Overview
The CY8C4247BZI-L479 is a PSoC™ 4200L microcontroller based on the Arm® Cortex®-M0 CPU, operating at up to 48 MHz. It features 128 kB of Flash memory and 16 kB of SRAM. The device includes one 12-bit SAR ADC with a maximum sampling rate of 1 MSPS. It provides 98 programmable GPIOs within a 124-ball VFBGA package. Power supply ranges from 1.71 V to 5.5 V, with an operating temperature range of -40 °C to 85 °C.
Feature Summary
- Integrates programmable analog blocks including opamps and comparators that operate in Deep Sleep mode for low-power applications.
- Supports capacitive sensing via two Infineon Capacitive Sigma-Delta (CSD) blocks with automatic hardware tuning capabilities.
- Includes flexible digital subsystems with Universal Digital Blocks (UDBs) allowing custom logic implementation.
- Features integrated USB Full-Speed client controller and multiple serial communication blocks.
Applications
- Battery-powered portable devices requiring low power consumption
- Industrial control systems utilizing CAN or serial communication
- Consumer electronics with capacitive touch interfaces
- Smart home appliances with LCD segment drive requirements
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with the required voltage levels and interface standards before integration. Cross-reference the component marking code with the official documentation to prevent counterfeit substitution.
Selection Notes
Select this model when a balance of moderate Flash capacity and extensive GPIO count is required. The 124-ball VFBGA package suits designs needing high pin density in a compact footprint. Consider the available DMA channels and programmable analog resources for complex signal processing tasks without external components.
Part Context
This component belongs to the PSoC™ 4200L family, designed for low-power embedded applications. It combines a standard ARM Cortex-M0 core with reconfigurable analog and digital blocks. The family emphasizes flexibility through programmable interconnects and supports migration from other Cypress/Infineon MCU families.
Replacement Considerations
Check the PSoC™ 4200L family selector guide for alternatives with different Flash sizes or package options. Verify if other suffixes offer the same VFBGA-124 package but with different temperature ratings or lead finishes.
