Overview

The CY8C4248LQI-BL573 is a highly integrated PSoC 4 BLE SoC that combines a 48MHz Arm Cortex-M0 core with a Bluetooth 4.2 radio and programmable analog and digital blocks. It features 256KB of flash and 32KB of RAM, specifically designed for low-power wireless applications requiring custom hardware peripherals. The device stands out for its CapSense technology and Universal Digital Blocks (UDBs), which allow for hardware-level customization without increasing CPU overhead.

Why Choose This Part

This PSoC 4 variant offers exceptional flexibility through its 4 Universal Digital Blocks and programmable analog front-end, reducing the need for external discrete components. It provides a wide operating voltage range up to 5.5V and features industry-leading CapSense Sigma-Delta technology for robust touch sensing in noisy environments.

Applications

Wireless Human Interface Devices
Ideal for battery-powered mice, keyboards, and remote controls utilizing BLE connectivity and CapSense touch interfaces.
Smart Home Sensors

Getting Started

Developers should use PSoC Creator or ModusToolbox for hardware configuration and firmware development. The CY8CKIT-042-BLE-A Pioneer Kit is the recommended hardware platform for prototyping Bluetooth Low Energy applications with this silicon family. Practical development involves using the TopDesign schematic editor to drag-and-drop components like the BLE stack, SAR ADC, and UDB-based logic.
