Overview

The CY8C4248LQI-BL593 is a PSoC 4 BLE system-on-chip that combines a 48MHz Arm Cortex-M0 core with a Bluetooth 4.2 radio and programmable analog/digital blocks. It features 256KB of Flash and 32KB of RAM, specifically designed for low-power wireless applications requiring custom hardware peripherals and capacitive touch sensing.

Why Choose This Part

This SoC distinguishes itself with CapSense technology for robust touch interfaces and Universal Digital Blocks (UDBs) that allow for custom digital logic. Its wide supply voltage range of 1.71V to 5.5V and extremely low power consumption (down to 60nA in stop mode) make it highly efficient for diverse power environments.

Applications

Bluetooth Smart Sensors
Ideal for battery-operated wireless sensor nodes utilizing the integrated BLE 4.2 stack and low-power modes.
Wearable Devices
Suited for fitness trackers and smartwatches where the 7x7mm QFN package and CapSense touch UI are critical.
Wireless Human Interface Devices
Used in wireless mice, keyboards, and remote controls that require long battery life and custom gesture control.
Medical Monitoring
The programmable analog front-end allows for direct interfacing with various medical transducers in a compact form factor.
