It has support for external SRAM, unfortunately it takes a lot of pins so isn't used that often.
- erosenbe0 4y agoI think a lot of legacy 1980s style systems already had an 8 bit external data bus (think z80, 80xx, 68xx), so if you wanted to upgrade with more I/O, uart, seven segment displays and the like, the atmega is a flexible choice that could be tacked onto the bus. That's my understanding.
