TOSHIBA MOS MEMORY PRODUCT
4M BIT (512K WORD X 8 Bin CMOS MASK ROM
SILICON GATE CMOS
TC534000P
OESCR! PTI ON
The TC534000P is a 4,194,304 bits read only memory organized as 524,288 words by
8 bits with a low bit cost, thus being suitable for use in program memory of micro-
processor, and data memory, especially character generator. The TC534000P using CHOS
technology is most suitable for low power applications where battery operations are
required.
The TC534000P has one programmable chip enable input CE/CE for device selection.
The TC534000P is moulded in a 32 pin standard plastic package, 0.6 inch in width.
