Product details
Overview
S9S08RNA16W2MLC from NXP Semiconductors (formerly Freescale) is an automotive-grade 8-bit S08 microcontroller with 16 KB flash, 256-byte EEPROM with ECC, and 2 KB RAM, operating at up to 20 MHz bus frequency across –40 °C to 125 °C. It integrates ADC (10-bit, 8-channel), two SCI/UARTs, SPI, I²C, FTM timers, TSI touch sensing, and low-voltage detection - deployed in engine control modules, body electronics, and HVAC actuators.
For engineers reviewing the S9S08RNA16W2MLC datasheet, S9S08RNA16W2MLC pinout, S9S08RNA16W2MLC application, or S9S08RNA16W2MLC equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use-value per application, and two validated alternative parts for functional migration paths in automotive embedded systems.
Technical Context
The S9S08RNA16W2MLC implements an S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources. Its clock system combines a Pierce oscillator (XOSC) with an internal clock source (ICS) featuring a frequency-locked loop (FLL), enabling precise 39.0625 kHz internal reference and ±2.0% DCO output deviation over –40 °C to 125 °C.
System protection includes independent watchdog timer, programmable low-voltage detect (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 (BDM) 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 automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08RNA8W2MLC | 8 KB flash, same 16-pin TSSOP package, identical peripherals and temperature rating | Lower code density; suitable for simpler firmware (e.g., single-sensor nodes) | Select when application firmware fits ≤8 KB and cost sensitivity outweighs future scalability needs. |
| MKE02Z64VQH2 | ARM Cortex-M0+, 64 KB flash, 8 KB RAM, 48 MHz max, 16-pin QFN (3 × 3 mm) | Higher performance, modern toolchain support, but requires PCB redesign and firmware porting | Choose for new designs requiring upgrade path beyond 8-bit constraints; not drop-in compatible. |
Compared with S9S08RNA16W2MLC, the S9S08RNA8W2MLC offers identical pinout and peripheral set at reduced flash capacity, while the MKE02Z64VQH2 provides ARM-based scalability at the cost of layout and software rework - making the former ideal for cost-optimized replacements and the latter for next-generation platforms.

FAQ
What is the maximum bus frequency supported by the S9S08RNA16W2MLC?
The S9S08RNA16W2MLC 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 frequency is achieved using the internal clock source (ICS) with FLL enabled or an external crystal oscillator. The S9S08RNA16W2MLC maintains timing compliance under worst-case voltage and temperature conditions per its AEC-Q100 qualification.
Does the S9S08RNA16W2MLC include EEPROM with error correction?
Yes, the S9S08RNA16W2MLC includes 256 bytes of on-chip EEPROM with built-in error correction code (ECC) for single-bit error detection and correction. This feature ensures data integrity in automotive environments subject to radiation and voltage transients. The S9S08RNA16W2MLC supports 2-byte erase sectors and allows concurrent EEPROM programming/erasing while executing code from flash memory.
Which package type does the S9S08RNA16W2MLC use?
The S9S08RNA16W2MLC uses a 16-pin TSSOP package (designator TG), measuring 3.0 mm × 4.4 mm with 0.65 mm lead pitch. This package is specified in the S9S08RN16 Series Data Sheet Rev 1 (02/2014) and matches the "CC" field value "TG" in the part number format. Thermal resistance is θJA = 130 °C/W on a single-layer board.
Can the S9S08RNA16W2MLC operate in low-power stop modes with peripherals active?
Yes, the S9S08RNA16W2MLC supports Stop3 mode with selected peripherals active, including ADC, TSI, and LVD - each adding defined current (e.g., +40 µA for ADC, +121 µA for TSI). The S9S08RNA16W2MLC achieves 4.6 µA typical supply current in Stop3 with only the 1 kHz LPO clock running, and wake-up latency is deterministic per peripheral configuration.
Is there a pin-compatible alternative with more flash memory in the same package?
No - within the S9S08RN family, the S9S08RNA16W2MLC is the highest-flash-density variant offered in the 16-pin TSSOP (TG) package. Larger flash options (e.g., 32 KB) require 32-pin or 48-pin packages (LC/LF suffixes). Therefore, the S9S08RNA16W2MLC represents the maximum code storage available without changing PCB layout or footprint.
