34 / 54 page µµµµPD48288209AF1, µµµµPD48288218AF1, µµµµPD48288236AF1 R10DS0254EJ0101 Rev. 1.01 Page 34 of 53 Jan. 15, 2016 2.14 Operation with Multiplexed Address In multiplexed address mode, the address can be provided to the µPD48288209/18/36AF1 in two parts that are latched into the memory with two consecutive rising clock edges. This provides the advantage that a maximum of 11 address balls are required to control the µPD48288209/18/36AF1, reducing the number of balls on the controller side. The data bus efficiency in continuous burst mode is not affected for BL=4 and BL=8 since at least two clocks are required to read the data out of the memory. The bank addresses are delivered to the µPD48288209/18/36AF1 at the same time as the WRITE command and the first address part, Ax. This option is available by setting bit A5 to “1” in the mode register. Once this bit is set, the READ, WRITE, and MRS commands follow the format described in Figure 2-26. See Figure 2-28. Power-Up Sequence in Multiplexed Address Mode for the power-up sequence. Figure 2-26. Command Description in Multiplexed Remarks 1. Ax, Ay : Address BA : Bank Address 2. The minimum setup and hold times of the two address parts are defined tAS and tAH. CK# CK WE# REF# CS# READ WRITE Don't care MRS Ax Ay Ay Ax Ay Ax BA BA ADDRESS BANK ADDRESS |
