Product details
Overview
MC9S08SH16MTJ from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB flash, 1 KB RAM, and integrated ADC, ACMP, SCI, SPI, I²C, TPM, RTC, and background debug interface. It operates at up to 20 MHz bus frequency, supports multiple low-power stop/wait modes, and targets embedded control in industrial sensors and automotive body electronics.
For engineers reviewing the MC9S08SH16MTJ datasheet, MC9S08SH16MTJ pinout, MC9S08SH16MTJ application, or MC9S08SH16MTJ equivalent, key selection criteria include flash size, on-chip analog peripherals (10-bit ADC, analog comparator), real-time counter with 1 kHz internal oscillator, and TSSOP-28 package compatibility for space-constrained PCB layouts.
Technical Context
The MC9S08SH16MTJ implements the HCS08 CPU 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 enabling ±0.2% resolution and ±2% deviation over voltage/temperature.
Peripherals include a 16-channel 10-bit ADC with 2.5 μs conversion time and temperature sensor, dual 2-channel TPM modules supporting edge- or center-aligned PWM, and an 8-bit real-time counter (RTC) with external clock input or free-running 1 kHz internal oscillator - all functional in Stop3 mode.

FAQ
What is the maximum bus frequency supported by the MC9S08SH16MTJ?
The MC9S08SH16MTJ supports a maximum bus frequency of 20 MHz, enabled by its internal clock source (ICS) module with frequency-locked loop (FLL). This frequency is achievable using either the internal trimmed reference or an external crystal/resonator within specified ranges (1–16 MHz or 31.25–38.4 kHz), and remains stable across operating voltage and temperature per datasheet specifications.
Does the MC9S08SH16MTJ include hardware security features?
Yes, the MC9S08SH16MTJ includes on-chip security circuitry that prevents unauthorized access to both FLASH and RAM contents. This feature protects firmware intellectual property and calibration data from read-out attacks, and is configurable via FLASH protection registers (FPROT/NVPROT) during programming - a key requirement for certified automotive and medical applications.
Can the MC9S08SH16MTJ operate in ultra-low-power modes while maintaining real-time wake-up capability?
Yes, the MC9S08SH16MTJ supports Stop3 mode where the 8-bit real-time counter (RTC) continues running using its dedicated 1 kHz internal oscillator. This allows cyclic wake-up intervals (e.g., every 100 ms or 1 s) without external timing components, achieving sub-1 μA typical current draw - ideal for battery-powered sensor nodes requiring periodic measurement.
Which communication interfaces are integrated into the MC9S08SH16MTJ?
The MC9S08SH16MTJ integrates SCI (supporting LIN master/slave), SPI (full-duplex or single-wire, double-buffered), and I²C (up to 100 kbps, multi-master, 10-bit addressing). All three interfaces are accessible via dedicated pins in the TSSOP-28 package and support interrupt-driven operation, enabling robust peripheral connectivity in resource-constrained designs.
Is the MC9S08SH16MTJ pin-compatible with other members of the SH-series?
Yes, the MC9S08SH16MTJ shares identical pinout and package (28-TSSOP) with the MC9S08SH32MTJ and MC9S08SH8MTJ variants. This allows direct PCB reuse across flash-size variants - firmware can be scaled without layout changes, simplifying qualification and inventory management for families of related products.
