20. Fast Flash Programming Interface (FFPI)
20.1
Overview
The Fast Flash Programming Interface provides two solutions - parallel or serial - for high-volume 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 func-
tionalities. The serial interface 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.
