IDT71016

CMOS Static RAM 1 Meg (64K x 16-Bit) Features 64K x 16 advanced high-speed CMOS Static RAM Equal access and cycle times – Commercial and Industrial: 12/15/20ns One Chip Select plus one Output Enable pin Bidirectional data inputs and outputs directly TTLcompatible Low power consumption via chip deselect Upper and Lower Byte Enable Pins Commercial and industrial product available in 44-pin Plastic SOJ package and 44-pin TSOP package IDT71016 ◆ ◆ Description The IDT71016 is a 1,048,576-bit high-speed Static RAM organized as 64K x 16. It is fabricated using IDT’s high-perfomance, high-reliability CMOS technology. This state-of-the-art technology, combined with innovative circuit design techniques, provides a cost-effective solution for high-speed memory needs. The IDT71016 has an output enable pin which operates as fast as 7ns, with address access times as fast as 12ns. All bidirectional inputs and outputs of the IDT71016 are TTL-compatible and operation is from a single 5V supply. Fully static asynchronous circuitry is used, requiring no clocks or refresh for operation. The IDT71016 is packaged in a JEDEC standard 44-pin Plastic SOJ and 44-pin TSOP Type II. ◆ ◆ ◆ ◆ ◆ Functional Block Diagram OE Output Enable Buffer A0 - A15 Address Buffers Row / Column Decoders I/O 15 Chip Enable Buffer Sense Amps and Write Drivers 8 Low Byte I/O Buffer 8 8 High Byte I/O Buffer 8 , CS I/O 8 WE Write Enable Buffer 64K x 16 Memory Array 16 I/O 7 I/O 0 BHE Byte Enable Buffers BL...
