ATTINY1624-XFR

Overview

The ATtiny1624-XFR is an 8-bit microcontroller from the tinyAVR® 2 family, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 16 KB of self-programmable Flash memory, 2 KB of SRAM, and 256 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports up to 12 general-purpose I/O pins. Key peripherals include a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, and a Real-Time Counter.

Feature Summary

• Features a high-performance low-power AVR CPU running at up to 20 MHz with single-cycle I/O access and a two-cycle hardware multiplier.
• Includes a 12-bit differential Analog-to-Digital Converter (ADC) with Programmable Gain Amplifier (PGA) and up to 15 input channels.
• Supports flexible communication via two USARTs with auto-baud, Master/Slave SPI, and Master/Slave TWI interfaces.
• Integrates an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL) with four Look-Up Tables.

Applications

• Low-power portable consumer electronics
• Industrial sensor nodes and monitoring systems
• Battery-operated instrumentation

Procurement Notes

Verify that the ordering suffix 'XFR' corresponds to the TSSOP package and Tape & Reel carrier type as specified in the manufacturer's catalog. Confirm the temperature grade matches the design requirements, as standard variants typically cover -40°C to +85°C. Ensure compatibility with the UPDI programming interface during procurement planning.

Selection Notes

Select this component for designs requiring vertical migration within the tinyAVR® 2 family without code modification. Consider the 14-pin SOIC or TSSOP packages if pin count constraints are present. Evaluate the 12-bit ADC performance against application signal requirements and verify that the 16 KB Flash capacity meets firmware storage needs.

Part Context

This part belongs to the tinyAVR® 2 family, which shares architectural features across 14-, 20-, and 24-pin variants. The ATtiny1624 specifically offers 16 KB of Flash in a compact footprint. It is designed for applications needing efficient code execution and advanced analog capabilities in a small form factor.

Replacement Considerations

Devices such as ATtiny1626 and ATtiny1627 offer increased I/O counts while maintaining feature compatibility. For lower pin count requirements, the ATtiny824 provides similar functionality with reduced memory size. Verify package availability when substituting, as options vary by pin count.
