Texas Instruments AM1806 / AM1808 Arm®-Based ARM9™ MPUs
Texas Instruments AM1806 and AM1808 Arm®-Based ARM9™ Microprocessors are low-power application processors that allow the designer to quickly develop designs featuring robust operating systems support, rich user interfaces, and high processing performance life. TI AM1806 and AM1808 Arm-Based MPUs feature an ARM926EJ-S 32-bit RISC processor core that performs 32- or 16-bit instructions and 32-, 16-, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously. The peripheral set of the TI AM1808 includes a 10/100Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module.
It also has a SATA controller that provides a high-speed interface to mass data storage devices. The SATA controller supports both SATA I (1.5Gbps) and SATA II (3Gbps). AM1806 and AM1808 MPUs both include a USB 2.0 OTG interface, two I²C bus interfaces, one multichannel audio serial port (McASP) with 16 serializers and FIFO buffers, and more. These TI Arm-Based ARM9 MPUs also provide a Universal Parallel Port that provides a high-speed interface to many types of data converters, FPGAs, or other parallel devices. A Video Port Interface (VPIF) is also included.
