ATTINY13A-MMU

Overview

The ATTINY13A-MMU is an 8-bit AVR microcontroller featuring a 10-pad VDFN package. It includes 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 an operating voltage range of 1.8V to 5.5V. Key peripherals consist of a 4-channel 10-bit ADC, an 8-bit Timer/Counter with two PWM channels, an analog comparator, and a programmable watchdog timer. It offers six programmable I/O lines and supports debugWIRE on-chip debugging.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput.
• Integrated non-volatile memory segments including self-programmable Flash and EEPROM.
• On-chip debug system (debugWIRE) and SPI-based in-system programming capabilities.
• Multiple low-power sleep modes including Idle, ADC Noise Reduction, and Power-down.

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications within the industrial temperature range
• Simple sensor interfaces utilizing the integrated ADC

Procurement Notes

Verify the specific suffix MMU corresponds to the 10-pad VDFN package configuration. Confirm the required speed grade matches the target operating voltage, as performance varies between 4 MHz, 10 MHz, and 20 MHz based on supply levels. Ensure the industrial temperature rating aligns with environmental specifications.

Selection Notes

Select this component when a compact 10-pin form factor is necessary alongside standard ATtiny13A functionality. Consider the trade-off between the higher pin count of the VDFN package versus smaller 8-pin alternatives if fewer I/O lines suffice. Verify that the 6 available I/O pins meet the interface requirements for the target application.

Part Context

This part belongs to the Microchip ATtiny13A series, which utilizes the AVR enhanced RISC architecture. The MMU suffix specifically denotes the 10-pad VDFN package variant, distinguishing it from 8-pin SOIC or PDIP options. It shares core architectural features with other members of the tinyAVR family while offering a distinct physical footprint.

Replacement Considerations

Direct replacements include ATTINY13A-SSU (8-SOIC) or ATTINY13A-MU (20-WQFN). These parts share identical electrical characteristics and instruction sets but differ in package dimensions and pin counts. Ensure mechanical compatibility before substitution.
