Description
The SAM9G20 embedded microprocessor unit is based on the integration of an Arm926EJ-S
™
processor with fast ROM
and RAM memories and a wide range of peripherals.
The SAM9G20 embeds an Ethernet MAC, one USB Device Port, and a dual port USB Host controller with on-chip USB
transceivers. It also integrates several standard peripherals, such as the USART, SPI, TWI, Timer Counters, Synchro-
nous Serial Controller, ADC and MultiMedia Card Interface.
The SAM9G20 is architectured on a 6-layer matrix, allowing a maximum internal bandwidth of six 32-bit buses. It also
features an External Bus Interface capable of interfacing with a wide range of memory devices.
The SAM9G20 is an enhancement of the SAM9260 with the same peripheral features. It is pin-to-pin compatible with
the exception of power supply pins. Speed is increased to reach 400 MHz on the Arm core and 133 MHz on the system
bus and EBI.
