Congratulations on purchasing ST's DK4000 Development kit.
The DK4000 (110 or 220 volt version) is a low cost kit for eval-
uating the PSD4000 series of Flash Programmable System
Devices called PSDs. The DK4000 kit is extremely versatile,
and can be used in several different modes. It can be used to
demonstrate the PSD4000's capability of JTAG In-System Pro-
grammability (ISP). Once initial code is resident in the PSD, the
program code can be updated while the MCU is running, called
In-Application Programming (IAP). Also, Infineon C167CR
family users can utilize the DK4000 as an evaluation platform
for code development.
The DK4000 – C167 Development Board is specific to the Infi-
neon C167CR micro-controller family. However, other prolifer-
ation boards will be available. Check the website at
www.st.com/psd as to availability.
A COUPLE OF DEFINITIONS
In-System Programming (ISP) - A JTAG interface (IEEE 1149.1
compliant) is included on the PSD enabling the entire device to
be rapidly programmed while soldered to the circuit board
(Main Flash memory, Secondary Boot Flash memory, the PLD
and all configuration areas). This requires no MCU participa-
tion, so the PSD can be programmed or reprogrammed any-
time, anywhere, even while completely blank. The MCU is
completely bypassed.
In-Application Programming (IAP) – Since two independent
Flash memory arrays are included in the PSD, the MCU can ex-
ecute code from one memory while erasing and programming
the other. Robust product firmware updates in the field are pos-
sible over any communication channel (a few examples are
CAN, Ethernet, UART, J1850) using this unique architecture.
For IAP, all code is updated through the MCU.
