ATTINY13A-MMUR

Overview

The ATTINY13A-MMUR is an 8-bit AVR microcontroller manufactured by Microchip Technology, featuring a 1 KB system-in-programmable Flash memory, 64 bytes of EEPROM, and 64 bytes of SRAM. It operates with a maximum clock frequency of 20 MHz and supports a supply voltage range from 1.8 V to 5.5 V. The device utilizes a 10-MLF (VDFN) package and provides six programmable I/O lines. Key peripherals include a 4-channel 10-bit ADC, an 8-bit timer/counter with two PWM channels, and an on-chip analog comparator.

Feature Summary

• High-performance 8-bit AVR RISC architecture delivering up to 20 MIPS throughput at 20 MHz
• Integrated non-volatile memory with high endurance specifications for Flash and EEPROM
• On-chip debugging and programming capabilities via SPI interface and debugWIRE system
• Low-power operation supported by picoPower technology and multiple selectable sleep modes

Applications

• Battery-powered wearable devices requiring minimal power consumption
• LED lighting control systems utilizing PWM output
• Sensor nodes in embedded monitoring applications
• Small form-factor consumer electronics

Procurement Notes

Verify the specific suffix MMUR against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 10-MLF configuration. Confirm RoHS compliance status through current datasheets before finalizing procurement plans.

Selection Notes

Select this component when a compact 8-bit MCU with integrated ADC and low power features is required. Consider the limited 1 KB Flash capacity for complex firmware requirements. Evaluate the 10-pin MLF package constraints against available board space and thermal management needs for the target application environment.

Part Context

This part belongs to the ATtiny series of 8-bit microcontrollers produced by Microchip Technology, formerly Atmel. The ATtiny family is designed for cost-sensitive and space-constrained embedded applications. The ATTINY13A variant specifically targets simple control tasks with efficient code execution and minimal peripheral count.

Replacement Considerations

Direct substitutes within the same package may include other ATTINY13A variants with different suffixes indicating distinct packaging or temperature ranges. Verify pinout compatibility and electrical specifications before replacing.
