ATTINY20-MMH

Overview

The ATTINY20-MMH is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 2K bytes of in-system programmable Flash, 128 bytes of internal SRAM, and twelve general-purpose I/O lines. The device operates at speeds up to 12 MIPS at 12MHz with a supply voltage range of 1.8V to 5.5V. It includes an 8-bit timer/counter, a 16-bit timer/counter, an eight-channel 10-bit ADC, and serial interfaces including SPI and TWI.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency
• Integrated non-volatile memory allowing in-system programming with extended data retention capabilities
• Comprehensive peripheral set including dual PWM timers, analog comparator, and multi-channel ADC
• Multiple software-selectable power-saving modes to optimize consumption versus processing speed

Applications

• Battery-powered embedded control systems requiring low active current
• Industrial monitoring applications utilizing the industrial temperature range
• Consumer devices needing compact VQFN packaging and multiple I/O lines
• Sensor interface circuits leveraging the integrated 10-bit ADC channels

Procurement Notes

Verify the specific ordering code suffix against official Microchip documentation to confirm package type and lead finish. Confirm that the MMH designation corresponds to the 20-pad VQFN package variant. Check for any product change notifications or lifecycle status updates prior to finalizing procurement plans.

Selection Notes

Select this component when a compact 8-bit AVR solution with moderate Flash capacity is required. Ensure the design accommodates the 1.8V to 5.5V operating range and utilizes the available 12 programmable I/O lines. Consider the VQFN package dimensions for PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the ATtiny20 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares core architectural features with other variants in the series but differs in package configuration and pin count. The MMH suffix specifically identifies the Very Thin Quad Flat No Lead (VQFN) package option within the product lineup.

Replacement Considerations

Direct substitutes include ATTINY20-MMHR for tape-and-reel packaging. Other package variants such as ATTINY20-SSU or ATTINY20-CCU offer functional equivalence with different physical footprints. Verify pin compatibility and firmware compatibility before substituting.
