Product details
Overview
S9S12G192F0VLLR from NXP Semiconductors is a 16-bit automotive-grade microcontroller featuring 192 KB on-chip Flash with ECC, 12 KB SRAM, and integrated CAN 2.0B controller. It operates at up to 50 MHz via internal PLL, supports -40°C to +105°C ambient, and targets engine control, body electronics, and chassis modules requiring ASIL-B capable MCU-level safety features.
For engineers reviewing the S9S12G192F0VLLR datasheet, S9S12G192F0VLLR pinout, S9S12G192F0VLLR application, or S9S12G192F0VLLR equivalent, key selection criteria include its 112-pin LQFP package, 10-bit ADC with 16 channels, 8-channel PWM with dead-time insertion, and BDM debug interface - all validated for AEC-Q100 Grade 2 compliance.
Technical Context
The S9S12G192F0VLLR implements the S12 CPU12 core with 16-bit data path and 24-bit addressing, executing instructions in single-cycle (most) or two-cycle (indexed) modes. Its memory subsystem includes 192 KB Flash organized in 2 KB sectors with error correction, 12 KB SRAM, and 1 KB EEPROM emulation via Flash.
Peripherals are tightly coupled via the Port Integration Module (PIM), enabling flexible signal routing to 112 I/O pins. Clocking uses dual sources: a 1–8 MHz external crystal or ceramic resonator plus an internal 1–8 MHz RC oscillator, with PLL multiplication to 50 MHz system clock.

FAQ
What is the maximum operating frequency of the S9S12G192F0VLLR?
The S9S12G192F0VLLR achieves a maximum system clock frequency of 50 MHz using its internal Phase-Locked Loop (IPLL), which multiplies the input from either the external crystal (1–8 MHz) or internal RC oscillator. This frequency is fully supported across the -40°C to +105°C temperature range and enables deterministic execution of time-critical automotive control loops within the S9S12G192F0VLLR's S12 CPU12 core.
Does the S9S12G192F0VLLR support AEC-Q100 qualification?
Yes, the S9S12G192F0VLLR is qualified to AEC-Q100 Grade 2 standards (-40°C to +105°C), with full test documentation covering accelerated environmental stress, reliability, and electrical characterization. This qualification is explicitly stated in NXP's official ordering information appendix and applies to the VLLR package variant of the S9S12G192F0VLLR device.
How many CAN interfaces does the S9S12G192F0VLLR include?
The S9S12G192F0VLLR integrates one Controller Area Network (CAN) module - the MSCAN peripheral - compliant with ISO 11898-1:2003 and supporting bit rates up to 1 Mbit/s. It provides full CAN 2.0B protocol handling including identifier masking, message buffering, and automatic retransmission, as confirmed in Chapter 18 of the MC9S12G Family Reference Manual Rev.1.28.
What debug interface is supported by the S9S12G192F0VLLR?
The S9S12G192F0VLLR supports the Background Debug Mode (BDM) interface via the BKGD pin, enabling single-wire in-circuit debugging, flash programming, and real-time register inspection. This interface is implemented per the S12SBDMV1 module specification and requires no additional pins beyond BKGD and ground - a key feature confirmed in Chapter 7 of the reference manual.
Is the S9S12G192F0VLLR pin-compatible with other MC9S12G family members?
The S9S12G192F0VLLR shares the same 112-pin LQFP package and pinout with the S9S12G240F0VLLR and S9S12GA192F0VLLR variants, as documented in Section 1.8.8 and 1.8.9 of the MC9S12G Family Reference Manual.
