Product details
Overview
STEVAL-IKR001V8D from STMicroelectronics is an 868 MHz RF daughterboard based on the SPIRIT1 sub-GHz transceiver, integrated with a SkyWorks® power amplifier to deliver +27 dBm output power, -123 dBm receiver sensitivity, and support for 2-FSK/GFSK/MSK/GMSK/OOK/ASK modulation at data rates from 1 to 500 kbps - deployed in wireless M-BUS metering systems.
For engineers reviewing the STEVAL-IKR001V8D datasheet, STEVAL-IKR001V8D pinout, STEVAL-IKR001V8D application, or STEVAL-IKR001V8D equivalent, key selection considerations include its TCXO-stabilized narrowband operation, AES-128 encryption co-processor, SPI interface compatibility with STM32L MCUs, and SAW-filtered RX path for out-of-band interference rejection in dense ISM band deployments.
Technical Context
The board implements a complete RF range extender architecture: SPIRIT1 handles baseband modulation/demodulation and protocol engine (ACK/retransmission/timeout), while the external SkyWorks® power amplifier enables high-output (+27 dBm) transmission without compromising low-power RX/TX duty cycle operation.
It uses a TCXO for frequency stability required by narrowband wireless M-BUS Class C/C1 compliance, and integrates a SAW filter in the receive path to suppress adjacent-channel interference - critical for reliable operation in unlicensed 868 MHz industrial environments with multiple concurrent transmitters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Band | 868 MHz ISM band - optimized for European wireless M-BUS infrastructure and smart utility metering. |
| Max Output Power | +27 dBm (500 mW) - enables extended range up to several kilometers in line-of-sight outdoor deployments. |
| Receiver Sensitivity | -123 dBm @ 1.2 kbps - supports robust link budget in low-SNR urban or underground metering nodes. |
| Data Rate Range | 1–500 kbps - covers both ultra-low-power long-range (e.g., 1.2 kbps M-BUS) and higher-throughput sensor telemetry modes. |
| Modulation Support | 2-FSK, GFSK, MSK, GMSK, OOK, ASK - ensures interoperability with legacy and next-gen sub-GHz protocols. |
| Encryption | AES-128 co-processor - hardware-accelerated payload encryption for secure firmware updates and meter reading data. |
| Interface | SPI - direct connection to STM32L-series microcontrollers with minimal GPIO overhead and deterministic timing control. |

FAQ
Is STEVAL-IKR001V8D a standalone transceiver IC or a development board?
STEVAL-IKR001V8D is a daughterboard evaluation kit - not an IC. It integrates the SPIRIT1 transceiver IC, SkyWorks® power amplifier, TCXO, SAW filter, matching network, and antenna interface. It requires a host carrier board (e.g., STM32L Discovery) for MCU control and power management.
Does it support wireless M-BUS Mode N or T?
Yes - the SPIRIT1 transceiver on this board natively supports all wireless M-BUS physical layer modes (N, T, S, C) per EN 13757-4, with configurable symbol rate, modulation, and preamble length. Firmware examples for Mode C (100 kHz channel spacing, 1.2 kbps) are provided in the associated SDK.
What is the role of the SAW filter on this board?
The SAW filter is placed in the receive signal path before the SPIRIT1's LNA input. It provides >40 dB rejection of out-of-band signals beyond ±5 MHz from 868 MHz, preventing desensitization in environments with strong nearby transmitters (e.g., GSM900 base stations or other ISM devices).
Can STEVAL-IKR001V8D operate at 915 MHz?
No - it is tuned exclusively for the 868 MHz band (863–870 MHz). The matching network, SAW filter, and PA output stage are fixed for that band. For 915 MHz, ST recommends STEVAL-IKR002V2 (based on same SPIRIT1 but tuned for 902–928 MHz).
