Overview
Description
The SH7709S microprocessor incorporates the 32-bit SH-3 CPU. & This LSI is built in with a variety of peripheral functions such as cache memory, memory management unit (MMU), interrupt controller, timer, three serial communication interfaces, realtime clock (RTC), use break controller (UBC), bus state controller (BSC) and I/O ports. & This LSI can be used as a microcomputer for devices that require both high speed and low power consumption.

Memory Map for a SH7709S
I have been handled a system that uses a SH7709S processor. Now, Michael Barr in his book "Programmin Embedded Systems in C++" mentions that "(The memory map) is arguably the most important piece of information about the system and should be kept up to date and as part of the ...

SH3 7709A vs. 7709S
Hi! What is the difference between the 7709A rev., and the "S" rev.? I didn't found revision history for this parts on the renesas homepage. Can I use 7709S instead of 7709A? (Need to replace in a robot controller board.) Thank you very much. Best Regards: Tibor

Why does standby current of SH7709S/SH7729R increase if RTC is unused?
SH7709S/SH7729R has a on-chip circuit to decrease the consumption current in the standby mode. This circuit has a mechanism to run by using the clock generated by the RTC and it does not run, when the RTC is unused. So the consumption current in the standby mode ...

Please explain TRST pin treatment (SH7709S, SH7729R, SH7706, SH7727)
In normal mode (ASEMD0 = High), TRST can be pulled up or pulled down.

Is the replacement from SH7709S to SH7729R possible?
SH7729R is the one that the DSP function is added to SH7709S. Since SH7729R has upward compatibility over SH7709S, the replacement from SH7709S to SH7729R is not the problem. However, the power voltage is different in each frequency version of 100MHz/133MHz/167MHz/200MHz, so confirm the ...
