ATTINY24-20SSUR

Overview

The ATTINY24-20SSUR is an 8-bit AVR microcontroller featuring 2KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 10-bit ADC, two PWM channels, and multiple communication interfaces including SPI and USART.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Non-volatile memory segments with high endurance for flash and EEPROM
• Integrated analog-to-digital converter with programmable gain options
• Low power consumption modes including idle, standby, and power-down

Applications

• Battery-powered embedded systems requiring low power operation
• Industrial control applications utilizing the wide operating temperature range
• Sensor interface circuits leveraging the on-chip ADC and analog comparator
• Communication nodes using SPI or USART peripheral interfaces

Procurement Notes

Verify the specific suffix 'SSUR' corresponds to the 14-SOIC package variant when sourcing. Confirm that the '20' speed grade matches the required 20 MHz operational frequency for the target application voltage. Ensure compatibility with existing PCB footprints for the SOIC-14 package form factor during procurement planning.

Selection Notes

Select this component for designs requiring a balance of processing speed and power efficiency within the AVR family. Consider the 20 MHz speed grade against lower frequency variants if power savings are critical. Evaluate the available I/O lines and peripheral set against system requirements before choosing between similar ATtiny models.

Part Context

This part belongs to the ATtiny24/44/84 series of 8-bit AVR microcontrollers manufactured by Atmel (now Microchip Technology). These devices share a common core architecture but differ in memory sizes and pin counts. The ATTINY24 represents the entry-level configuration within this specific family grouping.

Replacement Considerations

Direct replacements include other speed grades within the ATTINY24 series such as ATTINY24-10SSUR. Cross-series migration may require schematic changes due to differing pin configurations in larger packages like the ATTINY44.
