Product details
Overview
MC9S08SL16CTJ from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB flash, 1 KB RAM, and integrated LIN slave interface (SLIC), ADC, TPM, and I²C - designed for automotive body electronics and industrial control nodes requiring robust serial communication and low-power operation.
For engineers reviewing the MC9S08SL16CTJ datasheet, MC9S08SL16CTJ pinout, MC9S08SL16CTJ application, or MC9S08SL16CTJ equivalent, this page delivers verified specifications, package mapping to 20-pin TSSOP, functional role in LIN-based sensor/actuator nodes, and validated alternative options for migration or second sourcing.
Technical Context
The MC9S08SL16CTJ implements the HCS08 CPU core running at up to 40 MHz, with on-chip FLASH and EEPROM supporting in-circuit reprogramming and security lock. Its internal clock source (ICS) provides bus frequencies from 2–20 MHz using FLL with ±2% accuracy over voltage and temperature.
It integrates a dedicated Slave LIN Interface Controller (SLIC) compliant with LIN 2.0 and SAE J2602, enabling full message buffering, automatic checksum handling, and UART-like byte transfer - all operating independently of CPU intervention during LIN frame reception/transmission.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN slave microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08SL8CTJ | 8 KB FLASH, 512 B RAM, identical SLIC/ADC/TPM peripheral set and pinout. | Lower memory capacity limits firmware complexity; suitable for simpler LIN endpoints with minimal logic or calibration storage. | Select when application requires <8 KB code space and cost reduction is prioritized over future firmware scalability. |

FAQ
What is the maximum bus frequency supported by the MC9S08SL16CTJ?
The MC9S08SL16CTJ supports a maximum bus frequency of 20 MHz, achieved via its internal clock source (ICS) with frequency-locked loop (FLL). This is derived from either an internal trimmed reference (±2% accuracy over voltage and temperature) or an external crystal/resonator. The HCS08 CPU core operates at up to 40 MHz, with instruction execution tied to this bus clock.
Does the MC9S08SL16CTJ include hardware LIN protocol support?
Yes, the MC9S08SL16CTJ integrates a dedicated Slave LIN Interface Controller (SLIC) compliant with LIN 2.0 and SAE J2602. It handles full LIN frame reception/transmission, automatic checksum generation/verification, bit-rate synchronization, and message buffering - all without CPU intervention, reducing firmware overhead significantly in LIN slave applications.
What package type and pin count does the MC9S08SL16CTJ use?
The MC9S08SL16CTJ uses a 20-pin Thin Shrink Small Outline Package (TSSOP) with 0.65 mm lead pitch. This RoHS-compliant package is validated in Freescale's MC9S08EL32/SL16 Series Data Sheet Rev. 3 and supports compact PCB layouts common in automotive door modules and industrial control nodes.
Can the MC9S08SL16CTJ operate in ultra-low-power modes?
Yes, the MC9S08SL16CTJ supports two very low-power stop modes (Stop2 and Stop3), a reduced-power wait mode, and real-time interrupt wake-up. In Stop3 mode, current consumption drops below 10 µA while retaining RAM content and enabling wake-up via LIN message, RTC alarm, or external pin interrupt - ideal for battery-powered sensor nodes.
Is the MC9S08SL16CTJ pin-compatible with other HCS08 family members?
The MC9S08SL16CTJ shares the same 20-pin TSSOP footprint and core peripheral mapping with MC9S08SL8CTJ, enabling direct PCB reuse. However, it is not pin-compatible with 28-pin variants (e.g., MC9S08EL32) or devices with different I/O counts or peripheral allocations - pin compatibility must be verified per specific variant's pin assignment table in the official datasheet.
