µ PD75P308 11 Pin Name Function V PP Applies voltage when program memory is written/verified (normally, at V DD potential) These pins input clock that updates address when program memory is written/verified. To X2 pin, input signal 180º out of phase in respect to signal to X1 pin.
µ PD75P308 12 3.2 PROGRAM MEMORY WRITE PROCEDURE The program memory write procedure is as follows. High-speed program memory write is possible. (1) Ground the unused pins through pull-down resistors. The X1 pin must be low. (2) Supply 5 V to the V DD and V PP pins.
µ PD75P308 13 3.3 PROGRAM MEMORY READ PROCEDURE The contents of the program memory can be read in the following procedure. (1) Ground the unused pins through pull-down resistors. The X1 pin must be low. (2) Supply 5 V to the V DD and V PP pins. (3) Wait for 10 microseconds.
µ PD75P308 14 3.4 ERASURE ( µ PD75P308K ONLY) The contents of the data programmed to the µ PD75P308 can be erased by exposing the window of the program memory to ultraviolet rays. The wavelength of the ultraviolet rays used to erase the contents is about 250 nm, and the quantity of the ultraviolet rays necessary for complete erasure is 15 W.
