ATTINY3216-SN

Overview

The ATtiny3216-SN is an 8-bit microcontroller from the tinyAVR 1-series, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 32 KB Flash, 2 KB SRAM, and 256 bytes EEPROM. The device operates between 1.8 V and 5.5 V, supports up to 22 I/O lines, and integrates peripherals such as TCA, TCB, TCD timers, USART, SPI, TWI, ADCs, DACs, and PTC. It utilizes a single-pin UPDI interface for programming and debugging.

Feature Summary

• Integrates Core Independent Peripherals (CIPs) and Event System for CPU-independent operation
• Supports capacitive touch interfaces via Peripheral Touch Controller (PTC)
• Features Configurable Custom Logic (CCL) with programmable look-up tables
• Includes automated CRC memory scan for data integrity verification

Applications

• Low-power embedded control systems
• Capacitive touch user interfaces
• Industrial monitoring and sensor nodes
• Battery-operated portable devices

Procurement Notes

Verify the specific speed grade and temperature range required for your application against the official datasheet specifications. Confirm package availability and ensure compliance with RoHS directives. Check for any automotive qualification requirements if applicable, as separate documentation may exist for those variants.

Selection Notes

Select this component for designs requiring high peripheral density in a compact 20-pin SOIC package. Consider the integrated PTC for touch applications and the flexible clock options for power management. Ensure the chosen speed grade aligns with the supply voltage constraints defined in the electrical characteristics section of the datasheet.

Part Context

This part belongs to the ATtiny3216/3217 family within the tinyAVR 1-series. It shares architectural similarities with other members like the ATtiny1616 but offers increased Flash memory capacity. The series emphasizes low power consumption and advanced analog features suitable for modern embedded applications.

Replacement Considerations

Direct substitutes include other parts within the ATtiny3216/3217 family with compatible pinouts and memory sizes. Verify functional equivalence regarding peripheral configurations and electrical specifications before substitution.
