Overview
The ATtiny3226-XF is a member of the tinyAVR® 2 family, featuring an 8-bit AVR CPU with hardware multiplier running at up to 20 MHz. It provides 32 KB Flash, 3 KB SRAM, and 256B EEPROM in a 20-pin package. The device includes a 12-bit differential ADC with PGA, Event System, CCL, USART, SPI, TWI, TCA, TCB, and RTC peripherals.
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 requiring vertical migration compatibility.
- Applications needing precise analog signal processing with differential ADC inputs.
- Systems utilizing event-driven architectures for predictable inter-peripheral signaling.
Procurement Notes
Verify the specific ordering suffix 'XF' against Microchip's official catalog to confirm package type and temperature range. Ensure the selected variant matches your design's voltage and frequency requirements. Consult datasheet DS40002345B for detailed electrical characteristics and pinout configurations before finalizing procurement.
Selection Notes
Select this model for designs requiring 32 KB Flash and 20-pin form factor within the tinyAVR 2 family. It offers horizontal migration to smaller pin counts or vertical scaling to larger devices without code modification. Consider the 12-bit ADC and CCL capabilities if complex logic or high-precision analog conversion is required.
Part Context
This component belongs to the tinyAVR® 2 family, which introduces enhanced performance and new peripherals compared to previous generations. The family supports seamless migration between devices with varying pin counts and memory sizes while maintaining software compatibility.
Replacement Considerations
ATtiny3224 and ATtiny3227 are fully pin and feature compatible within the same family. Verify pin count differences (14 vs 24) and ensure peripheral availability matches application needs when substituting.
