Features of the SH7763
This LSI is a single-chip multifunction CMOS microcomputer that integrates the Renesas
Technology original RISC (reduced instruction set computer) CPU core with the peripheral
functions required for a wide range of application systems such as high-speed Ethernet, display,
and digital AV systems.
The SH-4A is upwardly compatible with the SH-1, SH-2, SH-3, and SH-4 microcompututers at
the instruction set level. This microprocessor core integrates a cache memory and the MMU.
The CPU of this LSI has a RISC instruction set and basically operates on a one-cycle-per-
instruction basis, which dramatically reduces the instruction execution time. The internal 32-bit
configuration enhances the data processing capability. The CPU of this LSI allows high-
performance, highly-functional systems to be built at lower cost even for applications that require
high speeds which cannot be implemented with conventional microcomputers.
With this LSI, the on-chip DMAC (direct memory access controller) permits high-speed data
transfer and the external memory access support function permits direct connection to various
types of memory device. Furthermore, the LSI also incorporates powerful peripheral functions
which are optimal for system configuration, such as the LCD controller, USB full-speed host
controller, function controller, PCI controller, high-speed asynchronous serial communication
interface, serial interface for a voice/audio codec, A/D converter, and D/A converter.
The LSI has a two-channel gigabit Ethernet controller that includes an IEEE802.3z-compliant
media access controller (MAC) and a gigabit media-independent interface (GMII) standard unit,
which allows implementation of 10/100/1000-Mbps LAN connections. In addition, the inclusion
of the security accelerator allows efficient security control for the data on the network.
The external memory access support function permits direct connection to normal memory, DDR-
SDRAM, and PCMCIA.
Because of the various built-in functions that can be applied to a wide range of fields, use of this
LSI not only enables dramatic cost reduction of user-developed systems, but also enables
downsizing and low power consumption.
