Product details
Overview
S9S08SG4E2MSC 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, RTC, and background debug interface. It operates at up to 40 MHz CPU frequency, supports stop3 low-power mode, and targets automotive body electronics and industrial control applications requiring extended temperature operation.
For engineers reviewing the S9S08SG4E2MSC datasheet, S9S08SG4E2MSC pinout, S9S08SG4E2MSC application, or S9S08SG4E2MSC equivalent, key selection criteria include its 16-pin TSSOP package, -40°C to 125°C operating range, 10-bit 12-channel ADC with temperature sensor, single-wire BDM debug support, and real-time counter with on-chip 1 kHz oscillator for wake-up in all power modes.
Technical Context
The S9S08SG4E2MSC implements the HCS08 CPU core with HC08 instruction set extension (including BGND), supporting up to 32 interrupt/reset sources and a 3-stage pipeline. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference (±1.5% deviation over –40°C to 125°C) to generate bus frequencies from 2 MHz to 20 MHz.
Peripherals include a 10-bit ADC with 2.5 µs conversion time and automatic compare, dual analog comparators with bandgap reference option and TPM routing capability, full-duplex SCI with LIN break generation/detection, and two 2-channel TPM modules supporting input capture, output compare, and edge-/center-aligned PWM - all functional in stop3 mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08SG8CTJ | 8 KB flash, 512 B RAM, identical peripheral set and pinout in 16-TSSOP package | Higher code density requirement; same footprint upgrade path | Select when firmware size exceeds 4 KB or future scalability is needed without PCB change |
| S9S08SG16E2MTJ | 16 KB flash, 1 KB RAM, same HCS08 core and peripheral complement in 16-TSSOP | Complex control algorithms or protocol stacks requiring larger memory | Choose for designs anticipating feature expansion or multi-protocol support (e.g., LIN + I²C + SPI simultaneously) |
Compared with MC9S08SG8CTJ and S9S08SG16E2MTJ, the S9S08SG4E2MSC provides optimal balance of cost, power efficiency, and peripheral functionality for resource-constrained embedded control - especially where <4 KB flash and sub-1 µA stop3 current are design-critical.

FAQ
What is the maximum operating temperature specification for the S9S08SG4E2MSC?
The S9S08SG4E2MSC is rated for operation from –40°C to +125°C. This extended temperature range is validated per Freescale's MC9S08SG8/SG4 data sheet Rev. 8 (January 2014), and applies specifically to the 16-TSSOP package variant. High-temperature devices up to 150°C are available only in selected SG8 variants, not the S9S08SG4E2MSC.
Does the S9S08SG4E2MSC support LIN bus communication natively?
Yes, the S9S08SG4E2MSC supports LIN 2.x communication through its SCI module, which includes dedicated hardware features: LIN master extended break generation and LIN slave extended break detection. These capabilities are documented in Chapter 14 of the MC9S08SG8/SG4 data sheet and require no external transceiver for basic node implementation - though a LIN physical layer transceiver is still required for bus compliance.
How much flash memory does the S9S08SG4E2MSC contain, and is it reprogrammable in-system?
The S9S08SG4E2MSC contains 4 KB of on-chip flash memory that supports in-system programming (ISP) and in-application programming (IAP) over the full operating voltage (2.7–5.5 V) and temperature range (–40°C to +125°C). Flash erase and program operations are controlled via the FCMD register and supported by the FSTAT status register, enabling field firmware updates without removing the S9S08SG4E2MSC from the target board.
Can the S9S08SG4E2MSC operate in ultra-low-power mode while maintaining real-time wake-up capability?
Yes, the S9S08SG4E2MSC supports Stop3 mode - its deepest low-power state - where the CPU, flash, and most peripherals are disabled, yet the real-time counter (RTC), analog comparators (ACMP), and ADC remain operational using the on-chip 1 kHz low-power oscillator. This allows deterministic wake-up intervals or event-triggered resume without external components, achieving sub-microamp quiescent current.
What debug interface does the S9S08SG4E2MSC use, and what hardware is required?
The S9S08SG4E2MSC uses a single-wire background debug mode (BDM) interface accessible via the BKGD/MS pin. Debugging requires an NXP-compatible BDM pod (e.g., DEMO9S08SG8 evaluation board or standalone P&E Micro Cyclone PRO), which connects to a host PC via USB or RS-232. No JTAG header or additional pins are needed - the interface shares the BKGD/MS signal with boot-mode selection functionality.
