MPC2004 ? mpc2005 61 motorola fast sram advance information 256kb and 512kb burstram ? secondary cache modules for powerpc ? prep/chrp platforms the MPC2004 and mpc2005 are designed to provide burstable, high perfor - mance 256kb/512kb l2 cache for the powerpc 60x microprocessor family in conformance with the powerpc reference platform (prep) and the powerpc common hardware reference platform (chrp) specifications. the modules are configured as 32k x 72 and 64k x 72 bits in a 182 (91 x 2) pin dimm format. each module uses four of motorola' s 5 v 32k x 18 or 64k x 18 burstrams and a 5 v cache t ag ram configured as 16 k x 1 2 for tag field plus 16 k x 2 for valid and dirty status bits. bursts can be initiated with the sramads signal. subsequent burst address - es are generated internal to the burstram by the sramcnten signal. write cycles are internally self timed and are initiated by the rising edge of the clock (clkx) inputs. eight write enables are provided for byte write control. presence detect pins are available for auto configuration of the cache control. a serial eeprom is optional to provide more indepth description of the cache module. the module family pinout will support 5 v and 3.3 v components for a clear p ath to lower voltage and power savings. both power supplies must be connected. these cache modules are plug and pin compatible with the mpc2006, a 1mb synchronous module also designed for the prep and chrp specifications. they are also compatible with the mpc2007 and mpc2009, 256kb and 1mb re - spectively, asynchronous cache modules. ? powerpcstyle burst counter on chip ? flowthrough data i/o ? module requires both 3.3 v and 5 v power supplies ? multiple clock pins for reduced loading ? all cache data and tag i/os are lvttl (3.3 v) compatible ? three state outputs ? byte write capability ? fast module clock rates: 66 mhz ? fast sram access times: 10 ns for tag ram match 9 ns for data ram ? decoupling capacitors for each fast static ram ? high quality multilayer fr4 pwb with separate power and ground planes ? 182 pin card edge module ? burndy connector, part number: elf182jsc3z50 burstram is a trademark of motorola.burstram is a trademark of motorola. powerpc is a trademark of international business machines corp. this document contains information on a new product. specifications and information herein are subject to change without notice. order this document by MPC2004/d semiconductor technical data MPC2004 mpc2005 5/95 ? motorola, inc. 1995
