3. TECHNICAL BRIEF
Calypso-Plus has NAND Flash interface and it allows NAND EEPROM as a mass external
storage facility.
The interface implements a 8-bit parallel data bus in addition to the control signals for selecting
chip, writing/Reading, command and address latching, ready/busy status.
So, F1200 uses this interface as for NAND Flash memory and uses stacked memory (SRAM +
NOR-Flash + NAND-Flash) as shown in (Figure 8.)
