DA14683RF/IF射頻/中頻RFID的射頻收發(fā)器IC規(guī)格書(shū)PDF中文資料

General description

The DA14683 is a flexible System-on-Chip combining

an application processor, memories, cryptography

engine, power management unit, digital and analog

peripherals and a Bluetooth Low Energy MAC engine

and radio transceiver.

The DA14683 is based on an ARM? Cortex?-M0 CPU

delivering up to 86 DMIPS (at maximum 96 MHz system speed) and provides a flexible memory architecture, enabling code execution from embedded memory

(RAM, ROM) or non-volatile memory (OTP or external

Quad-SPI FLASH).

The advanced power management unit of the

DA14683 enables it to run from primary and secondary

batteries, as well as provide power to external devices.

The on-chip charger and state-of-charge fuel gauge

allows the DA14683 to natively charge rechargeable

batteries over USB.

The DA14683 comes with enhanced security features

such as key manipulation, secure booting (i.e. starting

the system only if the FLASH image is authenticated),

a complete public/private hardware acceleration

engine and a hardware true random number generator

(TRNG).

Several optimised sleep modes are available to reduce

power dissipation when there is no activity
