Product details
Overview
DA14531MOD-00F1DB-P from Renesas Electronics is an ultra-low power Bluetooth 5.1 System-on-Chip integrating a 2.4 GHz transceiver, Arm® Cortex-M0+ core (16 MHz), 48 kB retainable RAM, 32 kB OTP memory, and hardware-accelerated Link Layer/AES-128 encryption. It serves as a standalone application processor or data pump in hosted BLE systems, deployed in disposable medical sensors and proximity tags.
For engineers reviewing the DA14531MOD-00F1DB-P datasheet, DA14531MOD-00F1DB-P pinout, DA14531MOD-00F1DB-P application, or DA14531MOD-00F1DB-P equivalent, key selection criteria include cold boot time (35 ms), hibernation current (270 nA buck / 240 nA boost), -94 dBm RX sensitivity, programmable TX power (-19.5 to +2.5 dBm), and FCGQFN24 package compatibility.
Technical Context
The DA14531MOD-00F1DB-P implements Bluetooth LE 5.1 with dedicated hardware Link Layer engine and certified stack supporting GAP, GATT, ATT, SM, and L2CAP - enabling concurrent connections up to three. Its dual-power architecture integrates configurable buck (1.8–3.6 V) and boost (1.1–1.65 V) DC-DC converters for operation across primary and coin-cell battery sources.
Timing control combines 32 MHz crystal/RC oscillators and a 15 kHz RCX crystal-replacement oscillator, while system responsiveness is enhanced by clock-less hibernation wake-up and two general-purpose timers with PWM/capture capability. The device supports UART (with flow control), SPI Master/Slave (up to 32 MHz), I²C (100/400 kHz), and 4-channel 10-bit ADC for sensor interfacing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Bluetooth LE SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Nordic nRF52805-QFAA | ARM Cortex-M4F core, 192 kB flash, no integrated DC-DC; requires external regulator; 2.4 GHz radio only (no proprietary protocols) | Higher compute throughput but larger footprint (32-pin QFN); lacks crystal-less hibernation and boost converter for coin cells | Select when floating-point math or larger firmware is required; avoid if coin-cell operation or minimal BOM is critical. |
| Texas Instruments CC2642R1RGER | ARM Cortex-M4F + dedicated Sensor Controller; 352 kB flash; integrated DC-DC; supports BLE 5.0 (not 5.1 direction finding) | Superior analog integration (12-bit ADC, DAC, op-amps); higher TX power (+5 dBm); larger 24-pin VQFN but no WLCSP option | Select for sensor-rich designs needing analog signal conditioning; avoid if Bluetooth 5.1 Angle of Arrival/Angle of Departure features are mandatory. |
Compared with nRF52805-QFAA and CC2642R1RGER, DA14531MOD-00F1DB-P delivers the lowest system-level power (240 nA hibernation), smallest FCGQFN24 footprint, and native BLE 5.1 direction-finding readiness - making it optimal for cost-sensitive, battery-constrained peripherals where minimal bill-of-materials and long shelf life are design priorities.

FAQ
What is the package type and pin count of DA14531MOD-00F1DB-P?
DA14531MOD-00F1DB-P uses a 24-pin FCGQFN package (2.2 × 3.0 mm, 0.4 mm pitch) with exposed thermal pad. This matches the DA14531-00 variant's pinout and supports all 12 GPIOs, dual UART, SPI, I²C, and RF antenna interface. The "F1DB" suffix confirms FCGQFN24 packaging per Renesas' part numbering convention.
Does DA14531MOD-00F1DB-P support Bluetooth 5.1 Direction Finding?
Yes, DA14531MOD-00F1DB-P fully complies with Bluetooth 5.1, including Angle of Arrival (AoA) and Angle of Departure (AoD) features. Its hardware-accelerated Link Layer and certified stack implement the required CTE (Constant Tone Extension) transmission and sampling capabilities, enabling precise indoor positioning when paired with compatible infrastructure.
Can DA14531MOD-00F1DB-P operate from a single coin-cell battery?
Yes, DA14531MOD-00F1DB-P supports coin-cell operation via its integrated boost converter, which accepts input voltages from 1.1 V to 1.65 V. In boost mode, it achieves 240 nA hibernation current and maintains full BLE functionality - enabling multi-year operation on CR2032 batteries in applications like proximity tags and medical disposables.
What is the maximum number of concurrent BLE connections supported by DA14531MOD-00F1DB-P?
DA14531MOD-00F1DB-P supports up to three concurrent Bluetooth LE connections - either as a central connecting to multiple peripherals, as a peripheral serving multiple centrals, or mixed-role configurations. This is enabled by dedicated Link Layer hardware and sufficient RAM allocation for connection state management within its 48 kB retainable SRAM.
Is DA14531MOD-00F1DB-P pin-compatible with other DA14531 variants?
DA14531MOD-00F1DB-P is pin-compatible with the DA14531-01 variant in the same FCGQFN24 package, but not with WLCSP17 versions. However, DA14531-00 (this part) and DA14531-01 differ functionally: DA14531MOD-00F1DB-P supports both central and peripheral roles, while DA14531-01 is peripheral-only with +25% user RAM allocation.
