Bus timing (2 of 3)

Condition 1: When using the CS area controller (CSC).

VCC = VCC_DCDC = VBATT = 1.62 V to 3.6 V, VCC2 = 1.62 V to 3.63 V

BCLK = 8 to 120 MHz, BCLKA = 8 to 120 MHz, EBCLK = 8 to 60 MHz (When VCC = VCC_USB = VBATT = 2.70 to 3.63 V)

BCLK = BCLKA = 8 to 60 MHz, EBCLK = 8 to 30 MHz (When VCC = VCC_USB = VBATT = 1.62 to 3.63 V)

Output load conditions: VOH = VCC × 0.5, VOL = VCC × 0.5, C = 30 pF

EBCLK: High drive output is selected in the port drive capability bit in the PmnPFS register.

Others: Middle drive output is selected in the port drive capability bit in the PmnPFS register.

Condition 2: When using the SDRAM area controller (SDRAMC).

BCLK = SDCLK = 8 to 125 MHz, BCLKA = SDCLK = 8 to 133 MHz

VCC = VCC_DCDC = VBATT = 3.0 to 3.63 V, VCC2 = 1.62 V to 3.63V

Output load conditions: VOH = VCC × 0.5, VOL = VCC × 0.5, C = 15 pF

SDCLK: High-speed high drive output is selected in the port drive capability bit in the PmnPFS register.

Others: High drive output is selected in the port drive capability bit in the PmnPFS register.

Condition 3: When using the SDRAM area controller (SDRAMC) and CS area controller (CSC) simultaneously.

BCLK = SDCLK = 8 to 66 MHz, BCLKA = SDCLK = 8 to 66 MHz

VCC = VCC_DCDC = VBATT = 3.0 to 3.63 V, VCC2 = 1.62 V to 3.63V

Output load conditions: VOH = VCC × 0.5, VOL = VCC × 0.5, C = 15 pF

EBCLK/SDCLK: High drive output is selected in the port drive capability bit in the PmnPFS register.

Others: Middle drive output is selected in the port drive capability bit in the PmnPFS register.
