Ganymed SoC

Overview

The Ganymed® SoC is an embedded multicore RISC-V SoC with outstanding performance and level of security. The SoC design includes nine processing core, divided into a Data Acquisition Unit (DAQU) with one core and a Data Processing Unit (DPU) with eight cores. The RV32 based processor architecture distinguishes into different privileged operating modes to allow real Trusted Platform Computing into the edge. Sensry provides a Zephyr® RTOS based board support package for fast solution integration. Also, we offer embedded programming services to support the final application.

Power

Four different power domains and one reference voltage are required for the Ganymed® system.

Power domain	Value
Core Voltage	0.8 V
I/O Voltage	1.8 V / 3.3 V
MRAM ref voltage	0.6 V
Analog Subsystem	0.8 V / 1.8 V
max. Power dissipation	< 1 W

Clocks

The CPU clock frequency can be set exclusively by the DAQU CPU core. All DPU cores operate at the same clock frequency (unless disabled), while the DAQU core frequency may be different.

Clock domain	Value
Low power operation clock/boot clock	32.768 MHz
System reference clock	25 MHz
System clocks (internal)	Generated from external clock via PLL,as required for functional units
CPU Clock	max. 500 MHz

All the internal clocks are derived from a single PLL operating at a VCO clock source of 2 GHz generated from an extern reference clock of 25MHz. Most of the internal clock dividers are configurable. The DAQU and the peripheral logic can be multiplexed into the 25MHz reference clock domain to provide basic functionality if the PLL and clock dividers are uninitialized.

The following table describes the standard boot values for the clock divider:

Clock domain	Default Reset Value
DAQU main SoC Clock	100 MHz
DPU Clock	100 MHz
Peripherals Clock (Including Ethernet)	125 MHz
CAN-FD Clock	80 MHz
MRAM Clock	20 MHz
TRNG sample Clock	100 MHz
High-Speed SAR ADC Clock	500 MHz
Ultralow-Power SAR ADC Clock	2.5 MHz
Delta Sigma ADC Clock	12.5 MHz

Memory architecture

There different types of volatile and non-volatile memories available on the Data Acquisition Unit (DAQU) and the Data Processing Unit (DPU) cluster. The different memories are accessible with depending on privileges.
