Page 31: Lpc Bus/Espi
LPC Bus/eSPI The conga-MA7 offers the LPC (Low Pin Count) bus by default. The LPC bus corresponds approximately to a serialized ISA bus yet with a significantly reduced number of signals and functionality. Due to the software compatibility to the ISA bus, I/O extensions such as additional serial ports can be easily implemented on an application specific carrier board using this bus. -
Page 32: Power Control
The module is kept in reset as long as the PWR_OK is driven by carrier board hardware. It is strongly recommended that the carrier board hardware drives the signal low until it is safe to let the module boot-up. Copyright © 2021 congatec GmbH MA70m102... - Page 33 Power Supply Implementation Guidelines Input power of 4.75 - 20 volt is the sole operational power source for the conga-MA7. The remaining necessary voltages are internally generated on the module using onboard voltage regulators. A carrier board designer should be aware of the following important information when designing a power supply for a conga-MA7 application: •...

Inrush and Maximum Current Peaks on VCC_5V_SB and VCC The inrush current on the conga-MA7 VCC_5V_SB power rail can go up as high as 6.13 A and as high as 27.94 A on VCC power rail (12 V) within a short time (approx. 150μs) and with a voltage rise time of 100μs. Sufficient decoupling capacitance must be implemented on the carrier board to ensure proper power-up sequencing. -
Page 35: Additional Features
The conga-MA7 offers an onboard eMMC 5.1 HS400 storage device with up to 64 GB storage capacity. The default eMMC storage capacity of each conga-MA7 variant is listed in section 1.1 "Options Information". Changes to the onboard eMMC may occur during the lifespan of the module in order to keep up with the rapidly changing eMMC technology. -
Page 36: Fan Control
Fan Control The conga-MA7 has additional signals and functions to further improve system management. One of these signals is an output signal called FAN_PWMOUT that allows system fan control using a PWM (Pulse Width Modulation) output. Additionally, there is an input signal called FAN_TACHIN that provides the ability to monitor the system's fan RPMs (revolutions per minute). -
