Product details
Overview
S9S08SG16E1CTJ from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip FLASH, 1 KB RAM, and integrated peripherals including 10-bit ADC, dual TPM timers, SCI, SPI, I²C, ACMP, RTC, and low-voltage detection. It operates at up to 40 MHz bus frequency, supports stop3 mode for ultra-low-power operation, and targets automotive body electronics and industrial control applications.
For engineers reviewing the S9S08SG16E1CTJ datasheet, S9S08SG16E1CTJ pinout, S9S08SG16E1CTJ application, or S9S08SG16E1CTJ equivalent, key selection criteria include its 16-TSSOP package, -40°C to +125°C temperature grade, 22 GPIOs with configurable slew rate and pull-ups, single-wire background debug interface, and FLASH block protection for secure firmware deployment.
Technical Context
The S9S08SG16E1CTJ implements the HCS08 CPU core with HC08 instruction set compatibility, BGND support, and up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference enabling ±1.5% frequency deviation over –40°C to +125°C.
Peripherals include a 16-channel 10-bit ADC with 2.5 µs conversion time and internal temperature sensor, two 2-channel TPM modules supporting input capture/output compare/PWM, and real-time counter (RTC) with free-running 1 kHz low-power oscillator that operates in all MCU modes including stop3.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08SG32E1CTJ | 32 KB FLASH, identical peripheral set and pinout; same 16-TSSOP package and temperature grade | Supports larger firmware images and more complex state machines without hardware redesign | Select when future firmware growth or feature expansion is anticipated |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+ core, 128 KB FLASH, 16 KB RAM, higher performance but different architecture and toolchain | Requires migration from HCS08 assembly/C to ARM GCC/Keil; not drop-in compatible | Choose for new designs needing higher throughput, USB, or CAN, accepting architectural change |
Compared with MC9S08SG32E1CTJ, the S9S08SG16E1CTJ offers identical I/O, timing, and debug capabilities in the same footprint but with half the FLASH - ideal for cost-optimized implementations where code size is constrained. Versus S9KEAZ128AMLH, it avoids ARM migration complexity while delivering proven reliability in legacy automotive platforms.

FAQ
What is the maximum bus frequency supported by the S9S08SG16E1CTJ?
The S9S08SG16E1CTJ supports a maximum bus frequency of 40 MHz when operating within its specified voltage and temperature range. This frequency is achieved using the internal clock source (ICS) with FLL enabled and properly configured. At temperatures above 125°C, the maximum bus frequency is reduced to 36 MHz to maintain timing integrity and reliability across the extended operating range of the S9S08SG16E1CTJ.
Does the S9S08SG16E1CTJ support LIN communication?
Yes, the S9S08SG16E1CTJ supports LIN communication through its Serial Communications Interface (SCI) module, which includes dedicated hardware features for LIN protocol implementation. Specifically, the SCI provides master-mode extended break generation and slave-mode extended break detection, enabling direct compliance with LIN 2.x specifications without additional external components or bit-banging overhead - a key capability confirmed in the official MC9S08SG32/SG16 datasheet revision 8.
What debug interface does the S9S08SG16E1CTJ use, and is external hardware required?
The S9S08SG16E1CTJ uses a single-wire background debug (BDM) interface accessible via the BKGD/MS pin. No external debug probe is strictly required for basic programming and debugging - a simple level-shifting circuit can connect directly to a UART-to-USB adapter. However, for full-featured in-circuit emulation (ICE), breakpoint management, and trace capabilities, NXP's OSBDM or third-party BDM-compatible debuggers are recommended to fully leverage the on-chip debug module in the S9S08SG16E1CTJ.
Can the S9S08SG16E1CTJ operate in ultra-low-power modes with peripherals active?
Yes, the S9S08SG16E1CTJ supports Stop3 mode - an ultra-low-power state where the CPU, bus clock, and most peripherals are disabled while retaining RAM and register contents. In this mode, the real-time counter (RTC) and analog comparator (ACMP) remain functional and can generate interrupts to wake the device. This capability allows the S9S08SG16E1CTJ to achieve sub-microamp quiescent current while maintaining responsiveness to time-based or analog events.
Is the S9S08SG16E1CTJ pin-compatible with other members of the MC9S08SGxx family?
Yes, the S9S08SG16E1CTJ is pin-compatible with the MC9S08SG32E1CTJ and other 16-pin TSSOP variants in the SGxx family, including identical pin assignments for VDD, VSS, RESET, BKGD/MS, XOSC/XFC, and all port pins (PTA0–PTA3, PTB0–PTB5, PTC0–PTC3). This allows direct substitution in existing PCB layouts when migrating between 16 KB and 32 KB FLASH variants, provided firmware accommodates memory map differences - a documented compatibility confirmed in Freescale's MC9S08SG32/SG16 datasheet revision 8.
