NXP Semiconductors MC9S08AC60CFUE

Overview

MC9S08AC60CFUE 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 modules supporting LIN 2.0 and SAE J2602, a 16-channel 10-bit ADC, and three timer/PWM modules - deployed in automotive body control modules, industrial sensor nodes, and smart appliance controllers.

For engineers reviewing the MC9S08AC60CFUE datasheet, MC9S08AC60CFUE pinout, MC9S08AC60CFUE application, or MC9S08AC60CFUE equivalent, key selection criteria include its QFN-48 copper-wire package, background debug system with ICE support, COP watchdog with independent 1 kHz clock source, and hardware CRC module for memory integrity verification.

Technical Context

The MC9S08AC60CFUE implements the S08CPUV2 core with HC08 instruction set plus BGND, supports up to 32 interrupt/reset sources, and features an Internal Clock Generator (ICG) with NVM-trimmed precision oscillator.

FAQ

What is the package type and thermal pad configuration of the MC9S08AC60CFUE?

The MC9S08AC60CFUE uses a 48-pin QFN package (document number 98ASA00466D) with an exposed thermal pad. This copper-wire-bonded variant replaces earlier gold-wire versions per Freescale's QFN migration addendum (Rev. 0, 2014). The thermal pad must be soldered to a PCB copper pour for reliable thermal dissipation and electrical grounding.

Does the MC9S08AC60CFUE support LIN 2.0 communication natively?

Yes, the MC9S08AC60CFUE supports LIN 2.0 natively through its dual SCI modules. Each SCI provides master extended break generation and slave extended break detection, meeting SAE J2602 physical layer requirements without external transceivers or software overhead.

How does the background debug system in the MC9S08AC60CFUE differ from standard JTAG interfaces?

The MC9S08AC60CFUE uses a single-wire Background Debug Mode (BDM) interface via the BKGD/MS pin, unlike multi-pin JTAG. It supports breakpoint setting, real-time memory/register access, and ICE trace with minimal pin count - ideal for space-constrained designs where debug visibility must coexist with high I/O density.

Can the MC9S08AC60CFUE operate reliably under low-voltage conditions?

Yes, the MC9S08AC60CFUE includes a configurable Low-Voltage Detect (LVD) system that triggers either a reset or interrupt when VDD drops below a programmable threshold. This feature prevents undefined behavior during brown-out events and is active in all operating modes including Stop2 and Stop3.

What is the maximum ADC sampling rate achievable with the MC9S08AC60CFUE?

The MC9S08AC60CFUE's 10-bit ADC achieves up to 100 kSPS maximum sampling rate when configured with the shortest conversion clock cycle (ADCK = BUSCLK/2). Actual throughput depends on channel count, resolution mode, and bus frequency - at 20 MHz bus clock, typical sustained rate is ~75 kSPS across multiple channels with auto-scan enabled.
