The timing values are related to the specification of the flash device itself, not the DLPC3470 controller .

(2)

The DLPC3470 controller does not drive the HOLD or WP (active low write protect) pins on the flash device, and thus these pins should

be tied to a logic high on the PCB through an external pullup.

The specific and timing compatibility requirements for a DLPC3470 controller compatible flash are listed in

Table 6 and Table 7.

(1)

The flash supply voltage must match VCC_FLSH on the DLPC3470 controller . Special attention needs to be paid when ordering

devices to be sure the desired supply voltage is attained as multiple voltage options are often available under the same base part

number.

(2)

Beware when considering Numonyx (Micron) serial flash devices as they typically do not have the 4KB sector size needed to be

DLPC3470 controller compatible.

(3)

All of these flash devices appear compatible with the DLPC3470 controller , but only those marked with yes in the DVT column have

been validated on the EVM reference design. Those marked with no can be used at the ODM’s own risk.

The DLPC3470 controller supports 1.8-, 2.5-, or 3.3-V serial flash devices. To do so, VCC_FLSH must be

supplied with the corresponding voltage. Table 7 contains a list of 1.8-, 2.5-, and 3.3-V compatible SPI serial

flash devices supported by DLPC3470 controller .
