The article reads the difference between MSP430 series and 89C5l series

Msp430 series single-chip microcomputer is a new type of 16-bit single-chip microcomputer, its main feature is low power consumption, fast speed, the main development language is c. The development environment has iar integrated development environment.

Msp430 microcontroller has different series, there are f series, c series. For example, the f series msp40f135 indicates that rom is a flash type. The f series 13 series 14 series are commonly used. There are two types of 13 series: msp430f133 and msp430f135. 14 series have msp430f149\msp430f144 and so on.

For example, msp4301f149 has 60KB of flash and 2KB of ram. Compared to 51, it's a big deal.

C51 microcontroller has more representative, such as 64KB of flash and 1KB of ram is very large.

The main difference between the 51 microcontroller and the 430 microcontroller is that 51 is 8-bit and 430 is 16-bit. The development environment has a corresponding c development environment.

The C 51 microcontroller is an 8-bit microcontroller. Its instruction is a complex instruction set called CISC, which has a total of 111 instructions. The MSP430 microcontroller is a 16-bit microcontroller and uses a reduced instruction set (RISC) architecture. There are only 27 simple instructions and a large number of instructions are analog instructions. Numerous registers and on-chip data memory can participate in multiple operations. These kernel instructions are single-cycle instructions, powerful functions, and fast operation.

MSP430 microcontroller ultra-low power consumption, is the lowest of all microcontrollers, mainly used for products with batteries such as electricity meters, meters, portable products. Of course, the price is high, TI's products are good.

C 51 single-chip microcomputer application is too wide, no entry, for applications that are not very demanding. The main reason is that the price advantage is too big. Basically it is below 5RMB.

1, 89C51 one-chip computer is 8 one-chip computers. Its instruction is a complex instruction set called "CISC", which has a total of 111 instructions. The MSP430 microcontroller is a 16-bit microcontroller, using a reduced instruction set (RISC) architecture. There are only 27 simple instructions, and a large number of instructions are analog instructions. Numerous registers and on-chip data memory can participate in multiple operations. These kernel instructions are single-cycle instructions, powerful functions, and fast operation.

2. 89C51 series single-chip microcomputer because its internal bus is 8-bit, its internal functional modules are basically 8-bit. Although after various efforts its internal function module has increased significantly, but by its own structure is very limited, especially The increase in analog features is even more difficult. The basic architecture of the MSP430 series is 16-bit. At the same time, there is an 8-bit bus after conversion of its internal data bus. In addition, the MSP430 series itself is a hybrid structure. Therefore, for an open architecture such as this, it is an extension. The 8-bit function module is also a 16-bit function module, and even a function module such as extended A/D conversion or D/A conversion is convenient. This is the reason why the MSP430 series and its features have rapidly increased.

3, is above the development tools. For the 89C51, since it was the earliest SCM that entered China, people were familiar with it. Together with the efforts of all parties in China, many of the development tools that were suitable for us were created. But how to achieve online programming is still a big problem. For the MSP430 series, due to the introduction of Flash-type program memory and JTAG technology, it not only makes the bursting tools easy, but also has a relatively low price, and it also enables in-circuit programming.

4, 89C5l microcontroller's own power supply voltage is 5 volts, there are two low-power modes: standby mode and power-down mode. Under normal conditions, the current consumption is 24mA. In the power-down state, the current consumption is still 3mA. Even in the power-down mode, the power supply voltage can be reduced to 2V. However, in order to save the data in the internal RAM, it is necessary to provide about 50uA current. The superiority of MSP430 series MCU in low power consumption is unmatched by the 89C5l series. Because of this, the MSP430 is more suitable for use in battery-powered instruments and meters.
