Product details
Overview
S9S08SL16F1MTJ from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB flash, 1 KB RAM, and integrated LIN 2.0/SAE J2602 slave interface. It features a 40-MHz CPU, 10-bit ADC with temperature sensor, two analog comparators, and real-time counter. Used in automotive body electronics for LIN node control.
For engineers reviewing the S9S08SL16F1MTJ datasheet, S9S08SL16F1MTJ pinout, S9S08SL16F1MTJ application, or S9S08SL16F1MTJ equivalent, key selection criteria include LIN protocol compliance, 20-TSSOP package compatibility, stop3-mode operation with peripheral wake-up, and on-chip EEPROM programmability during flash execution.
Technical Context
The S9S08SL16F1MTJ 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 (±0.2% resolution, ±2% deviation over voltage/temperature), enabling bus frequencies from 2–20 MHz.
Peripherals include a dedicated Slave LIN Interface Controller (SLIC) compliant with LIN 2.0 and SAE J2602, supporting up to 120 kbps, full message buffering, automatic bit-rate synchronization, and checksum generation/verification. The ADC operates in stop3 mode with 2.5 μs conversion time and internal bandgap reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN slave microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08SL8F1MTJ | 8 KB flash, 512 B RAM, identical peripheral set and pinout; lower memory density | Same automotive LIN slave use cases where firmware footprint ≤8 KB suffices | Select when application code and data fit within reduced memory, enabling cost optimization without redesign |
| S9S08SG16E1MTJ | Same 16 KB flash/RAM but adds SPI and enhanced I²C; no SLIC - requires external LIN transceiver | Applications needing SPI connectivity (e.g., EEPROM, display driver) and willing to add discrete LIN PHY | Choose when system-level flexibility outweighs integration benefit, and board space allows external transceiver |
Compared with MC9S08SL8F1MTJ and S9S08SG16E1MTJ, the S9S08SL16F1MTJ uniquely balances LIN protocol offload, memory headroom, and 20-TSSOP footprint - making it optimal for cost-constrained, space-limited automotive nodes requiring zero-software LIN stack overhead.

FAQ
What is the maximum bus frequency supported by the S9S08SL16F1MTJ?
The S9S08SL16F1MTJ supports a maximum bus frequency of 20 MHz, achieved via its internal clock source (ICS) with frequency-locked loop (FLL). This is confirmed in the MC9S08EL32 Series and MC9S08SL16 Series Data Sheet Rev. 3, Section 8.1.2, which specifies 2–20 MHz operation under full temperature and voltage ranges. The S9S08SL16F1MTJ maintains timing integrity at this rate due to precision internal reference trimming.
Does the S9S08SL16F1MTJ include a hardware LIN interface?
Yes, the S9S08SL16F1MTJ integrates a dedicated Slave LIN Interface Controller (SLIC) compliant with LIN 2.0 and SAE J2602 standards. As documented in Chapter 12 of the datasheet, the SLIC handles bit-rate synchronization, checksum generation/verification, and full message buffering - eliminating software protocol stack overhead. This hardware LIN interface is a defining feature of the S9S08SL16F1MTJ.
Can the S9S08SL16F1MTJ operate in low-power stop modes while maintaining peripheral functionality?
Yes, the S9S08SL16F1MTJ supports stop3 mode, where the ADC, analog comparators, real-time counter (RTC), and SLIC remain fully operational and capable of generating wake-up interrupts. Per Section 3.6.1 and Chapter 10 of the datasheet, ADC conversions and SLIC frame reception continue autonomously during stop3, enabling responsive low-power operation without CPU intervention - a key capability of the S9S08SL16F1MTJ.
What package type does the S9S08SL16F1MTJ use, and is it RoHS-compliant?
The S9S08SL16F1MTJ uses a 20-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm lead pitch, as specified in Appendix B of the MC9S08EL32 Series datasheet. All variants bearing the "MTJ" suffix, including the S9S08SL16F1MTJ, are RoHS-compliant and halogen-free per NXP's product change notices and packaging specifications dated 2008 onward.
Is on-chip EEPROM available in the S9S08SL16F1MTJ, and can it be programmed during flash execution?
Yes, the S9S08SL16F1MTJ includes in-circuit programmable EEPROM with erase-abort capability. Crucially, the datasheet (Section 4.5.10) confirms that EEPROM can be programmed and erased while the CPU executes code from flash memory - enabling runtime data logging, calibration storage, and firmware update staging without halting application execution. This dual-operation capability is a verified feature of the S9S08SL16F1MTJ.
