IFXCY8C4248LQI-BL553

Overview

The CY8C4248LQI-BL553 is an integrated PSoC 4 BLE solution combining a 48 MHz Arm Cortex-M0 core with a Bluetooth Low Energy radio and programmable analog and digital blocks. It features 256 KB of Flash and 32 KB of RAM, operating over a wide voltage range of 1.71V to 5.5V. This SoC is designed for projects requiring both wireless connectivity and custom hardware peripherals in a compact 36-pin QFN package.

Why Choose This Part

The PSoC architecture allows for highly flexible hardware configuration, including 8 channels of DMA and programmable analog blocks that reduce PCB complexity. It supports a wide 5.5V operating limit and 5V tolerant I/O, providing robust electrical compatibility compared to many 3.3V-only wireless SoCs.

Applications

Getting Started

Developers should use the PSoC Creator IDE or ModusToolbox for schematic-based hardware configuration and firmware development. For hardware evaluation, the CY8CKIT-042-BLE-A Pioneer Kit is the standard platform for testing BLE applications and CapSense integration. Programming is typically handled via the onboard SWD interface using a MiniProg3 or KitProg debugger.
