ATTINY204-SSNR

Overview

The ATtiny204-SSNR is an 8-bit AVR microcontroller featuring a 2 KB Flash program memory, 128 bytes of SRAM, and 64 bytes of EEPROM. It operates at a maximum clock frequency of 20 MHz within a supply voltage range of 1.8 V to 5.5 V. The device includes a 10-bit ADC with 115 ksps sampling rate, six analog channels, and twelve programmable I/O lines. It supports I2C, SPI, and USART interfaces via a single-pin UPDI for programming and debugging.

Feature Summary

• Integrates Core Independent Peripherals (CIP) such as the Event System and SleepWalking to enable low-power operation while maintaining peripheral functionality during CPU sleep modes.
• Features a high-performance AVR RISC architecture capable of executing instructions in a single cycle with a two-cycle hardware multiplier.
• Includes Configurable Custom Logic (CCL) utilizing programmable look-up tables for implementing complex logic functions without CPU intervention.

Applications

• Battery-powered sensor nodes requiring extended standby life through picoPower technology
• Industrial control systems utilizing configurable custom logic for signal processing
• Smart home devices employing low-voltage operation and integrated analog-to-digital conversion

Procurement Notes

Verify that the ordering suffix 'SSNR' corresponds to the tape-and-reel packaging format rather than tube packaging. Confirm the specific temperature grade matches the application requirements, as industrial grades are available. Ensure compatibility with the single-pin Unified Program and Debug Interface (UPDI) tools for firmware development and production programming.

Selection Notes

Select this component when a balance of moderate code capacity and extensive analog peripherals is required. The ATtiny204 offers sufficient memory for complex logic while providing multiple timer/counters and communication interfaces. Consider the availability of the 32.768 kHz ultra-low-power oscillator for precise timekeeping applications without external components.

Part Context

This device belongs to the tinyAVR 0-Series family, which emphasizes energy efficiency and peripheral independence. It shares architectural similarities with other members like the ATtiny404 but differs in memory size. The series utilizes advanced manufacturing processes to achieve low power consumption across various operating speeds and voltage levels.

FAQ

What is the function of the single-pin interface on the ATtiny204?

The device uses a Single Pin Unified Program and Debug Interface (UPDI) for both in-system programming and debugging, eliminating the need for separate reset, clock, and data pins used in older architectures.

How does the Event System benefit the ATtiny204's performance?

The Event System allows peripherals to communicate directly with each other without CPU intervention, reducing power consumption and freeing up the processor for other tasks or allowing it to enter deeper sleep states.

What analog features are included in this microcontroller?

It includes a 10-bit Analog-to-Digital Converter (ADC) with up to six selectable channels, an Analog Comparator, and five selectable internal voltage references (0.55V, 1.1V, 1.5V, 2.5V, and 4.3V).
