This document is the Hardware User Guide for the Renesas’s RZ/G2UL, RZ/FIVE and RZ/A3UL Application processor
based on OSM v1.1 specification based 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 Renesas’s RZ/A3UL, G2UL and
FIVE 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 key characteristics like completely machine processible during soldering, assembly
and testing, Pre-tinned LGA package for direct PCB soldering without connector.
The OSM Module definition targeting application that requires low power, low costs, 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.
Renesas’s RZ/G2UL, RZ/FIVE and RZ/A3UL based OSM LGA Module is rich with Renesas features along with on SOM
DDR4, eMMC and comes in compact 30mm x 45mm form factor (OSM Size M). The Module PCB has 476 contacts
which can be mounted as LGA/BGA on the OSM Carrier Card.

2.4 PMIC with RTC
The RZ/G2UL, RZ/FIVE or RZ/A3UL OSM LGA uses the DA9062-52AM1 (U8) PMIC from Renesas for module power
management. The DA9062-52AM1 PMIC features four high efficiency Buck Regulators and four Linear regulators. It is
a programable power management integrated circuit (PMIC) that provides a highly programmable/configurable
architecture with fully integrated power devices and built-in one-time programmable memory stores key start up
configurations, drastically reducing external components typically used to set output voltage and sequence of external
regulators.
The DA9062-52AM1 PMIC is pre-programmed as per the voltage, power sequence and other requirements of
RZ/G2UL, RZ/FIVE or RZ/A3UL MPUs. The RIIC0 I2C from the RZ/G2UL, RZ/FIVE or RZ/A3UL MPU is used connected to
the PMIC. The I2C slave address of the PMIC is 0x58.

2.5 Memory
2.5.1 DDR4 RAM
The RZ/G2UL, RZ/FIVE or RZ/A3UL OSM LGA Module can support up to 4GB DDR4 RAM memory using the 16bit
DDR_CH0 channel of the MPU. The DDR4 part U4 placed at the top of the board can operate at speed of up to 1.2GHz.
By default, in RZ/G2UL and RZ/A3UL, the default DDR density is 2GB and in RZ/FIVE, the density is 1GB. To customize
the DDR4 memory size, contact iWave.
2.5.2 eMMC Flash
The RZ/G2UL, RZ/FIVE or RZ/A3UL OSM LGA Module supports 16GB eMMC as default boot and storage device. This is
directly connectedto SD0 controller of the MPU and operates at 1.8V (I/O supply) and 3.3V (NAND core supply) Voltage
levels.
The eMMC flash memory (U2) is physically located on Top side of the Module. The memory size of the eMMC Flash
can be customised based on the requirement by contacting iWave Support Team.
