NRF51422-CEAA-R

RF Transceiver ICS Overview

The nRF51422 is a Bluetooth Low Energy and ANT single-chip system-on-chip (SoC) from Nordic Semiconductor, designed for ultra-low power wireless applications. It integrates a 32-bit ARM Cortex-M0 processor with 256 kB of flash memory and 32 kB of RAM. The device features a flexible 2.4 GHz radio supporting BLE and ANT/ANT+ protocols. It operates within a voltage range of 1.8 V to 3.6 V and includes 31 general-purpose input/output pins. The component is housed in a 48-pin QFN package.

RF Transceiver ICS Feature Summary

• Integrates a 32-bit ARM Cortex-M0 core with substantial non-volatile storage and data memory for complex firmware execution.
• Supports dual-mode wireless connectivity via the integrated 2.4 GHz radio for both Bluetooth Low Energy and ANT/ANT+ networks.
• Features Programmable Peripheral Interconnect (PPI) allowing peripherals to interact directly without CPU intervention to reduce power consumption.

RF Transceiver ICS Applications

• Development and evaluation of ANT/ANT+ wireless network protocols
• Design of ultra-low power Bluetooth Low Energy devices
• Implementation of proprietary 2.4 GHz wireless solutions

RF Transceiver ICS Procurement Notes

Verify the specific suffix CEAA against official Nordic Semiconductor documentation to confirm exact packaging, tape-and-reel specifications, and regional compliance status. Confirm current availability status as nRF51 series components may be subject to end-of-life notices or limited supply conditions. Ensure compatibility with existing design-in tools and SDK versions before procurement.

RF Transceiver ICS Selection Notes

Select this SoC when a single chip must support both BLE and ANT/ANT+ protocols simultaneously. It is suitable for applications requiring low active current and deep sleep modes. Consider the 256 kB flash size for firmware requirements. Evaluate the 48-pin QFN package constraints for PCB layout. Compare against nRF51822 if ANT protocol support is not required.

RF Transceiver ICS Part Context

The nRF51422 belongs to the nRF51x22 family of Bluetooth SoCs. It shares the same hardware architecture as the nRF51822 but differs in software stack support, specifically targeting ANT/ANT+ alongside BLE. This differentiation allows designers to optimize for specific wireless standards while utilizing the same underlying silicon platform and development ecosystem.

RF Transceiver ICS Replacement Considerations

The nRF51822 is a compatible alternative if ANT protocol support is not required. Verify pin-to-pin compatibility and ensure that the replacement part number matches the required package type and suffix specifications.
