Its CPU core uses Sun Microsystems' latest Microcontroller and Signal Processor 16-bit microcomputer processor chip, hereinafter referred to as μ'nSP. The 16-bit u'nSP series single-chip microcomputer formed around micro;'nSP, hereinafter referred to as μ'nSP family. It adopts a modular integration structure. It integrates ROMPAM of different sizes and various peripheral components with rich functions centered on the μ'nSP core. The μ'nSP kernel is a generic and structure. In addition to other functional modules are optional structures.

The SPMC65 series single-chip microcomputer is an industrial-grade chip designed for household appliances and industrial control applications; it also has targeted enhanced design for its application fields; for example, strengthening the I/O port to improve the I/O port's driving ability and anti-jamming. Ability to use an enhanced reset system to increase the reliability of the system; to provide reliable and complete CCP functions such as timers/counters.

The SPMC65 family of microcontrollers is a von Neumann architecture; the on-chip program space (ROM) and data space (RAM) are addressed uniformly. Its structure is divided into three parts: kernel, hardware peripherals and special functions. The kernel is the basic part of the chip, such as CPU, CPU registers, etc.; the hardware peripheral is different from the hardware resource configuration parts of the same series of other chips, such as timer/counter, and capture device; the special function can make the system more reliable. , reduce power consumption, such as low voltage reset, power saving mode. SPMC65 series microcontroller structure as shown:

1, home appliances

-Microwave ovens, refrigerators, washing machines, air conditioners, rice cookers, induction cookers, chargers, etc.;

2. Industrial control with I/O control and A/D conversion

In order to facilitate the user's development, Sunplus has also developed a simulation chip ECMC653, which is specifically used for the simulation of SPMC65 series microcontrollers. The ECMC 653 integrates the entire resources of the SPMC65 series microcontrollers with 928 bytes of RAM and 16 kbytes of SRAM. It also integrates a time base, a watchdog timer/counter, six 16-bit timer/counters, and a nine-channel ADC. In order to help users shorten the development cycle and facilitate the detection of hidden errors in the program, a dedicated 1k-byte PCTrace is integrated into the chip to record the running path of the program. Users can learn from the program whether the program is executed correctly.

Currently Sunplus SCM is still widely used. After all, Sunplus has a powerful, efficient instruction system: the instruction format of the μ'nSPTM is compact, fast to execute, and its instruction structure provides support for high-level languages, which can greatly reduce product development time. Low power, low voltage: μ'nSPTM family uses CMOS manufacturing process, while increasing the software to stimulate the weak vibration mode, idle mode and power-down mode, greatly reducing its power consumption, in addition, μ'nSPTM family of operating voltage The range is large, can work normally under the low voltage power supply, and can use the battery to supply power, this has special meaning to its application in field work and other fields.
