2. BRIEF DESCRIPTION
This User's Manual describes the hardware of the TQMaRZG2x as of revision 0100, and refers to some software settings.
A certain TQMaRZG2x derivative does not necessarily provide all features described in this User's Manual.
This User's Manual does also not replace the Renesas CPU Reference Manuals. The information provided in this User's Manual
is only valid in connection with the tailored boot loader, which is preinstalled on the TQMaRZG2x, and the BSP provided by TQ-
Systems ; see also chapter 5.
The TQMaRZG2x is a universal Minimodule based on the Renesas CPUs RZ/G2H, RZ/G2M, or RZ/G2N. These CPUs feature up to
four Cortex
®
-A53 cores, up to four Cortex
®
-A57 cores and one Cortex
®
-R7 core.
The TQMaRZG2x extends the TQ-Systems GmbH product range and offers an outstanding computing performance.
All components required for the correct function of the CPU, like LPDDR4 SDRAM, eMMC, power supply and power management
are integrated on the TQMaRZG2x. All essential CPU pins are routed to the TQMaRZG2x connectors.
There are therefore no restrictions for customers using the TQMaRZG2x with respect to an integrated customised design.
The functionality of the different TQMaRZG2x is mainly determined by the features provided by the respective RZ/G2x derivative.
