7.2. Circuit Diagram Example

S5PV210 has an external OneNAND control ports.
Xm0ADDR[15:0]
Xm0DATA[15:0]
ONANDXL_CSn[1]
S5PC110
ONDXL_AVD
ONDXL_RPn
ONDXL_SMCLK
Note) In case of internal OneNand(POP), ONANDXL_CSn[0] and ONDXL_INT[0] signals are used for internal
OneNand. If you want to use a external OneNand additionally, Only ONANDXL_CSn[1] and ONDXL_INT[1]
should be used for it
Caution
• The INT pin of each OneNAND device must be pulled up by an 4.7KOhm external pull-up resistor.
• If you want to boot by OneNAND, you should use ONANDXL_CSn0, ONDXL_INT 0 .
• OneNand signal power domain belongs to VDD_M0
