The M30620MCP-XXXGP is 16-BIT CMOS MICROCOMPUTER. A 16-bit CMOS microcomputer refers to a microcomputer architecture that uses 16-bit data processing and employs complementary metal-oxide-semiconductor (CMOS) technology for its integrated circuits. It combines a central processing unit (CPU), memory, input/output (I/O) interfaces, and other peripherals on a single chip.



The M16C/62P Group (M16C/62P, M16C/62PT) of single-chip microcomputers are built using the high performance silicon gate CMOS process using a M16C/60 Series CPU core and are packaged in a 80-pin, 100-pin and 128-pin plastic molded QFP. These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruction efficiency. With 1M bytes of address space, they are capable of executing instructions at high speed. In addition, this microcomputer contains a multiplier and DMAC which combined with fast instruction processing capability, makes it suitable for control of various OA, communication, and industrial equipment which requires highspeed arithmetic/logic operations. 1.1 Applications Audio, cameras, television, home appliance, office/communications/portable/industrial equipment, automobile, etc. Specifications written in thi […]

64F7055F40 PDF – RISC Microcomputer – HD64F7055F40

A RISC (Reduced Instruction Set Computer) microcontroller is a type of microcontroller architecture that emphasizes simplicity and efficiency in instruction execution. In contrast to Complex Instruction Set Computers (CISC), which have a larger and more varied set of instructions, RISC architectures streamline the instruction set to a smaller number of simple and frequently used instructions. This design philosophy aims to improve the overall performance of the microcontroller by allowing instructions to be executed more quickly and efficiently.

The 64F7055F40 is a single-chip RISC microcontroller. ( Automotive ECU Microcontroller IC CPU ).

The CPU has a RISC-type instruction set. Basic instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. In addition, the 32-bit internal architecture enhances data processing power. With this CPU, it has become possible to assemble low-cost, high-performance/high-functionality systems even for applications such as real-time control, which could not previously be handled by microcontrollers because of their high-speed processing requirements.
