Product details
Overview
S9S08SG8E2MTGR 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 2–20 MHz bus frequencies. Used in automotive body electronics, industrial sensors, and battery-powered control modules.
For engineers reviewing the S9S08SG8E2MTGR datasheet, S9S08SG8E2MTGR pinout, S9S08SG8E2MTGR application, or S9S08SG8E2MTGR equivalent, key selection criteria include its 16-TSSOP package, -40°C to 125°C operating range, on-chip temperature sensor, real-time counter with 1 kHz oscillator, and single-wire background debug capability.
Technical Context
The S9S08SG8E2MTGR 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), enabling stable bus frequencies from 2 MHz to 20 MHz without external crystal.
Peripherals include a 12-channel 10-bit ADC (2.5 µs conversion, runs in stop3), dual analog comparators with bandgap reference and TPM routing, full-duplex SCI with LIN break support, and two 2-channel TPM modules supporting edge- or center-aligned PWM. All I/O pins feature configurable slew rate, drive strength, and hysteresis.

FAQ
What is the maximum operating temperature specification for the S9S08SG8E2MTGR?
The S9S08SG8E2MTGR is rated for operation from –40°C to +125°C. It is not qualified for the high-temperature 150°C variant-those devices use different part numbering (e.g., suffix 'H') and are only offered in 16-TSSOP. The S9S08SG8E2MTGR maintains full electrical performance and flash reliability across its specified industrial temperature range.
Does the S9S08SG8E2MTGR support in-circuit debugging without additional hardware?
Yes, the S9S08SG8E2MTGR supports single-wire background debug using only the BKGD/MS pin-no dedicated JTAG header or external debugger probe is required. This interface enables breakpoint setting, memory inspection, and real-time register access during active execution, and is fully supported by standard Freescale/NXP Codewarrior and S32DS toolchains.
Can the S9S08SG8E2MTGR's ADC operate while the MCU is in stop3 mode?
Yes, the ADC in the S9S08SG8E2MTGR remains fully functional in stop3 mode, including automatic compare, temperature sensor readings, and conversions triggered by internal or external events. This capability allows continuous sensor monitoring with ultra-low power consumption-critical for battery-operated applications where wake-up latency must be minimized.
What clock sources are available for the S9S08SG8E2MTGR's real-time counter (RTC)?
The S9S08SG8E2MTGR's RTC can use either an external clock source (e.g., 32.768 kHz crystal) or the internal low-power oscillator (1 kHz, ±10% tolerance). The internal oscillator runs independently in all MCU modes-including stop3-enabling cyclic wake-up without external components, which simplifies PCB layout and reduces BOM cost.
Is the S9S08SG8E2MTGR pin-compatible with other members of the SG8 family?
Yes, the S9S08SG8E2MTGR in 16-TSSOP is pin-compatible with the MC9S08SG4CTG and S9S08SG16E2MTGR in the same package. All share identical pin assignments, electrical characteristics, and peripheral mapping-allowing memory-size-based scalability without PCB redesign or firmware porting effort.
