SimpleLink CC2652RSIP is a SiP-certified module, multiprotocol 2.4 GHz wireless microcontroller (MCU) from Texas Instruments.

It available at distributor Digi-Key.

It supports Thread, Zigbee, Bluetooth 5.2 Low Energy, IEEE 802.15.4, IPv6-enabled smart objects (6LoWPAN), and proprietary systems including the TI 15.4-Stack (2.4 GHz) and concurrent multiprotocol through a dynamic multiprotocol manager (DMM) driver.

The device is optimised for low-power wireless communication and advanced sensing in building security systems, HVAC, medical, wired networking, portable electronics, home theatre and entertainment, and connected peripherals markets.

The CC2652RSIP features a small 7 mm x 7 mm certified SiP module 2.4 GHz with integrated DC/DC components, balun, and crystal oscillators.

It offers wide flexibility of protocol stack support in the SimpleLink CC13xx and CC26xx software development kit (SDK). Wireless applications with a longer battery life can operate at a low standby current of 1 µA with full RAM retention.

The device is industrial temperature ready with an ultra-low standby current of 11 µA at +105°C. The programmable, autonomous ultra-low-power sensor controller CPU with fast wakeup capability enables advanced sensing.

As an example, the sensor controller is capable of 1 Hz ADC sampling at 1 µA system current. The low soft-error rate (SER) failure-in-time (FIT) provides for a long operation lifetime with no disruption in industrial markets with always-on SRAM parity against corruption due to potential radiation events.

The dedicated software-controlled radio controller (Arm® Cortex®-M0) provides flexible low-power RF transceiver capability to support multiple physical layers and RF standards. The module offers excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth LE (-103 dBm for 125 kbps LE-coded PHY).

The CC2652RSIP is part of the SimpleLink MCU platform which consists of Wi-Fi, Bluetooth LE, Thread, Zigbee, Sub-1 GHz MCUs, and host MCUs that share a common, easy-to-use development environment with a single core software development kit (SDK) and a rich toolset.

A one-time integration of the SimpleLink platform allows for any combination of the portfolio devices to be added into the design allowing for 100% code reuse when design requirements change.

Applications are ISM and SRD systems, building automation, asset tracking in industrial transportation, medical, communications equipment, and personal electronics.
