DA1469x
Multi-Core Bluetooth® 5.2 SoC Family with System PMU
Final
General Description
The DA1469x is a family of multi-core wireless microcontrollers, combining the latest Arm® Cortex®M33 application processor with floating-point unit, advanced power management functionality, a cryptographic security engine, analog and digital peripherals, a dedicated sensor node controller, and a software configurable protocol engine with a radio that is compliant to the Bluetooth® 5.2 low energy standard.
The DA1469x is based on an Arm Cortex-M33 CPU with an 8-region MPU and a single-precision FPU offering up to 144 dMIPS. The dedicated application processor executes code from embedded memory (RAM) or external QSPI FLASH via a 16 kB 4-way associative cache controller, which is equipped with an on-the-fly decrypting capability without extra wait states. Bluetooth® 5.2 connectivity is guaranteed by a new software-configurable Bluetooth® low energy protocol engine (MAC) with an ultra-low-power radio transceiver, capable of +6 dBm output power and -97 dBm sensitivity offering a total link budget of 103 dB.
An optimized programmable sensor node controller allows sensor node operations and data acquisition without CPU intervention, achieving best-in-class power consumption.
The advanced power management unit of the DA1469x enables it to run on primary and secondary batteries, as well as provide power to external devices through the integrated SIMO DCDC and integrated LDOs. The on-chip JEITA-compliant hardware charger makes it possible to natively charge rechargeable batteries over USB.
A variety of standard and advanced peripherals enable interaction with other system components and the development of advanced user interfaces and feature-rich applications.
