ATTINY13-20MMUR

Overview

The ATTINY13-20MMUR is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features a high-performance, low-power architecture with up to 20 MIPS throughput at 20 MHz. The device includes 1 KByte of In-System Programmable Flash, 64 Bytes EEPROM, and 64 Bytes Internal SRAM. It operates within a voltage range of 2.7 V to 5.5 V and supports industrial temperature ranges from -40°C to +85°C. The component is housed in a 10-pad MLF package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Integrated 4-channel, 10-bit ADC with internal voltage reference
• On-chip debug system supporting in-system programming via SPI port
• Multiple software selectable power saving modes including idle and power-down

Applications

• Battery-powered consumer devices requiring low power consumption
• Industrial control systems operating in harsh environments
• Simple sensor interfaces utilizing the integrated analog-to-digital converter

Procurement Notes

Verify the specific speed grade and voltage requirements against the application needs before procurement. Confirm that the 10-pad MLF package dimensions align with the PCB layout constraints. Ensure that the ordering suffix matches the required tape and reel packaging format for automated assembly processes.

Selection Notes

Select this component when a compact footprint and low power consumption are critical design factors. Consider the limited I/O count and memory size relative to the complexity of the intended firmware logic. Evaluate the need for the on-chip debug capabilities if development efficiency is a priority over final unit cost.

Part Context

This part belongs to the ATtiny13 family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares core functionalities with other variants in the series but differs in package type and speed grades. The MMUR suffix indicates a specific surface-mount package configuration suitable for space-constrained designs.

Replacement Considerations

Direct substitutes include other ATtiny13 variants such as ATTINY13-20MU or ATTINY13A-20MMU, provided the pinout and electrical specifications remain compatible. Verify that any replacement maintains the same package dimensions and thermal characteristics.
