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.

Hardware Design Support

Title Description
IBIS/BSDL IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.
BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
