The Standalone mode is ideal for production environments not only because it doesn't require any technical skill to use, but for its security features. You can set up a passkey sequence that must be entered to begin programming, and can set it to require a passkey sequence after a set number of successful programming operations. This ensures against technological espionage, as you can keep track of exactly how many parts were programmed versus how many you have in production.

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.

The included WL-ISP-U1 in-system programming adapter's 10 flying leads are all labeled, so you can be sure that you're putting the correct wire on the correct pin when you need to program your devices in circuit.
