ELECTRICAL SPECIFICATIONS (G: INDUSTRIAL APPLICATIONS TA = -40 to +105 C) R01DS0193EJ0210 Rev.2.10 Mar 25, 2016 Page 78 of 106 (2) During communication at same potential (CSI mode) (master mode, SCKp... internal clock output) (TA = 40 to +105C, 2.4 V VDD 5.5 V, VSS = 0 V) HS (high-speed main) Mode Parameter Symbol Conditions MIN. MAX. Unit 2.7 V VDD 5.5 V 334 ns SCKp cycle time tKCY1 tKCY1 4/fCLK 2.4 V VDD 5.5 V 500 ns 4.0 V VDD 5.5 V tKCY1/2 24 ns 2.7 V VDD 5.5 V tKCY1/2 36 ns SCKp high-/low-level width tKH1, tKL1 2.4 V VDD 5.5 V tKCY1/2 76 ns 4.0 V VDD 5.5 V 66 ns 2.7 V VDD 5.5 V 66 ns SIp setup time (to SCKp ) Note 1 tSIK1 2.4 V VDD 5.5 V 113 ns SIp hold time (from SCKp ) Note 2 tKSI1 38 ns Delay time from SCKp to SOp output Note 3 tKSO1 C = 30 pF Note4 50 ns Notes 1. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp setup time becomes “to SCKp ” when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0. 2. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp hold time becomes “from SCKp ” when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0. 3. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The delay time to SOp output becomes “from SCKp ” when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0. 4. C is the load capacitance of the SCKp and SOp output lines. Caution Select the normal input buffer for the SIp pin and the normal output mode for the SOp and SCKp pins by using port input mode register 1 (PIM1) and port output mode registers 0, 1, 4 (POM0, POM1, POM4). Remarks 1. p: CSI number (p = 00, 01, 11, 20), m: Unit number (m = 0, 1), n: Channel number (n = 0, 1, 3) 2. fMCK: Serial array unit operation clock frequency (Operation clock to be set by the serial clock select register m (SPSm) and the CKSmn bit of serial mode register mn (SMRmn). m: Unit number (m = 0, 1), n: Channel number (n = 0, 1, 3)) |
