DA14682 Datasheet | Renesas

description - Integrated Buck DC-DC converter (1.7 V - 4.75 V) The DA14682 is a flexible System-on-Chip bining an application processor, memories, cryptography engine, power management unit, digital and analog peripherals and a Bluetooth Low Energy MAC engine and radio transceiver. - Three power supply pins for external devices - Supports Li-Polymer, Li-Ion, coin, Ni MH and alka- line batteries - Charger (up to 5.0 V) with programmable curves - High accuracy state-of-charge fuel gauge - Programmable threshold for brownout detection The DA14682 is based on an Arm® Cortex®-M0 CPU - Digitally controlled oscillators and PLL delivering up to 84 DMIPS (at maximum 96 MHz sys- - 16/32 MHz crystal oscillator tem speed) and provides a flexible memory architec- - 16 MHz RC oscillator ture, enabling code execution from embedded memory - 32 k Hz crystal and RC oscillator (RAM, ROM) or non-volatile memory (OTP or internal- - 11.4 k Hz RCX oscillator Quad-SPI FLASH). - Low power PLL up to 96 MHz The advanced power management unit of the DA14682 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 allow the DA14682 to natively charge rechargeable batteries over USB. - Three general purpose timer/counters with PWM - One 16-bit up/down timer/counter with PWM available in extended/deep sleep mode - Application cryptographic engine with ECC, AES256, SHA-1, SHA-256, SHA-512 and True Random Number Generator - Digital interfaces The DA14682 es with enhanced security features - 31 general purpose I/Os with programmable volt- such as key manipulation, secure booting, starting the age levels system only if the FLASH image is authenticated, a - Two UARTs, one with hardware flow control plete public/private hardware acceleration engine - Two SPI+™ interfaces and a true random number generator (TRNG). - Two I2C bus interfaces at 100 k Hz, 400 k Hz Several optimised sleep...
