ATTINY461-20SUR Description

Short technical summary and product information.

The ATTINY461-20SUR is a high-performance 8-bit AVR microcontroller from Microchip Technology, designed for embedded control applications requiring low power consumption and a compact footprint. It features a 4KB Flash program memory, 256 bytes of SRAM, and 256 bytes of EEPROM, providing ample storage for small to medium applications. The core operates at speeds up to 20MHz, delivering up to 20 MIPS throughput.

 

This microcontroller includes 16 general-purpose I/O lines, an 11-channel 10-bit ADC, and a Universal Serial Interface (USI) for serial communication. Peripherals include brown-out detection, power-on reset, PWM, and a watchdog timer, enhancing system reliability. The device supports an internal oscillator and operates over a supply voltage range of 2.7V to 5.5V, with a higher voltage range of 4.5V to 5.5V required for 20MHz operation.

 

Packaged in a 20-pin SOIC (0.295" width, 7.50mm body) with gull-wing leads and 1.27mm pitch, the ATTINY461-20SUR is suitable for surface mount assembly. The operating temperature range is -40°C to 85°C, making it appropriate for industrial and consumer environments. Typical active current at 1MHz is 300µA, and power-down current is as low as 0.1µA, enabling battery-powered designs.
