MC9S08QG8CFKE

Microcontrollers Overview

The MC9S08QG8CFKE is an 8-bit microcontroller from the S08 family, manufactured by NXP USA Inc. It features a 20 MHz HCS08 CPU core with 8 Kbytes of FLASH memory and 512 bytes of RAM. The device operates within a voltage range of 1.8V to 3.6V and supports an operating temperature range of -40°C to 85°C. It includes an 8-channel, 10-bit analog-to-digital converter (ADC), serial communication interfaces including SCI, SPI, and IIC, and multiple timer modules. The component is housed in a 24-pin Quad Flat No-lead (QFN) package.

Microcontrollers Feature Summary

• Integrated 20-MHz HCS08 CPU core with background debugging capabilities
• On-chip FLASH memory allowing read/program/erase operations over full operating conditions
• Comprehensive peripheral set including 10-bit ADC, analog comparator, and multiple serial interfaces
• Low-power operation with Wait mode and three Stop modes

Microcontrollers Applications

• Distributed monitoring systems for accumulator voltage and temperature
• Battery management units in backup power supply equipment
• General-purpose embedded control applications requiring low-voltage operation

Microcontrollers Procurement Notes

Verify the specific suffix CFKE corresponds to the 24-QFN package variant when sourcing. Confirm that the component status is discontinued as indicated in distributor records. Ensure compatibility with existing PCB footprints for the 24-QFN-EP package. Check for any product change notices regarding wire bond material migration affecting mechanical dimensions.

Microcontrollers Selection Notes

Select this part for designs requiring an 8-bit MCU with integrated FLASH and low-voltage support. Consider the 24-QFN package for space-constrained surface-mount applications. Evaluate the available I/O pins against system interface requirements. Verify that the internal clock source precision meets timing constraints without external oscillators.

Microcontrollers Part Context

This component belongs to the MC9S08QG series of 8-bit microcontrollers. It shares architectural similarities with other members like the MC9S08QG8CPBE but differs in packaging. The series is designed for cost-effective general-purpose applications. It utilizes SuperFlash technology for non-volatile memory operations.
