Product details
Overview
S9S08RN48W1MLCR from NXP Semiconductors (formerly Freescale) is an 8-bit S08 core microcontroller designed for automotive and industrial control applications requiring robust operation across -40 °C to 125 °C. It integrates 48 KB flash, 4 KB RAM, 256 B EEPROM with ECC, a 12-bit 16-channel ADC, three FTM timer modules, and dual SCI/UART interfaces - all operating at up to 20 MHz bus frequency on 2.7–5.5 V supply.
For engineers reviewing the S9S08RN48W1MLCR datasheet, S9S08RN48W1MLCR pinout, S9S08RN48W1MLCR application, or S9S08RN48W1MLCR equivalent, this page delivers verified technical context, validated package mapping (48-pin LQFP), confirmed peripheral capabilities, real-world use scenarios, and two rigorously cross-checked alternative parts - all grounded in the official S9S08RN60 Series Data Sheet Rev. 1 (01/2014).
Technical Context
The S9S08RN48W1MLCR implements the S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines an external crystal oscillator (XOSC) and an internal clock source (ICS) featuring a frequency-locked loop (FLL), enabling precise 20 MHz operation with ±2.0% total DCO deviation over -40 °C to 125 °C.
System protection includes independent watchdog timing, configurable low-voltage detection (LVD) with four warning thresholds per range, illegal opcode/address detection, and flash/RAM access protection. Debug is enabled via single-wire background debug interface with three breakpoints and on-chip ICE module supporting 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 |
|---|---|---|---|
| MC9S08AC60CFUE | Same S08 core, 60 KB flash, 4 KB RAM, but 64-pin QFP; lacks TSI and has only two SCI modules | Better suited for high-pin-count designs needing more GPIO or CAN interface (via external transceiver), less ideal for touch-enabled compact devices | Select when higher flash capacity and additional I/O are prioritized over capacitive touch integration and 48-pin footprint. |
| S9KEAZN64AMLH | Kinetis E-series ARM Cortex-M0+, 64 KB flash, 8 KB RAM, 12-bit ADC, but no TSI; operates at 48 MHz; different debug interface (SWD) | Offers higher performance and modern toolchain support, but requires PCB redesign, new firmware architecture, and lacks native touch-sensing hardware | Choose for new designs targeting future scalability, RTOS compatibility, or higher computational throughput - not as drop-in replacement. |
Compared with MC9S08AC60CFUE and S9KEAZN64AMLH, the S9S08RN48W1MLCR uniquely balances legacy S08 software continuity, integrated TSI for human-machine interface, and automotive-grade packaging in a 48-pin LQFP - making it optimal for cost-sensitive, space-constrained, touch-enabled control nodes where migration to ARM is not justified.

FAQ
What is the maximum operating frequency and voltage range for the S9S08RN48W1MLCR?
The S9S08RN48W1MLCR operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, fully specified over the industrial temperature range of -40 °C to 125 °C. This allows direct interfacing with 3.3 V and 5 V systems without level-shifting, and supports stable timing-critical functions like motor PWM generation and LIN communication at full speed.
Does the S9S08RN48W1MLCR include hardware-based touch sensing capability?
Yes, the S9S08RN48W1MLCR integrates a Touch Sensing Interface (TSI) module supporting up to 16 external electrodes, with configurable software or hardware scan triggers and full compatibility with Freescale's touch sensing software library. It can wake the MCU from stop3 mode, enabling ultra-low-power capacitive button or slider implementations - a key differentiator versus standard S08 variants.
What package type and pin count does the S9S08RN48W1MLCR use?
The S9S08RN48W1MLCR is packaged in a 48-pin LQFP (Lead-Free, RoHS-compliant) with exposed pad option not specified. Its pinout matches the S9S08RN60 and S9S08RN32 family members in the 48-pin variant, enabling shared PCB layouts across flash-size variants. Thermal resistance is θJA = 81 °C/W (single-layer) and 57 °C/W (four-layer board).
How much EEPROM and RAM does the S9S08RN48W1MLCR provide?
The S9S08RN48W1MLCR includes 256 bytes of EEPROM with built-in ECC for reliable nonvolatile data storage, and 4096 bytes (4 KB) of on-chip RAM. The EEPROM supports 2-byte erase sectors and allows concurrent program/erase operations while executing code from flash - essential for robust data logging in automotive and industrial applications where power loss must not corrupt stored parameters.
Is the S9S08RN48W1MLCR qualified for automotive applications?
Yes, the S9S08RN48W1MLCR is fully qualified for automotive use with guaranteed operation from -40 °C to 125 °C, AEC-Q100 stress testing compliance, ±6 kV HBM ESD rating, and latch-up immunity to ±100 mA.
