Hi! I need your help, guys!
I tried to connect AT32UC3C0512C microcontroller with three parallel eeprom memories AT28C010. I connected microcontroller with memories as follows. All address and data pins of each chip of memory connect in parallel directly to the appropriate outputs of EBI of microcontroller. CE input of the first memory I connected directly to the EBI NCS pin of microcontroller, CE input of the second memory - to the EBI NCS pin and CE input of the third memory - to the EBI NCS pin. OE output pins of each memory chip I connected in parallel to the EBI NRD pin. And last ones, WE input pins, I connected in parallel to the EBI NWE0 pin. Power supply - 5V (microcontroller and memories).
I setup EBI, MDMA and SMC but nothing works. Tomorrow I will write here some code examples, but firstly I want to hear about scheme. Is it correct or maybe somewhere pullups or pulldowns needed? And is it possible to connect this type of memory with this microcontroller?
Thanks a lot!
