ATTINY25-20SSU Description

Short technical summary and product information.

The ATTINY25-20SSU is an 8-bit AVR microcontroller from Microchip Technology based on the AVR core. It features 2KB of in-system programmable Flash memory, 128B of SRAM, and 128B of EEPROM. The device operates at a maximum clock frequency of 20MHz at 4.5-5.5V supply, and 10MHz at 2.7-5.5V. It includes a 10-bit ADC with 4 single-ended channels, a USI for serial communication, and peripherals such as brown-out detection, power-on reset, PWM, and watchdog timer.

 

The microcontroller is designed for low-power applications, with active mode current of 300 µA at 1MHz/1.8V and power-down mode current of 0.1 µA at 1.8V. It has six programmable I/O lines and an internal calibrated oscillator. The operating temperature range is -40°C to 85°C, making it suitable for industrial environments.

 

The device is supplied in an 8-pin SOIC surface mount package (8-SOIC) with a width of 3.90mm. It is RoHS compliant (unverified) and has an MSL of 1. The ATTINY25-20SSU is ideal for embedded control applications requiring small footprint and low power consumption.
