com Interfacing Cypress MoBL® Dual-Port to Intel® PXA272 Embedded Processor Introduction The PXA272 Embedded Processor of the Intel® PCA processor family is an integrated system-on-a-chip microprocessor for high performance, dynamic and low-power portable handheld and handset devices.
The Intel PXA272 processor includes a memory interface that gives designers more flexibility as it supports a variety of external memory types.
CYDM256A16 is an asynchronous MoBL® Dual-Port memory from Cypress Semiconductor.
It has a 256-Kbit shared memory array with two 16-bit data buses.
The shared memory structure allows independent access from both ports to 32K address locations.
The device is available in -35 and -55 speed grades in both commercial and industrial temperature ranges.
Internal arbitration logic is also available to decide which port gets access when both ports try to access the same memory location at the same time.
The MoBL Dual-Port can act as an interconnect between...
