Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MCM6708A/D 64K x 4 Bit Static RAM The MCM6708A is a 262,144 bit static random access memory organized as 65,536 words of 4 bits, fabricated using high–performance silicon–gate BiCMOS technology.
Static design eliminates the need for external clocks or timing strobes.
The MCM6708A is available in a 300 mil, 24 lead plastic surface–mount SOJ 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: MCM6708A–8 = 8 ns MCM6708A–10 = 10 ns MCM6708A–12 = 12 ns MCM6708A J PACKAGE 300 MIL SOJ CASE 810A–02 PIN ASSIGNMENT 1 2 3 4 5 6 7 8 9 10 11 12 VCC A15 A14 A13 A12 A11 A10 DQ0 DQ1 DQ2 DQ3 W A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 E VSS 24 23 22 21 20 19 18 17 16 15 14 13 BLOCK DIAGRAM A A A A A A A A ROW DECODER MEMORY MATRIX 256 ROWS x 256 x 4 COLUMNS DQ0 • • • DQ3 A A A • • • INPUT DATA CONTROL COLUMN I/O COLUMN DECODER • • • PIN NAMES A0 – A15 .
