Introduction
The AcSiP AI1121L is a multi-band LoRa® connectivity module designed for Internet of Things (IoT) LoRaWAN applications.
It supports Sub-GHz (433-510MHz / 863–930MHz), 2.4GHz ISM, and 2.1GHz
satellite S-band communications.
The module features a compact size and an ultra-low power design, integrating a TCXO (temperature-compensated crystal oscillator) and an RF switch, is suitable for global use in smart homes, agricultural sensors, building automation, smart cities, asset tracking, retail store sensors, smart metering, and environmental monitoring.
Key Features
| ♦ Sub-GHz: 433~510MHz / 863~930MHz, receive sensitivity down to –141dBm (SF12 / 125kHz, RxBoosted = 1), transmit power up to +22dBm | |||
| ♦ 2.4GHz ISM: 2400-2500MHz global operation, sensitivity down to -114dBm (SF7 / 406kHz, RxBoosted = 1), transmit power up to +12dBm | |||
|
|||
| ♦ Modulation: LoRa, (G)FSK, and LR-FHSS (transmit-only) for enhanced anti-interference | |||

Receives an external low-frequency clock reference signal (32kHz) via the DIO11 pin.
This feature allows designers to inject a precise external clock signal into the device, enabling accurate timing in various scenarios, such as Wake On Radio applications that require synchronization protocols.
