Renesas Debuts Its Lowest Power Consumption, Dual-core Bluetooth Low Energy SoC with Integrated Flash

12.04. 2024 | News

Renesas Electronics introduced the DA14592 Bluetooth® Low Energy (LE) System-on-Chip (SoC) representing Renesas’ lowest power consumption and smallest, multi-core (Cortex-M33, Cortex-M0+), Bluetooth LE device. By carefully balancing tradeoffs between on-chip memory (RAM/ROM/Flash) and SoC die size (for cost), the DA14592 is very well suited to a broad range of applications including connected medical, asset tracking, human interface devices, metering, PoS readers and ‘crowd-sourced location’ (CSL) tracking.

Continuing Renesas’ Bluetooth LE SoC leadership in lowest radio power consumption, the DA14592 utilizes a new low-power mode to offer world-class, 2.3mA radio transmit current at 0dBm and 1.2mA radio receive current. Additionally, it supports an ultra-low hibernation current of only 90nA, extending shelf-life for end-products shipped with ‘battery connected’, and ultra-low active current at 34µA/MHz for products requiring significant application processing.

From a solution cost perspective, the DA14592 typically only requires 6 external components, offering a best-in-class engineering bill of materials (eBOM). Operating from only a system clock and its highly accurate on-chip RCX, this device removes the need for a sleep mode crystal in the majority of applications. Its reduced eBOM, coupled with the DA14592’s small package (offered in WLCSP: 3.32mm x 2.48mm and FCQFN: 5.1mm x 4.3mm) also presents designers with an attractively small solution footprint. The DA14592 also includes a high-precision, sigma-delta ADC, up to 32 GPIOs and unlike other SoCs in its class, it offers a QSPI supporting external memory (Flash or RAM) expansion for applications requiring extra memory (more info).
