Overview

The CY8C4248LQI-BL543 is a member of the PSoC 4 BLE family, combining a 48MHz Arm Cortex-M0 core with a built-in Bluetooth Low Energy radio and programmable analog and digital blocks. It features 256KB of Flash and 32KB of RAM, operating across a wide voltage range of 1.71V to 5.5V. This SoC is specifically designed for applications requiring wireless connectivity, integrated CapSense touch sensing, and low power consumption.

Why Choose This Part

The PSoC 4 architecture offers unique flexibility by allowing engineers to configure programmable digital and analog blocks, reducing external component count. It features a highly efficient Deep Sleep mode consuming only 1.5 microamps, making it ideal for devices that spend most of their time in standby.

Applications

Wireless IoT Sensors
Utilizes the integrated BLE radio and 12-bit ADC to collect and transmit environmental data while maintaining low power consumption.
Wearable Devices
Leverages the small QFN footprint and integrated CapSense technology for sleek, touch-enabled user interfaces in battery-powered electronics.
Smart Home Controllers
Functions as a central bridge using its multiple serial interfaces (I2C, SPI, UART) and BLE to coordinate between sensors and mobile apps.
Industrial Remote Monitoring
Employs 5V tolerant I/O and a wide supply range to interface with industrial sensors and provide wireless diagnostics.
