FREEDM 84A1024L ASSP Telecom Standard Product Data Sheet
Function
Re-Sequencing SDRAM Bank Select. The bank select
signal determines which bank of a dual/quad bank Re-
Sequencing SDRAM chip is active. RSBS[1:0] is generated
along with the row address when RSRASB is asserted low.
RSBS is updated on the rising edge of SYSCLK.
Re-Sequencing SDRAM Data. The bi-directional Re-
Sequencing SDRAM data bus pins interface directly with
the Re-Sequencing SDRAM data ports.
RSDAT[31:0] is updated/tristated on the rising edge of
SYSCLK.
Drives DQMH and DQML inputs of all SDRAMs. During the
SDRAM initialization sequence this signal is set “high”.
Otherwise it is “low” at all times as the DRAM Controllers
do not utilize the “masking” functionality of the memories.
DQM is updated on the rising edge of SYSCLK.
