at89s8252 with external ram
I'm looking for a schematic of an Atmel AT89S8282 (or alike). I want to learn more about microcontrollers. Preferrably the following would be nice:
- In system programmable
- DA/AD Converter
- external RAM
- external EEPROM
- LCD
- leds on some ports
- RTC
- 232 interface
- I2C interface
I know that you can buy such boards but I would like to do the layout myself so I learn there also something.
Thx
