Z8FMC08100QKSG

Microcontrollers Overview

The Z8FMC08100QKSG is an 8-bit microcontroller from the Z8 Encore! MC family, based on the eZ8 CPU core. It features 8 KB of Flash program memory and 512 bytes of SRAM. The device operates at a maximum clock frequency of 20 MHz within a voltage range of 2.7 V to 3.6 V. It includes 17 general-purpose I/O pins, an 8-channel 10-bit ADC, and a 12-bit PWM module for motor control. Communication interfaces include I2C, SPI, and a full-duplex UART supporting LIN protocol. The component is housed in a QFN-32 package with an operating temperature range of 0°C to +70°C.

Microcontrollers Feature Summary

• Integrated 12-bit PWM module with complementary pairs and fault protection trip input for safe motor operation.
• Includes one operational amplifier for current sampling and one comparator for over-current limiting or shutdown.
• Features a high-speed 8-channel 10-bit ADC with sample and hold circuitry for voltage and back-EMF sensing.
• Supports single-pin debugging and in-circuit serial programming via a dedicated interface.

Microcontrollers Applications

• Control of single and multiphase variable-speed motors
• Large and small appliance motor management
• HVAC system control units
• Automotive electronic modules
• Power tool controller circuits

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'QKSG' confirms the QFN-32 package and standard commercial temperature range (0°C to +70°C). Ensure compatibility with existing PCB footprints for this package type. Confirm that the lead-free packaging designation meets environmental compliance requirements for the target assembly process. Cross-reference the manufacturer's latest datasheet for any updates to pinout or electrical characteristics before finalizing procurement.

Microcontrollers Selection Notes

Select this part when 8 KB of Flash memory is sufficient for application code and 17 GPIOs are required. Choose this model over variants with higher Flash capacity if cost or package size constraints exist. Verify that the 20 MHz processing speed meets real-time control loop requirements. Ensure the 2.7 V to 3.6 V supply voltage aligns with the system power architecture. Confirm that the standard temperature range is adequate for the intended operating environment.

Microcontrollers Part Context

This component belongs to the Z8FMC16100 Series, which also includes variants with 16 KB and 4 KB Flash memory. All series members share the same peripheral set, including the 12-bit PWM module, ADC, and communication interfaces. The primary differentiation between series members is the program memory size, while SRAM, GPIO count, and core specifications remain consistent across the family.

Microcontrollers Replacement Considerations

Direct substitutes within the same series include Z8FMC16100QKSG (16 KB Flash) and Z8FMC04100QKSG (4 KB Flash), provided memory requirements allow. For extended temperature ranges, consider Z8FMC08100QKEG. Package variations such as LQFP-32 options like Z8FMC08100AKSG require schematic and layout modifications due to different pinouts.
