ATSAML10E16A-AF Application Field and Working Principle

The ATSAML10E16A-AF is a microcontroller designed with embedded applications in mind. This 32-bit microcontroller features an ARM Cortex-M23 microprocessor and an integrated rich analog front ends (AFE) hardware. It is an ideal choice for applications requiring an array of sensors, real-time processing, and low-power consumption. It can be used for a wide range of tasks such as motor control, consumer products, medical devices, and automotive applications.

Overview of Features

The ATSAML10E16A has a Cortex-M23 core clocked at up to 32 MHz, along with 1MB of Flash and 512KB of SRAM. It also features an 8-bit Parallel Interface Module (PIM) and an ARM mbed OS ready software library. Further, it has an ARM CryptoCell 310 and provides hardware encryption and decryption. It also supports an advanced event-controlled power and clock manager (PCM) with low-power modes, allowing it to consume only 47μA/MHz.

The integrated rich AFE hardware allows the ATSAML10E16A to sample a variety of analog sensors with its 10 analog channels, each capable of sample rates of up to 400ksps, and with an ADC resolution of 12-bit up to 14-bit. This makes it a great choice for applications with high precision analog sensing needs.

Communication Interfaces

The ATSAML10E16A has comprehensive communication capabilities, supporting multiple physical layers. It comes with three Serial Peripheral Interface (SPI) buses, two Inter-Integrated Circuit2-wire (I2C) buses, two Universal Asynchronous Receiver/Transsmitters (UARTs). The powerful Universal Serial Interface 2 (USART 2) provides 4 Mbps data rate for reliable communication, coupled with three GPIO pins for full-duplex asynchronous communication.

Further, the ATSAML10E16A features an IEEE 802.15.4 communication module, allowing it to communicate with other networked devices such as Zigbee, 6LoWPAN, and IPv6. The controller also supports a variety of widely used low-power wireless standards, including Bluetooth 5, Thread, and Zigbee IP.

Platform Bus Support

The ATSAML10E16A supports several popular platform buses, such as JTAG, SWD, and On-Board Trace. The JTAG port provides program/debug/test access, while the SWD port provides parallel programmability including reads and writes to RAM and Flash, as well as breakpoint support. The On-Board Trace interface provides real-time debugging and profiling with up to 16kB trace memory.

Power Management and Low Power Capabilities

The ATSAML10E16A has an advanced power management system that allows it to achieve very impressive levels of power consumption. The integrated power management features allow the microcontroller to enter low-power sleep and idle modes, along with active modes, depending on the tasks required. This allows for better power performance and improved battery life for a variety of low-power applications. In addition, an innovative idle external memory mode allows the controller to move to an ultra-low power state for applications that do not require external memory.

Robust Security Features

The ATSAML10E16A features ARM CryptoCell 310, a dedicated secure hardware module that performs tamper detection, authentication, key-exchange, and encryption/decryption at the same time. This makes it ideal for secure IoT applications where data privacy and fraud detection is a major concern. The controller supports a secure bootloader with NVM protection, allowing users to verify system integrity before application execution.

The ATSAML10E16A also has an AES encryption engine, allowing secure wireless connectivity. It supports a full range of transport layer protocols, including TLS, IPsec, and DTLS, and is compliant with the IEEE 802.15.4-2006 standard.

Conclusion

The ATSAML10E16A is an efficient, low-power microcontroller with a rich array of features and capabilities. It provides multiple communication interfaces, a powerful Cortex-M23 processor, and an onboard secure hardware module for secure IoT applications. The integrated rich AFE hardware allows for high-precision analog sensing, and the integrated power management system allows for efficient power consumption. All these features make the ATSAML10E16A an ideal solution for a wide range of embedded applications.
