6116A: 11/8/89 Revision: Monday, November 8, 1993 www.DataSheet4U.com Features D D D D D D D Automatic powerĆdown when deselected CMOS for optimum speed/power High speed Ċ 20 ns Low active power Ċ 550 mW Low standby power Ċ 110 mW TTLĆcompatible inputs and outputs Capable of withstanding greater than 2001V electrostatic discharge The CY6116A and CY6117A are highĆ performance CMOS static RAMs orgaĆ nized as 2048 words by 8 bits. Easy memoryexpansionisprovidedbyanactive LOW chip enable (CE) and active LOW output enable (OE), and threeĆstate drivĆ ers. The CY6116A and CY6117A have an automatic powerĆdown feature, reducing the power consumption by 83% when deĆ selected. Writingtothedeviceisaccomplishedwhen the chip enable (CE) and write enable (WE) inputs are both LOW. Data on the I/Opins(I/O 0 throughI/O 7)iswritteninto Functional Description the memory location specified on the adĆ dress pins (A 0 through A 10). ReadingthedeviceisaccomplishedbytakĆ ing chip enable (CE) and output enable (OE) LOW while write enable (WE ) reĆ mains HIGH.Undertheseconditions,the contents of the memory location specified on the address pins will appear on the I/O pins. The I/O pins remain in highĆimpedance state when chip enable (CE ) is HIGH or write enable (WE) is LOW. The CY6116A and CY6117A utilize a die coat to insure alpha immunity. 2K x 8 Static RAM CY6116A CY6117A Logic Block Diagram A7 A6 A5 A4 A3 A2 A1 1 2 3 4 5 6 7 8 9 10 11 12 Pin Configurations DIP/SOJ Top View 24 23 22 21 20 19 6116A 18 17 16 15 14 13 VCC A8 A9 WE OE A 10 CE I/O 7 I/O 6 I/O 5 I/O 4 I/O 3 A3 A2 NC NC A1 A0 I/O 0 5 6 7 8 9 10 11 6116A 4 A4 A7 V CC LCC Top View A8 3 2 1 28 27 26 25 24 23 22 21 20 19 1213 14 151617 18 1 I/O 2 GND I/O 3 I/O 4 I/O 5 I/O 6 WE OE A 10 NC NC CE I/O 7 A9 6116A-3 A5 A6 I/O 0 INPUT BUFFER A0 I/O 0 I/O 1 GND ROW DECODER A9 A8 A7 A6 A5 A4 I/O 2 SENSE AMPS 6116A-2 128 x 16 x 8 ARRAY I/O 3 NC NC NC NC I/O 5 4 A6 A5 A4 A3 A2 5 6 7 8 9 10 11 12 13 3 2 1 32 31 30 29 28 27 26 A8 A9 NC WE OE A 10 CE I/O 7 I/O 6 CE WE COLUMN DECODER OE POWER DOWN I/O 6 6117A I/O 7 A1 A0 NC A3 A2 A1 A0 6116A-1 I/O 0 14 15 16 17 1819 20 GND NC I/O 4 I/O 5 I/O 1 I/O 2 I/O 3 NC A7 I/O 4 V CC LCC Top View 25 24 23 22 21 I/O A10 I/O 1 I/O 2 6116A-4 Selection Guide Maximum Access Time (ns) Maximum Operating Current (mA) Maximum Standby Current (mA) Commercial Military Commercial Military D 6116A-20 6117A-20 20 100 6116A-25 6117A-25 40/20 25 100 125 20 40 D 6116A-35 6117A-35 35 100 100 20 20 6116A-45 6117A-45 45 100 100 20 20 6116A-55 6117A-55 55 80 100 20 20 Cypress Semiconductor Corporation 3901 North First Street 1 San Jose D CA 95134 D 408-943-2600 February 1988 - Revised December 1992 6116A: 11/8/89 Revision: Monday, November 8, 1993 CY6116A CY6117A Maximum Ratings www.DataSheet4U.com (Above which the useful life may be impaired.
