Product details
Overview
S9S08SG8E2MTG from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 8 KB flash, 512 B RAM, and integrated ADC, ACMP, SCI, SPI, I²C, TPM, RTC, and background debug interface. It operates at up to 40 MHz CPU frequency, supports stop3 low-power mode, and includes internal clock source with FLL for bus frequencies from 2–20 MHz. Used in automotive body electronics, industrial sensors, and appliance control.
For engineers reviewing the S9S08SG8E2MTG datasheet, S9S08SG8E2MTG pinout, S9S08SG8E2MTG application, or S9S08SG8E2MTG equivalent, key selection criteria include its 16-pin TSSOP package, -40°C to 125°C operating range, 10-bit 12-channel ADC with temperature sensor, real-time counter with 1 kHz low-power oscillator, and single-wire background debug capability.
Technical Context
The S9S08SG8E2MTG 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) trimmed for ±1.5% deviation over -40°C to 125°C, enabling stable bus frequencies from 2 MHz to 20 MHz without external crystal.
Peripherals include a 10-bit ADC with 2.5 µs conversion time and automatic compare, dual 2-channel TPM modules supporting edge- or center-aligned PWM, and an RTC with external clock input or free-running 1 kHz on-chip oscillator - all functional in stop3 mode. The SCI supports LIN master break generation and slave break detection.

FAQ
What is the maximum operating frequency of the S9S08SG8E2MTG at 125°C?
The S9S08SG8E2MTG operates at up to 36 MHz CPU frequency when ambient temperature exceeds 125°C, maintaining reliable execution while preserving flash endurance and timing margins. At lower temperatures (≤125°C), it supports up to 40 MHz. This derating ensures stable performance across its full qualified temperature range of -40°C to +125°C.
Does the S9S08SG8E2MTG support LIN communication natively?
Yes, the S9S08SG8E2MTG's SCI module supports LIN 2.0-compliant communication through dedicated hardware features: extended break generation in master mode and extended break detection in slave mode. These capabilities are implemented in silicon and require no additional external components or bit-banging firmware overhead.
Can the S9S08SG8E2MTG retain peripheral operation during low-power modes?
Yes, the S9S08SG8E2MTG maintains functionality of key peripherals in stop3 mode, including the RTC, ADC, and ACMP. This allows continuous temperature monitoring, timed wake-up events, and analog threshold detection while consuming microamp-level current - critical for battery-powered or energy-efficient applications.
What debug interface does the S9S08SG8E2MTG use, and what are its capabilities?
The S9S08SG8E2MTG uses a single-wire background debug (BDM) interface compliant with Freescale/NXP BDM specification. It supports in-circuit debugging with one hardware breakpoint, on-chip emulation (ICE) with eight-deep FIFO for flow tracing, and tag/force breakpoint modes - all accessible via standard BDM pod or compatible debug probes.
Is the S9S08SG8E2MTG pin-compatible with other members of the SG8 family?
Yes, the S9S08SG8E2MTG in 16-pin TSSOP is pin-compatible with MC9S08SG4E2MTG and S9S08SG16E2MTG. All share identical pin assignments, electrical characteristics, and peripheral mapping - enabling memory-size scalability without PCB layout changes.
