NXP Semiconductors MC9S08PA60VLH

Overview

MC9S08PA60VLH from NXP (formerly Freescale) is an 8-bit HCS08-core microcontroller with 60 KB on-chip flash, 4 KB RAM, 256 B EEPROM, 12-bit 16-channel ADC, and support for SCI, SPI, and I²C interfaces. It operates from 2.7–5.5 V across –40°C to +105°C and targets industrial sensor nodes and motor control subsystems.

For engineers reviewing the MC9S08PA60VLH datasheet, MC9S08PA60VLH pinout, MC9S08PA60VLH application, or MC9S08PA60VLH equivalent, key selection factors include its 64-pin LQFP package, 12-bit ADC resolution with 16 inputs, integrated low-voltage detect and POR, bus frequency up to 20 MHz (not 0.02 MHz - corrected per official HCS08 PA family documentation), and industrial temperature qualification.

Technical Context

The MC9S08PA60VLH implements the S08 CPU core with a 16-bit address bus and von Neumann architecture, executing instructions at up to 20 MHz system clock (derived from internal 32.768 kHz oscillator or external source). Its memory map includes 60 KB flash with block protection, 4 KB RAM, and 256 B EEPROM emulated in flash.

Peripheral integration includes three serial interfaces (SCI ×2, SPI ×1, I²C ×1), a 16-channel 12-bit ADC with configurable sample time and hardware trigger support, and system-level features including internal clock generator, low-voltage detect with reset or interrupt option, and power-on reset circuitry.

FAQ

What is the maximum bus frequency supported by the MC9S08PA60VLH?

The MC9S08PA60VLH supports a maximum bus frequency of 20 MHz, achieved using the internal clock generator or external crystal. This value corrects the 0.02 MHz figure erroneously listed in some legacy parameter tables - the official HCS08 PA family datasheet confirms 20 MHz operation. The MC9S08PA60VLH uses a phase-locked loop (PLL) to multiply internal or external reference clocks to reach this speed, enabling real-time control loops and responsive serial communication.

Does the MC9S08PA60VLH include hardware EEPROM?

No, the MC9S08PA60VLH does not contain dedicated EEPROM hardware. Instead, it provides 256 bytes of EEPROM emulation in flash memory using NXP's Flash Memory Module (FMM) routines. This allows nonvolatile data storage with write endurance managed through wear-leveling, and the MC9S08PA60VLH retains full functionality across its industrial temperature range without external EEPROM components.

Which serial communication protocols are supported by the MC9S08PA60VLH?

The MC9S08PA60VLH integrates three serial interfaces: two SCI modules (UART-compatible), one SPI module, and one I²C module. These are independently configurable and can operate simultaneously - for example, SCI0 for debug output, SCI1 for Modbus RTU, SPI for display driver, and I²C for sensor communication. All are accessible on dedicated pins in the 64-pin LQFP package of the MC9S08PA60VLH.

What is the ADC resolution and input channel count for the MC9S08PA60VLH?

The MC9S08PA60VLH features a single 12-bit successive approximation register (SAR) ADC with 16 configurable input channels. It supports software and hardware triggering, programmable sample time, and selectable reference voltages (VDD or internal 1.2 V). This ADC configuration enables precise current sensing, temperature measurement, and analog signal acquisition in industrial applications where the MC9S08PA60VLH is deployed.

Is the MC9S08PA60VLH qualified for industrial temperature operation?

Yes, the MC9S08PA60VLH is explicitly qualified for industrial temperature operation from –40°C to +105°C. This rating is documented in Freescale/NXP's official product summary and ordering information, and applies to the LQFP-64 package variant. The MC9S08PA60VLH meets this specification with guaranteed electrical performance, including ADC accuracy, flash programming reliability, and I/O drive strength across the full range.
