Product Overview

The AT91SAM9G20B-CU is a SMART Embedded Microprocessor unit 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. 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 400MHz on the ARM core and 133MHz on the system bus and EBI.
