Renesas DA14695-00HQDEVKT-P

Overview

DA14695-00HQDEVKT-P from Renesas Electronics is a multi-core Bluetooth 5.2 System-on-Chip integrating an Arm® Cortex®-M33 application processor (96 MHz, 144 dMIPS), dedicated sensor node controller (SNC), software-configurable Bluetooth LE MAC engine, +6 dBm radio transceiver (-97 dBm sensitivity), and integrated SIMO DC-DC + JEITA-compliant USB charger - designed for ultra-low-power wearable and battery-constrained edge devices like smartwatches and fitness trackers.

For engineers reviewing the DA14695-00HQDEVKT-P datasheet, DA14695-00HQDEVKT-P pinout, DA14695-00HQDEVKT-P application, or DA14695-00HQDEVKT-P equivalent, key selection considerations include its VFBGA86 package, dual ADC subsystem (10-bit SAR @ 3.4 Msps + 14-bit ΣΔ @ 1 ksps), on-the-fly QSPI decryption, hardware TRNG, and support for haptic/LED drivers in space-constrained rechargeable systems.

Technical Context

The DA14695-00HQDEVKT-P implements a heterogeneous multi-core architecture: the Cortex-M33 executes application firmware with 16 kB 4-way associative cache and FPU, while the autonomous Sensor Node Controller (SNC) handles sensor data acquisition without CPU wake-up. Its software-configurable CMAC engine offloads BLE protocol stack processing up to HCI layer, decoupling radio timing from application execution.

Power management is centralized via the System PMU, featuring a SIMO buck converter (2.4–4.75 V), four always-on power supply pins, hardware brownout detection, and a JEITA-compliant USB charger supporting Li-Po, Li-Ion, coin cell, NiMH, and alkaline batteries - enabling native battery charging and retention across deep sleep modes (Hibernation, Extended Sleep).

FAQ

What is the package type and ball pitch of the DA14695-00HQDEVKT-P?

The DA14695-00HQDEVKT-P uses a VFBGA86 package measuring 6 mm × 6 mm with a 0.55 mm ball pitch. This compact footprint is optimized for space-constrained wearables and supports fine-pitch PCB assembly. The DA14695-00HQDEVKT-P is mechanically and electrically distinct from the VFBGA100 variant, and pin compatibility between the two packages is not supported.

Does the DA14695-00HQDEVKT-P support secure boot and cryptographic operations?

Yes, the DA14695-00HQDEVKT-P includes a dedicated application cryptographic engine supporting AES-256, SHA-1/256/512, and a FIPS 140-2-compliant True Random Number Generator (TRNG). Secure boot is enforced via ROM-based PKI routines that authenticate Flash images using keys stored in OTP memory - ensuring firmware integrity from power-on reset.

Can the DA14695-00HQDEVKT-P operate directly from a USB-C port for both power and charging?

Yes, the DA14695-00HQDEVKT-P integrates a JEITA-compliant hardware USB charger capable of accepting 5 V input and charging Li-Po/Li-Ion batteries up to 4.2 V with programmable current/voltage curves. It performs contact detection, primary/secondary charger identification, and thermal regulation - enabling direct USB-C connection without external charge ICs.

What is the role of the Sensor Node Controller (SNC) in the DA14695-00HQDEVKT-P?

The Sensor Node Controller (SNC) in the DA14695-00HQDEVKT-P is a programmable uCode-based coprocessor that autonomously handles sensor data acquisition, filtering, and threshold-triggered actions - all without waking the Cortex-M33 core. This reduces average system current by up to 95% during periodic sensing tasks such as step counting or ambient light monitoring.

How does the DA14695-00HQDEVKT-P achieve ultra-low-power hibernation?

The DA14695-00HQDEVKT-P achieves sub-1.5 µA hibernation current by powering down the Cortex-M33, cache, and most peripherals while retaining SRAM content and RTC operation. Its System PMU maintains four independent I/O power rails (VDDIO_0–3) in hibernation, allowing external sensors or buttons to wake the device - a capability confirmed in Renesas R18DS0049EE0340 Section 6.4.
