What is in-system programming (ISP)?
In-system programming (ISP), also known as in-circuit programming, refers to the ability to program programmable components such as microcontrollers, flash memory, or programmable logic devices directly in electronic products. These semiconductors contain the respective instructions, data, or input and output commands for their operation. The software or firmware is transferred to the chip via a programming interface (e.g., JTAG, SWD, SPI, or UART) without having to remove it from the circuit.
In the past, flash programming required removing the microcontroller or other components from the target application and inserting them into an external programming device in order to equip them with functions. In some cases, this was even done by external contract manufacturers. This made the production process very costly and time-consuming. With ISP, on the other hand, programming takes place in the line after the ICs have been mounted on an assembled board.
This illustration shows how a wide variety of target devices can be programmed using ISP programming. For example, it is possible to transfer user data directly via the debug interface, write to FPGAs or CPLDs via JTAG connect, program the embedded flash memory using the microcontroller, or stream programmable content via a high-performance communication interface (e.g., USB or LAN).
Generated programs, i.e., firmware, are automatically transferred to the internal non-volatile memory via a flash programmer. This technology is now standard in electronics development.
