#85223 - size... Responding to: ???'s previous message |
Size depends on number of pins to a degree. And if you're thinking of really tiny devices (some 1cm^3) it gets essential.
Think Max233 - advertised as "save space on your PCB". In fact a double-sided MAX232 (16 pin) board with the external capacitors will take less room than the MAX233 chip (22 pin) alone. Giving up the PCB at all and building a "spider" device (just solder the parts' pins together) may make the device even smaller. The ACE series microcontrollers from Fairchild fascinated me. Not '51, but only 8 pins from which 6 are IO. Tiny amount of RAM/FLASH but a lot of features. And being SMT, they are really tiny. |
