Dear All:

I connect a 1Mbit flash SST39VF010-70 on CY7C68013A-128AXC address/data bus,and setting EA=1,but it doesn't work.

I sure I program correct file format(binary).

If I connect and boot from I2C EEPROM,setting EA=0,it will be OK.

Does CY7C68013A-128AXC support SST39VF010-70?

How to solve this problem?

I connect SST39VF010-70 pin assignments as shown below:

WE# to 3.3V

OE# to CY7C68013A-128AXC PSEN#

CE# to GND

A16 to 3.3V

A15~A0 to CY7C68013A-128AXC address bus

D7~D0 to CY7C68013A-128AXC data bus

VDD to 3.3V


NC no connection

Not sure if you have had a look at the app note which talks about modification that has to be done to make it work in a parallel boot mode:

Also the device is a 70ns operating Flash. If the speed of operation is 48Mhz, it may not be fast enough.
