ATTINY202-SSN

Overview

The ATtiny202-SSN is an 8-bit AVR microcontroller featuring 2 KB of Flash memory, 128 bytes of SRAM, and 64 bytes of EEPROM. It operates at a maximum clock frequency of 20 MHz within a voltage range of 1.8 V to 5.5 V. The device includes a 10-bit ADC with 115 ksps sampling rate, a 16-bit Timer/Counter Type A (TCA), a 16-bit Timer/Counter Type B (TCB), a Real-Time Counter (RTC), USART, SPI, and TWI interfaces. It utilizes a single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official Microchip documentation. Ensure the source document corresponds to the correct datasheet revision for accurate electrical characteristics. Check for any recent lifecycle notices regarding availability or design-in recommendations.

Selection Notes

Select this component when a compact 8-pin solution is required with integrated analog-to-digital conversion and timer resources. Consider the ATtiny402 variant if additional program memory is necessary. Evaluate the operating voltage requirements against the specified speed grades to ensure stable performance across the intended temperature range.

Part Context

This device belongs to the tinyAVR 0-Series family, designed for cost-sensitive applications. It shares architectural similarities with other members of the series but offers specific memory configurations. The SOIC-8 package provides a surface-mount option suitable for space-constrained designs.

Replacement Considerations

Direct pin-compatible replacements within the same series include the ATtiny402-SSN for increased memory capacity. Cross-series migration may require schematic and firmware adjustments due to peripheral differences.
