RDC R8610/R3210/R8611/R3211

General:

The R8610 is a high performance and fully static 32-bit RISC microcontroller with the compatibility of Windows based, Linux and most popular 32-bit RTOS. It also integrates 16KB write direct map L1 cache, PCI rev. 2.1 32-bit bus interface at 33 MHz, SDRAM/ROM/memory controller, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included), Fast Ethernet MAC, FIFO UART, 10/100M MAC and USB2.0 Host within a single 216-pin LQFP package to form a system-on-a-chip (SOC). It provides an ideal solution for the embedded system and communications products (such as thin client, NAT router, home gateway, access point and tablet PC) to bring about desired performance.
