55 / 180 page Electrical Characteristics i.MX53xA Automotive and Infotainment Applications Processors, Rev. 1 Freescale Semiconductor 55 4.6.6.4 Examples of EIM Synchronous Accesses Figure 18 to Figure 21 provide few examples of basic EIM accesses to external memory devices with the timing parameters mentioned previously for specific control parameters settings. Figure 18. Synchronous Memory Read Access, WSC=1 1 t is the maximal EIM logic (axi_clk) cycle time. The maximum allowed axi_clk frequency is 133 MHz, whereas the maximum allowed BCLK frequency is 104 MHz. As a result, if BCD = 0, axi_clk must be ≤ 104 MHz. If BCD = 1, then 133 MHz is allowed for axi_clk, resulting in a BCLK of 66.5 MHz. When the clock branch to EIM is decreased to 104 MHz, other busses are impacted which are clocked from this source. See the CCM chapter of the i.MX53 Reference Manual for a detailed clock tree description. 2 BCLK parameters are being measured from the 50% point, that is, high is defined as 50% of signal value and low is defined as 50% as signal value. 3 For signal measurements “High” is defined as 80% of signal value and “Low” is defined as 20% of signal value. Last Valid Address Address v1 D(v1) BCLK ADDR DATA WE_B ADV_B OE_B BEy_B CSx_B WE4 WE5 WE6 WE7 WE10 WE11 WE13 WE12 WE14 WE15 WE18 WE19 |
