Product details
Overview
MC9S08SH32CTGR from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB on-chip FLASH, 1.5 KB RAM, and a 40-MHz CPU core. It integrates ADC (16-channel, 10-bit), dual TPM PWM modules, SCI/LIN, SPI, I²C, RTC, and analog comparators - designed for cost-sensitive embedded control in automotive body electronics and industrial sensors.
For engineers reviewing the MC9S08SH32CTGR datasheet, MC9S08SH32CTGR pinout, MC9S08SH32CTGR application, or MC9S08SH32CTGR equivalent, key selection criteria include its stop3-mode operation with ADC/ACMP active, 23 GPIOs with configurable slew/pull-up, and single-wire BDM debug interface for space-constrained designs.
Technical Context
The MC9S08SH32CTGR implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its internal clock source (ICS) delivers bus frequencies from 2 MHz to 20 MHz using FLL with ±0.2% trimming resolution and ±2% deviation over voltage/temperature.
Peripherals operate across power modes: ADC and ACMP remain functional in stop3 mode; RTC runs continuously via 1-kHz on-chip oscillator; SCI supports LIN master break generation and slave wake-up detection - enabling low-power sensor node and body-control applications without external timing components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | HCS08 8-bit core, 40-MHz max frequency - enables deterministic real-time control with sub-μs interrupt latency |
| FLASH Memory | 32 KB on-chip FLASH with block protection and full-voltage erase - supports field firmware updates without external programmer |
| RAM | 1.5 KB on-chip RAM with security lock - sufficient for RTOS stacks and sensor data buffering in compact nodes |
| ADC | 16-channel, 10-bit, 2.5 μs conversion time with temperature sensor and bandgap reference - enables direct thermal monitoring and analog signal acquisition in stop3 |
| Power Modes | Two very low-power stop modes (stop2/stop3), reduced-power wait mode - achieves <1 μA stop3 current for battery-backed systems |
| Debug Interface | Single-wire background debug (BDM) with one hardware breakpoint - allows in-circuit debugging with minimal PCB footprint and no JTAG header |
| Package | 28-pin TSSOP (CTGR suffix) - 9.7 × 4.4 mm body, 0.65 mm pitch, RoHS-compliant surface-mount package for high-density layouts |
Pinout & Package
MC9S08SH32CTGR is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP) with exposed pad, optimized for thermal performance and automated assembly. Pin functions are validated per Freescale MC9S08SH32 Rev. 3 datasheet Section 2.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual 2.7–5.5 V supply rails; separate analog/digital ground pins (VSSAD/VSS) reduce noise coupling into ADC |
| XTAL, EXTAL | Crystal oscillator inputs | Supports 31.25 kHz–38.4 kHz or 1–16 MHz crystals/resonators - enables precise timing or low-cost RC-free clocking |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; accepts external reset IC or manual pushbutton with debounce |
| BKGD/MS | Background debug / mode select | Single-wire BDM communication and boot-mode selection - eliminates need for dedicated debug header |
| PTA0–PTA7 | Port A general-purpose I/O | 8-bit port with interrupt capability, configurable pull-up/hysteresis, and ganged output option - simplifies LED/motor driver control logic |
| PTB0–PTB7 | Port B general-purpose I/O | 8-bit port including TPM1/TPM2 channel pins and SCI transmit/receive - supports PWM-driven actuators and serial comms simultaneously |
| PTC0–PTC7 | Port C general-purpose I/O | 7-bit port (PTC7 reserved) with ACMP/ADC inputs and I²C/SPI signals - enables mixed-signal peripheral routing without external muxing |
Key Features
| Feature | Design Value |
|---|---|
| Stop3-mode peripheral operation | ADC, ACMP, RTC, and SCI retain functionality during ultra-low-power stop3 - enables wake-on-analog-event sensing without CPU wake-up overhead |
| Internal clock source (ICS) | FLL-based ICS with ±0.2% trim resolution and internal temperature compensation - eliminates crystal for cost-sensitive applications while maintaining timing accuracy |
