Power & Reset

Power Architecture

The Hailo 15’s power is a single 5V source. It uses Discreet power converters to generate its power rails. The following figure describes the power architecture and power up sequencing.

The power architecture main features are:

• Single 5V power source.

• 1.8V output up to 1A (Need to calculate system and SOM power).

Power Consumption

Hailo 15 SOM Power Table:

Reset

The Hilo 15 power is monitored by a voltage supervisor.

A reset can be triggered by an external reset signal (Switch) or the internal power fail. There is a pull-up on the SOM.

Hailo 15 Integration Manual

Power Up Sequence

The Hailo 15 is sourced by a single 5V input. All power sequences are supported on the SOM.

When using the SOM 1.8V output there is no need to consider its power sequence. If an external power source is used for the 1.8V, it needs to be power according to the power sequence rules.

Booting Options

The Hailo 15 support boot from a FLASH (QSPI) memory or from UART IF (UART1).

The Hailo 15 has one bootstrap pin, which select the boot-up interface of the M4 MCU.

The bootstrap pin, H_I2S_SDO, is being sampled with NRESET and should remain stable during the reset process.

The signal H_I2S_SDO is available on J5001-3 as a bootstrap pin and on J7-53 as an audio interface. However, one can use only one of the signal locations.

To check the boot sequencing please refer to the Hailo 15 datasheet.

I2C Interfaces

The Hailo 15 uses I2C0 interface for its internal configurations.

The Hailo 15 uses I2C0 interface for its internal configurations.

GPIO Interfaces

The Hailo 15 uses some GPIO signals for its internal controls. Some of the signals are of the CPU and others are of the IO Expender. The following table describes the GPIO allocation.

Hailo 15 SOM Debugging Capability

The Hailo 15 SOM supports two main debugging interfaces:

• UART interface

• JTAG interface

The UART interface is a null modem interface that is internally pulled up and supports using UART1 TX/RX signals available on J7-52 and J7-54.

The UART interface is optional to use and mentioned here since most of the software infrastructure used in Carrier EVK uses those two signals for debugging.

JTAG interface is on the Hailo 15 SOM and is exposed as test pins on components side. Following is a snapshot of the test points and its connectivity traces:

Hailo 15 Typical Power Consumption

Hailo 15 SOM Mechanical Description

Note the following details:

• The carrier board must use the same footprint as in the above mechanical footprint.
  Since this is a TOP VIEW of the print side of the Hailo 15 SOM, the diagram above describes the dimensions and placement of the board-to-board headers, mechanical holes and boundaries of the Hailo 15, as-is.

• J5002 (J9 on Hailo 15) is the main board-to-board header (bottom side in the diagram).

• J8004 (J7 on Hailo 15)is the second board-to-board header (upper side in the diagram).

• J5001 is the third board-to-board header (right side in the diagram).

• In case 1.5mm mating height was chosen, then the Hailo 15 requirement would be that all area beneath it on the carrier will be all dedicated ONLY for the board-to-board connectivity; no other components are allowed.
  In case higher mating is chosen, then 1.5mm should be reserved for the Hailo 15. For instance, if 3.5mm mating height is chosen, then 1.5mm is dedicated to the Hailo 15 print side components and the remaining 2mm for the carrier components underneath the Hailo 15.
