Holtek Semiconductor HT23C010
The HT23C010 is a read-only memory with high performance CMOS storage device whose 1024K of memory is arranged into 131072 words 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.| Part No. | HT23C010 |

GENERAL DESCRIPTION
An additional feature of the HT23C010 is its ability to enter the standby mode whenever the chip enable (CE/CE) is inactive, thus reducing current consumption to below 30µA. The combination of these functions makes the chip suitable for high density low power memory applications. Block Diagram 1 24th Aug ’98 HT23C010 Pin Assignment PinDESCRIPTION
