Xeltek offers unique programming solutions for in-circuit programming (ISP). ISP is a technique where a programmable device is programmed after it is placed in a circuit board. Today's external memory chips and microcontrollers can be reprogrammed without being removed from the circuit, thus eliminating the extra handling step required during the manufacturing process for programming a device with an external programmer.

ISP applications could be tedious to support due to PCB board constraints. Through extensive experience with ISP applications, Xeltek engineers analyze and offer cost-effective solutions with quick turnaround time. ISP solution is beneficial because it

1. Allows programmable electronic chips to be programmed while installed in a complete system.

2. Allows engineering and manufacturing facilities to shorten the development cycle by integrating programming and testing into a single production phase.

3. Reduces the possibility of damaging leads of surface mount devices and damaging devices through electrostatic discharge (ESD).

4. Allows manufacturers to eliminate delays and not have to purchase preprogrammed chips from a chip vendor / distributor.

5. Is feasible to apply code or design changes in the middle of  a production run.

6. Allows the use of the Automatic Test Equipment (ATE) to perform operations on ISP devices and integrate operations with normal production test flow.
