The DA14592 from Renesas is a Multi-Core Wireless Bluetooth Low Energy (BLE) 5.2 System-on-Chip (SoC). It consists of the latest ARM Cortex M33 application processor with a floating-point unit (FPU), advanced power management functionality and a cryptographic security engine. This SoC also has analog/digital peripherals, a software configurable protocol engine with a BLE 5.2-compliant radio, and a memory unit (96 KB of RAM, 16 KB of cache RAM, and 288 KB of ROM with embedded flash and Bluetooth LE stack). It requires a DC supply from 1.7 to 3.6 V and consumes 1.52 mA (Active mode) and 481 µA (idle) of current.
The DA14592 utilizes an ARM Cortex M33 CPU with an eight-region FPU that delivers a data rate of up to 96 dMIPS at 64 MHz. It also supports a new software-configurable BLE protocol engine (CMAC), which is based on the ARM Cortex M0+ integrating an ultra-low power radio transceiver. This microcontroller includes a Buck DC-DC converter with programmable thresholds for brownout detection, and a 32/64 MHz system clock using a doubler for efficient power management. It is equipped with a comprehensive set of interfaces such as 32 GPIOs, 10-bit SAR ADCs (at 2 Msamples/s), UARTs, SPI+, and PDM and uses the QSPI interface to further expand the embedded Flash or SRAM unit.
This BLE 5.2 SoC is supported by an application cryptographic engine with AES-256 and SHA-256 for secure communication and control. It has a built-in on-chip RCX that ensures high accuracy and removes the need for an external, sleep mode crystal. It is available in a wafer-level package that measures 3.32 x 2.48 mm and is ideal for S-pen, toys, metering, ESL, activity tracker, beacons, keyboards, robotics, and wearable applications.
