ATTINY212-SSN

Overview

The ATTINY212-SSN is an 8-bit AVR microcontroller from the tinyAVR 1-series, housed in a SOIC-8 package. It features 2 KB of self-programmable Flash memory, 128 bytes of SRAM, and 64 bytes of EEPROM. The device operates at clock frequencies up to 20 MHz with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 16-bit Timer/Counter Type A (TCA), a 16-bit Timer/Counter Type B (TCB), a USART, SPI, TWI, a 10-bit ADC, and a DAC.

Feature Summary

• Integrates Core Independent Peripherals (CIPs) such as TCA, TCB, and TCD for CPU offloading.
• Supports single-pin unified programming and debugging via UPDI interface.
• Includes an Event System for predictable inter-peripheral signaling without CPU intervention.
• Features configurable custom logic using programmable look-up tables.

Applications

• Low-power embedded control systems
• Sensor data acquisition interfaces
• Simple serial communication nodes
• Basic timing and counting applications

Procurement Notes

Verify the specific suffix 'SSN' corresponds to the SOIC-8 package and industrial temperature range (-40°C to +105°C). Confirm RoHS compliance status through official Microchip documentation. Ensure design compatibility with the UPDI programming interface requirements before procurement.

Selection Notes

Select this component when a compact 8-pin footprint is required alongside standard AVR architecture benefits. Consider the 2 KB Flash limit for code size constraints. Evaluate the peripheral set against application needs, noting the absence of certain high-speed interfaces found in larger packages within the same series.

Part Context

This part belongs to the tinyAVR 1-series family, which introduces advanced features like the Event System and Core Independent Peripherals compared to previous generations. It shares architectural similarities with the ATtiny214 and ATtiny412 but differs in memory capacity and pin count.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other members of the tinyAVR 1-series family, such as the ATtiny214 or ATtiny412, provided memory requirements are met. Verify electrical specifications and firmware compatibility for any cross-model substitution.
