ATtiny24A[edit]
The ATtiny24A is the picoPower version of the ATtiny24.
ATtiny44[edit]
The ATtiny44 is identical to the ATtiny24 except that it has 4 KB of flash, 256 B of SRAM, 256 B of EEPROM, and includes 6 touch channels.
ATtiny44A[edit]
The ATtiny44A is the picoPower version of the ATtiny44.
ATtiny84[edit]
The ATtiny84 is identical to the ATtiny24 except that it has 8 KB of flash, 512 B of SRAM, and 256 B of EEPROM.
ATtiny84A[edit]
The ATtiny84A is the picoPower version of the ATtiny84.
