S9S08QD2J1CSCR

Microcontrollers Overview

The S9S08QD2J1CSCR is an automotive-grade microcontroller from the NXP S08QD series, built on the 8-bit HCS08 CPU architecture. It features a maximum bus speed of 8 MHz at 5 V and operates within a voltage range of 2.7 V to 5.5 V. The device includes 2048 bytes of Flash memory and 128 bytes of RAM. Key peripherals consist of a 4-channel 10-bit ADC with hardware trigger capability, two timer/pulse-width modulators (TIM1 and TIM2), and a keyboard interrupt module. It utilizes an internal clock source module with FLL for precise frequency control.

Microcontrollers Feature Summary

• Integrated system protection mechanisms including low-voltage detection, illegal opcode/address detection, and flash block protection.
• Supports multiple power-saving modes such as Wait, Stop2, and Stop3 to optimize energy consumption in battery-operated applications.
• Features a 10-bit analog-to-digital converter with automatic compare functions and hardware trigger capabilities via the RTI counter.

Microcontrollers Applications

• Automotive body electronics and lighting control systems
• Sensor nodes requiring temperature monitoring and signal acquisition
• Simple logic controllers in cost-sensitive automotive modules

Microcontrollers Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm the presence of the 'J' suffix indicates the specified operating temperature range and the 'CSCR' suffix denotes the tape and reel packaging format. Ensure compatibility with existing PCB footprints and validate against the latest datasheet revision for any pinout or electrical characteristic updates.

Microcontrollers Selection Notes

Select this component when automotive qualification is mandatory for the application. Choose between MC9S08QD2 and S9S08QD2 variants based strictly on the required industrial versus automotive certification standards. Consider the limited I/O count and memory size when evaluating complex peripheral requirements or larger codebases.

Microcontrollers Part Context

This part belongs to the S08QD family, which provides a balance of performance and cost for embedded control tasks. The S9 prefix specifically designates the automotive-qualified version of the QD2 series, distinguishing it from the consumer/industrial MC9S08QD2 variant. It shares the same core architecture and peripheral set as its non-automotive counterparts.
