NXP Semiconductors MC9S08PL32CLC

Overview

MC9S08PL32CLC from NXP Semiconductors is an 8-bit S08 microcontroller with 32 KB flash, 4 KB RAM, and 256-byte EEPROM, operating up to 20 MHz across –40 °C to +85 °C. It integrates a 16-channel 10-bit ADC, three FlexTimer modules (6+2+2 channels), I²C, three SCI/UART interfaces with LIN support, and on-chip ICE debug. It targets industrial control panels requiring deterministic real-time response and low-power stop modes.

For engineers reviewing the MC9S08PL32CLC datasheet, MC9S08PL32CLC pinout, MC9S08PL32CLC application, or MC9S08PL32CLC equivalent, this page delivers verified technical context, package-specific pin mapping for the 32-pin LQFP, functional peripheral timing constraints, and two validated alternative parts with documented differences in ADC channel count and GPIO availability.

Technical Context

The MC9S08PL32CLC implements an S08 CPU core with four-level nested interrupt handling and supports both FEI (internal FLL) and FBE (external crystal) clock modes. Its ICS includes a frequency-locked loop trimmed for ≤2% deviation over –40 °C to +85 °C, enabling stable 20 MHz bus operation from internal or external sources.

Peripherals include a 16-channel 10-bit ADC with 2.5 µs conversion time and stop-mode operation, three independent FlexTimer modules supporting input capture, output compare, and PWM, plus I²C (400 kbps), three SCI modules with LIN extensions, and CRC hardware acceleration - all accessible via dedicated register sets and interrupt vectors mapped to 40+ configurable interrupt sources.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency and voltage range for the MC9S08PL32CLC?

The MC9S08PL32CLC operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, with full specification guaranteed over the industrial temperature range of –40 °C to +85 °C ambient. Its internal ICS uses a frequency-locked loop with factory-trimmed reference, maintaining ≤2% frequency deviation across that full range.

How many ADC channels does the MC9S08PL32CLC support, and what is its conversion speed?

The MC9S08PL32CLC supports 16 single-ended ADC input channels with 10-bit resolution and a typical conversion time of 2.5 µs. It includes features such as data buffers with optional watermarking, automatic compare function, internal bandgap reference channel, and operation in stop mode - all confirmed in the MC9S08PL60 Series Data Sheet Rev. 4 (2020) applicable to MC9S08PL32 variants.

Does the MC9S08PL32CLC support LIN communication, and which peripherals enable it?

Yes, the MC9S08PL32CLC supports LIN communication through all three integrated SCI modules, each offering optional 13-bit break detection and full-duplex NRZ framing. The SCI modules are explicitly documented as LIN-capable in the MC9S08PL60 Series Data Sheet, and this capability applies identically to the MC9S08PL32CLC as a member of the same product family.

What debug interface does the MC9S08PL32CLC provide, and how many hardware breakpoints are available?

The MC9S08PL32CLC features a single-wire background debug interface (BDM) with on-chip in-circuit emulator (ICE) debug module containing two comparators and nine trigger modes. It supports up to three hardware breakpoints during in-circuit debugging - a capability confirmed in the "Development support" section of the MC9S08PL60 Series Data Sheet applicable to MC9S08PL32.

What is the package type and pin count for the MC9S08PL32CLC, and are there true open-drain outputs?

The MC9S08PL32CLC uses a 32-pin LQFP package (10 mm × 10 mm, 0.8 mm pitch). It includes two true open-drain output pins - PTA2 and PTA3 - explicitly designated as such in the device pin assignment table and functional description within the MC9S08PL60 Series Data Sheet, making them suitable for I²C bus or level-shifting applications.
