Product details
Overview
S9S08RN16W2MTJ 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, operating across –40 °C to 125 °C for engine control, body electronics, and sensor interface applications.
For engineers reviewing the S9S08RN16W2MTJ datasheet, S9S08RN16W2MTJ pinout, S9S08RN16W2MTJ application, or S9S08RN16W2MTJ equivalent, this page delivers verified electrical specs, validated peripheral timing, thermal resistance data for 20-pin TSSOP, and confirmed alternative MCUs for functional migration in harsh-environment embedded designs.
Technical Context
The S9S08RN16W2MTJ 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 ICS clock system integrates a frequency-locked loop (FLL) with factory-trimmed internal reference, delivering ±2% DCO output deviation over –40 °C to 125 °C.
System protection includes independent watchdog timer, low-voltage detection with configurable trip points (VLVDH = 4.2–4.4 V, VLVDL = 2.56–2.66 V), illegal opcode/address detection, and flash/RAM access protection - all qualified per AEC-Q100 Grade 1 requirements.
