NEe Microcomputers, Inc. 2048 x 8 BIT STATIC CMOS RAM NEe f’PD446 f’PD446-1 pPD446-2 ~rn~[~~~ ~illrnW DESC RIPTION The IlPD446 is a high speed, low power, 2048 word by 8 bit static CMOS RAM fabricated using an advanced silicon gate CMOS technology. A unique circuitry technique makes the IlPD446 a very low operating power device which requires no clock or refreshing to operate. Minimum standby power current is drawn by this device when CE equals VCC independently of the other input levels. Data retention is guaranteed at a power supply voltage as low as 2V. The IlPD446 is packaged in a standard 24’pin dual-in-line package and is plug-in compatible with 16K EPROMs. FEATU RES • Single +5V Supply • Fully Static Operation – No Clock or Refreshing required • TTL Compatible – All Inputs and Outputs • Common I/O Using Three-State Output • OE Eliminates Need for External Bus Buffers • Max Access/Min Cycle Times Down to 120 ns • Low Power Dissipation, 45 mA Max Activel100 IlA [ … ]
