Figure 30: eMMC reference circuit
For the current of VCC_eMMC and VCCQ_1V8, users should better refer to the related datasheet of
eMMC which is used. The listed current of 500mA and 300mA are just for your reference.
SD/MMC/eMMC card layout guide lines:
Protect SD card signals from noisy signals (clocks, SMPS, etc.).
Up to 200 MHz clock rate, 50 Ω nominal, ±10% trace impedance
CLK to DATA/CMD length matching < 1 mm
Total routing length < 50 mm
Spacing to all other signals = 2x line width
Bus capacitance < 10 pF
3.10 I2C Interface
MODULE provides a I2C interface compatible with I2C specification, version 5.0, with clock rate up to 400
kbps. Its operation voltage is 1.8V.
The following figure shows the I2C bus reference design.
