2 / 17 page 6.42 IDT70V26S/L High-Speed 16K x 16 Dual-Port Static RAM Industrial and Commercial Temperature Ranges 2 Description The IDT70V26 is a high-speed 16K x 16 Dual-Port Static RAM. The IDT70V26 is designed to be used as a stand-alone 256K-bit Dual- Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32- bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. This device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using IDT’s CMOS high-performance technology, these devices typically operate on only 300mW of power. The IDT70V26 is packaged in a ceramic 84-pin PGA and 84-Pin PLCC. Pin Configurations(1,2,3) NOTES: 1. All VCC pins must be connected to power supply. 2. All GND pins must be connected to ground supply. 3. Package body is approximately 1.15 in x 1.15 in x .17 in. 4. This package code is used to reference the package diagram. 5. This text does not indicate orientation of the actual part-marking. 2945 drw 02 14 15 16 17 18 19 20 INDEX 21 22 23 24 11 10 9876 543 2 1 84 83 33 34 35 36 37 38 39 40 41 42 43 44 45 VCC GND I/O8L A8L 13 12 25 26 27 28 29 30 31 32 46 47 48 49 50 51 52 53 72 71 70 69 68 67 66 65 64 63 62 73 74 61 60 59 58 57 56 55 54 82 81 80 79 78 77 76 75 GND BUSYL GND IDT70V26J J84-1(4) 84-Pin PLCC Top View(5) A0L M/ S A0R I/O9L I/O10L I/O11L I/O12L I/O13L I/O14L I/O15L I/O0R I/O1R I/O2R VCC I/O3R I/O4R I/O5R I/O6R I/O7R I/O8R A7L A6L A5L A4L A3L A2L A1L BUSYR A1R A3R A4R A5R A6R A7R A2R |
