ATTINY13A-MUR

Overview

The ATTINY13A-MUR is an 8-bit AVR microcontroller featuring a 20-pad WQFN package. It integrates 1K bytes of In-System Programmable Flash, 64 bytes EEPROM, and 64 bytes SRAM. The device supports a maximum clock frequency of 20 MHz with operating voltages ranging from 1.8V to 5.5V. Key peripherals include a 4-channel 10-bit ADC, an 8-bit Timer/Counter with two PWM channels, and an on-chip analog comparator. It operates within the industrial temperature range.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Non-volatile memory segments offering high endurance with self-programmable Flash and EEPROM capabilities.
• Integrated peripheral suite including a 10-bit ADC, analog comparator, and programmable watchdog timer.
• Supports low-power operation through selectable Idle, ADC Noise Reduction, and Power-down modes.

Applications

• Battery-powered embedded systems requiring low voltage operation
• Industrial control applications within specified temperature ranges
• Simple sensor interfaces utilizing internal ADC and analog comparator

Procurement Notes

Verify the specific suffix MUR corresponds to the 20-pad WQFN package configuration as defined in Microchip ordering information. Confirm that the industrial temperature grade matches the intended environmental operating conditions. Ensure compatibility with existing PCB footprints designed for the 20-lead thin quad flat no-lead form factor.

Selection Notes

Select this component when a compact 20-pin footprint is required alongside standard ATtiny13A functionality. Consider the trade-off between increased pin count availability and board space constraints compared to 8-pin or 10-pin variants. Evaluate power consumption requirements against the available sleep modes for battery longevity.

Part Context

This part belongs to the ATtiny13A family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares the same core CPU architecture and peripheral set as other package variants like SSU or MMU, differing primarily in physical packaging and pin configuration to suit different assembly needs.

Replacement Considerations

Direct replacements include ATTINY13A-MMU (10-VDFN) and ATTINY13A-SSU (8-SOIC). Verify pinout compatibility and mechanical dimensions before substitution, as package differences may require PCB redesign or adapter usage.
