complete mainframe usb mouth power supply work, circumscribing forsook the / ac dc adapter, making machine weight lighter and more small, easy to carry. Īttainment approximation 's burning speed, automatically detect pin access to undesirable, ensure the programming safe and efficient, all power device used low manufacturing, abopt lower power consumption. 'RF-3148 usb programmer is full drive intelligent general programmer, it brings together xinrun fly more than ten years experience in design development, periof two years development accomplish.Įlaborate the products with all kinds of device programming needed all drive resource, including 48pin socket, road power supply voltage, burn programmed write voltage controlled programmed / i o signal, revisions, bordels oscillation clock, noise filter, surge strangulating etc, user secondary hardware ( adapter input ) reduses to minimum overhead. there's two claimed additional security measures for at89c5x: 'otp security' and 'data line killing''

however the documentation indicates that the latter requires an adapter that's unobtainium. 'this (no longer available) RunFei RF-3148 programmer I have has a 'Read secured IC' function and a 'Special protect' function for at89c52. Lord_Nightmare: '.the rf-2148 (which runfei 'recalled' and had some very broken english explanation why).'īalrog: 'if you can fine an rf-2148 it doesn’t need the adapter' Henry was in luck and was able to read and duplicate all the PLDs for this board.' The software for the programmer allows for some early PLDs with security issues to be copied regardless of the security bit being set. 'Luckily the PLDs were early GALs which could have their code extracted using a Run-Fei RF-2148USB IC programmer.
