The ATTINY45-20PU is an 8-bit AVR microcontroller from Microchip Technology, built on advanced RISC architecture. It features 4KB of in-system programmable Flash memory, 256 bytes of SRAM, and 256 bytes of EEPROM, with endurance ratings of 10,000 and 100,000 write/erase cycles respectively. The device operates over a supply voltage range of 2.7V to 5.5V and can run at clock frequencies up to 20MHz at 4.5-5.5V or 10MHz at 2.7-5.5V.
Key peripherals include a 10-bit ADC with 4 single-ended channels, two 8-bit timer/counters with PWM outputs, a Universal Serial Interface (USI) supporting SPI, I2C, and UART, and a programmable watchdog timer with separate on-chip oscillator. The microcontroller also includes brown-out detection, power-on reset, and low-power operating modes such as idle, ADC noise reduction, and power-down.
The ATTINY45-20PU is housed in an 8-pin PDIP package for through-hole mounting, with 6 programmable I/O lines. With an industrial temperature range of -40°C to +85°C, it is suitable for embedded control applications such as sensor interfacing, industrial automation, and low-power electronic systems.
The ATTINY45-20PU operates from 2.7V to 5.5V, with a maximum clock speed of 20MHz at 4.5V to 5.5V and 10MHz at 2.7V to 5.5V.
The ATTINY45-20PU comes in an 8-pin PDIP (8-DIP) package with through-hole mounting and a 2.54mm lead pitch.
The device operates over an industrial temperature range of -40°C to +85°C.
Yes, the manufacturer page lists the ATTINY45-20PU as RoHS compliant.
The maximum clock frequency is 20MHz at a supply voltage of 4.5V to 5.5V; at lower voltages it is 10MHz.
The ATTINY45-20PU provides 6 programmable I/O lines.
It includes 4KB Flash program memory, 256B SRAM, and 256B EEPROM.
