Overview
Parallel Fast Flash Programming
Device Configuration
The Fast Flash Programming Interface provides two solutions - parallel or serial - for high-vol-
ume programming using a standard gang programmer. The parallel interface is fully
handshaked and the device is considered to be a standard EEPROM. Additionally, the parallel
protocol offers an optimized access to all the embedded Flash functionalities. The serial inter-
face uses the standard IEEE 1149.1 JTAG protocol. It 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.
