DESCRIPTION
The PD75P308 is a model of the PD75308 equipped with a one-time PROM or EPROM instead of an
internal mask ROM.
Two types are available as the PD75P308. The one-time PROM type is ideal for production of a small
quantity of many different types of application systems as data can only be written once to the one-time
PROM of this type. Programs can be written and rewritten to the built-in EPROM type making it ideal
for system evaluation.
Detailed functions are described in the followig user's manual. Be sure to read it for designing.

Page 11: Writing And Verifying Prom (Program Memory)
PD75P308 3. WRITING AND VERIFYING PROM (PROGRAM MEMORY) The program memory of the PD75P308 is a PROM of 8064 x 8 bits. To write data to or verify the contents of this PROM, the pins listed in the table below are used. Note that no address input pins are provided because the address is updated by the clock input through the X1 pin. -
Page 12: Program Memory Write Procedure
PD75P308 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 and V pins. -
Page 13: Program Memory Read Procedure
PD75P308 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 and V pins. -
Page 14: Erasure ( Pd75P308K Only)
PD75P308 3.4 ERASURE ( PD75P308K ONLY) The contents of the data programmed to the 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.s/cm (= ultraviolet ray intensity x erasure time). -
