} The programming voltages of 25V, 21V and 12.5V are generated with the help of zener diodes ZD1, ZD2 and ZD3. ROM. } } A problem encountered in producing switch-mode supplies is the availability of certain passive components, particularly the inductor. The prototype delivered 12 V and an output current, Io, of up to 200 mA, more than enough for a flash-EPROM. EPROM, PROM & ROM 1.

That’s why only the first 8 address lines (256 bytes) are wired to switches! Use a single earthing point and decouple the IC directly at its points. When push-to-on switch S1 is pressed, IC2 generates a 50ms pulse, which is given to the program pin 18 of the ZIF SOCKET through switch S2. When push-to-on switch S1 is pressed, IC2 generates a 50ms pulse, which is given to the program pin 18 of the ZIF SOCKET through switch S2.

The EPROM Programmer presented here will program the standard 27 family of devices, from 2716 to 27512, and can be used with any computer which has an RS232 serial port. To burn code or data into EPROM, the ROM burner uses 12.5 volts or higher, depending on the EPROM type.
