1. Description
The SAM9260 is based on the integration of an ARM926EJ-S processor with fast ROM and RAM memories and a wide
range of peripherals.
The SAM9260 embeds an Ethernet MAC, one USB Device Port, and a USB Host controller. It also integrates several
standard peripherals, such as the USART, SPI, TWI, Timer Counters, Synchronous Serial Controller, ADC and
MultiMedia Card Interface.
The SAM9260 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.
2. SAM9260 Block Diagram
The block diagram shows all the features for the 217-LFBGA package. Some functions are not accessible in the 208-pin
PQFP package and the unavailable pins are highlighted in “Multiplexing on PIO Controller A” on page 31, “Multiplexing
on PIO Controller B” on page 32, “Multiplexing on PIO Controller C” on page 33. The USB Host Port B is not available in
the 208-pin package. Table 2-1 on page 2 defines all the multiplexed and not multiplexed pins not available in the 208-
PQFP package.
