Product details
Overview
MC9S08SH16CWL from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB Flash, 1 KB RAM, and a 40-MHz CPU core. It integrates ADC (10-bit, 16-channel), dual TPM PWM timers, SCI/SPI/IIC interfaces, RTC, and analog comparators - deployed in industrial sensor nodes and motor control subsystems.
For engineers reviewing the MC9S08SH16CWL datasheet, MC9S08SH16CWL pinout, MC9S08SH16CWL application, or MC9S08SH16CWL equivalent, this page delivers verified package mapping (28-TSSOP), validated peripheral timing behavior, confirmed stop3-mode operation for ADC/ACMP/RTC, and real-world selection guidance against functionally aligned alternatives.
Technical Context
The MC9S08SH16CWL implements the S08CPUV3 core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its ICS module delivers bus frequencies from 2 MHz to 20 MHz using FLL with internal reference trimmed to ±0.2% resolution.
Peripherals include two 2-channel TPM modules supporting input capture, output compare, and edge-/center-aligned PWM; a 10-bit ADC with 2.5 μs conversion time and temperature sensor; and ACMP with bandgap reference comparison and TPM routing capability - all operational in Stop3 mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08SH32CWL | Same package and pinout; doubles Flash (32 KB) and RAM (2 KB); identical peripheral set and clock architecture | Required where firmware complexity exceeds 16 KB or runtime data buffers exceed 1 KB | Select MC9S08SH32CWL when future firmware expansion headroom or larger data structures are needed - no PCB change required. |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+ core; 128 KB Flash, 16 KB RAM; higher performance but different toolchain, no HCS08 binary compatibility | Suitable for new designs needing >20 MHz deterministic execution or USB connectivity - not drop-in replacement | Choose S9KEAZ128AMLH only for greenfield projects prioritizing scalability over legacy code reuse. |
Compared with MC9S08SH32CWL, the MC9S08SH16CWL trades Flash/RAM capacity for lower unit cost and smaller footprint in fixed-function embedded roles; versus S9KEAZ128AMLH, it offers proven toolchain continuity and lower power in simple control loops but lacks ARM ecosystem features.

FAQ
What is the maximum operating frequency of the MC9S08SH16CWL CPU core?
The MC9S08SH16CWL features an HCS08 CPU core rated for up to 40 MHz operation. Its internal clock source (ICS) supports bus frequencies from 2 MHz to 20 MHz using the frequency-locked loop (FLL), with external crystal oscillator (XOSC) enabling full 40-MHz core execution when driven by a high-frequency crystal. This allows deterministic real-time response in motor control and sensor acquisition tasks executed by the MC9S08SH16CWL.
Does the MC9S08SH16CWL support analog-to-digital conversion with internal temperature sensing?
Yes, the MC9S08SH16CWL integrates a 16-channel, 10-bit ADC with 2.5 μs conversion time and includes a dedicated internal temperature sensor channel. It also provides an internal bandgap reference voltage (1.2 V) usable for both ADC and analog comparator (ACMP) operations - eliminating external reference components. This capability is fully retained in Stop3 mode, making the MC9S08SH16CWL ideal for battery-powered thermal monitoring.
Can the MC9S08SH16CWL operate in ultra-low-power modes while maintaining real-time wake-up capability?
Yes, the MC9S08SH16CWL supports Stop3 mode - its deepest power-saving state - where the RTC, ADC, ACMP, and COP watchdog remain fully operational. In this mode, typical current consumption drops below 1.5 μA while preserving the ability to wake on timer expiry, analog threshold crossing, or external interrupt. This behavior is documented and verified for the MC9S08SH16CWL across its full operating voltage and temperature range.
What debug interface does the MC9S08SH16CWL provide, and is external hardware required?
The MC9S08SH16CWL uses a single-wire background debug (BKGD) interface accessible via the BKGD/MS pin - requiring only one signal plus ground for full in-circuit programming and debugging. No external JTAG adapter is needed; standard tools like the NXP Multilink or OSJTAG cables connect directly. This interface supports breakpoint setting, memory inspection, and live register monitoring during active execution of the MC9S08SH16CWL.
Is the MC9S08SH16CWL pin-compatible with other devices in the SH-series, and which packages are supported?
Yes, the MC9S08SH16CWL is pin-compatible with the MC9S08SH32CWL in the same 28-TSSOP package (suffix "CWL"). Both share identical pin assignments, electrical characteristics, and peripheral mappings. The MC9S08SH16CWL is also offered in 28-SOIC, 20-TSSOP, and 16-TSSOP variants - with pin counts and functions scaled per package; full mechanical drawings and land patterns are specified in Freescale/NXP document S08SH32RM/AD.
