Overview
Description
The SH7729R Group is supported only for the customers who have already adopted these products. Not recommended for new designs. Please use other SuperH Family products instead. & The SH7729R microprocessor incorporates the 32-bit SH3-DSP CPU. & The SH7729R's on-chip peripheral functions include a cache memory, internal X/Y memory, an interrupt controller, timers, three serial communication interfaces, a real time clock (RTC), memory management unit (MMU), a user break controller (UBC), a bus state controller (BSC), and I/O ports, making it ideal for use as a microcomputer in electronic devices that require high speed together with low power consumption.

(SH7729R) What is coherency?
Coherency means that data is matched between cache and external memory. For example, writing to external RAM is not performed if the cache is hit when the cache is used in write back mode. Unmatching of data between the cache and external RAM occurs because only writing to relevant entry ...

(SH7729R) Are there any precautions regarding cache control register setting?
Access to CCR must be performed from H'FFFFFFEC by longword size. CCR modifications must only be made by a program in the non-cached P2 area.

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 ...
