ATTINY48-AU Description

Short technical summary and product information.

The ATTINY48-AU is an 8-bit AVR microcontroller from Microchip Technology, part of the ATtiny family. It features 4KB of in-system self-programmable Flash memory, 256B of SRAM, and 64B of EEPROM for non-volatile data storage. The device operates at a maximum clock frequency of 12MHz and supports a supply voltage range of 1.8V to 5.5V.

 

This microcontroller includes a rich set of peripherals: one 8-bit timer/counter, one 16-bit timer/counter, a 10-bit ADC with 8 channels, two PWM channels, and a watchdog timer with separate on-chip oscillator. Communication interfaces include I2C, SPI, and I2S. Additional features include brown-out detection, power-on reset, and an internal calibrated oscillator.

 

The ATTINY48-AU is housed in a 32-lead TQFP package (7x7mm) with surface mount termination. It operates over the industrial temperature range of -40°C to 85°C. The device is ideal for embedded control applications requiring low power consumption and a moderate number of I/O pins.
