ATtiny87 and ATtiny167 are microcontrollers in the Atmel AVR family. Both are available in either the 20-pin SOIC, the 20-pin TSSOP, or the 32-pin VQFN package with a 4, 8, or 16 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.

ATtiny87

The ATtiny87 has 8 KB of flash, 512 B of SRAM, 512 B of EEPROM and the following features:

  • 2 SPI
  • 1 I2C
  • 1 UART
  • 1 LIN
  • 10-bit ADC with 11 channels
  • 1 analog comparator
  • temperature sensor
  • 2 timers
  • 9 PWM channels
  • 32 kHz RTC
  • internal RC oscillator
  • watchdog

ATtiny167

The ATtiny167 is identical to the ATtiny87 except that it has 16 KB of flash.
