Product details
Overview
MC9S08SH16CTJ 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, ACMP, SCI, SPI, I²C, TPM, RTC, and low-power stop modes. Used in industrial sensor nodes and appliance control where compact code footprint and mixed-signal integration are critical.
For engineers reviewing the MC9S08SH16CTJ datasheet, MC9S08SH16CTJ pinout, MC9S08SH16CTJ application, or MC9S08SH16CTJ equivalent, key selection criteria include Flash size, peripheral set (especially dual TPM modules and stop3-capable ADC), TSSOP-28 package compatibility, and background debug interface support.
Technical Context
The MC9S08SH16CTJ implements the HCS08 CPUV3 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 include a 16-channel 10-bit ADC with 2.5 μs conversion time and temperature sensor, two 2-channel TPM modules supporting edge- or center-aligned PWM, and an SCI module with LIN master break generation. All major analog and timing peripherals remain functional in Stop3 mode.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08SH32CTJ | 32 KB Flash, same peripherals and pinout - identical architecture and register map | Required when firmware exceeds 16 KB or needs larger data buffers for communication protocols | Select MC9S08SH32CTJ only if additional Flash/RAM is confirmed necessary; otherwise MC9S08SH16CTJ reduces BOM cost |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+, 128 KB Flash, 16 KB RAM, different instruction set and peripheral registers | Suitable for new designs requiring higher performance, USB, or CAN; not drop-in compatible | Choose S9KEAZ128AMLH for future-proofing or scalability; migration requires full firmware rewrite and PCB layout review |
Compared with MC9S08SH32CTJ, the MC9S08SH16CTJ offers identical peripheral functionality and power behavior at lower Flash density and cost; versus S9KEAZ128AMLH, it provides proven 8-bit determinism and smaller code size but lacks ARM ecosystem tooling and advanced interfaces like USB or CAN.

FAQ
What is the maximum operating frequency of the MC9S08SH16CTJ?
The MC9S08SH16CTJ 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 FLL, with optional external crystal up to 16 MHz. The 40-MHz rating refers to core instruction execution speed under optimal conditions, not bus clock frequency.
Does the MC9S08SH16CTJ support in-circuit debugging?
Yes, the MC9S08SH16CTJ includes a single-wire background debug (BDM) interface compliant with Freescale/NXP BDM specification. It supports breakpoint setting, single-step execution, and memory/register inspection during live operation. The on-chip debug module provides two additional hardware breakpoints and an eight-deep FIFO for trace data capture.
Can the MC9S08SH16CTJ operate in ultra-low-power modes?
Yes, the MC9S08SH16CTJ supports three low-power modes: Wait, Stop2, and Stop3. Stop3 is the deepest, drawing sub-1 µA typical current while retaining RAM, RTC, and select peripherals including ADC, ACMP, and SCI. This enables wake-on-comparator event or RTC alarm without external components.
What analog peripherals are integrated into the MC9S08SH16CTJ?
The MC9S08SH16CTJ integrates a 16-channel 10-bit ADC with 2.5 µs conversion time, automatic compare function, and internal temperature sensor; two analog comparators (ACMP) with selectable interrupt edges and bandgap reference option; and dedicated analog power/ground pins (VDDAD/VSSAD) for noise isolation. All analog modules remain operational in Stop3 mode.
Is the MC9S08SH16CTJ pin-compatible with other devices in the SH-series?
Yes, the MC9S08SH16CTJ in 28-TSSOP package shares identical pinout with MC9S08SH32CTJ and MC9S08SH8CTJ per datasheet Rev. 3 Section 2.1. This allows hardware reuse across Flash variants. However, pin compatibility does not extend to non-SH-series HCS08 devices or Kinetis E-family MCUs due to differing peripheral mappings and signal assignments.
