NXP Semiconductors MC9S08AW60MPUE

Overview

MC9S08AW60MPUE from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 60 KB on-chip FLASH, 2 KB RAM, and a 40-MHz CPU core operating at up to 20-MHz bus frequency. It integrates dual SCI, SPI, I²C, 16-channel 10-bit ADC, two 16-bit TPM modules (2- and 6-channel), KBI, and supports Wait/Stop2/Stop3 low-power modes - deployed in automotive body control modules and industrial sensor nodes.

For engineers reviewing the MC9S08AW60MPUE datasheet, MC9S08AW60MPUE pinout, MC9S08AW60MPUE application, or MC9S08AW60MPUE equivalent, key selection criteria include its 48-pin QFN package with exposed thermal pad, copper-wire interconnect migration per Freescale QFN Addendum Rev. 0 (2014), integrated real-time ICE debug capability, and SuperFlash® technology enabling >100k erase/write cycles.

Technical Context

The MC9S08AW60MPUE implements the S08CPUV2 core with HC08 instruction set extension (BGND), single-wire background debug interface, and on-chip bus capture buffer supporting ~50 instructions pre/post-trigger. Its internal clock generator (S08ICGV4) supports FEI/FEE/FBE modes with NVM-trimmed precision and optional crystal/resonator/external clock inputs.

Peripheral integration includes two independent SCI modules with 13-bit break support, I²C bus operation up to 100 kbps (higher with reduced loading), and dual TPM modules offering input capture, output compare, edge-aligned PWM, and buffered centered PWM (CPWM) on all channels - configurable per channel without shared resource contention.

Key Specifications

Pinout & Package

MC9S08AW60MPUE is housed in a 48-pin QFN package (98ASA00466D) with 7×7 mm footprint, 0.5 mm pitch, and exposed thermal pad - migrated from gold to copper wire bonding per Freescale QFN Addendum Rev. 0 (2014).

FAQ

What is the package type and thermal pad configuration of the MC9S08AW60MPUE?

The MC9S08AW60MPUE uses a 48-pin QFN package (98ASA00466D) with 7×7 mm body, 0.5 mm pitch, and an exposed thermal pad. Per Freescale QFN Addendum Rev. 0 (2014), this variant migrated from gold to copper wire bonding. The thermal pad must be soldered to a PCB copper pour for thermal dissipation and EMI reduction - refer to EB806 for recommended land pattern and solder stencil design.

Does the MC9S08AW60MPUE support in-circuit debugging, and what interface is used?

Yes, the MC9S08AW60MPUE supports real-time in-circuit debugging via a single-wire background debug mode (BDM) interface using the BKGD/MS pin. It includes breakpoint capability (one active breakpoint plus two more in the on-chip debug module) and on-chip bus capture buffer storing approximately 50 instructions before or after a trigger event - enabling deterministic timing analysis without external probes.

What are the clock source options supported by the MC9S08AW60MPUE?

The MC9S08AW60MPUE supports multiple clock sources: external crystal or resonator (via XTAL/EXTAL), external clock signal, or internally generated clock with NVM-trimmed precision. Its S08ICGV4 clock generator operates in FEI (FLL Engaged Internal), FEE (FLL Engaged External), and FBE (FLL Bypassed External) modes - allowing flexible trade-offs between accuracy, startup time, and component count.

How many I/O pins does the MC9S08AW60MPUE provide, and what configurability features are available?

The MC9S08AW60MPUE provides up to 54 general-purpose I/O pins across Ports A–G. Each pin supports software-selectable pullups (reducing external resistor count), slew rate control (to minimize EMI in noisy environments), and drive strength selection (for driving LEDs, relays, or capacitive loads). Pin behavior in Stop modes is individually configurable to maintain state or enter high-impedance.

Is the MC9S08AW60MPUE qualified for automotive applications, and what safety features does it include?

Yes, the MC9S08AW60MPUE is AEC-Q100 Grade 2 qualified for automotive under-hood and cabin applications. It includes system protection features such as computer operating properly (COP) watchdog reset, low-voltage detect (LVD) with reset or interrupt output, illegal opcode detection, and illegal address detection - collectively supporting functional safety requirements for ASIL-B systems in body control modules.
