ATTINY3224-XFR

Overview

The ATtiny3224-XFR is a member of the tinyAVR® 2 family, featuring an 8-bit AVR CPU with hardware multiplier. It provides 32 KB Flash, 3 KB SRAM, and 256B EEPROM. The device operates at up to 20 MHz and supports a supply voltage range of 1.8V to 5.5V. It includes a 12-bit differential ADC with PGA, Event System, CCL, USART, SPI, TWI, and UPDI.

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 applications
• Battery-powered devices requiring low power consumption
• Industrial monitoring and sensing systems

Procurement Notes

Verify the specific package type associated with the XFR suffix, which indicates TSSOP or SSOP packaging in Tape & Reel format. Confirm the temperature grade matches your application requirements, as standard variants typically cover -40°C to +85°C. Ensure compatibility with existing design footprints if migrating from other pin counts within the same family.

Selection Notes

Select this model for designs requiring 32 KB of program memory and up to 22 GPIOs in a compact surface-mount package. Consider the XFR suffix for automated assembly needs due to its tape and reel packaging. Evaluate the need for the 12-bit ADC and CCL features against simpler, lower-memory alternatives like the ATtiny1624 if cost reduction is critical.

Part Context

This component belongs to the tinyAVR® 2 family, designed for vertical migration without code modification. It shares architectural similarities with other members like the ATtiny3226 and ATtiny3227, differing primarily in pin count and peripheral availability. The family emphasizes flexibility through its event system and configurable logic.

Replacement Considerations

Direct pin-compatible replacements within the same family include ATtiny3226 and ATtiny3227, offering higher pin counts. For downward migration, consider ATtiny1624/1626/1627 or ATtiny824/826/827, though these have reduced memory and peripheral resources.

FAQ

What does the 'XFR' suffix indicate?

The 'XFR' suffix denotes that the device is packaged in TSSOP or SSOP form factor and supplied in Tape & Reel format for automated pick-and-place assembly.

Does this device support automotive applications?

Standard ATtiny3224 parts are not automotive qualified. Automotive-qualified versions are available as VAO variants, which meet AEC-Q100 requirements.
