NXP Semiconductors MC9S08AC60MPUE

Overview

MC9S08AC60MPUE from Freescale Semiconductor is an 8-bit HCS08 microcontroller with 60 KB on-chip FLASH, 2 KB RAM, 40-MHz CPU core, and 54 GPIO pins in a 64-pin LQFP package. It integrates dual SCI (LIN 2.0 compliant), I²C, SPI, 16-channel 10-bit ADC, and three TPM timer modules - deployed in automotive body control modules, industrial sensor interfaces, and motor drive supervision systems.

For engineers reviewing the MC9S08AC60MPUE datasheet, MC9S08AC60MPUE pinout, MC9S08AC60MPUE application, or MC9S08AC60MPUE equivalent, key selection criteria include its 20-MHz bus frequency, COP watchdog with independent 1-kHz clock source, on-chip CRC module, and support for Stop2/Stop3 low-power modes with peripheral retention.

Technical Context

The MC9S08AC60MPUE implements the S08CPUV2 core with HC08 instruction set extension including BGND, and operates at up to 40 MHz CPU frequency with 20 MHz internal bus clock. Its memory subsystem includes 60 KB FLASH with block protection and security options, plus 2 KB RAM with hardware CRC acceleration.

Peripherals are managed via dedicated modules: two SCI interfaces supporting LIN 2.0 and SAE J2602, a 100 kbps I²C bus with 10-bit addressing, and three TPM timer modules offering input capture, output compare, and edge-aligned or centered PWM - all configurable under background debug system (BDM) control with breakpoint and ICE trace support.

FAQ

What is the maximum operating frequency of the MC9S08AC60MPUE CPU core?

The MC9S08AC60MPUE 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 (ICG) module with precision NVM trimming, or via external crystal/resonator up to 8 MHz multiplied by on-chip PLL. The 40-MHz specification is validated across commercial temperature range (–40°C to +85°C) per Freescale MC9S08AC60 Series Data Sheet Rev. 3, Section 1.1.

Does the MC9S08AC60MPUE support LIN 2.0 protocol natively?

Yes, the MC9S08AC60MPUE supports LIN 2.0 protocol natively through its dual Serial Communications Interface (SCI) modules. Each SCI implements master extended break generation and slave extended break detection per SAE J2602, enabling direct compliance without external protocol translators. This capability is documented in Section 13.1 of the MC9S08AC60 Series Data Sheet Rev. 3 and verified in application note AN3782.

What power-saving modes are available on the MC9S08AC60MPUE?

The MC9S08AC60MPUE supports Wait mode and two Stop modes: Stop2 and Stop3. Stop2 retains full RAM and register contents with typical current draw below 1 μA; Stop3 adds selective peripheral clock gating for further reduction. Both modes maintain RTC and LVD functionality. These modes are configured via SPMSC1/SPMSC2 registers and detailed in Chapter 3 of the MC9S08AC60 Series Data Sheet Rev. 3.

How many I/O pins does the MC9S08AC60MPUE provide, and what configuration options do they offer?

The MC9S08AC60MPUE provides up to 54 general-purpose I/O pins across Ports A–G. Each pin supports software-selectable internal pullups, slew rate control (fast/normal), and drive strength (low/high). These settings are controlled per-port via PTAPE/PTASE/PTADS registers and enable flexible interfacing with diverse loads - from high-impedance sensors to LED drivers - without external components. Full details appear in Chapter 6 of the MC9S08AC60 Series Data Sheet Rev. 3.

Is the MC9S08AC60MPUE pin-compatible with other members of the MC9S08ACxx series?

Yes, the MC9S08AC60MPUE in the 64-pin LQFP package shares identical pinout with MC9S08AC48CPUE and MC9S08AC32CPUE. All three devices use the same mechanical outline and signal assignment per Section 2.2 of the MC9S08AC60 Series Data Sheet Rev. 3, enabling hardware reuse across memory variants. However, firmware must be validated for FLASH/RAM size differences and peripheral enablement.
