The ATtiny48/88 are 8-bit AVR microcontrollers from Microchip, designed for cost-effective, compact projects. The ATtiny48 has 4KB flash, while the ATtiny88 offers 8KB, both with 256B SRAM and 64B EEPROM. Featuring 28 I/O pins, 8 ADC channels, and operating at 1.8-5.5V, they run up to 12MHz. Ideal for sensors, LED displays, or small automation, they’re programmable via ISP or Arduino IDE.
