Microchip Technology ATTINY861A-SU

The ATTINY861A-SU is a high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combining 8KB ISP flash memory, 512-Byte EEPROM, 512-Byte SRAM, 16 general purpose I/O lines, 32 general purpose working registers, a wide range of peripherals, and a serial programmable USART. The device is packaged in a compact 20-SOIC form factor, making it suitable for space-constrained applications.

With its advanced RISC architecture, the ATTINY861A-SU enables throughput approaching 1 MIPS per MHz, balancing power consumption and processing speed. It operates between 1.8-5.5 volts, allowing the use in varying power supply conditions, and features a variety of power-saving modes which further extend battery life in portable applications.

The microcontroller's memory endurance is enhanced by the picoPower technology, which ensures high endurance and non-volatility. The ISP flash memory can be accessed by SPI, enabling simple in-system programming, which is facilitated by software such as Atmel Studio and the Atmel-ICE debugger. This feature allows for firmware updates in the field without the need to remove the microcontroller from its application.

Peripheral features include an 8-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, three flexible timer/counters with compare modes, internal and external interrupts, a serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, and five software selectable power saving modes. These features make the ATTINY861A-SU a versatile choice for a wide range of applications, from industrial control systems to power management solutions.

Furthermore, the ATTINY861A-SU supports QTouch® Library, which makes it possible to implement capacitive touch sensing interfaces, providing a cost-effective way to add touch interfaces without the need for additional hardware.

Overall, the Microchip ATTINY861A-SU is a robust microcontroller that offers a rich feature set while maintaining low power consumption, making it an excellent choice for designers looking to optimize their embedded systems.
