Overview
The ATtiny826-SFR is an 8-bit microcontroller from the Microchip tinyAVR® 2 family, featuring a high-performance AVR CPU with a hardware multiplier operating at up to 20 MHz. It includes 8 KB of in-system self-programmable Flash memory, 1 KB of SRAM, and 128 B of EEPROM. The device provides 18 general-purpose I/O pins and supports a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, and a configurable custom logic (CCL) block.
Feature Summary
- Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
- Includes a 12-bit differential Analog-to-Digital Converter (ADC) with Programmable Gain Amplifier (PGA) and up to 15 input channels.
- Supports single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.
- Offers three sleep modes: Idle, Standby, and Power-Down for optimized power consumption.
Applications
- Industrial control systems requiring robust peripheral interfaces
- Battery-powered devices utilizing low-power sleep modes
- Sensor interface applications leveraging the high-resolution ADC
Procurement Notes
Verify the specific suffix 'SFR' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pin count and memory size before procurement.
Selection Notes
Select this component for designs needing vertical migration within the tinyAVR 2 family without code modification. Consider the 20-pin package options if additional I/O or specific form factors are required compared to smaller variants.
Part Context
This part belongs to the tinyAVR® 2 family, which shares architectural similarities with other members like the ATtiny426 and ATtiny827. These devices offer horizontal and vertical migration capabilities, allowing designers to scale features while maintaining software compatibility across the series.
Replacement Considerations
Direct substitutes within the same family include ATtiny426 and ATtiny827, provided pinout and memory requirements align. Verify that alternative packages meet the thermal and physical constraints of the original design.
