CYW20719B2KUMLG

RF Transceiver ICS Overview

The CYW20719B2KUMLG is a Bluetooth 5.1 System-on-Chip (SoC) from Infineon Technologies, integrating a 2.4 GHz transceiver with an ARM Cortex-M4 microcontroller core. It features 1 MB of Flash memory, 2 MB of ROM, and 512 kB of RAM. The device operates within a supply voltage range of 1.76 V to 3.63 V and supports a maximum clock frequency of 96 MHz. It includes ADC resolutions of 10-bit and 13-bit, interfaces such as I2C, SPI, UART, GPIO, HCI, I2S, PCM, and PWM. The component is housed in a 40-UFQFN package with exposed pads, rated for operation between -30°C and +85°C.

RF Transceiver ICS Feature Summary

• Integrates a Bluetooth 5.1 radio with an ARM Cortex-M4 processor for low-power dual-mode connectivity.
• Provides substantial onboard storage with 1 MB Flash and 2 MB ROM alongside 512 kB RAM.
• Supports multiple serial communication protocols including I2C, SPI, UART, and high-speed audio interfaces.

RF Transceiver ICS Applications

• Single-chip AIROC Bluetooth application development
• Bluetooth Low Energy (BLE) peripheral devices
• Audio streaming applications utilizing I2S and PCM interfaces

RF Transceiver ICS Procurement Notes

Verify the current lifecycle status before integration, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the 40-UFQFN package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS3 specifications and check Moisture Sensitivity Level (MSL) handling procedures during assembly. Validate that the available GPIO count meets your interface needs.

RF Transceiver ICS Selection Notes

Select this SoC when a combined Bluetooth 5.1 radio and MCU are required in a compact form factor. It is suitable for designs needing significant program memory (1 MB Flash) and data storage (2 MB ROM). Consider the 40-pin QFN package constraints and the specific voltage range of 1.76 V to 3.63 V for power management architecture.

RF Transceiver ICS Part Context

This part belongs to the Infineon CYW20719 series of wireless microcontrollers. It is distinct from variants like the CYW20719B1KUMLG or CYW20719B2KUMLGT by its specific pinout, memory configuration, and lack of integrated GNSS capabilities found in some other SKUs. It serves as a standalone processor for Bluetooth applications.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Check for availability of CYW20719B1KUMLG or CYW20719B2KUMLGT, noting differences in package type, memory size, and feature sets such as GNSS support.
