DA14695-00000HQ2

The DA1469x is a family of multi-core wireless microcontrollers, combining the latest ARM Cortex
M33TM 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® 5.1 low
energy standard.
The DA1469x is based on an ARM Cortex-M33TM 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 5.1 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 102 dBm.
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.