| On-chip security circuitry | FLASH/RAM read/write protection with security byte lock - prevents firmware reverse engineering and unauthorized memory access in production units |
| Integrated LIN physical layer support | SCI module provides LIN master break generation and slave break detection - reduces BOM by eliminating external LIN transceiver in body control modules |
| Ganged GPIO output | PTB[5:2] and PTC[3:0] support single-write multi-pin state change - accelerates LED array or segment display updates with minimal CPU cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08SG32F1MTJR | Same HCS08 core, identical 32 KB FLASH/1.5 KB RAM, but uses newer S08SG die with enhanced ESD rating (4 kV HBM) and updated I²C timing. | Preferred for new designs requiring AEC-Q100 Grade 2 qualification and improved robustness in automotive harness environments. | Select when higher ESD immunity and automotive qualification are mandatory; pinout and code compatibility preserved. |
| MC9RS08LA8CP | RS08 core (lower code density), 8 KB FLASH, no TPM modules, only 8-channel ADC - lacks PWM and LIN support. | Suitable for ultra-low-cost, non-motorized applications like simple remote controls or status indicators. | Choose only for cost-driven, functionally reduced replacements where PWM, LIN, and 16-channel ADC are unnecessary. |
Compared with MC9S08SH32CTGR, S9S08SG32F1MTJR offers drop-in compatibility with enhanced automotive robustness, while MC9RS08LA8CP sacrifices peripherals and memory for lower unit cost - making the former ideal for design refreshes and the latter viable only in stripped-down use cases.

FAQ
What is the maximum operating frequency of the MC9S08SH32CTGR CPU core?
The MC9S08SH32CTGR features an HCS08 CPU core rated for up to 40 MHz operation. This frequency is achievable when using the internal clock source (ICS) with FLL enabled and appropriate bus prescaling. The core maintains full instruction set compatibility and deterministic timing at this speed, supporting real-time control loops with sub-microsecond response in applications such as motor commutation and LIN protocol handling.
Does the MC9S08SH32CTGR support LIN communication natively?
Yes, the MC9S08SH32CTGR supports LIN communication through its integrated SCI module, which implements LIN master break generation and LIN slave extended break detection per LIN 2.1 specification. No external transceiver is required for basic LIN node functionality, though a physical-layer transceiver must still be used for bus connection. The MC9S08SH32CTGR handles protocol framing, checksum calculation, and wake-up detection in firmware.
What power modes does the MC9S08SH32CTGR support, and which peripherals remain active in stop3 mode?
The MC9S08SH32CTGR supports run, wait, stop2, and stop3 modes. In stop3 mode - its lowest-power state - the ADC, analog comparators (ACMP), real-time counter (RTC), and SCI module remain fully operational. This enables wake-up on analog threshold crossing, periodic RTC interrupts, or serial bus activity while drawing less than 1 μA, making the MC9S08SH32CTGR ideal for battery-powered sensing applications.
How many GPIO pins does the MC9S08SH32CTGR provide, and what configurability options are available?
The MC9S08SH32CTGR provides 23 general-purpose I/O pins and 1 output-only pin across Ports A, B, and C. Each input pin supports programmable hysteresis and pull-up devices; each output pin allows configuration of slew rate and drive strength. Additionally, PTB[5:2] and PTC[3:0] support ganged output - enabling simultaneous state changes across multiple pins with a single write - useful for LED arrays or display segments.
Is the MC9S08SH32CTGR pin-compatible with other members of the HCS08 SH-series?
The MC9S08SH32CTGR in 28-TSSOP (CTGR) is pin-compatible with MC9S08SH16CTGR and MC9S08SH8CTGR within the same package variant, sharing identical pin assignments and electrical characteristics. However, it is not compatible with 20-TSSOP or 16-TSSOP variants due to differing pin counts and layouts. Firmware built for MC9S08SH32CTGR will run unmodified on lower-memory SH variants if FLASH/RAM usage remains within their limits.
