HT23C040 Datasheet CMOS 512kx8-bit Mask Rom

Manufacturer: Holtek Semiconductor Inc

Overview: CMOS 512K´8-Bit Mask ROM.

General Description

The HT23C040 is a read-only memory with high performance CMOS storage device whose 4096K of memory is arranged into 524288 word by 8 bits.

For application flexibility, the chip enable and output enable control pins can be selected as active high or active low.

This flexibility not only allows easy interface with most microprocessors, but also eliminates bus contention in multiple bus microprocessor systems.
