NRF9160-SIBA-B1A-R

RF Transceiver ICS Overview

The NRF9160-SIBA-B1A-R is a System-in-Package (SiP) from Nordic Semiconductor designed for low-power cellular IoT applications. It integrates an LTE-M/NB-IoT modem, Arm Cortex-M33 processor with 1 MB Flash and 256 KB RAM, GNSS receiver, RF front-end, and power management. This specific variant supports NB-IoT only. It features global band support including B1, B2, B3, B4, B5, B8, B12, B13, B14, B17, B18, B19, B20, B25, B26, B28, and B66. The device includes security features like Arm TrustZone and CryptoCell, supporting eDRX and PSM for energy efficiency.

RF Transceiver ICS Feature Summary

• Integrates LTE-M/NB-IoT modem with GNSS receiver and Arm Cortex-M33 application processor in a compact SiP
• Provides advanced security through Arm TrustZone isolation and Arm CryptoCell cryptographic acceleration
• Supports global connectivity with certified LTE bands and energy-saving modes like eDRX and PSM
• Includes comprehensive peripheral interfaces such as SPI, I²C, UART, ADC, and PWM for sensor integration

RF Transceiver ICS Applications

• Wildlife tracking devices requiring lightweight, long-battery-life monitoring
• Smart metering and utility infrastructure monitoring
• Asset tracking and logistics solutions
• Environmental sensing and remote data collection

RF Transceiver ICS Procurement Notes

Verify the specific ordering suffix to confirm regional certification status and supported frequency bands. Ensure compatibility with existing antenna designs and regulatory requirements for target markets. Confirm supply availability through authorized Nordic Semiconductor distributors or direct channels. Check for latest firmware versions to ensure optimal performance and security patches are accessible via FOTA capabilities.

RF Transceiver ICS Selection Notes

Select this component when NB-IoT connectivity is sufficient and lower cost or simpler configuration is preferred over multi-mode LTE-M. Consider the integrated GNSS if location tracking is required without external modules. Evaluate the need for Arm TrustZone and CryptoCell for secure data transmission. Compare against nRF9161 if DECT NR+ or LTE-M support is also necessary for the application.

RF Transceiver ICS Part Context

The nRF9160 series represents Nordic Semiconductor's highly integrated cellular IoT solution. The NRF9160-SIBA-B1A-R is a specific variant within this family, distinguished by its NB-IoT-only capability compared to other variants that may support LTE-M as well. It shares the same core architecture, including the Cortex-M33 processor and security features, ensuring consistent development experience across the nRF9160 product line.

RF Transceiver ICS Replacement Considerations

nRF9160-SICA-B1A-R: Supports both LTE-M and NB-IoT, offering broader network compatibility but potentially higher complexity or cost. nRF9161: Adds DECT NR+ support alongside LTE-M/NB-IoT, suitable for mesh networking applications. Developers should verify if the additional LTE-M or DECT NR+ capabilities are needed before switching.
