Renesas Electronics DA14594 SmartBond Dual-Core BLUETOOTH® LE 5.3 SoC
Renesas DA14594 SmartBond™ Dual-Core BLUETOOTH® LE 5.3 SoC is a dual-core wireless microcontroller that combines the current Arm® Cortex®-M33™ application processor. This processor has a floating-point unit, Cortex-M0+™, advanced power management functionality, a cryptographic security engine, and analog and digital peripherals. It also includes a software configurable protocol engine with a radio that is compliant with the Bluetooth 5.3 Low Energy (LE) standard and 256KB of embedded Flash accompanied by 96KB of RAM, 16KB of cache RAM, and 288KB ROM (containing the Bluetooth 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 Renesas 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. Bluetooth 5.3 or other protocol connectivity is guaranteed by avoiding using a software-configurable Bluetooth Low Energy protocol engine (CMAC) 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.
Various standard and advanced peripherals enable interaction with other system components and the development of advanced user interfaces and feature-rich applications.
