AT minimum you need a SX chip (you can use internal clock generator if you don't need a very good accuracy). You can buy the tool kit at following link: [url=http://www.parallax.com/Store/Microcontrollers/SXProgrammingKits/tabid/140/List/0/CategoryID/17/Level/a/SortField/0/Default.aspx]SX Tech Tool Kit LITE[/url] Then the program you write by assembly or SX-B (basic) is stored in to the internal flash memory. For your data there is of corse a RAM. If you need to store some datas also without power supply, You have to use a EEPROM or similar devices.
