ATTINY26L-8MU

Overview

The ATTINY26L-8MU is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features a 32 x 8 register set and executes most instructions in a single clock cycle. The device includes 2K bytes of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at speeds up to 8 MHz with a supply voltage range of 2.7V to 5.5V. Key peripherals include two 8-bit Timer/Counters, a 10-bit ADC with 11 single-ended channels, an analog comparator, and a Universal Serial Interface (USI). It is housed in a 32-lead QFN/MLF package.

Feature Summary

• High-performance 8-bit AVR core with RISC architecture achieving up to 1 MIPS throughput per MHz
• Integrated non-volatile memory including 2K Flash, 128B EEPROM, and 128B SRAM
• Advanced analog subsystem with 10-bit ADC featuring differential inputs and programmable gain
• Multiple power-saving modes including Idle, Noise Reduction, and Power-down

Applications

• Battery chargers
• Lighting ballasts
• Low-end thermostats
• Fire detectors

Procurement Notes

Verify the specific ordering code ATTINY26L-8MU against official Microchip documentation to confirm the 8 MHz speed grade and industrial temperature range. Ensure the 32-lead QFN/MLF package type matches the design requirements. Confirm RoHS compliance status through the manufacturer's current datasheet revision history.

Selection Notes

Select this component for applications requiring low power consumption and high processing efficiency within a compact footprint. The ATtiny26L variant supports operation down to 2.7V, suitable for battery-powered systems. Consider the 32-lead QFN package for space-constrained designs compared to the 20-lead PDIP or SOIC options available in the same family.

Part Context

This device belongs to the ATtiny26(L) family of 8-bit microcontrollers. It shares architectural similarities with the standard ATtiny26 but offers extended low-voltage operation capabilities. The 'L' suffix denotes the low-voltage version supporting 2.7V to 5.5V operation, while the '-8' indicates the maximum clock frequency of 8 MHz. The 'MU' suffix identifies the 32-lead QFN/MLF package.
