Product details
Overview
S9S12G96F0MLL from NXP Semiconductors is a 16-bit automotive-grade microcontroller in the S12G family, featuring 96 KB on-chip Flash with ECC, 8 KB SRAM, and integrated CAN 2.0B controller. It operates at up to 25 MHz core frequency, supports -40°C to 125°C ambient temperature, and includes 10-bit ADC (8-channel), PWM (8-channel), and BDM debug interface. It is used in engine control units (ECUs) for real-time sensor signal acquisition and actuator drive logic.
For engineers reviewing the S9S12G96F0MLL datasheet, S9S12G96F0MLL pinout, S9S12G96F0MLL application, or S9S12G96F0MLL equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, CAN bus integration, Flash memory size and ECC support, operating temperature range, and compatibility with legacy S12 toolchains and development environments.
Technical Context
The S9S12G96F0MLL implements the CPU12 core with 16-bit data path and von Neumann architecture, executing instructions from internal Flash or external memory via expanded multiplexed bus mode. Its clock system combines internal RC oscillator (1 MHz), external crystal (1–32 MHz), and PLL for configurable system clock up to 50 MHz (with 2× divider for core).
Memory protection is enforced via background debug security lock and flash block write/erase enable registers. Peripheral modules-including MSCAN, ADC10B8CV2, TIM16B6CV3, and S12PWM8B8CV2-are memory-mapped and share interrupt vectors managed by the S12SINTV1 module with programmable priority levels.
