Overview
The ATtiny3224-XF is an 8-bit microcontroller from the tinyAVR® 2 family, featuring a high-performance AVR CPU with hardware multiplier running at up to 20 MHz. It includes 32 KB of in-system self-programmable Flash memory, 3 KB of SRAM, and 256B of EEPROM. The device supports a supply voltage range of 1.8V to 5.5V and offers up to 12 general-purpose I/O pins in a 14-pin TSSOP package.
Feature Summary
- Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
- Includes advanced digital peripherals such as Configurable Custom Logic (CCL) with four programmable Look-Up Tables.
- Provides accurate analog features including a 12-bit differential ADC with Programmable Gain Amplifier (PGA).
- Supports single-pin Unified Program and Debug Interface (UPDI) activated by shared pin using high-voltage signal or fuse override.
Applications
- General purpose embedded control applications
- Intelligent sensing systems
- User interface implementations
- Motor control applications
Procurement Notes
Verify that the ordering suffix 'XF' corresponds specifically to the TSSOP package type and the -40°C to +125°C extended temperature range as defined in the official datasheet naming conventions. Confirm that the specific variant matches the required industrial or extended temperature specifications before finalizing procurement orders.
Selection Notes
Select this component when vertical migration within the tinyAVR® 2 family is required without code modification. Ensure the design utilizes the full 32 KB Flash capacity and benefits from the 20 MHz maximum frequency operation. Verify that the 14-pin form factor accommodates the necessary 12 general-purpose I/O pins and peripheral requirements.
Part Context
This device belongs to the tinyAVR® 2 family, which provides horizontal and vertical migration paths. The ATtiny3224 serves as the 14-pin variant within the 32 KB Flash segment, sharing pin and feature compatibility with larger packages like the ATtiny3226 and ATtiny3227 while offering reduced pin counts compared to its siblings.

FAQ
What is the function of the User Row in nonvolatile memory?
The 32B User Row can keep data during chip-erase operations and be programmed while the device is locked.
How does the Event System benefit peripheral signaling?
It enables CPU-independent and predictable inter-peripheral signaling, reducing processor overhead.
