Using the ATE Port to Control ISP Programmers


In-system / In-circuit programming (ISP) is the ability of programming an IC chip that is already soldered on the circuit board using serial programming algorithms. In-system programming helps eliminate tedious programming stages prior to assembling the system and reduce multiple tasks to a single production phase.

Since there is no need to desolder an IC chip, code or design changes are more convenient by simply reprogramming the chip already on the printed circuit board (PCB). SuperProIS01 is Xeltek's portable ISP programmer. It supports most ISP protocols like I2C, SPI, UART, BDM, MW, JTAG, CAN, RS232 etc. while also having the ability to operate in stand-alone mode using a secure digital (SD) card. SuperProIS01 comes with an Automated Test Equipment (ATE) interface which allows operating and controlling programmers through external signals.
An ATE control port is used for communication with an external host or integration into the automatic programming / test equipment. Beside using the built-in keyboard, users can also operate SuperProIS01 programmers through the ATE interface. In order to ensure security and accuracy of signals between the two equipments, the ATE interface adopts opto-coupling device to isolate signals. Note that while using the ATE interface, it is required to set the power voltage and appropriate reference voltage point correctly for the external equipment.
