Description
The DA14594 is a dual-core wireless microcontroller, combining the latest Arm® Cortex®-M33™ application processor with floating-point unit, Cortex-M0+™, advanced power management functionality, a cryptographic security engine, analog and digital peripherals, a software configurable protocol engine with a radio that supports Bluetooth® LE (qualified against Bluetooth Core 5.3) and 256KB of embedded flash accompanied by 96KB of RAM, 16KB of cache RAM, and 288KB ROM (containing the Bluetooth Low Energy (LE) stack). The embedded flash or SRAM may be expended externally through QSPI.
The DA1459x family offers the lowest power consumption in its class and the DA14594 also offers ‘Locationing 2.0’ customers the lowest power and lowest cost SoC for implementing Asset Tracking and Locationing At Scale (ATLAS) Angle of Arrival (AoA) Tags and Wireless Ranging (WiRa™) phase-based ranging Responders.
The DA14594 is based on an Arm Cortex-M33 CPU with an 8-region MPU and a single-precision FPU offering up to 96dMIPS at 64MHz. The dedicated application processor executes code from embedded flash or RAM via an 8KB 4-way associative cache controller. The authenticity and integrity of Bluetooth connectivity is guaranteed by a new software-configurable Cipher-based Message Authentication Code (CMAC) implementation based on an Arm Cortex-M0+ with an ultra-low-power radio transceiver, capable of +6dBm output power and -97dBm sensitivity offering a total link budget of 103dB.
A variety of standard and advanced peripherals enable interaction with other system components and the development of advanced user interfaces and feature-rich applications.
