Product details
Overview
MC9S08SH16CTLR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip FLASH, 1 KB RAM, and a 40-MHz CPU core. It integrates ADC (10-bit, 16-channel), dual TPM PWM modules, SCI/LIN, SPI, I²C, RTC, and ACMP - all operating in Stop3 mode. Designed for cost-sensitive industrial control and automotive body electronics.
For engineers reviewing the MC9S08SH16CTLR datasheet, MC9S08SH16CTLR pinout, MC9S08SH16CTLR application, or MC9S08SH16CTLR equivalent, key selection criteria include FLASH size (16 KB), stop-mode peripheral operation (ADC/ACMP/RTC active in Stop3), ICS clock accuracy (±2% over voltage/temp), and TSSOP-28 packaging for compact PCB layouts.
Technical Context
The MC9S08SH16CTLR implements the HCS08 CPUV3 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 and temperature), enabling bus frequencies from 2 MHz to 20 MHz.
Peripherals are architected for ultra-low-power operation: ADC and ACMP remain functional in Stop3 mode; RTC runs continuously on a dedicated 1-kHz internal oscillator; COP watchdog can operate from either bus clock or that same 1-kHz source. Memory protection includes FLASH block lock and security circuitry preventing unauthorized access to FLASH and RAM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | HCS08 CPUV3, 40-MHz max operation - enables deterministic real-time control at sub-25 ns instruction cycle time |
| FLASH Memory | 16 KB - sufficient for firmware with LIN stack, sensor processing, and EEPROM emulation |
| RAM | 1 KB - supports moderate variable allocation and stack depth for nested interrupts |
| ADC | 10-bit, 16-channel, 2.5 µs conversion - suitable for fast analog monitoring (e.g., battery voltage, thermistor, potentiometer) |
| RTC | 8-bit modulus counter with binary/decimal prescaler + 1-kHz internal oscillator - provides wake-up timing without external crystal |
| Stop3 Mode Current | Typical 2.5 µA - enables multi-year battery life in intermittently active sensor nodes |
| I²C Speed | Up to 100 kbps - compatible with standard-mode I²C peripherals (EEPROM, temp sensors, IO expanders) |
Pinout & Package
MC9S08SH16CTLR is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP) with 0.65 mm pitch, optimized for automated assembly and space-constrained industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power domains: VDD (core/analog I/O), VSS (digital/analog ground) - require separate low-impedance routing to minimize noise coupling |
| XTAL, EXTAL | Crystal/resonator interface | Supports 31.25 kHz–38.4 kHz or 1–16 MHz crystals - enables precise timing or low-cost RC-less clocking |
| BKGD/MS | Single-wire debug and mode select | Enables in-circuit debugging via BDM interface using only one pin - reduces test point count and layout complexity |
| PTA0–PTA7 | Port A general-purpose I/O | 8-bit port with configurable pull-ups, slew rate, and drive strength - supports ganged writes and edge-triggered interrupts |
| PTB0–PTB7 | Port B general-purpose I/O | Includes TPM1/TPM2 channel pins and SCI/SPI/I²C functions - allows flexible peripheral mapping without pin conflict |
| PTC0–PTC7 | Port C general-purpose I/O | Features ACMP inputs, ADC channels, and RTC input - enables mixed-signal signal routing with minimal external components |
Key Features
| Feature | Design Value |
|---|---|
| Stop3-mode peripheral operation | ADC, ACMP, RTC, and COP remain active during deepest low-power state - eliminates need for external wake-up circuitry |
| Internal Clock Source (ICS) | FLL-based clock generation with ±2% accuracy over full voltage/temperature range - removes dependency on external crystal for non-precision timing |
| On-chip security circuitry | Prevents unauthorized read-out of FLASH and RAM contents - protects firmware IP in production units |
| Background debug interface (BDM) | Single-wire, non-intrusive debugging with breakpoint support - enables field firmware updates and diagnostics without JTAG header |
| Ganged output capability | Simultaneous write to PTB[5:2] or PTC[3:0] - simplifies LED matrix or relay bank control with atomic register update |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08SH16CTJR | Same die, SOIC-28 package (vs. TSSOP-28); identical electrical specs and pinout mapping | Better thermal dissipation and hand-solderability; larger footprint | Select when manual assembly, higher ambient temperature, or legacy SOIC compatibility required |
| MC9S08SH32CTLR | Same package and pinout; doubles FLASH (32 KB) and RAM (2 KB); otherwise identical peripheral set and timing | Supports larger firmware images (e.g., bootloader + dual-bank OTA, expanded communication stacks) | Select when future firmware growth headroom or field upgrade capability is mandatory |
Compared with S9S08SH16CTJR and MC9S08SH32CTLR, the MC9S08SH16CTLR delivers optimal cost/performance balance for fixed-function embedded control where 16 KB FLASH suffices and TSSOP-28 footprint is preferred for high-density layouts.

FAQ
What is the maximum bus frequency supported by the MC9S08SH16CTLR?
The MC9S08SH16CTLR supports a maximum bus frequency of 20 MHz, achieved via its Internal Clock Source (ICS) module's frequency-locked loop (FLL). This frequency is sustained across the full operating voltage (2.7–5.5 V) and temperature (−40°C to +105°C) range when using the trimmed internal reference, enabling consistent real-time performance in demanding environments.
Does the MC9S08SH16CTLR support LIN communication?
Yes, the MC9S08SH16CTLR supports LIN 2.x communication through its Serial Communications Interface (SCI) module, which includes hardware-assisted LIN master break generation and LIN slave break detection. This allows the MC9S08SH16CTLR to serve as a certified LIN node without external transceivers beyond the physical layer driver.
Can the ADC in the MC9S08SH16CTLR operate during low-power stop modes?
Yes, the 10-bit ADC in the MC9S08SH16CTLR remains fully operational in Stop3 mode, including automatic compare, temperature sensor input, and internal bandgap reference channel. This capability enables periodic sensor sampling without waking the CPU, reducing system-level power consumption significantly.
What debug interface does the MC9S08SH16CTLR use?
The MC9S08SH16CTLR uses a single-wire Background Debug Mode (BDM) interface compliant with the Freescale/NXP BDM specification. It supports breakpoint setting, memory inspection, and register access during in-circuit debugging - all using only the BKGD/MS pin, minimizing PCB routing overhead.
Is the MC9S08SH16CTLR pin-compatible with the MC9S08SH32 series?
Yes, the MC9S08SH16CTLR is fully pin-compatible with the MC9S08SH32CTLR and other members of the SH32/SH16 family in the same package variant (e.g., TSSOP-28). They share identical pin assignments, electrical characteristics, and peripheral register maps - enabling direct hardware reuse when upgrading FLASH/RAM capacity.
