The Z86D990HZ008SC is a single-chip microcontroller typically used in embedded systems applications. This microcontroller integrates a 32-bit core processor and peripherals designed for increased performance, low power consumption and minimal space requirements. It is typically used in applications like power meters, smart home appliances, phase control switching, intelligent access control, industrial control and robotics.

The Z86D990HZ008SC combines a 32-bit CPU core and on-chip peripherals such as a Digital Analogue Converter (DAC), Pulse Width Modulator (PWM), Serial Peripheral Interface (SPI), UART, and I2C, along with up to 8 KBytes of SRAM and two KBytes of EEPROM. The on-chip features provide the features essential for many embedded applications including I/Os, Timers, Counters, 16-bit Watchdog timer, Interrupts, PWM outputs. It also includes a dedicated CAN controller with a maximum of 2 channels, an USB 2.0 Device and Host, USB 2.0 On-The-Go (OTG) Mode and a Special Decoding Logic (SDL) for functions like I2C/SPI/UART.

The Z86D990HZ008SC works on a 3.3-Volt power supply and operates in temperatures ranging from -40C to 85C. It is designed to operate with the Real Time Operating System (RTOS), either a commercial RTOS such as ThreadX or an open source RTOS such as FreeRTOS. The Z86D990HZ008SC supports both binary compatible and assembly compatible processor architectures, allowing multi-threaded applications and direct hardware access. The Z86D990HZ008SC implements 16-bit instructions, allowing more flexibility and higher performance.

The Z86D990HZ008SC is commonly used in embedded system designs, due to its fast processor, low power consumption and minimal space requirements. Most applications will require the microcontroller to perform the following functions:

• Process analog signals through its DAC
• Read digital signals from a variety of sensors or actuators
• Communicate with other devices through serial protocols such as I2C, SPI, and UART
• Control other devices through PWM outputs and digital I/O
• Interface with external memory devices, such as EEPROM or SRAM
• Interface with external buses, such as CAN
• Control power settings, such as standby and sleep modes
• Interface with a USB device or host
• Operate and communicate with other devices in a multi-threaded environment

In order to perform these functions, the microcontroller relies on two main components: the Instruction Set Architecture (ISA) and the associated microcontroller peripherals. The instruction set architecture consists of a set of commands that the microcontroller can utilize to process, transfer, and store data. The instruction set architecture is unique to each microcontroller, so the processor will only understand instructions from its own ISA. Each microcontroller may have different instruction set architecture, so programmers have to understand the capabilities of each microcontroller and write code specific for them.

The microcontroller’s peripherals are the components that handle most of the I/O operations in the system. This includes a variety of digital and analog peripheral devices, such as the Digital Analogue Converter (DAC), Pulse Width Modulator (PWM), Serial Peripheral Interface (SPI), UART, CAN, etc. Each peripheral device is used for a specific purpose and can be configured to support different functions, depending on the application.

In most applications, these peripherals are used to communicate with other devices, either in the embedded system, or with other external devices. For example, when used in an embedded system, the SPI bus may be used to transfer data to and from a temperature sensor, or a UART may be used to communicate with an LCD controller. When used with external devices, each peripheral typically has dedicated pins and software routines for communication, allowing the microcontroller to quickly send and receive data.

The Z86D990HZ008SC is an efficient and reliable microcontroller, suitable for a variety of embedded systems applications. Its 32-bit core processor and integrated peripherals provide increased performance and low power consumption, while its small size makes it ideal for space constrained designs. By combining the instruction set architecture and on-chip peripherals, the Z86D990HZ008SC is able to provide most of the functions necessary for embedded system designs at a low cost.
