Introducing our newest Universal Willem EPROM programmer PCB5.0E SMD version! This is a brand-new and fully tested enhanced Dual Power (USB/AC) Willem Universal EPROM EEPROM programmer, PCB version PCB5.0SMD. We\'ve added support for those new 25 series SPI Flash Bios chips ! This board has many enhanced features, such as built-in PLCC32, FWH / LPC sockets, thus NO NEED to pay extra to purchase these optional adapters. The PCB layout is fully optimized and the digital circuitry is separated from the power supply circuit, thus reducing interference. High precision digital switching ICs are used to control the Vpp circuit ( vs cheap regular transistor controlled), thus dramatically improves the burning accuracy and reliability by multitudes. Quality components are used, for example, the high current tolerant coil is used to boost the robustness of the circuitry. Optional higher Vcc voltages (5.6v and 6.2v) will be available when an external AC power supply is used. This is very important when you want to smoothly and reliably burn those old CMOS and even older NMOS EPROM chips. This programmer can also read and burn EEPROM, FLASH, and Microcontroller (MCS-51, AVR and PIC family) chips. We also added software support for more Winbond chips !
