MX23C8000 8M-BIT [1M x 8] CMOS MASK ROM FEATURES • • • • • • 1M x 8 organization Single +5V power supply Fast access time : 100/120/150/200ns Totally static operation Completely TTL compatible Operating current : 25mA • Standby current : 15uA • Package - 32 pin plastic DIP - 32 pin plastic SOP - 32 pin plastic PLCC - 32 pin plastic TSOP GENERAL DESCRIPTION The MX23C8000 is a 5V only, 8M-bit, Read Only Memory. It is organized as 1M words by 8 bits, operates from a single +5V supply, has a static standby mode, and has an access time of 100/120/150/200ns. It is designed to be compatible with all microprocessors and similar applications in which high performance, large bit storage and simple interfacing are important design considerations. MX23C8000 offers automatic power-down, with powerdown controlled by the chip enable (CE) input. When CE goes high, the device automatically powers down and remains in a low-power standby modes as long as CE remains high.
