ATTINY461A-MU

The Microchip Technology ATtiny461A is a low-power, high-performance 8-bit AVR microcontroller featuring 4KB of in-system self-programmable Flash memory, 256B of SRAM, and 256B of EEPROM. Its advanced RISC architecture executes 123 powerful instructions in a single clock cycle, achieving up to 20 MIPS throughput at 20 MHz.

Integrated peripheral features include a 10-bit ADC with 11 single-ended channels and 16 differential channel pairs, one 8/16-bit timer/counter with prescaler, one 8/10-bit high-speed timer with prescaler, and three high-frequency PWM outputs with a programmable dead time generator. The device also includes a programmable watchdog timer, brown-out detection, power-on reset, and an internal calibrated oscillator. Communication is handled through a Universal Serial Interface (USI) with start condition detector.

The microcontroller is available in a 32-VFQFN exposed pad package (32-VQFN 5x5mm) for surface mount assembly. It supports a wide operating voltage range of 1.8V to 5.5V and four sleep modes (Idle, ADC Noise Reduction, Standby, Power-Down) for low-power applications. Active power consumption is typically 200 µA at 1 MHz and 1.8V, and power-down current is 0.1 µA.
