Overview
The ATTINY26L-8SC is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 2K bytes of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of internal SRAM. The device operates at a maximum clock frequency of 8 MHz with a supply voltage range of 2.7V to 5.5V. It includes a 10-bit ADC with 11 single-ended channels and 8 differential channels, two 8-bit Timer/Counters, and a Universal Serial Interface. The component provides up to 16 programmable I/O lines and supports industrial operating temperatures from -40°C to +85°C.
Feature Summary
- High-performance 8-bit AVR architecture with most instructions executing in a single clock cycle for efficient power consumption versus processing speed optimization.
- Integrated high-precision analog-to-digital converter featuring 11 single-ended channels and 8 differential channels with programmable gain stages.
- Multiple low-power sleep modes including Idle, Noise Reduction, Power-down, and Standby to minimize energy usage in battery-operated applications.
- On-chip non-volatile memory with programming lock capabilities for Flash program and EEPROM data security.
Applications
- Battery chargers
- Lighting ballasts
- Low-end thermostats
- Fire detectors
Procurement Notes
Verify that the specific suffix 'SC' corresponds to the intended package type and temperature grade as defined in the official ordering information table. Confirm that the device revision matches the required errata workarounds, particularly regarding Analog Comparator initialization delays. Ensure compatibility with the specified 2.7V to 5.5V supply voltage range for the target application environment.
Selection Notes
Select this component when a cost-effective solution with integrated analog peripherals is required. The ATtiny26L variant is suitable for applications needing operation down to 2.7V, unlike the standard ATtiny26 which requires 4.5V minimum. Consider the 8 MHz speed grade if lower power consumption is prioritized over higher throughput speeds available in other variants.
Part Context
The ATTINY26L-8SC belongs to the ATtiny26(L) family of 8-bit microcontrollers utilizing the AVR core. This family combines high-density non-volatile memory with an enhanced RISC CPU on a monolithic chip. The series is designed to provide flexible embedded control solutions, supporting various development tools such as macro assemblers, debuggers, and in-circuit emulators.

FAQ
What are the available differential ADC channel gain options?
Seven of the differential ADC channels have an optional programmable gain of 1x or 20x.
How does the Idle mode affect system functionality?
In Idle mode, the CPU stops functioning while the Timer/Counters and interrupt system continue to operate.
