IFXCY8C4128LQI-BL543
Overview
The CY8C4128LQI-BL543 is a PSoC 4 BLE system-on-chip that combines an Arm Cortex-M0 core with integrated Bluetooth Low Energy (BLE) connectivity. It features programmable analog and digital blocks, including Infineon's CapSense technology for advanced touch-sensing interfaces. Operating at up to 24 MHz with 256 KB of Flash and 32 KB of RAM, it is designed for wireless connectivity in power-constrained environments.
Why Choose This Part
This SoC integrates a complete BLE radio stack and a flexible analog front-end, reducing BOM count for wireless designs. It supports a wide operating voltage range from 1.71V to 5.5V and features 5V-tolerant I/O, providing robust compatibility with various power rails and peripheral logic levels.
Applications
Getting Started
Designers should use the PSoC Creator IDE or ModusToolbox for firmware development and hardware configuration of the programmable blocks. The CY8CKIT-042-BLE-A Pioneer Kit is the recommended hardware platform for prototyping and debugging BLE applications. For custom board layouts, ensure proper impedance matching for the integrated RF balun and antenna trace.
Also Consider
STMicroelectronics
- Features a dual-core architecture (Cortex-M4 and Cortex-M0+) for better separation of application logic and the wireless stack.
