Product details
Overview
MC9S08SL16CTL from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller designed for cost-sensitive automotive and industrial LIN node applications. It features 16 KB flash, 1 KB RAM, a 10-bit ADC with temperature sensor, dual analog comparators, SLIC (Slave LIN Interface Controller), and operates at up to 20 MHz bus frequency in a 28-pin TSSOP package.
For engineers reviewing the MC9S08SL16CTL datasheet, MC9S08SL16CTL pinout, MC9S08SL16CTL application, or MC9S08SL16CTL equivalent, key selection criteria include LIN 2.0/SLSAE J2602 compliance, stop3-mode operation with peripheral wake-up capability, integrated SLIC with automatic checksum handling, and single-wire background debug support for space-constrained embedded control designs.
Technical Context
The MC9S08SL16CTL implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) includes a frequency-locked loop (FLL) with precision-trimmed internal reference enabling ±0.2% resolution and ≤2% deviation over voltage and temperature.
Peripherals are optimized for LIN slave functionality: SLIC supports full LIN message buffering, automatic bit-rate synchronization, and UART-like byte transfer mode; ADC runs in stop3 mode with internal bandgap reference and temperature sensor; two ACMPs route outputs to TPM for event-triggered PWM control.

FAQ
What is the maximum bus frequency supported by the MC9S08SL16CTL?
The MC9S08SL16CTL supports a maximum bus frequency of 20 MHz, achieved via its internal clock source (ICS) with frequency-locked loop (FLL). This frequency is maintained across the full operating voltage (2.7–5.5 V) and temperature (−40°C to 105°C) range when using the trimmed internal reference or an external crystal source.
Does the MC9S08SL16CTL support LIN 2.0 protocol natively?
Yes, the MC9S08SL16CTL includes a dedicated Slave LIN Interface Controller (SLIC) that fully supports LIN 2.0 and SAE J2602 protocols. It handles automatic bit-rate detection, frame synchronization, checksum generation and verification, and extended break detection - all in hardware without CPU intervention.
Can the MC9S08SL16CTL operate in low-power modes while maintaining peripheral functionality?
Yes, the MC9S08SL16CTL supports stop3 mode, where the ADC, analog comparators, SLIC, RTC, and TPM modules remain fully operational. This allows wake-up on LIN activity, analog threshold crossing, or RTC timeout while consuming less than 10 µA - critical for battery-powered LIN nodes.
What debug interface does the MC9S08SL16CTL provide?
The MC9S08SL16CTL features a single-wire background debug interface compliant with the HCS08 standard. It supports in-circuit debugging with one hardware breakpoint, plus two additional breakpoints in the on-chip debug module, and includes an eight-deep FIFO for trace data capture during development.
Is the MC9S08SL16CTL pin-compatible with other devices in the HCS08 SL-series?
Yes, the MC9S08SL16CTL in 28-TSSOP is pin-compatible with MC9S08SL8CTL and MC9S08SL32CTL within the same package variant. All share identical pin assignments for power, reset, BKGD, oscillator, and peripheral I/O - enabling scalable memory upgrades without PCB redesign.
