Product details
Overview
S9S08SG16E1MTL 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 embedded control in automotive body electronics and industrial sensors.
For engineers reviewing the S9S08SG16E1MTL datasheet, S9S08SG16E1MTL pinout, S9S08SG16E1MTL application, or S9S08SG16E1MTL equivalent, key selection criteria include Flash size (16 KB), TSSOP-16 package, 22 GPIOs, stop3-mode low-power operation, and integrated LVD/LVW voltage monitoring for robust supply supervision.
Technical Context
The S9S08SG16E1MTL implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference (0.2% resolution), delivering bus frequencies from 2 MHz to 20 MHz across temperature.
Peripherals include a 16-channel 10-bit ADC with 2.5 µs conversion time and 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 enabling wake-up from all MCU modes without external components.

FAQ
What is the maximum operating temperature range for the S9S08SG16E1MTL?
The S9S08SG16E1MTL is rated for operation from -40°C to +125°C. This extended temperature range is validated per Freescale's high-temperature device specifications and supports deployment in under-hood automotive modules and industrial equipment with elevated ambient conditions. The S9S08SG16E1MTL maintains full functionality-including Flash programming, ADC accuracy, and RTC operation-across this entire range.
Does the S9S08SG16E1MTL support in-circuit debugging?
Yes, the S9S08SG16E1MTL supports single-wire background debug (BKGD) via the PTC2 pin. This interface enables full in-circuit emulation, flash programming, and breakpoint-based debugging without requiring additional pins or external debug probes beyond a compatible BDM tool. The S9S08SG16E1MTL includes an on-chip debug module with two comparators and nine trigger modes for advanced flow analysis.
Can the S9S08SG16E1MTL operate from a single 3.3 V supply?
Yes, the S9S08SG16E1MTL operates across a supply voltage range of 2.7 V to 5.5 V, making it fully compatible with 3.3 V systems. All I/O pins are 5 V tolerant when configured as inputs, and internal regulators ensure stable core voltage regardless of VDD within spec. The S9S08SG16E1MTL's ADC, RTC, and LVD functions remain fully specified at 3.3 V.
How many analog input channels does the S9S08SG16E1MTL ADC support?
The S9S08SG16E1MTL integrates a 10-bit successive-approximation ADC with 16 selectable analog input channels (AD0–AD15), mapped to dedicated port pins. All 16 channels are accessible simultaneously in software-controlled scan mode, and the ADC includes automatic comparison, temperature sensor input, and internal bandgap reference for self-calibration. Channel selection is performed via the ADSCR register in the S9S08SG16E1MTL.
Is the S9S08SG16E1MTL pin-compatible with other members of the MC9S08SGxx family?
Yes, the S9S08SG16E1MTL in the 16-pin TSSOP package shares identical pinout and electrical characteristics with the S9S08SG32E1MTL and S9S08SG8E1MTL variants. This allows direct substitution based on Flash size requirements without PCB redesign. All three share the same peripheral register map, memory layout, and debug interface behavior - the S9S08SG16E1MTL differs only in Flash capacity (16 KB vs. 32 KB or 8 KB).
