In-System Programming
The ispPAC-POWR1208 is an in-system programmable device. This is accomplished by integrating all E
configuration memory and control logic on-chip. Programming is performed through a 4-wire, IEEE 1149.1 compli-
ant serial JTAG interface. Once a device is programmed, all configuration information is stored on-chip, in non-vol-
atile E
instructions are described in the JTAG interface section of this data sheet.
User Electronic Signature
The User Electronic Signature (UES), allows the designer to include identification bits or serial numbers inside the
device, stored in E
user to store unique data such as ID codes, revision numbers or inventory control codes.
Electronic Security
An Electronic Security Fuse (ESF) bit is provided to prevent unauthorized readout of the E
programmed, this cell prevents further access to the functional user bits in the device. This cell can only be erased
by reprogramming the device; this way the original configuration cannot be examined or copied once programmed.
Usage of this feature is optional.
Production Programming Support
Once a final configuration is determined, an ASCII format JEDEC file can be created using the PAC-Designer soft-
ware. Devices can then be ordered through the usual supply channels with the user’s specific configuration already
preloaded into the devices. By virtue of its standard interface, compatibility is maintained with existing production
programming equipment, giving customers a wide degree of freedom and flexibility in production planning.
Evaluation Fixture
The ispPAC-POWR1208 Design Kit includes an engineering prototype board that can be connected to the parallel
port of a PC using a Lattice ispDOWNLOAD cable. It demonstrates proper layout techniques for the ispPAC-
POWR1208 and can be used in real time to check circuit operation as part of the design process. LEDs are sup-
plied to debug designs without involving test equipment. Input and output connections as well as a “breadboard”
circuit area are provided to speed debugging of the circuit. The board includes an area for prototyping other circuits
