AT32WB415 embeds a low-power radio that is compliant with Bluetooth Low Energy SIG specification 5.0. It contains rich communication interfaces, Bluetooth radio frequency (RF) transceiver and baseband features, delivering robust wireless data signal processing capability, with up to -97 dBm sensitivity in Bluetooth RX, and -20 dBm ~ +4 dBm in Bluetooth TX. The antenna embedded in the device can cover as far as 30m, up to 2Mbps, for powerful connectivity.
The device is based on ARM®Cortex®-M4 core operating at a frequency of up to 150 MHz. It integrates a digital signal processor (DSP) and memory protection unit (MPU), up to 256 KB Flash memory and 32 KB SRAM. The device also incorporates a Security Library (sLib) developed by ARTERY, allowing users to program any part of the internal Flash memory protected by such mechanism. This security library is code-executable but non-readable, making it more secure for the solution providers to write core algorithm in it, but also be more convenient for them to carry out second-level development. It features a comprehensive range of peripherals, namely 1x 12-bit 8-channel ADC, 2x CMPs, 4x UARTs, 1x SPI, 1x I2C, 1x CAN, 1x advanced timer and 7x general-purpose timers. The AT32WB415 series operates in the temperature range of -40 to 105oC. Compared to legacy MCUs, in which functions are relatively scattered, AT32WB415 provides an all-in-one solution for the development of Bluetooth technology products. Besides, its reduced PCB size and the optimized RF layout will bring more excellent solutions for various applications such as consumer electronics, smart home, Internet of Things (IoT), among others.
