For those of you that would prefer to prototype with SRAM rather than LPDDR, Avnet has a compatible SRAM module that plugs onto the MXP (J1) header. You can find this module at
www.em.avnet.com/mxp-sram
It includes a 1 MB (1 M x 8) MicroPower Cypress SRAM.
Cypress CY62158EV30LL-45ZSXI (http://www.cypress.com/?mpn=CY62158EV30LL-45ZSXI)
