ATTINY461A-MUR 8-bit microcontroller
The ATTINY461A-MUR is a low-power, high-performance 8-bit microcontroller from Microchip Technology (formerly Atmel), based on the AVR enhanced RISC architecture. Housed in a compact 32-pin VQFN package with exposed thermal pad, this device features 4KB of In-System Self-Programmable Flash memory, 256 bytes of EEPROM, and 256 bytes of SRAM. Operating at speeds up to 20 MHz (20 MIPS throughput) with a wide 1.8V to 5.5V supply range, it achieves exceptional code efficiency by executing most instructions in a single clock cycle. The device maintains robust performance across the industrial temperature range of -40°C to +85°C, making it ideal for power-sensitive embedded applications requiring analog precision and compact form factors.
AVR ATtiny MCU Selection Advantages
The ATTINY461A-MUR offers compelling advantages for designers seeking optimal balance between performance, power efficiency, and compact footprint. The 4KB Flash memory provides ample code space for moderately complex applications, while the 256B EEPROM offers sufficient non-volatile storage for calibration data and configuration parameters without external memory. The integrated 10-bit ADC with differential inputs and programmable gain eliminates external instrumentation amplifiers for many sensor applications, reducing BOM cost and PCB complexity. The wide 1.8V–5.5V operating range accommodates single-cell Li-ion battery operation (down to 1.8V) while maintaining compatibility with 5V legacy systems. Four software-selectable sleep modes (Idle, ADC Noise Reduction, Power-down, Standby) enable fine-grained power management, with power-down mode consuming merely 0.1μA for years of battery standby.
Alternative Compatible Microcontrollers
● ATTINY261A-MUR: Lower-density variant with 2KB Flash and 128B EEPROM/SRAM for cost-sensitive applications with reduced code requirements in identical VQFN-32 package.
● ATTINY861A-MUR: Higher-density version with 8KB Flash and 512B EEPROM/SRAM for complex applications requiring expanded memory and identical pinout for seamless migration.
● ATTINY461A-SU: SOIC-20 packaged variant sharing identical electrical characteristics for applications preferring standard surface-mount assembly and easier prototyping.
● ATTINY461A-XU: TSSOP-20 package option offering reduced footprint with same 4KB Flash and analog peripherals for space-constrained designs.
● ATMEGA48PA-MU: Higher-performance alternative with 4KB Flash, 512B SRAM, and additional USART/SPI/TWI interfaces in QFN-28 for applications requiring enhanced connectivity.
● PIC16F18313-I/MQ: Microchip's enhanced mid-range 8-bit MCU with 3.5KB Flash and 256B SRAM offering similar power efficiency with different architecture for supply chain diversification.
