Renesas DA14580DEVKT-B

Overview

DA14580DEVKT-B from Renesas Electronics is a Bluetooth Low Energy 4.2 development kit based on the DA14580 SoC, integrating ARM Cortex-M0 processor, BLE Link Layer hardware accelerator, 32 kB OTP, 42 kB SRAM, and fully compliant 2.4 GHz transceiver with -93 dBm sensitivity and 0 dBm output power. It enables rapid prototyping of battery-powered wearable sensors and smart peripherals.

For engineers reviewing the DA14580DEVKT-B datasheet, DA14580DEVKT-B pinout, DA14580DEVKT-B application, or DA14580DEVKT-B equivalent, this kit provides pre-certified RF layout, onboard SWD debug interface, UART-to-USB bridge, and firmware-ready hardware for BLE sensor node development, OTA update validation, and power profiling.

Technical Context

The DA14580DEVKT-B implements a complete evaluation platform for the DA14580 SoC, featuring a QFN48-packaged IC with 24 GPIOs, dual UART (1 MBd), SPI+, I²C, 4-channel 10-bit ADC, and quadrature decoder. Its power architecture includes integrated buck/boost DC-DC converter supporting coin (3.0 V) or alkaline (1.5 V) batteries, with measured TX/RX current of 3.4 mA / 3.7 mA at VBAT3V.

Hardware-level BLE protocol acceleration is provided by dedicated Link Layer processor and AES-128 encryption engine, while system timing uses dual crystal oscillators (16 MHz ±20 ppm, 32.768 kHz ±50 ppm) plus RC alternatives. The kit exposes all critical RFIO pins, reset, SWD, and power domains for full functional and RF characterization.

FAQ

What is the DA14580DEVKT-B used for?

The DA14580DEVKT-B is a complete evaluation kit for the DA14580 Bluetooth Low Energy 4.2 SoC. It provides a ready-to-run hardware platform with onboard debugger, USB-to-UART bridge, and reference antenna layout to validate firmware, measure power consumption, test RF range, and develop BLE applications such as fitness trackers, medical sensors, and smart tags. DA14580DEVKT-B includes all necessary jumpers, LEDs, and test points for full functional verification.

Does the DA14580DEVKT-B include the DA14580 SoC in QFN48 package?

Yes, the DA14580DEVKT-B integrates the DA14580 SoC in QFN48 package (6 mm × 6 mm), providing access to all 48 pins including RFIOp/RFIOm, XTAL16Mp/XTAL16Mm, SWDIO/SW_CLK, and 24 GPIOs. This matches the DA14580-01A31 production part and enables direct correlation between evaluation results and final PCB layout.

Can the DA14580DEVKT-B support over-the-air (OTA) firmware updates?

Yes, the DA14580DEVKT-B supports OTA firmware updates via BLE using the qualified Bluetooth stack stored in ROM and customer application code stored in OTP or SRAM. The DA14580 SoC's flexible memory architecture and built-in bootloader enable secure, field-upgradable firmware without physical reprogramming. DA14580DEVKT-B includes example projects demonstrating OTA update workflows.

What power sources does the DA14580DEVKT-B accept?

The DA14580DEVKT-B accepts either a 3.0 V coin cell (connected to VBAT3V) or 1.5 V alkaline/NiMH battery (connected to VBAT1V), leveraging the DA14580's integrated buck/boost DC-DC converter. Onboard voltage regulation ensures stable 1.0 V core and 3.3 V I/O rails across battery discharge curves, enabling accurate low-power mode testing down to 0.9 V input.

Is the DA14580DEVKT-B RoHS and REACH compliant?

Yes, the DA14580DEVKT-B conforms to RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. All components-including the DA14580 SoC, USB bridge IC, passive RF network, and PCB-meet lead-free soldering requirements and hazardous substance restrictions.
