MCM6726C

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MCM6726C/D 128K x 8 Bit Fast Static Random Access Memory The MCM6726C is a 1,048,576 bit static random access memory organized as 131,072 words of 8 bits. Static design eliminates the need for external clocks or timing strobes. Output enable (G) is a special control feature that provides increased system flexibility and eliminates bus contention problems. This device meets JEDEC standards for functionality and revolutionary pinout, and is available in a 400 mil plastic small–outline J–leaded package. Single 5 V ± 10% Power Supply Fully Static — No Clock or Timing Strobes Necessary All Inputs and Outputs Are TTL Compatible Three State Outputs Fast Access Times: 6, 7 ns Center Power and I/O Pins for Reduced Noise MCM6726C WJ PACKAGE 400 MIL SOJ CASE 857A–02 PIN ASSIGNMENT A A A A E DQ DQ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 A A A A G DQ DQ VSS VCC DQ DQ A A A A A BLOCK DIAGRAM A A A A A A A A DQ INPUT DATA CONTROL DQ A A COLUMN I/O COLUMN DECODER ROW DECODER MEMORY MATRIX 512 ROWS x 256 x 8 COLUMNS VCC VSS VCC VSS DQ DQ W A A A A PIN NAMES A . . . . . . . . . . . . . . . . . . . .
