Designed to suit DVD recorders, audio players, printers, sequencers, inverters and air conditioners, the SH7618 (HD6417618BG100) 32-bit SuperH RISC microprocessor from Renesas Technology Corp. incorporates an Ethernet controller and a host interface that facilitates connection to another microprocessor.

With a 1.5V power supply voltage, the SH7618 features a 32-bit SH-2 core that offers processing performance of 130MIPS at an operating frequency of 100MHz. The on-chip Ethernet controller includes an IEEE802.3 compliant Media Access Controller and a Media Independent Interface.

Featuring a 4KB on-chip RAM, the product includes a separate 256-byte FIFO (first-in first-out) memory blocks for transmission and reception and a DMAC specifically for Ethernet controller use that implements a ring buffer system. This enables transmit/receive data to be transferred directly between on-chip memory or external memory and the Ethernet controller.

Consuming 150mW of power, the microprocessor is offered in a 176-pin BGA package that measures 13-by-13mm.
