AT89c51 programmer | All About Circuits
Dec 22, 2014Whoever designed that circuit found the crystal they liked, read the crystal datasheet, saw that the crystal needs 22 pF capacitors and put those capacitors into the schematic. This is actually interesting choice of microcontroller. 89C51 RD2 has bootloader so you don't need programmer device, you connect the 89C51RD2 directly to computer and
Manual EPROM Programmer | Detailed Circuit Diagram Available
The programmer devices required for programming the electrically programmable read only memories (EPROMs) are generally expensive. Here is a low-cost EPROM programmer circuit to program binary data into 2716 and 2732 EPROMs. EPROM Programmer Circuit. The circuit uses timer NE555 (IC2) wired as a monostable. When push-to-on switch S1 is pressed
