CYW20702B0KWFBGT

CYW20702B0KWFBGT is a Cypress (now Infineon) Bluetooth Low Energy System‑on‑Chip (SoC) from the CYW20702 family. It integrates a 2.4 GHz BLE radio with a microcontroller, enabling compact wireless devices such as wearables and sensors. The device provides an MCU core, embedded flash and RAM, and multiple peripherals (SPI/I2C/UART, GPIOs, timers, and analog blocks) with several low‑power modes for battery‑powered operation. It supports Bluetooth LE central/peripheral roles, advertising, scanning, pairing, and basic security features, and runs firmware written for Cypress’ WICED Studio/ModusToolbox SDKs. The suffix KWFBGT identifies the exact package, temperature grade, and variant. Because it’s a system‑on‑chip, you don’t need an external radio; however you’ll need the appropriate SDK, toolchain, and programming/debug interfaces to develop and flash firmware. Typical uses include fitness trackers, smartwatches, wireless accessories, and other compact BLE devices. For exact specs, check the datasheet and product brief.
