Product details
Overview
S9S08SL16F1MTL from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip FLASH, 1 KB RAM, and integrated LIN 2.0/SAE J2602 slave interface - used in automotive body electronics for door modules, seat controllers, and lighting nodes requiring low-power, protocol-compliant communication.
For engineers reviewing the S9S08SL16F1MTL datasheet, S9S08SL16F1MTL pinout, S9S08SL16F1MTL application, or S9S08SL16F1MTL equivalent, key selection criteria include its 20-pin TSSOP package, 2–20 MHz bus frequency range, stop3-mode operation with ADC/ACMP/SLIC active, and single-wire background debug support.
Technical Context
The S9S08SL16F1MTL 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, ±2% deviation over voltage/temperature), enabling stable bus frequencies from 2–20 MHz.
Peripherals include a 16-channel 10-bit ADC (2.5 μs conversion, runs in stop3), two analog comparators with bandgap reference option, and a dedicated Slave LIN Interface Controller (SLIC) supporting automatic bit-rate synchronization, checksum generation/verification, and full LIN message buffering at up to 120 kbps.

FAQ
What is the maximum bus frequency supported by the S9S08SL16F1MTL?
The S9S08SL16F1MTL supports a maximum bus frequency of 20 MHz, achieved via its internal clock source (ICS) with frequency-locked loop (FLL) and factory-trimmed internal reference. This frequency is fully operational across the device's rated temperature range (−40°C to 105°C) and supply voltage (2.7–5.5 V), enabling deterministic real-time response for LIN protocol timing and peripheral servicing.
Does the S9S08SL16F1MTL support LIN 2.0 and SAE J2602 protocols simultaneously?
Yes, the S9S08SL16F1MTL's Slave LIN Interface Controller (SLIC) natively supports both LIN 2.0 and SAE J2602 standards. It performs automatic bit-rate detection, frame synchronization, checksum generation/verification, and full message buffering - allowing seamless interoperability with masters implementing either specification without firmware modification.
Can the S9S08SL16F1MTL operate in low-power modes while maintaining LIN communication capability?
Yes, the S9S08SL16F1MTL supports stop3 mode, where the CPU and most peripherals halt but the SLIC, ADC, and analog comparators remain active. This enables continuous LIN header detection and wake-up on valid message reception - critical for battery-powered automotive nodes requiring ultra-low quiescent current (<10 µA typical).
What debug interface does the S9S08SL16F1MTL provide, and what are its capabilities?
The S9S08SL16F1MTL features a single-wire background debug (BDM) interface on the BKGD/MS pin. It supports in-circuit debugging with one hardware breakpoint, real-time register/memory inspection, and flash programming - all using a single signal line and standard BDM protocol, simplifying test fixture design and reducing PCB routing complexity.
Is the S9S08SL16F1MTL pin-compatible with other members of the MC9S08SLxx family?
Yes, the S9S08SL16F1MTL in 20-pin TSSOP is pin-compatible with MC9S08SL8F1MTL and shares identical peripheral mapping, register layout, and electrical characteristics. Firmware developed for one can run unmodified on the other, differing only in FLASH/RAM capacity - enabling scalable design reuse across product variants.
