ATTINY1624-SSFR

Overview

The ATTINY1624-SSFR is an 8-bit microcontroller from the tinyAVR® 2 family, utilizing the AVR CPU with a hardware multiplier. It features 16 KB of Flash memory, 2 KB of SRAM, and 256 B of EEPROM. The device operates at a maximum clock frequency of 20 MHz within a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit differential ADC with a Programmable Gain Amplifier (PGA), supporting up to 9 input channels. The component is housed in a 14-pin SOIC package and supports industrial temperature ranges.

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 advanced analog peripherals such as a 12-bit differential ADC with PGA and multiple internal voltage references for accurate signal processing.
• Supports CPU-independent inter-peripheral signaling through an Event System and configurable custom logic using programmable Look-Up Tables.
• Provides versatile communication interfaces including dual USARTs, SPI, and TWI, alongside a Real-Time Counter and multiple timer/counters.

Applications

• Real-time control systems requiring efficient processing and low power consumption
• Sensor nodes utilizing the integrated analog features for data acquisition
• Industrial applications needing robust peripheral connectivity and extended temperature operation

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature rating. Ensure the procurement matches the required tape and reel specifications if applicable. Cross-reference the manufacturer part number with official datasheets to validate authenticity and revision levels before integration into production schedules.

Selection Notes

Select this component when a balance of moderate memory capacity and advanced analog capabilities is required in a compact 14-pin form factor. It is suitable for designs migrating from smaller pin-count devices that need expanded I/O or enhanced ADC performance without increasing board space.

Part Context

This device belongs to the tinyAVR® 2 family, which offers vertical migration compatibility with other members of the series. It shares architectural similarities with the ATtiny1626 and ATtiny1627 but provides a reduced pin count and corresponding peripheral set optimized for cost-sensitive and space-constrained embedded applications.

Replacement Considerations

The ATtiny1624-SSFR is functionally compatible with other variants in the tinyAVR® 2 family, such as the ATtiny1626 and ATtiny1627, provided pin counts and peripheral requirements align. Direct substitutes within the same package and speed grade should be verified against the official cross-reference documentation.
