Product details
Overview
S9S08RNA48W1MLC from NXP Semiconductors (formerly Freescale) is an 8-bit S08 microcontroller with 48 KB flash, 256-byte EEPROM with ECC, and 4 KB RAM, operating at up to 20 MHz bus frequency across –40 °C to 125 °C. It integrates ADC (12-bit, 16-channel), three FTM modules, three SCI/UARTs, I²C, SPI, RTC, TSI, and ACMP - designed for automotive body control, industrial sensor nodes, and motor-driven appliance control.
For engineers reviewing the S9S08RNA48W1MLC datasheet, S9S08RNA48W1MLC pinout, S9S08RNA48W1MLC application, or S9S08RNA48W1MLC equivalent, this page delivers verified technical context, validated pin assignments for the 32-pin LQFP package, real-world use cases in harsh-temperature embedded systems, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The S9S08RNA48W1MLC implements the S08 CPU core with nested interrupt support (up to four levels) and on-chip memory protection for flash and RAM. Its clock system combines an external crystal oscillator (XOSC) and internal clock source (ICS) with FLL-based frequency locking, delivering ±2.0% DCO output deviation over –40 °C to 125 °C at full voltage range.
Peripheral integration includes a 12-bit ADC with 2.5 µs conversion time and stop-mode operation, three flex timer modules (FTM) supporting PWM, input capture, and edge-aligned modes, and a touch-sensing interface (TSI) capable of waking the MCU from Stop3 mode using up to 16 electrodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08RN32W1MLC | 32 KB flash, 256-byte EEPROM, same 32-pin LQFP package and peripheral set | Lower memory capacity limits firmware complexity; suitable for cost-sensitive, function-limited designs | Select when application firmware fits within 32 KB and no future feature expansion is planned |
| MC9S08AC60CLC | Same S08 core, 60 KB flash, 48-pin LQFP package; lacks TSI and has different ADC channel count (10 vs. 16) | Higher flash capacity but larger footprint and missing touch interface; requires PCB redesign | Choose only if additional flash is critical and touch sensing is unnecessary; verify pin compatibility before layout reuse |
Compared with S9S08RNA48W1MLC, the S9S08RN32W1MLC offers identical peripheral functionality in the same 32-pin LQFP package but with reduced flash-ideal for footprint-constrained cost optimization. The MC9S08AC60CLC provides more flash but demands a 48-pin layout change and omits TSI, making it unsuitable for touch-enabled applications.

FAQ
What is the maximum bus frequency supported by the S9S08RNA48W1MLC?
The S9S08RNA48W1MLC supports a maximum bus frequency of 20 MHz across its full operating voltage range (2.7 V to 5.5 V) and temperature range (–40 °C to 125 °C). This frequency is achieved using the internal clock source (ICS) with FLL enabled and properly trimmed, or via external crystal oscillator configuration. The S9S08RNA48W1MLC datasheet specifies this as a guaranteed parameter under all qualified conditions.
Does the S9S08RNA48W1MLC support in-application programming (IAP) of flash memory?
Yes, the S9S08RNA48W1MLC supports in-application programming of flash memory - allowing firmware updates or parameter storage while executing code from other flash sectors. Its flash controller enables read/program/erase operations over the full operating voltage and temperature range, and the EEPROM supports concurrent program/erase while running from flash, as confirmed in the S9S08RN60 Series Data Sheet Rev. 1.
What are the key low-power modes available on the S9S08RNA48W1MLC?
The S9S08RNA48W1MLC offers multiple low-power modes including Wait mode (with clocks gated to unused modules) and Stop3 mode - where only the 1 kHz LPO clock remains active, achieving 3.8 µA typical supply current at 5 V. Peripheral clock enable registers allow selective retention of modules like RTC or ADC during Stop3, enabling wake-on-event functionality without full system restart.
Can the S9S08RNA48W1MLC operate from a 3.3 V supply in automotive applications?
Yes, the S9S08RNA48W1MLC operates reliably from 3.3 V across its full –40 °C to 125 °C temperature range. Its DC characteristics specify valid operation from 2.7 V to 5.5 V, and supply current measurements (e.g., RIDD = 7.4 mA at 10 MHz, 3 V) are explicitly characterized at 3 V in the datasheet. This makes it compatible with standard 3.3 V automotive domain controllers and sensor interfaces.
How many analog-to-digital converter (ADC) channels does the S9S08RNA48W1MLC support?
The S9S08RNA48W1MLC supports 16 ADC input channels with 12-bit resolution and 2.5 µs conversion time. These channels are multiplexed onto GPIO pins and include features such as internal bandgap reference selection, optional hardware triggering, data buffering with watermark interrupt, and automatic compare functionality - all confirmed in the S9S08RN60 Series Data Sheet Section 6.3.1.
