ATTINY20-MMHR

Overview

The ATTINY20-MMHR is an 8-bit AVR microcontroller featuring 2K bytes of in-system programmable Flash and 128 bytes of internal SRAM. It operates at speeds up to 12MHz with a supply voltage range of 1.8V to 5.5V. The device includes one 8-bit timer/counter, one 16-bit timer/counter, an 8-channel 10-bit ADC, and master/slave SPI and slave TWI interfaces. It utilizes a 20-pad VQFN package.

Feature Summary

• Advanced RISC architecture achieving up to 12 MIPS throughput at 12MHz
• Integrated 8-channel 10-bit analog-to-digital converter
• Dual timer/counters supporting multiple PWM channels
• Supports master/slave SPI and slave TWI serial communication

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications within the industrial temperature range
• Sensor interface modules utilizing the onboard ADC
• Communication nodes using SPI or TWI protocols

Procurement Notes

Verify the specific ordering suffix 'H' indicates NiPdAu lead finish and 'R' denotes tape and reel packaging. Confirm the component meets RoHS compliance standards. Ensure the selected variant matches the required speed grade for the target operating voltage. Check for any recent product change notices regarding marking or fabrication sites before finalizing procurement orders.

Selection Notes

Select this model when a compact VQFN footprint is required alongside standard AVR peripheral sets. The 12MHz speed grade supports processing needs at higher supply voltages. Consider the 128-byte SRAM limit for complex data handling tasks. Verify that the 12 programmable I/O lines meet the system's pin count requirements without external expansion.

Part Context

This component belongs to the ATtiny family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares core architectural features with other devices in the series, such as the ATtiny20-CCU and ATtiny20-XU, differing primarily in package type and speed grading options available for specific voltage ranges.

Replacement Considerations

Direct substitutes include ATTINY20-CCUR and ATTINY20-XUR. These alternatives offer identical functional specifications but utilize UFBGA or WLCSP packages respectively. Ensure mechanical compatibility with existing PCB footprints when selecting these variants.
