Chapter 5: LPC43xx Boot ROM

If no header is present, it is assumed that the image is located on address 0x8000 0000
and is executed from there.

5.3.4.4.1

Supported QSPI devices

Multiple QSPI devices from various vendors can be used with the SPIFI interface and the
SPIFI API available LPCWare.com.

The devices listed in

Table 25

have been tested to work as boot devices for the LPC43xx

and with the SPIFI API.

Remark:

All QSPI devices have been tested at an operating voltage of 3.3 V.

This memory requires boot ROM version 11.2 or
higher for booting

Macronix

MX25L25635FMI-10G

A reset delay is needed on the LPC43xx to allow this
memory time to come up before booting.
