Product details
Overview
S9S08SG16E1WTG from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip FLASH, 1 KB RAM, and integrated peripherals including 10-bit ADC, dual TPM timers, SCI, SPI, I²C, ACMP, and RTC. It operates at up to 40 MHz bus frequency, supports -40°C to 125°C temperature range, and targets low-power embedded control in automotive body electronics and industrial sensors.
For engineers reviewing the S9S08SG16E1WTG datasheet, S9S08SG16E1WTG pinout, S9S08SG16E1WTG application, or S9S08SG16E1WTG equivalent, key selection criteria include FLASH size (16 KB), TSSOP-16 package compatibility, stop3-mode operation for ultra-low-power wake-up, internal clock source (ICS) trimming accuracy (±1.5% over -40°C to 125°C), and LIN-capable SCI interface support.
Technical Context
The S9S08SG16E1WTG implements the HCS08 CPU core with BGND instruction support, 36 interrupt/reset sources, and a memory-mapped peripheral architecture. Its ICS module integrates a frequency-locked loop (FLL) with internal reference trimming, enabling stable 2–20 MHz bus frequencies without external crystal in many applications.
Peripherals include a 16-channel 10-bit ADC with 2.5 µs conversion time and internal temperature sensor, two 2-channel TPM modules supporting PWM and input capture, and a real-time counter (RTC) with free-running 1 kHz low-power oscillator - all functional in stop3 mode. The device uses SuperFlash® technology for reliable FLASH endurance and security features including block protection and background debug interface lock.

FAQ
What is the maximum operating temperature specification for the S9S08SG16E1WTG?
The S9S08SG16E1WTG is rated for operation from -40°C to +125°C ambient temperature and is qualified to AEC-Q100 Grade 2 standards. This makes it suitable for under-hood automotive applications and industrial environments with elevated thermal stress. The device maintains full functionality across this range, including FLASH programming, ADC accuracy, and ICS frequency stability.
Does the S9S08SG16E1WTG support LIN communication natively?
Yes, the S9S08SG16E1WTG supports LIN 2.0/2.1 communication through its SCI1 module, which includes dedicated hardware for LIN master break generation and LIN slave break detection. This enables direct integration into automotive LIN networks without external transceivers for basic node functions, though a LIN physical layer transceiver is still required for bus interfacing.
What power-saving modes are available on the S9S08SG16E1WTG?
The S9S08SG16E1WTG supports Run, Wait, Stop2, and Stop3 modes. Stop3 is the deepest low-power state, drawing less than 1 µA while keeping the RTC, ACMP, and selected ADC channels operational for wake-up event detection. This mode is critical for battery-powered applications requiring long standby life with periodic sensor polling or external interrupt response.
Is the S9S08SG16E1WTG pin-compatible with other members of the SG-series?
Yes, the S9S08SG16E1WTG is pin-compatible with the S9S08SG32E1WTG in the 16-pin TSSOP package. Both share identical pin assignments, electrical characteristics, and peripheral mapping. This allows seamless migration between 16 KB and 32 KB FLASH variants without PCB redesign, provided the application firmware fits within the smaller memory footprint.
What debugging interface does the S9S08SG16E1WTG use?
The S9S08SG16E1WTG uses a single-wire background debug (BDM) interface via the BKGD/MS pin. This interface supports in-circuit debugging, flash programming, breakpoint setting, and real-time register inspection using standard Freescale/NXP BDM tools such as the Multilink Universal or OSJTAG adapters. No additional debug headers or pins are required.
