1. INTRODUCTION
1.1 Purpose
This document is the Hardware User Guide for the STMicroelectronics’s STM32MP13x MPU based OSM v1.1
specification compatible Size-0 LGA module. This board is fully supported by iWave Systems Technologies Pvt. Ltd. This
Guide provides detailed information on the overall design and usage of the STM32MP13x OSM Module from a
Hardware Systems perspective.
1.2 OSM LGA Module Overview
The OSM V1.1 (“Open Standard Modules™”) is a future proof and versatile standard for small size, low-cost embedded
computer modules. Combining the following key characteristics like completely machine processible during soldering,
assembly and testing, Pre-tinned LGA package in different possible packages for direct PCB soldering without
connector.
The OSM Module definition targets application that requires low power, low cost, and high performance. The Modules
are used as building blocks for portable and stationary embedded systems. The core SoC and support circuits, including
DRAM, boot flash, power sequencing, SoC power supplies are concentrated on the Module. The Modules are used
with application specific Carrier Boards that implement other features such as audio CODECs, touch controllers,
wireless devices, etc. The modular approach allows scalability, fast time to market and upgradability while still
maintaining low costs, low power and small physical size.
STMicroelectronics’s STM32MP13x MPU based OSM LGA Module is rich with STM32MP13x features along with on
Module DDR3L, QSPI and comes in the smallest OSM form factor of 30mm x 15mm form factor (Size-0F). The Module
PCB has 188 contacts which can be mounted as LGA/BGA on OSM carrier card.

STM32MP13x MPU at 533MHz frequency. DDR3L part U1 is placed on Top side of the Module. The memory size in
default configuration is 5132MB. To customize the DDR3L memory size, contact iWave.
2.5.2 QSPI
The STM32MP13x OSM LGA Module supports 16Mb QSPI that can be used for storing the tf-a data. This is directly
connected to QUADSPI controller of the STM32MP13x MPU and operates at 1.8V (I/O supply).
The QSPI memory (U4) is physically located on Top side of the Module. The memory size of the QSPI flash can be
customised (max 16Mb) based on the requirement by contacting iWave Support Team.
