SH7046, SH7148, SH7101, SH7048, SH7104, SH7106, SH7108

The SH7046 Series single-chip RISC (Reduced Instruction Set Computer) microprocessors integrate a Renesas-original RISC CPU core with peripheral functions required for system configuration.

The SH7046 series CPU has a RISC-type instruction set. Most instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. In addition, the 32-bit internal-bus architecture enhances data processing power. With this CPU, it has become possible to assemble low cost, high performance/high-functioning systems, even for applications that were previously impossible with microprocessors, such as real-time control, which demands high speeds.

In addition, the SH7046 series includes on-chip peripheral functions necessary for system configuration, such as large-capacity ROM and RAM, timers, a serial communication interface (SCI), an A/D converter, an interrupt controller (INTC), and I/O ports.

There are two versions of on-chip ROM: F-ZTAT™ (Flexible Zero Turn Around Time) that includes flash memory, and mask ROM. The flash memory can be programmed with a programmer that supports SH7046 series programming, and can also be programmed and erased by software. This enables LSI chip to be re-programmed at a user-site while mounted on a board.

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.
