Product details
Overview
S9S08QD2J1MSC from NXP Semiconductors is an 8-bit HCS08 microcontroller with a 16 MHz CPU, 2048 bytes of on-chip Flash memory, and 128 bytes of RAM, designed for cost-sensitive embedded control in automotive and industrial applications. It integrates ADC, dual timer/PWM modules (TIM1 and TIM2), keyboard interrupt, and background debug support.
For engineers reviewing the S9S08QD2J1MSC datasheet, S9S08QD2J1MSC pinout, S9S08QD2J1MSC application, or S9S08QD2J1MSC equivalent, key selection criteria include Flash/RAM size, 8-pin SOIC packaging, internal clock source (ICS) with FLL, COP watchdog, and LVD reset functionality under extended temperature operation.
Technical Context
The S9S08QD2J1MSC implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting single-wire background debugging and up to 32 interrupt/reset sources. Its ICS module delivers precise clock generation via frequency-locked-loop (FLL) with internal reference trimming (0.2% resolution, ±2% deviation over voltage/temperature).
Peripherals include a 4-channel 10-bit ADC with hardware trigger (RTI), two independent timer/PWM modules (TIM1: 2-channel; TIM2: 1-channel), and a 4-pin keyboard interrupt (KBI) with software-selectable edge/level sensitivity. All operate within –40 °C to +125 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | HCS08 8-bit CPU running at 16 MHz - enables deterministic real-time control with low latency interrupt response. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08QD2CPBE | Same core, Flash/RAM, and peripherals; differs in package (8-pin PDIP) and temperature grade (–40 °C to +85 °C). | Targeted at non-automotive prototyping and lab evaluation where SOIC reflow is unavailable. | Select when through-hole assembly or lower-temperature operation suffices and debug interface compatibility is retained. |
| S9S08QD4J1MSC | Same package and temperature range, but doubles Flash (4096 B) and RAM (256 B); identical peripheral set. | Suitable for applications requiring larger firmware (e.g., bootloader + application, enhanced diagnostics). | Choose when future firmware expansion or field-upgrade capability is required without changing PCB layout. |
Compared with MC9S08QD2CPBE, the S9S08QD2J1MSC offers higher temperature resilience and surface-mount compatibility; compared with S9S08QD4J1MSC, it trades memory capacity for cost and footprint efficiency in resource-constrained designs.

FAQ
What is the maximum operating frequency of the S9S08QD2J1MSC?
The S9S08QD2J1MSC features an HCS08 CPU core rated for up to 16 MHz operation. This frequency is achieved using the internal clock source (ICS) with its frequency-locked-loop (FLL) and precision-trimmed reference oscillator. The actual bus clock depends on ICS configuration but supports full-speed execution across the specified voltage (2.7–5.5 V) and temperature (–40 °C to +125 °C) ranges. The S9S08QD2J1MSC does not require an external crystal to reach this speed.
Does the S9S08QD2J1MSC support in-circuit debugging?
Yes, the S9S08QD2J1MSC includes a single-wire background debug interface (BDM) accessible via the BKGD/MS pin. It supports breakpoint setting (one active breakpoint plus two more in the on-chip debug module), real-time register inspection, and flash programming without requiring additional debug headers or JTAG circuitry. This capability is fully functional in-circuit and is documented in the MC9S08QD4 Series Data Sheet Rev. 7.
What are the Flash and RAM sizes of the S9S08QD2J1MSC?
The S9S08QD2J1MSC contains 2048 bytes of on-chip Flash memory and 128 bytes of RAM. These values are explicitly defined in the "Memory" section of the MC9S08QD4 Series Data Sheet (Rev. 7, August 2022), which covers both MC9S08QD2 and S9S08QD2 variants. Flash supports read/program/erase over full operating voltage and temperature, and RAM is volatile SRAM used for stack and data storage during runtime.
Is the S9S08QD2J1MSC qualified for automotive applications?
Yes, the S9S08QD2J1MSC is automotive-qualified with an operating temperature range of –40 °C to +125 °C and compliance with AEC-Q100 stress test requirements. The "J" in the part number denotes the automotive temperature grade, and the "MSC" suffix indicates the 8-pin SOIC package. Documentation confirms its inclusion in the S9S08QD2 family covered by the MC9S08QD4 Series Data Sheet, which explicitly lists S9S08QD2 for automotive applications starting in Revision 3 (November 2007).
What peripherals are integrated into the S9S08QD2J1MSC?
The S9S08QD2J1MSC integrates a 4-channel 10-bit ADC with automatic compare and temperature sensor, two timer/PWM modules (TIM1 with 2 channels and TIM2 with 1 channel), a 4-pin keyboard interrupt (KBI) module with configurable polarity, and system-level features including COP watchdog, low-voltage detect (LVD), illegal opcode/address detection, and flash block protection. All peripherals are accessible via the 8-pin SOIC I/O mapping described in the device pin assignment chapter.
