The DA14701 from Renesas is a 2.4 GHz Bluetooth 5.2 SoC that supports Bluetooth® low energy as well as other 2.4 GHz protocols. It is based on an Arm Cortex-M33 CPU with an eight-segment Memory Protection Unit (MPU), DSP extensions, and a single-precision Floating Point Unit (FPU) offering up to 240 dMIPS. This SoC integrates advanced power management functionality, a Graphics Processing Unit (GPU) for advanced graphics processing, a cryptographic security engine, analog, and digital peripherals, a dedicated sensor node controller, and a software configurable protocol engine with a radio that is compliant with the Bluetooth® 5.2 low energy standard.
The DA14701 can be controlled via GPIO, SPI, UART, MIPI I3C, I2C, PDM, PCM, and USB 1.1 interfaces. It has 1.5 MB Data SRAM with retention, 4 kB OTP memory, 8 kB ICache SRAM, 8 kB DCache SRAM, and 32 KB ROM. This SoC has a dedicated application processor that executes code from an external Octa/Quad SPI FLASH device equipped with an on-the-fly decrypting engine via an 8 kB four-way set associative instruction cache controller. It has a software-configurable Bluetooth® low energy protocol engine (MAC) with an ultra-low-power radio transceiver, capable of +6 dBm output power, and -97 dBm sensitivity offering a total link budget of 103 dB.
This SoC is available in a VFBGA142 package that measures 6.2 x 2.0 mm and is ideal for use in fitness trackers, sports watches, smartwatches, consumer medical devices, consumer and home appliances, home automation, gaming consoles, industrial automation and security systems applications.
