SH7670: Embedded Processors with Ethernet MAC and High-speed USB 2.0 Host

Delivering the performance, integration and connectivity needed for

home networking, office automation and industrial networking applications

The MPUs in the SH7670 series have a 200MHz SH-2A 32-bit CPU core with FPU and integrate an Ethernet MAC, USB high-speed host/function

controller and many other peripheral functions. They deliver the high-speed instruction execution, low-power operation, and built-in functional-

ity needed for creating advanced designs for applications such as network hubs and gateways, security and DRM license-management functions,

NAS equipment, digital A/V products and multi-node industrial control systems, among many others. One standout feature of these devices is the

fast Host Interface (HIF) that enables another system CPU to offload I/O and connectivity functions to the powerful SH7670.

These microprocessors are supported by a comprehensive suite of

system development tools and evaluation boards from Renesas

and partners. For example, the Renesas M3A-HS71G50 board

with Express Logic’s ThreadX

RTOS and networking products

implements a thoroughly proven solution that saves system

development time and cost.

SH7670 Benefits:

왘

Provides HIGH computing power (1.8MIPS/MHz) for handling control

plus signal-processing tasks

왘

Offers high ROM code efficiency so less external memory is needed

왘

Delivers high-throughput connectivity via Ethernet and USB 2.0 ports

for efficient interfacing to systems, subsystems and other chips

왘

Interfaces seamlessly with the main CPU in embedded systems,

offloading it to make more computing bandwidth available for control

and communication functions

왘

Integrates a rich peripheral set that maximizes system performance,

reduces the system BOM, achieves a smaller footprint on the circuit board

왘

Operates with relatively low power consumption and offers power-down modes for optimizing power dissipation according to the tasks being performed, thus

helping to maximize battery life and enabling “green” system designs

왘

Provides comprehensive support tools and products that help shorten system development cycles so products can be moved to market quicker

SH7264 Block Diagram

SH7262/7264: Microcontrollers with 1Mbyte On-Chip SRAM

for Digital Audio and Graphical Dashboard Applications

Supporting a VGA-size TFT-LCD panel without external SDRAM and implementing

most of the electronics of mid-range and low-end systems in a single chip

왘

No external SDRAM needed for a

WQVGA-size TFT-LCD panel display

왘

Extensive peripheral integration for

compact, low-cost system designs

왘

Motor-control PWM timer can control

the display of up to four gauges

왘

Optional SDIO, CAN or IEBus interfaces

facilitate networked applications

The highly integrated 144MHz MPUs in the SH7262 and SH7264 series target mid-range

and low-end consumer, automotive and industrial such as digital audio systems and graphical

dashboards for automobiles. Containing many hardware functions and 1MB of SRAM, they

make it possible to design — mainly with a single chip —products that provide powerful

graphics capabilities or TV display functions. The chips can handle timing, communication,

interface, decompression, display drive, motor control, data conversion, and other tasks.

For system development, an on-chip debugging function and the E10A-USB emulator can be

used. Other support products include the soon to be available Renesas SH7264 Evaluation

Board with VGA TFT-LCD and Express Logic’s ThreadX® RTOS and USBX, FileX

products, as well as Swell Software’s Peg GUI library. Middleware supports compression

standards such as MP3, WMA, and AAC.
