General Description
The A26E001A is a low operating current 262,144 x 8 bit CMOS MASK ROM and 32,768 x 8 bit CMOS SRAM integrated into one chip. It operates on a low power supply voltage from 1.8V to 3.3V, with two chip selects to enable the MASK ROM or SRAM independently. Inputs and three-state outputs are CMOS compatible and allow for direct interfacing with common system bus structures. Minimum standby power is drawn by this device when ROMCE and RAMCE are at a high level, independent of the other input levels. Data retention is guaranteed at a power supply voltage as low as 1.6V.
