Item Description
Operating clock pulse
generation circuit (CPG)
Generates the clocks from external clock (EXTAL1).
—
Maximum Cortex-A15 clock: 1.5 GHz
—
Maximum AXI-bus clock: 260 MHz
—
Maximum SDRAM bus clock: 800 MHz (DDR3L-1600), 666 MHz (DDR3L-1333)
—
Maximum media clock: 260 MHz
—
Maximum peripheral clock (HP
ϕ
): 130 MHz
System-CPU shut down mode control supported
Module-standby mode supported
Includes module reset registers to control reset operation of individual on-chip
peripheral modules
System controller (SYSC)
Shuts down and restores power to target modules.
Target modules:
—
Cortex-A15 (with independent shutting down of CPUs 0, 1, and SCU+L2$)
*
1
—
3DGE
*
2
Notes: 1. SCU and L2$ are treated as one power-domain. When CPU is working,
SCU+L2$ can't be powered off.
2. Although 3DGE is a target of power-shutdown, version/revision is different
from H1's 3DGE. Please refer to 3DGE's specification.
Reset (RST)
Includes one reset-signal external output port for external modules
Includes Boot Address Register etc.
Pin function controller (PFC)
Setting multiplexed pin functions for LSI pins
Function of the RZ/G1M pin selectable by setting the registers in the PFC module.
Module selection
Enable and disable the functions of RZ/G1M LSI pins to which pin functions from
multiple pin groups are assigned by setting the registers in the PFC module.
Pull-up control for each LSI pin
On/off of the pull-up resistor on each LSI pin can be controlled by setting the registers
in the PFC module.
Control of SDIO functions
SDIO functions, including the driving ability of pins for the SDIF, can be controlled by
setting registers of the PFC.
General-purpose I/O (GPIO)
General-purpose I/O ports: 244
Supports GPIO interrupts.
Thermal sensor (THS/TSC)
Single channel of thermal sensor
Programmable 4 temperature level for the sensor, to indicate the temperature level
Selectable operation (Interrupt/Reset) when the temperature reaches programmed
