Overview

Description

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.

FAQs

  1. When activating at 8MHz will the two cases change of power consumption?

    Since the Current consumption is proportional to the operational frequency of whole tip, no significant difference will not be produced by PLL setting.

  2. Can several unused pins be pulled-up or pulled-down with one resistor?

    It is NOT recommended that several unused pins collectively pull-up or pull-down with one resistor. The reason is that excessive current flows to the pins and output element may be destroyed when CPU can be runaway from some causes and the setting of input/output pins are ...

  3. Does pass-through current flow when the midpoint of VCC and GND is in?

    When it is used as an analog input, a pass-through current must not flow even if an input voltage is midpoint potential. However, when it is used as a general input and an input voltage is midpoint potential, a pass-through current flows. In addition, you should be aware ...
