FAQ

What is the maximum system clock frequency supported by the DA14683-00000A92?

The DA14683-00000A92 supports a maximum system clock frequency of 96 MHz using its low-power PLL, delivering 86 DMIPS performance from the ARM Cortex-M0 core. This frequency is achievable with the internal 16 MHz crystal oscillator and PLL configuration, and is validated across voltage (1.7–4.75 V) and temperature (–40°C to +85°C) ranges per Renesas datasheet Rev 3.5.

Does the DA14683-00000A92 support secure boot and cryptographic key protection?

Yes, the DA14683-00000A92 implements hardware-enforced secure boot that validates the authenticity of the FLASH image before execution, plus dedicated cryptographic accelerators for AES-256, ECC (NIST P-256/P-384), SHA-256/512, and a True Random Number Generator (TRNG). Keys are manipulated in secure memory regions inaccessible to software, satisfying requirements for device attestation and encrypted OTA updates.

What power supply configurations does the DA14683-00000A92 support for battery operation?

The DA14683-00000A92 supports direct connection to Li-Polymer, Li-Ion, NiMH, alkaline, and coin-cell batteries via its VBAT1 (1.7–4.75 V) and VBAT2 inputs. Its integrated buck DC-DC converter and three LDOs (CORE, SLEEP, IO) enable efficient multi-rail regulation. The on-chip fuel gauge provides high-accuracy state-of-charge estimation without external components.

Can the DA14683-00000A92 operate in hibernation mode while retaining RAM and waking on external interrupt?

Yes, the DA14683-00000A92 supports hibernation mode with 800 nA typical current draw while retaining full 128 kB SRAM content and enabling wake-up via GPIO, RTC alarm, or USB event. This mode preserves application context across extended idle periods - essential for battery-powered devices requiring instant responsiveness after months of dormancy.

What is the RF performance specification of the DA14683-00000A92 BLE transceiver?

The DA14683-00000A92 BLE transceiver delivers 0 dBm nominal transmit output power and –94 dBm receiver sensitivity at 1 Mbps BLE PHY, measured at VBAT1 = 3.0 V with ideal DC-DC converter. It complies with Bluetooth 5.0, FCC Part 15, ETSI EN 300 328, and ARIB STD-T66 standards, and features an integrated balun with 50 Ω single-wire antenna interface.
