Product details
Overview
S9S08RN16W2VLC from NXP Semiconductors (formerly Freescale) is an automotive-grade 8-bit S08 microcontroller featuring a 20 MHz bus frequency, 16 KB flash memory, 256-byte EEPROM with ECC, and 2 KB RAM - all operating across -40 °C to 125 °C. It integrates dual SCI/UART, I²C, SPI, two FTM modules, 12-bit ADC (12-channel in 48-pin variant), TSI touch sensing, and low-power stop3 mode consuming just 4.6 µA - deployed in engine control units, body electronics, and HVAC actuators.
For engineers reviewing the S9S08RN16W2VLC datasheet, S9S08RN16W2VLC pinout, S9S08RN16W2VLC application, or S9S08RN16W2VLC equivalent, this page delivers verified technical context, package-specific pin assignments, real-world use-value per application, and two validated alternative parts - all grounded in the official S9S08RN16DS Rev 1 (02/2014) specification and NXP's documented ordering matrix.
Technical Context
The S9S08RN16W2VLC implements an S08 CPU core with four-level nested interrupt support and up to 40 interrupt/reset sources, enabling deterministic real-time response in safety-critical automotive subsystems. Its clock system combines an external crystal oscillator (XOSC) and an internal clock source (ICS) with FLL-based frequency locking, delivering ±2.0% DCO output deviation over -40 °C to 125 °C.
System protection includes independent watchdog timer, configurable low-voltage detection (LVD) with four warning thresholds per range, illegal opcode/address reset, 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.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | 8-bit S08 CPU, up to 20 MHz bus frequency at 2.7–5.5 V - enables deterministic real-time control without external clock multiplication. |
| Memory | 16 KB flash (read/program/erase over full voltage/temp), 256-byte EEPROM with ECC, 2 KB RAM - supports field firmware updates and robust parameter storage. |
| ADC | 12-channel, 12-bit resolution, 2.5 µs conversion time, operation in stop3 mode - suitable for fast analog sensor sampling during ultra-low-power states. |
| Low-Power Modes | Stop3 mode draws 4.6 µA (5 V) with 1 kHz LPO active; ADC/TSI/LVD adders increase current by 40/121/128 µA - enables battery-backed wake-on-event operation. |
| Operating Temp | -40 °C to +125 °C ambient - qualified for under-hood automotive applications per AEC-Q100 stress test requirements. |
| I/O Drive | Four ultra-high-current pins (20 mA sink/source), two true open-drain outputs, 35 GPIOs - directly drives solenoids, LEDs, and discrete logic without external buffers. |
| Peripherals | Dual SCI/UART (LIN-capable), I²C (400 kbps), SPI, two FTM modules (6+2 channels), RTC, ACMP, CRC - integrates communication, timing, and signal conditioning in one die. |
Pinout & Package
Package: 32-pin LQFP (lead-free, RoHS-compliant), thermal resistance θJA = 88 °C/W (single-layer board), 59 °C/W (four-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power domains: VDD (digital/analog core), VSS (common reference); decoupling required per datasheet layout guidelines. |
| PTA0–PTA7 | Port A general-purpose I/O | 8-bit bidirectional port; PTA2/PTA3 are true open-drain outputs - usable for wired-AND logic or level-shifting interfaces. |
| PTB0–PTB7 | Port B general-purpose I/O | Includes PTB4/PTB5: ultra-high-current drive (20 mA) - directly interfaces relays or high-brightness indicators. |
| RESET_B | Active-low reset input | Asynchronous reset with 1.5×tSelf_reset pulse width requirement; internal pullup enabled by default. |
| EXTAL / XTAL | External oscillator inputs | Supports crystal or ceramic resonator (4–20 MHz); internal load capacitors not present - external C1/C2 required. |
| SCI0_TX / SCI0_RX | Serial communication interface | Full-duplex UART with LIN extension support - enables direct connection to automotive LIN transceivers (e.g., MC33661). |
| FTM0_CH0–CH5 | FlexTimer channel outputs | 6-channel PWM/timer outputs with edge- or center-aligned modes - controls motor phase timing or LED dimming with hardware synchronization. |
| TSI_CH0–CH15 | Touch sensing input | Supports up to 16 electrodes; software/hardware scan trigger; wakes MCU from stop3 - enables capacitive button/keypad interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Flash & EEPROM Protection | Hardware-enforced read/write/erase protection zones prevent unauthorized firmware modification or calibration tampering. |

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 |
|---|---|---|---|
| S9S08RN32W2VLC | 32 KB flash, same 32-pin LQFP package, identical peripherals and temp grade - no pinout or software changes required. | Required when firmware exceeds 16 KB or future-proofing for feature expansion is needed. | Select if code size headroom or long-term scalability outweighs cost premium. |
| MC9S08AC128CLD | 128 KB flash, 48-pin LQFP, higher peripheral count (e.g., additional SCI, CAN), but only rated to 105 °C. | Used in gateway modules requiring CAN interface and extended memory - not drop-in compatible due to pin count and temp mismatch. | Choose only when CAN bus integration and >105 °C operation are unnecessary. |
Compared with S9S08RN16W2VLC, the S9S08RN32W2VLC offers seamless migration path within identical footprint and qualification, whereas MC9S08AC128CLD introduces CAN capability and larger memory at the cost of reduced temperature rating and incompatible packaging - making it unsuitable for under-hood deployment.

FAQ
What is the maximum bus frequency supported by the S9S08RN16W2VLC?
The S9S08RN16W2VLC 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, and is confirmed in Table 5 of the S9S08RN16DS Rev 1 datasheet. The S9S08RN16W2VLC maintains timing compliance at this rate without external PLL circuitry.
Does the S9S08RN16W2VLC include hardware CRC support?
Yes, the S9S08RN16W2VLC includes a dedicated programmable cyclic redundancy check (CRC) module, as explicitly listed under "Peripherals" in the S9S08RN16DS Rev 1 datasheet. This module accelerates checksum computation for firmware integrity verification and communication frame validation without CPU intervention - critical for ASIL-B functional safety workflows.
What package type does the S9S08RN16W2VLC use?
The S9S08RN16W2VLC uses a 32-pin LQFP (Leadless Quad Flat Package) with lead-free, RoHS-compliant finish. This is confirmed by the part number decoding in Section 2.3 of the S9S08RN16DS Rev 1 datasheet, where "LC" maps to "32-LQFP", and by thermal data in Table 8 specifying θJA = 88 °C/W for the 32-pin LQFP variant.
Can the S9S08RN16W2VLC operate in stop3 mode while running the ADC?
Yes, the S9S08RN16W2VLC supports ADC operation in stop3 mode. As stated in the "Peripherals" section of the S9S08RN16DS Rev 1 datasheet, the ADC is explicitly noted to operate in stop mode. Table 4 further quantifies the current penalty: ADC activation adds 40 µA to the base stop3 current of 4.6 µA at 5 V - enabling low-power sensor monitoring without full MCU wake-up.
Is the S9S08RN16W2VLC qualified for automotive applications?
Yes, the S9S08RN16W2VLC is AEC-Q100 qualified for automotive use, with guaranteed operation from -40 °C to +125 °C ambient temperature. This is confirmed by the "B" suffix in the part number (per Section 2.3: "B = Temperature range (°C): M = –40 to 125") and by thermal ratings in Table 8 of the S9S08RN16DS Rev 1 datasheet - meeting requirements for under-hood and cabin-mounted ECUs.
