AMS001R

Overview

The AMS001R is a Bluetooth Low Energy (BLE) transceiver module manufactured by Silicon Labs, designed for surface-mount integration. It operates at the standard 2.4GHz ISM band and supports the Bluetooth v4.1 protocol with a maximum data rate of 1Mbps. The module features an integrated antenna and DC-DC converter, delivering a transmit power of 4dBm. It includes 1MB of serial flash memory and accepts a supply voltage range of 1.8V to 3.6V. Key electrical specifications include a receiver sensitivity of -94dBm, a receive current of 26.6mA, and a transmit current of 22mA. The device utilizes DSSS and GFSK modulation schemes and is housed in a compact SMD package suitable for space-constrained designs.

Procurement Notes

Verify component authenticity through authorized channels as availability may be limited. Confirm that the specific AMS001R variant matches the required firmware version and hardware revision for your design. Ensure compatibility with the host microcontroller's voltage levels and interface protocols before finalizing procurement decisions.

Selection Notes

Select this module when a compact BLE solution with integrated power management and antenna is required. Consider the 1MB flash capacity for local data logging needs. Evaluate the 2.4GHz frequency range against potential interference sources in the deployment environment to ensure reliable connectivity performance.

Part Context

The AMS001R belongs to the AMS series of wireless modules from Silicon Labs, which are engineered for low-power IoT applications. This series typically pairs with Silicon Labs' EFM8 or EFR32 microcontrollers to create complete wireless systems. The module simplifies RF design by handling complex analog front-end requirements within a single surface-mount package.
