ATTINY427-MF

Overview

The ATtiny427-MF is a microcontroller from the tinyAVR® 2 family, featuring an AVR CPU with hardware multiplier running at up to 20 MHz. It includes 16 KB of Flash memory, 1 KB of SRAM, and 256 B of EEPROM in a 24-pin VQFN package. The device supports a supply voltage range of 1.8V to 5.5V and operates within temperature ranges of -40°C to 85°C or -40°C to 125°C.

Feature Summary

• Features a high-performance low-power AVR CPU with single-cycle I/O access and two-level interrupt controller.
• Includes advanced digital peripherals such as Event System, Configurable Custom Logic (CCL), and multiple timers.
• Provides accurate analog features including a 12-bit differential ADC with Programmable Gain Amplifier (PGA).
• Supports flexible clock options and three sleep modes for optimized power management.

Applications

• General-purpose embedded control systems
• Battery-powered devices requiring low power consumption
• Industrial automation and sensor interfaces
• Consumer electronics with extended temperature requirements

Procurement Notes

Verify the specific ordering suffix 'MF' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pin count and memory size before procurement.

Selection Notes

Select this component for applications requiring vertical migration within the tinyAVR® 2 family without code modification. Consider the 24-pin VQFN package for higher I/O density compared to smaller variants.

Part Context

Part of the tinyAVR® 2 family, offering horizontal and vertical migration paths. Compatible with other devices in the series for scalable design implementations across different pin counts and memory sizes.
