Working principle

The STR730FZ2H7 is based on Harvard architecture concept and has a 8-bit CPU core. It is based on 8-bit von Neumann architecture with scale of integration (scale of integration is the ratio between the number of individual transistors used in the design of a semiconductor or integrated circuit, and the number of transistors within an integrated circuit). The device is programmed in C/C++ or assembly language. The instruction set consists of 16-bit instructions for managing the data memory, the control memory, data exchange, status registers, arithmetic and logic operations, and control of the chip I/O.

The device includes a MCU Reset circuit, an on-chip timer, a real time interrupt (RTIOS), an analog comparison unit, an analog input compare unit, a 32-bit timer, a PWM output, and an analog output compare/dead time protection. The core also supports up to eight interrupt vectors, which allow handling up to eight interrupts. On-chip peripherals include USART, SPI, Flash memory, and a debug module.

The chip core is powered by an external Vpp/IPR power source, which allows it to run at a maximum clock frequency of 24MHz. Additionally, an on-chip 4Kbytes of Flash memory allows for both erase and write operations, enabling single step programming of the device. The STR730FZ2H7 also supports several external modes such as DMA, both multi- and single-cycle, as well as direct memory access (DMA).
