Overview

The CY8C6245LQI-S3D42 is a high-performance, dual-core PSoC 62 microcontroller designed for power-efficient embedded applications. It features a 150MHz Arm Cortex-M4F for primary processing and a 100MHz Arm Cortex-M0+ for low-power system management, integrated with 512KB of Flash and 256KB of SRAM. This MCU includes Infineon's CapSense technology for advanced touch-sensing interfaces and a dedicated hardware cryptographic accelerator for secure IoT operations.

Why Choose This Part

The dual-core architecture allows for a granular power-performance trade-off, consuming as little as 4.8mA during simultaneous 100MHz operation. It offers extensive security features like an OTP eFuse and XIP-capable QSPI with encryption, alongside specialized analog blocks including a 12-bit SAR ADC and segment LCD drive.

Applications

Wearable Devices
Utilizes the ultra-low power modes and dual-core architecture to manage sensor fusion on the CM4 while handling background tasks and connectivity on the CM0+.
Smart Home Interfaces
Leverages integrated CapSense for reliable touch buttons, sliders, and proximity sensing in thermostats and lighting controllers.
Industrial IoT Sensors
Employs the hardware cryptographic engine (AES, RSA, SHA) to secure data transmission and the 12-bit SAR ADC for precise industrial measurements.
Portable Medical Monitoring
Combines high-performance processing for waveform analysis with low-current hibernation modes to extend battery life in mobile diagnostic equipment.
