1.1 Features of SuperH Microcomputer with On-Chip Ethernet
Controller
The SH7616 is a CMOS single-chip microcontroller that integrates a high-speed CPU core using
an original Renesas architecture with supporting functions required for an Ethernet system.
The CPU has a RISC (Reduced Instruction Set Computer) type instruction set. The CPU basically
operates at a rate of one instruction per cycle, offering a great improvement in instruction
execution speed. In addition, the 32-bit internal architecture provides improved data processing
power, and DSP functions have also been enhanced with the implementation of extended Harvard
architecture DSP data bus functions. With this CPU, it has become possible to assemble low-cost,
high-performance/high-functionality systems even for applications such as realtime control, which
could not previously be handled by microcontrollers because of their high-speed processing
requirements. The SH7616 also includes a maximum 4-kbyte cache, for greater CPU processing
power when accessing external memory.
The SH7616 is equipped with a media access controller (MAC) conforming to the IEEE802.3u
standard, and an Ethernet controller that includes a media independent interface (MII) standard
unit, enabling 10/100 Mbps LAN connection. Supporting functions necessary for system
configuration are also provided, including RAM, timers, a serial communication interface with
FIFO (SCIF), interrupt controller (INTC), and I/O ports.
To improve the efficiency of frame transmission/reception, the processing power of the DMAC for
the Ethernet controller is improved and the FIFO for the DMAC has 2 kbytes. A CAM match
signal input function is provided for systems that require multiple MAC addresses. In serial I/O
with three channels, one operates with the FIFO for better data processing power when connected
to the codec.
