Product details
Overview
S9S08SG4E2MTJR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 4 KB flash, 256 B RAM, and integrated ADC, ACMP, SCI, SPI, I²C, TPM, and RTC peripherals. It operates at up to 40 MHz CPU frequency, supports stop3 low-power mode, and includes single-wire background debug interface. Used in automotive body electronics and industrial sensor nodes requiring compact, cost-optimized MCU control.
For engineers reviewing the S9S08SG4E2MTJR datasheet, S9S08SG4E2MTJR pinout, S9S08SG4E2MTJR application, or S9S08SG4E2MTJR equivalent, key selection criteria include flash endurance over temperature, real-time interrupt capability in stop3 mode, internal clock source accuracy (±1.5% over –40°C to 125°C), and compatibility with legacy HCS08 toolchains and debug infrastructure.
Technical Context
The S9S08SG4E2MTJR 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 for bus frequencies from 2 MHz to 20 MHz.
Peripherals include a 12-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 RTC with 1 kHz on-chip oscillator enabling cyclic wake-up in all power modes.
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 |
|---|---|---|---|
| MC9S08SG8CDT | 8 KB flash, 512 B RAM, identical peripheral set and pinout; higher memory density but same 16-TSSOP package | Preferred where firmware growth headroom or bootloader partitioning is required | Select when future firmware expansion is anticipated without changing PCB layout |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+ core, 128 KB flash, 16 KB RAM, enhanced ADC (16-bit), no HCS08 code compatibility | Targeting next-generation designs needing higher performance, RTOS support, or advanced connectivity | Choose for new designs prioritizing scalability over legacy toolchain reuse |
Compared with MC9S08SG8CDT, S9S08SG4E2MTJR offers sufficient memory for basic control tasks with lower cost and smaller footprint; versus S9KEAZ128AMLH, it provides proven HCS08 ecosystem compatibility but lacks ARM-class throughput and peripheral depth.

FAQ
What is the maximum operating temperature rating for S9S08SG4E2MTJR?
The S9S08SG4E2MTJR is rated for operation from –40°C to 125°C. Unlike some variants in the SG8/SG4 family, it is not qualified for the extended 150°C high-temperature grade. Its ICS accuracy specification (±1.5%) applies across this full industrial temperature range, and flash endurance is guaranteed under these conditions.
Does S9S08SG4E2MTJR support in-circuit debugging via standard JTAG?
No, the S9S08SG4E2MTJR uses a proprietary single-wire background debug (BDM) interface, not JTAG. Debugging requires an NXP-compatible BDM pod (e.g., OSBDM or DEMO9S08SG8 board) and CodeWarrior Development Studio v6.3 or later. The BKGD/MS pin serves as the sole debug communication path.
Can S9S08SG4E2MTJR operate without an external crystal?
Yes, the S9S08SG4E2MTJR can run entirely from its internal clock source (ICS) with FLL enabled. The ICS provides bus frequencies from 2 MHz to 20 MHz and maintains ±1.5% accuracy over –40°C to 125°C, making external crystals optional for non-precision timing applications like motor control or sensor polling.
What power-saving modes are available on S9S08SG4E2MTJR, and which peripherals remain active in stop3 mode?
The S9S08SG4E2MTJR supports run, wait, stop2, and stop3 modes. In stop3, the RTC, ACMP, and ADC remain functional and can generate wake-up interrupts. The CPU, flash, and most clocks halt, reducing current draw to sub-1 µA. This enables ultra-low-power periodic sensing while retaining precise timekeeping and analog event detection.
Is S9S08SG4E2MTJR pin-compatible with MC9S08SG8 devices in the same package?
Yes, the S9S08SG4E2MTJR in 16-TSSOP is pin-compatible with MC9S08SG8CDT and other 16-pin SG8/SG4 variants. All share identical pin assignments, electrical characteristics, and peripheral mappings per the shared MC9S08SG8/SG4 datasheet Rev. 8, enabling direct substitution where flash/RAM requirements align.
