TopJTAG Flash Programmer

A universal in-circuit indirect programmer of parallel NOR flash memories. Programs flash memories connected to any JTAG-compliant device by manipulating the device's pins using boundary-scan technology.
Indirect programming using boundary-scan
By utilizing boundary-scan (JTAG) test logic on a chip connected to flash memory (e.g.

CPU, FPGA, CPLD, ASIC), TopJTAG Flash Programmer 'detaches' the chip's core from its pins and manipulates pins signals in order to communicate with flash memory.
No dependence on logic inside JTAG IC
The chip connected to flash memory could be any JTAG-compliant IC. TopJTAG Flash Programmer works independently on any logic inside the JTAG chip. There is no need to load any code or firmware into the JTAG chip.
