Microchip Technology SAM9G20
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, Synchronous Serial Controller, ADC and MultiMedia Card Interface.DESCRIPTION
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.FEATURES
