Product details
Overview
MC9S08SL8CTL from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 8 KB FLASH, 512 B RAM, and 22 GPIO pins. It integrates ADC (10-bit, 16-channel), dual analog comparators, SCI, SPI, I²C, SLIC (LIN 2.0/J2602), TPM timers, RTC, and single-wire background debug - designed for automotive body electronics and industrial control nodes.
For engineers reviewing the MC9S08SL8CTL datasheet, MC9S08SL8CTL pinout, MC9S08SL8CTL application, or MC9S08SL8CTL equivalent, key selection criteria include LIN protocol support, stop3-mode operation with ADC/ACMP active, internal clock source trimming accuracy (±2% over voltage/temp), and TSSOP-20 package compatibility with board space constraints.
Technical Context
The MC9S08SL8CTL implements the HCS08 CPU core running at up to 40 MHz, supporting 32 interrupt/reset sources and HC08 instruction set plus BGND. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmable internal reference (0.2% resolution, ±2% deviation over voltage and temperature), enabling bus frequencies from 2–20 MHz without external crystal.
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 handling. The ADC operates in stop3 mode with 2.5 μs conversion time and integrated temperature sensor and bandgap reference.

| Single-wire BDM | Background debug interface uses only BKGD/MS pin - no dedicated debug header required, saving board space and cost |
| On-chip security | Flash block protection and memory security circuitry prevent unauthorized read-out of firmware and RAM contents |

FAQ
What is the maximum operating frequency of the MC9S08SL8CTL CPU core?
The MC9S08SL8CTL features an HCS08 CPU core rated for up to 40 MHz operation. Its actual bus frequency depends on the selected clock source configuration - typically 2–20 MHz when using the internal clock source (ICS) with FLL, or up to 40 MHz with external crystal oscillator. The core executes instructions at bus frequency, and all peripherals are synchronized to this clock domain.
Does the MC9S08SL8CTL include on-chip EEPROM memory?
No, the MC9S08SL8CTL does not integrate EEPROM. It contains 8 KB of on-chip FLASH memory (supporting read/program/erase during operation) and 512 bytes of RAM. Unlike higher-density variants such as MC9S08EL32, the MC9S08SL8CTL omits dedicated EEPROM - data logging or parameter storage must be implemented in FLASH with wear-leveling or external non-volatile memory.
Can the MC9S08SL8CTL operate in low-power modes while maintaining LIN communication?
Yes, the MC9S08SL8CTL supports LIN communication in stop3 mode via its dedicated SLIC module. In stop3, the SLIC remains fully active - handling automatic bit-rate synchronization, frame reception/transmission, and checksum verification - while CPU and most peripherals are halted. This enables ultra-low-power LIN slave operation with typical current draw below 2 μA.
What debugging interface does the MC9S08SL8CTL support?
The MC9S08SL8CTL supports a single-wire background debug mode (BDM) using the BKGD/MS pin. This interface enables in-circuit programming, breakpoint setting (one active breakpoint), and real-time register/memory inspection without requiring additional debug pins or headers. It is compatible with standard Freescale/NXP BDM debug tools including the DEMO9S08SL16 evaluation board and USB-based BDM interfaces.
Is the MC9S08SL8CTL pin-compatible with other devices in the HCS08 SL-series?
Yes, the MC9S08SL8CTL in TSSOP-20 package is pin-compatible with MC9S08SL16CTL and MC9S08SL32CTL. All share identical pin assignments, electrical characteristics, and peripheral mappings - allowing direct substitution where FLASH size requirements permit. This compatibility simplifies design reuse and migration across firmware complexity tiers within the same hardware platform.
