Product details
Overview
S9S08RN32W1CLC from NXP Semiconductors (formerly Freescale) is an 8-bit S08 core microcontroller designed for automotive and industrial embedded control. It features 32 KB flash, 4 KB RAM, 256-byte EEPROM with ECC, operates at up to 20 MHz bus frequency across –40 °C to 125 °C, and integrates ADC, FTM, SCI, SPI, I²C, TSI, and on-chip debug. It is used in body control modules and motor drive supervision where robustness and mixed-signal integration are required.
For engineers reviewing the S9S08RN32W1CLC datasheet, S9S08RN32W1CLC pinout, S9S08RN32W1CLC application, or S9S08RN32W1CLC equivalent, key selection criteria include its 32-pin LQFP package, -40 °C to 125 °C temperature grade, 32 KB flash/4 KB RAM memory configuration, integrated touch sensing interface (TSI), and support for LIN-compliant SCI UARTs in automotive subsystems.
Technical Context
The S9S08RN32W1CLC implements the S08 CPU core with four-level nested interrupt handling and up to 40 interrupt/reset sources. Its clock system combines an external crystal oscillator (XOSC) and an internal clock source (ICS) with frequency-locked-loop (FLL), enabling precise 1–20 MHz operation with ±2% DCO deviation over –40 °C to 125 °C.
System protection includes independent watchdog timer, low-voltage detection with programmable trip points (2.56 V–4.8 V), illegal opcode/address detection, and flash/RAM access protection. Debug is supported via single-wire background debug mode (BDM) with three breakpoints and on-chip ICE module featuring two comparators and nine trigger modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08RN32CFUE | Same S08RN32 core, identical 32 KB flash/4 KB RAM, but 48-pin QFP package and extended -40 °C to 105 °C temp grade | Requires PCB redesign due to larger footprint and different pinout; suited for non-automotive industrial use with less thermal stress | Select when higher pin count is needed for expanded I/O or when 105 °C max ambient suffices and QFP is preferred for assembly |
| S9KEAZ32AMLH | Kinetis E-series ARM Cortex-M0+ core; 32 KB flash, 4 KB RAM, same 32-pin LQFP; adds USB, more advanced ADC, and lower active current | Software migration required (ARM toolchain vs. S08 CodeWarrior); better for future-proofing or USB host/device needs | Select when upgrading from 8-bit to 32-bit architecture is acceptable and USB connectivity or enhanced analog performance is critical |
Compared with MC9S08RN32CFUE, S9S08RN32W1CLC offers automotive-grade temperature support and smaller 32-pin LQFP packaging, while S9KEAZ32AMLH provides a modern ARM core with USB but demands firmware re-architecture - making S9S08RN32W1CLC optimal for cost-sensitive, drop-in replacements in legacy automotive ECUs.

FAQ
What is the maximum operating bus frequency of the S9S08RN32W1CLC?
The S9S08RN32W1CLC supports a maximum bus frequency of 20 MHz across its full operating voltage range (2.7–5.5 V) and temperature range (–40 °C to 125 °C). This is achieved in FEI or FBE clock modes using the internal ICS with FLL, or via external crystal oscillator (XOSC) in high-range mode. The 20 MHz specification is guaranteed per the datasheet's control timing table (fBus max = 20 MHz).
Does the S9S08RN32W1CLC support LIN communication?
Yes, the S9S08RN32W1CLC supports LIN communication through its three Serial Communication Interface (SCI) modules, each with optional 13-bit break detection and non-return-to-zero (NRZ) framing. The SCI modules comply with LIN 2.1 physical layer requirements and can be configured as LIN master or slave nodes. This capability is explicitly documented in the "Peripherals" section of the S9S08RN60 series datasheet, which covers the S9S08RN32W1CLC.
What is the flash endurance specification for the S9S08RN32W1CLC?
The S9S08RN32W1CLC guarantees 100,000 program/erase cycles for its 32 KB on-chip flash memory over the full operating voltage and temperature range. Flash endurance is specified in the "NVM specifications" section of the S9S08RN60 series datasheet, and applies identically to all members of the RN32/RN48/RN60 family, including S9S08RN32W1CLC.
Can the S9S08RN32W1CLC operate from a 3.3 V supply?
Yes, the S9S08RN32W1CLC operates reliably from a 3.3 V supply. Its specified operating voltage range is 2.7 V to 5.5 V, and all electrical characteristics-including bus frequency (up to 20 MHz), I/O drive strength, ADC performance, and low-power mode currents-are validated across this range, including at 3 V. DC characteristics tables in the datasheet provide explicit 3 V test conditions for VOH, VOL, VIH, and supply current.
How many GPIO pins does the S9S08RN32W1CLC provide in its 32-pin LQFP package?
The S9S08RN32W1CLC provides up to 28 GPIO pins in its 32-pin LQFP package. Of the 32 pins, four are dedicated to power (VDD, VSS ×2, VDDA) and reset/debug (RESET, BKGD), leaving 26 general-purpose I/O pins across Port A (8 pins) and Port B (8 pins), plus additional multiplexed functions such as ADC inputs, SCI, SPI, and I²C signals that can be configured as GPIO when peripherals are disabled.
