical for MC9S08AW48CFUER deployments in regulated environments.
How does the MC9S08AW48CFUER handle low-voltage conditions?
The MC9S08AW48CFUER integrates a configurable low-voltage detection (LVD) system that can generate either a reset or interrupt at user-selectable thresholds (2.5 V or 2.7 V). This feature ensures deterministic behavior during brown-out events - preventing corrupted FLASH writes or erratic peripheral operation. When combined with Stop2/Stop3 power-saving modes, the LVD system enables reliable wake-up and recovery in battery-powered MC9S08AW48CFUER applications.
Can the MC9S08AW48CFUER drive high-current loads directly from its GPIO pins?
No, the MC9S08AW48CFUER GPIO pins are not rated for high-current loads; each port pin supports up to 20 mA sink/source with total package current limited to 100 mA. For driving motors, relays, or LEDs above this level, external drivers (e.g., MOSFETs or dedicated gate drivers) must be used. However, the MC9S08AW48CFUER does provide software-selectable drive strength and slew rate control to optimize EMI and signal integrity when interfacing with such external circuitry.
