Also, three separate chip select (CE) connections are used to independently enable the three bytes. The modules can be supplied in a variety of access time values from 8nSEC to 20nSEC in CMOS or BiCMOS technology. The Accutek module is designed to have a maximum seated height of 0.500 inch to provide for the lowest height off the board. The modules conform to JEDEC - standard sizes and pin-out configurations. Using two pins for module memory density identification, PD0 and PD1, minimizes interchangeability and design considerations when changing from one module size to the other in customer applications. 33 MECHANICAL DIMENSIONS ORDERING INFORMATION Inches PART NUMBER CODING INTERPRETATION Position 1 2 3 4 5 6 7 8 Top View ZIP 3 5 59 60 63 64 1 3.595 3.605 CL CL 0.100 TYP 64 0.350 MAX ACCUTEK MICROCIRCUIT CORPORATION BUSINESS CENTER at NEWBURYPORT 2 NEW PASTURE ROAD, SUITE 1 NEWBURYPORT, MA 01950-4054 PHONE: 978-465-6200 FAX: 978-462-3396 E-mail: [email protected] Internet: www.accutekmicro.com CL CL 64K x 24, 12 nSEC SRAM Module, ZIP Configuration 0.100 TYP EXAMPLES: .050 x .050 ANGLE NOTCH 0.500 MAX 0.050 TYP The numbers and coding on this page do not include all variations available but are shown as examples of the most widely used variations.
