ATtiny48 and ATtiny88 are picoPower microcontrollers in the Atmel AVR family. Both are available in either the 28-pin DIP, 28-pin QFN, 32-pin TQFP, 32-pin QFN, or the 32-pin UFBGA package with a 4, 8, or 12 MHz selectable clock speed. Runnning at higher clock speeds require higher minimum operating voltages, with 2.7 volts for 8 MHz and 4.5 volts for 16 MHz.

ATtiny48

The ATtiny48 has 4 KB of flash, 256 B of SRAM, and the following features:

  • 12 touch channels
  • 1 SPI
  • 1 I2C
  • 10-bit ADC with 8 channels
  • 1 analog comparator
  • temperature sensor
  • 2 timers
  • 2 PWM
  • internal RC oscillator
  • watchdog

ATtiny88

The ATtiny88 is identical to the ATtiny48 except that it has 8 KB of flash and 512 B of SRAM.
