Overview
Parallel Fast Flash Programming
Device Configuration
The Fast Flash Programming Interface provides solutions for high-volume programming using a
standard gang programmer. The parallel interface is fully handshaked and the device is consid-
ered to be a standard EEPROM. Additionally, the parallel protocol offers an optimized access to
all the embedded Flash functionalities.
Although the Fast Flash Programming Mode is a dedicated mode for high volume programming,
this mode is not designed for in-situ programming.
In Fast Flash Programming Mode, the device is in a specific test mode. Only a certain set of pins
is significant. Other pins must be left unconnected.
