Product details
Overview
S9S08SG4E2VTJ from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller designed for embedded control in automotive and industrial environments. It features a 40 MHz CPU, 4 KB flash memory, 512 B RAM, and operates across –40 °C to 125 °C. Integrated peripherals include 10-bit ADC, analog comparator, SCI, SPI, I²C, TPM PWM timers, and RTC - enabling use in motor control, body electronics, and sensor interface modules.
For engineers reviewing the S9S08SG4E2VTJ datasheet, S9S08SG4E2VTJ pinout, S9S08SG4E2VTJ application, or S9S08SG4E2VTJ equivalent, key selection criteria include its 16-pin TSSOP package, 2 MHz–20 MHz bus frequency range via internal clock source (ICS), stop3-mode operation with ADC/ACMP active, and single-wire background debug support for space-constrained designs.
Technical Context
The S9S08SG4E2VTJ implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference (±1.5% deviation over –40 °C to 125 °C) and supports bus frequencies from 2 MHz to 20 MHz.
Peripherals are optimized for low-power operation: ADC and ACMP remain functional in stop3 mode; RTC runs on a free-running 1 kHz on-chip oscillator; and COP watchdog can operate from dedicated 1 kHz internal clock. All I/O pins feature configurable pull-ups, slew rate, drive strength, and hysteresis.

FAQ
What is the maximum operating frequency of the S9S08SG4E2VTJ?
The S9S08SG4E2VTJ supports a maximum CPU frequency of 40 MHz at temperatures ≤125 °C. At higher ambient temperatures (up to 150 °C), the maximum bus frequency is reduced to 36 MHz to maintain timing margins and reliability. This derating is implemented in hardware and reflected in the device's electrical characteristics table per Freescale/NXP datasheet Rev. 8.
Does the S9S08SG4E2VTJ support LIN communication?
Yes, the S9S08SG4E2VTJ supports LIN 2.x communication via its SCI module, which includes hardware-assisted LIN master break generation and slave break detection. The SCI also provides wake-up on active edge, making it suitable for low-power LIN node implementations without external transceivers.
Can the S9S08SG4E2VTJ operate in stop mode with the ADC active?
Yes, the S9S08SG4E2VTJ supports ADC operation in stop3 mode - the deepest low-power state where the CPU and bus clocks are halted but selected peripherals (including ADC, ACMP, RTC, and COP) remain functional. This enables wake-up on analog threshold crossing or periodic sampling without full MCU restart.
What debug interface does the S9S08SG4E2VTJ use?
The S9S08SG4E2VTJ uses a single-wire background debug (BDM) interface compliant with the Freescale/NXP BDM specification. It supports in-circuit debugging, flash programming, and real-time trace via the BKGD/MS pin, with one hardware breakpoint and on-chip emulation capabilities including trigger-based flow capture.
Is the S9S08SG4E2VTJ qualified for automotive applications?
Yes, the S9S08SG4E2VTJ is AEC-Q100 qualified for Grade 2 (–40 °C to +105 °C) and Grade 1 (–40 °C to +125 °C) operation. Its design includes enhanced ESD protection, extended temperature validation, and failure-in-time (FIT) data aligned with automotive reliability standards - confirmed in the official NXP product change notices and qualification reports.
