Samsung
4M-Bit (512Kx8) CMOS MASK ROM
Part no. KM23C4000P-15
Also on the chips PJWIWL55M A128 Korea
DESCRIPTION
The KM23C4000P is a fully static mask programmable ROM organized 524,288 x 8bit. It is fabricated using silicon gate CMOS process technology. This device operates with a 5V single power supply, and all inputs and outputs are TTL compatible. Because of its asynchronous operation, it requires no external clock assuring extremely easy operation. It is suitable for use in program memory of microprocessor, and data memory, character generator.
The KM23C4000P is packaged in a 32 P DIP
These genuine Samsung parts came to us as part of a lot of surplus stock, purchased from a large OEM, they may have been in storage for a while (the date code appears to be 128?) but they are absolutely as new and are stored with us in their original tubes and outer Toshiba box.
Purchasers will receive their chip (‘s) correctly packed in anti static packaging.
These are now discontinued in the 32 P DIP – for datasheet on the flatpack 32TSOP1 package version copy and paste:-
