DESCRIPTION
Custom applications can be executed on an efficient 32-bit ARC processor from a 512kB flash using a cache and DMA to optimize power. DSP and floating-point units can be exploited to implement advanced audio and tracking algorithms. Low-power serial interfaces (SPI, I2C, I2S, and UART) can be used to talk with external sensors, memory, display, or touch drivers. In addition, EM9305 can directly be connected to a USB port of a PC. Included in the software is a fully featured Bluetooth® LE link layer, Host Controller Interface (HCI), stack, profiles and services, and firmware over-the-air (FOTA) updating capability. All Bluetooth® Core 5.4 features are available on the EM9305, including LE 2M and LE Coded communication, Direction Finding for localization applications. Isochronous channels are also available for LE Audio applications. The EM9305 includes a sophisticated on-chip power management system supporting 1.5V or 3V batteries, and it can be directly powered from an attached 5V USB port.
