SPCE061A1.2.1 General Description
SPCE061A is the latest addition to Sunplus Technology's SPCE500A series of products. SPCE061A is another 16-bit architecture microcontroller released by Sunplus Technology after SPCE500A of nSP? series products and so on. Unlike the SPCE500A, the SPCE061A has only 32K words of flash memory embedded in it, taking into account the user's need for fewer resources in terms of memory resources as well as the ease of program debugging. The higher processing speed makes it possible for the nSP? nSP? to process complex digital signals very easily and quickly. Therefore, compared with the SPCE500A, the ?' nSP?-centered SPCE061A microcontroller is therefore one of the most economical choices for products in digital speech recognition applications.

1.2.3 Structure Overview
The structure of the SPCE061A is shown in Figure 1.2:1.2.4 Pin Arrangement and Description of the Chip
The SPCE061A is available in two package slices, one with 84 pins in the form of the PLCC84 package; it is arranged as shown in Figure 1.4; and the other is an 80-pin, LQFP80 package. It is arranged as shown in Fig.
In the PLCC84 package, there are 15 free feet, the user uses these 15 free feet suspended. In the LQFP80 package, there are 9 free feet, the user uses these 9 free feet ground. The LQFP80 package pin function is introduced here.
1PFUSE can be connected to 5V, PVIN connected to GND and maintained for more than 1s to melt the internal fuse, after which it will not be able to read and load data to the flash memory.
1.2.5 Characterization
Characterization parameters of the SPCE061A system are shown in Table 1.2.
1.2.6 SPCE061A Minimum System
The wiring of the minimum system is shown in Figure 1.6. The crystal and resonant capacitors are connected to the OSC0 and OSC1 terminals, and the phase-locked loop voltage-controlled oscillator's resistor input, VCP, is ready for operation with the corresponding capacitor and resistor. Other unused power supply and ground terminal connected to the 0.1?F decoupling capacitor to improve anti-jamming ability.
1.2.7 SPCE061A Development Methodology
The development of the SPCE061A is realized through the online debugger PROBE. It is both a programmer (i.e., program burner) and a real-time in-circuit debugger. It can be used to replace the common software tools used in the development process of microcontroller applications - hardware online real-time emulator and program burner. It utilizes the SPCE061A's built-in in-circuit emulator ICE (In-Circuit Emulator) interface and Sunplus's in-circuit serial programming technology.PROBE works under Sunplus's IDE IDE software package, and its 5-core emulation header is directly connected to the corresponding pins of SPCE061A on the target board, and is directly connected to the CPU on the target board. ---The other end of the PROBE is a standard 25-pin printer interface, directly connected to the computer print port to communicate with the host computer in the computer IDE integrated development environment software package to complete the online debugging function. Figure 1.7 is a schematic diagram of the connection between the computer, PROBE, the user's target board, Figure 1.8 is the physical connection diagram.
