Overview

The CY8C4247AXI-M485 is an ARM Cortex-M0 microcontroller from the PSoC 4200M series. It features a maximum operating frequency of 48 MHz, 128 kByte Flash memory, and 32 kByte SRAM. The device includes one SAR ADC with 12-bit resolution at 1 MSPS, two comparators, four SCB modules, eight TCPWM blocks, and eight DMA channels. It provides 54 GPIO pins and supports CAPSENSE technology. The unit operates within a voltage range of 1.71 V to 5.5 V and a temperature range of -40 °C to 85 °C.

Feature Summary

• Integrates programmable analog and digital blocks for flexible system design
• Supports capacitive sensing applications via built-in CAPSENSE technology
• Includes multiple communication interfaces through Serial Communication Blocks
• Features low-power operation capabilities suitable for battery-powered devices

Applications

• Industrial control systems requiring CAN communication
• Smart home appliances with touch interface requirements
• Portable medical devices needing precise analog signal acquisition
• Automotive body electronics and sensor nodes

Procurement Notes

Verify the specific package type and marking code corresponding to the AXI suffix during procurement. Confirm that the M485 variant matches the required thermal and electrical specifications for the target environment. Ensure compatibility with existing firmware libraries designed for the PSoC 4200M architecture before finalizing orders.

Selection Notes

Select this component when a balance of processing speed and analog flexibility is required. The 48 MHz CPU core offers sufficient performance for complex logic while maintaining low power consumption. The inclusion of dedicated CAPSENSE hardware simplifies user interface implementation compared to general-purpose MCUs lacking such peripherals.

Part Context

This part belongs to the Infineon PSoC 4200M family, which combines an ARM Cortex-M0 processor with configurable analog and digital blocks. The family is designed for cost-sensitive applications requiring high integration. The CY8C4247 variant specifically targets designs needing moderate memory capacity and extensive I/O connectivity.

Replacement Considerations

Direct substitutes include other CY8C4247 variants with different packages or temperature grades, such as CY8C4247AZI-M485 or CY8C4247LTI-L485. Verify pin compatibility and peripheral configuration differences when considering cross-series replacements within the PSoC 4 portfolio.
