is there a similar IC to the Attiny85 with less I/O and maybe cheaper?

A lot of times I only use 2 I/O pins on the ATTINY85 and was wondering if there's a cheaper IC that I can still program the same why with just less I/O pins?

If you only need a few units, you can probably scare up some ATTINY12 controllers. 8 pins, 1K flash, not much EEPROM. No ram only the 32x8 register set and hardware 2 level interrupt. Very low power dissipation, internal or external/ crystal clock.

Long before Atmel was even a company I needed a controller with one input pin and one output pin.
At that time I used a Microchip PIC12C508 which used UV-EPROM. These have been replaced with flash memory PIC12F508 and newer PIC16F15313.
