Processor
The SAMA7G5 is a high-performance, ultra-low power Arm
®
Cortex
®
-A7 CPU-based embedded microprocessor
(MPU) running up to 1 GHz, with support for multiple memories such as 16-bit DDR2, DDR3, DDR3L, LPDDR2,
LPDDR3, octal/quad SPI and e.MMC Flash.
The SAMA7G5 integrates complete imaging and audio subsystems with 12-bit parallel and/or MIPI-CSI2 camera
interfaces up to 8 Mpixels at 30 fps, up to four I
2
S data I/Os, one SPDIF transmitter and receiver and a 4-stereo
channel audio sample rate converter.
The device also features a large number of connectivity options with Dual Ethernet (one Gigabit Ethernet and one
10/100 Ethernet), six CAN-FD and three high-speed USB and offers advanced security functions (secure boot,
secure key storage, high-performance crypto accelerators for AES, SHA, RSA and ECC).
Refer to the SAMA7G5 Series data sheet for more information (see
3.2.1
Processor Power Supplies
The power management unit IC (MCP16502) provides all power supplies required by the SAMA7G5 MPU:
• 1.1V for the core power rail (VDDCORE)
• 1.275V for the CPU power rail (VDDCPU)
• 1.35V for the memory power rail (VDDIODDR)
• 3.3V for I/Os, oscillators and digital power rails (VDDIN33, VDDUTMII, VDDIOP0, VDDIOP1, VDDQSPI1,
VDDSDMMC2, etc.)
Decoupling capacitors are placed close to the MPU power pins to stabilize the voltage rails.
