DA14581 Datasheet | Renesas

Description - AES-128 bit encryption Processor The DA14581 integrated circuit is an optimized version of the DA14580, offering a reduced boot time and supporting up to 8 connections. It has a fully integrated radio transceiver and baseband processor for Bluetooth® low energy. It can be used as a standalone application processor or as a data pump in hosted systems. - Memories - 32 k B One-Time-Programmable (OTP) memory - 42 k B System SRAM - 84 k B ROM - 8 k B Retention SRAM - Power management - Integrated Buck/Boost DC-DC converter - P0, P1 and P2 ports with 3.3 V tolerance The DA14581 supports a flexible memory architecture - Easy decoupling of only 4 supply pins for storing Bluetooth profiles and custom application - Supports coin (typ. 3.0 V) and alkaline (typ. 1.5 V) code, which can be updated over the air (OTA). The battery cells L qualified Bluetooth low energy protocol stack and the - 10-bit ADC for battery voltage measurement HCI ready software are stored in a dedicated ROM. All software runs on the ARM® Cortex®-M0 processor via - Digital controlled oscillators - 16 MHz crystal (±20 ppm max) and RC oscillator IA a simple scheduler. - 32 k Hz crystal (±50 ppm, ±500 ppm max) and The Bluetooth low energy firmware includes the L2CAP service layer protocols, Security Manager T (SM), Attribute Protocol (ATT), the Generic Attribute Profile (GATT) and the Generic Access Profile (GAP). All profiles published by the Bluetooth SIG as well as N custom profiles are supported. RCX oscillator - General purpose, Capture and Sleep timers - Digital interfaces - Gen. purpose I/Os: 14 (WLCSP34), 24 (QFN40) - 2 UARTs with hardware flow control up to 1 MBd - SPI+™ interface - I2C bus at 100 k Hz, 400 k Hz The transceiver interfaces directly to the antenna and - 3-axes capable Quadrature Decoder E is fully pliant with the Bluetooth 4.2 standard. - Analog interfaces The DA14581 has dedicated hardware for the Link ID Layer implementation of Bluetooth low energy and...
