The programmer is designed using state-of-art hardware architecture with on-board high-speed CPU, RTOS, FPGA, CPLD and high-quality universal pin-drivers. The universal pin-drivers can route programmable precision voltage signals, GND and CLK to any pin. An FPGA provides full I/O signals (level programmable from 1.5V to 5V) to up to 48 pins. This makes the programmer truly universal: Both current and future 5V and low-voltage devices are supported. Different devices in the same package share one adapter. For example, the only QFP44 adapter (WL-TQFP44-U1) supports all MCUs, PLDs and memory. All DIL devices are supported directly with the standard ZIF48 socket.

Manufacturer-approved algorithms, precision and clean signals promise high programming yield. Algorithm waveform is generated by hardware offering 0.01V programming voltage resolution and 1-microsecond timing resolution. Special design was made to eliminate overshoot and ground bounce. Algorithms are performed with state-machine architecture constructed with an FPGA to achieve an ultra-high programming speed.

Insertion and continuity check are performed before programming to protect devices from damage due to operator error. Over-current and over-voltage protection is enacted to each pin to protect the programmer hardware from damage due to bad chip short circuit and ESD.
