Introduction

The MC9S12DP256BMPV Microcontrollers is a low-cost solution for embedded applications that require large Flash memory, DPRAM (8K) and multiple FlexCAN buses. It has an enhanced Multiply Accumulate Unit and can perform up to 16 operations per clock cycle. This enhances the performance of the MC9S12DP256BMPV significantly as compared to other CPUs.

Application field

The MC9S12DP256BMPV is widely used in a variety of embedded applications, such as automotive, military and aerospace, industrial control, banking and finance, communications, and home appliances. This microcontroller can be used for stimulus for control room applications, for motor control, for motor control with multiple CAN buses, and for communication applications that require multiple CAN buses. This feature provides developers with the flexibility of creating a solution that fits their application’s unique requirements. Additionally, the MC9S12DP256BMPV offers a wide selection of on-chip modules and peripherals, such as a comparative-accuracy A/D converter, flexible CAN interfaces, and a wide range of timing and control capabilities.

Working Principle

The MC9S12DP256BMPV has an on-chip, intensive, 16-bit CISC processor called an S12, along with an optimized 16-bit CISC instruction set. The S12 has flexible data manipulation capabilities such as rotate, shift, bit operations, and look up table (LUT). In addition, it has an enhanced Multiply Accumulate Unit (MACU) that can perform up to 16 operations per clock cycle. This significantly improve performance of the MC9S12DP256BMPV as compared to other CPUs.

The MC9S12DP256BMPV also features an 8K byte DPRAM. The DPRAM helps in memory mapping for dual byte/word and long variables and can be as a work area for DMA transfers and to store program data. It also has a powerful 16-bit CISC processor with advanced interrupt structure and exception support, along with an on-chip, powerful debugging logic. The debugging logic includes a data breakpoint, instruction breakpoint, single-step, and long-addressing modes.

Other peripherals on the MC9S12DP256BMPV include a comparator-accuran, over-voltage and temperature protection unit, flexible CAN interfaces, multiple timestamp/counter with input capture and output compare functions, Capture/Reload registers, internal bus control, and much more. This makes the MC9S12DP256BMPV more versatile and enables developers to create applications that offer higher reliability and performance.
