WHY WELLON ?   The comparison support devices list of WELLON series programmer    Technical advantages    Weilei has been making Wellon series device programmers since 1998 and is well experienced in this business. Up to    13,000 chips in various packages from over 80 manufacturers are supported at highest reliability and speed. Wellon is built    with the most advanced features you can imagine. (Details below)  Total solution    Various models are provided to meet your needs in low cost and high end, engineering and production, cluster, PC-hosted    use.  Advanced features      Wellon is designed with the state-of-art hardware architecture with on-board high speed CPU, RTOS, FPGA, CPLD and high      quality universal pin-drivers. These enable it an advanced programmer.    ·The 48 pins powerful universal pin-drivers can lead programmable precision voltage signals, GND, CLK, to any pin. A       FPGA provides full I/O signals (level programmable from 1.5v to 5v) to up to 48 pins. These make the programmer truly       universal: Both current and future, 5v and low voltage devices are supported. Different devices in 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 ZIF48 socket as a standard accessory. The benefits brought to user by this are the rapid       availability of device support by simply d/l new algorithms and saving in adapter purchasing by the limited types.    · Semiconductor 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 uS timing resolution.       Special design was made to eliminate overshoot and ground bounce.    · Algorithms are performed with state machine architecture constructed with FPGA to achieve a ultra-high programming         speed.      · Insertion and continuity check are performed before programming to protect devices from damaged due to operation         error.      · Over current and over voltage protection is acted to each pin to protect programmer hardware from destroy due to bad         chip short circuit and ESD.      · User-friendly s/w features. Auto-count, batch command, Insertion-and-start. Windows compatible s/w.   Which model to buy ?
