nRF51822-QFAA-R

nRF51822 Multiprotocol Bluetooth low energy and 2.4GHz proprietary System-on-Chip ULP wireless System-on-Chip The nRF51822 is a powerful multiprotocol single chip solution for ULP wireless applications. It incorporates Nordic’s latest best-in-class performance radio transceiver, an ARM® Cortex™ M0 CPU and 256kB/128kB flash and 32kB/16kB RAM memory. The nRF51822 supports Bluetooth® low energy (formerly known as Bluetooth Smart) and 2.4 GHz protocol stacks. 32kB/16kB RAM GPIO APB bus 256kB/ 128kB Flash AHB Lite bus Timers / Counters Analog I/O Digital I/O System Peripherals Processor 16 MHz 32-bit ARM Cortex-M0 CPU Radio Power supply Oscillators Multiprotocol 2.4GHz Lower power and higher performance The nRF51822 uses the 32-bit ARM Cortex M0 MCU, together with extensive flash availability, 256kB/128kB in total with 40kB-180kB available for application development. Code density and execution speed are considerably greater than for 8/16-bit platforms. The Programmable Peripheral Interconnect (PPI) system provides a 16-channel bus for direct and autonomous system peripheral communication without CPU intervention. This brings predictable latency times for peripheral to peripheral interaction and power saving benefits associated with leaving the CPU idle. The device has 2 global power modes ON/OFF, but all system blocks and peripherals have individual power management control which allows for an automatic switching RUN/IDLE for system blocks based only on those required/not required to achieve particular tasks. The new radio forms the basis of the nRF51822’s performance. The radio supports Bluetooth low energy and is on air compatible with the nRF24L Series products from Nordic Semiconductor. Output power is now scalable from a maximum of +4dBm down to -20dBm in 4dB steps. Sensitivity is increased at every level and offers sensitivity ranges (dependent on data rate) from -96 to -85dBm, with -93dBm for Bluetooth low energy.

This means compile, link and run-time dependencies with the embedded stack and associated de-bugging challenges are removed. The Bluetooth low energy stack is a pre-compiled binary available from Nordic Semiconductor, leaving application code to be compiled stand-alone. The embedded stack interface uses an asynchronous and event-driven model removing the need for RTOS frameworks. OTA DFU The nRF51822 is supported by a Over The Air Device Firmware Upgrade (OTA-DFU) feature. This allows for in the field updates of application software and SoftDevices. Maximum re-use and easy migration The devices in the nRF51 Series are pin compatible enabling migration between technologies such as Bluetooth low energy and ANT with no layout changes. The common HW architecture ensures that one codebase can be re-used effortlessly between nRF51 Series devices. Variants in the nRF51 Series enable simple choices tailoring device selection to desired wireless protocol and feature requirements with little or no changes. Application code Bluetooth low energy Protocol Stack Gazell Protocol Stack SoC SoftDevices The Nordic protocol stacks are known as SoftDevices and complement the nRF51 Series SoCs. All nRF51 Series are programmable with software stacks available from Nordic Semiconductor. This brings maximum flexibility to application development and allows the latest stack version to be programmed into the nRF51 Series SoC.
