ATTINY26L-8SU

The ATTINY26L-8SU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It is based on RISC architecture with 118 powerful instructions, most executed in a single clock cycle, and includes 32 x 8 general-purpose working registers. The device offers 2KB of in-system programmable Flash memory with 10,000 write/erase cycles, 128 bytes of EEPROM with 100,000 write/erase cycles, and 128 bytes of internal SRAM.

Key electrical characteristics include a supply voltage range of 2.7V to 5.5V, maximum clock frequency of 8 MHz, and an operating temperature range of -40°C to 85°C. Power consumption is optimized for low-power applications: typical active mode draws 15 mA at 16 MHz/5V, 0.70 mA at 1 MHz/3V, and idle mode 0.18 mA at 1 MHz/3V, with power-down current less than 1 µA.

Peripheral features include an 8-bit timer/counter with separate prescaler, an 8-bit high-speed timer with PWM outputs, a Universal Serial Interface (USI) with start condition detector, a 10-bit ADC with 11 single-ended channels or 8 differential channels (7 with programmable gain), an on-chip analog comparator, brown-out detection, Power-On Reset (POR), and a programmable Watchdog Timer (WDT). The device provides 16 programmable I/O lines.

The ATTINY26L-8SU is supplied in a 20-lead SOIC (0.295", 7.50mm Width) surface-mount package, typically packaged in tubes. It is suitable for a wide range of embedded control applications including sensor interfacing, battery-powered systems, industrial automation, and consumer electronics.
