MSP430 single chip microcomputer application in PTN products

Abstract: the MSP430 single chip microcomputer application in PTN products information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Abstract: PTN is a connection-oriented packet technology as the core, at the same time have the end-to-end business management, hierarchical transmission characteristics for the protection of the OAM and telecommunication level, give priority to with business carrying telecommunication level Ethernet, compatible with TDM, ATM business such as integrated transmission technology. 。 More flow meter manufacturers choose model price quote you are welcome to inquire, here is MSP430 single chip microcomputer application in PTN products article details. PTN is a connection-oriented packet technology as the core, at the same time have the end-to-end business management, hierarchical transmission characteristics for the protection of the OAM and telecommunication level, mainly carrying telecommunication level Ethernet business, compatible with TDM, ATM business such as integrated transmission technology. MSP430 series MCU is Texas instruments ( TI） Started in 1996 to market a 16 ultra-low power consumption of mixed signal based on RISC processor ( MixedSignalPocessor) 。 MSP430 series MCU can not only be used in many traditional single-chip computer application field, such as instruments and meters, automatic control, and consumer products, more suitable for some low power battery products, such as can scale ( Water meter, electric meter, gas meter, etc. ) , handheld devices, intelligent sensors, higher cost and operation performance of intelligent instruments and equipment. PTN is a connection-oriented packet technology as the core, at the same time have the end-to-end business management, hierarchical transmission characteristics for the protection of the OAM and telecommunication level, mainly carrying telecommunication level Ethernet business, compatible with TDM, ATM business such as integrated transmission technology. PTN packet transport network is the world recognized instead of the next generation of SDH transmission technology, 1850 TSS is alcatel-lucent to cope with the trend of the development of the mobile IP business uncertainty and model uncertainty introduced the smooth evolution of end-to-end PTN transport solutions. 1850 TSS series products include access to the core of a series of different capacity equipment, launched in the domestic market is currently the TSS - 3、TSS - 5、TSS - 40岁的TSS - 100年,TSS - And TSS - 160 640/320 of a few products. TSS - 5 position is suitable for mixed TDM/Ethernet access scenario, can be configured to STM - 4 levels of SDH/MSTP and exchange capacity of 5 g telecom level Ethernet/PTN platform, support TDM business simulation access at the same time, very suitable for mobile base station access application scenario. TSS - 5 choose select Texas instruments ( TI） The MSP430 microcontroller ( MSP430F5508） The veneer of as its controller, and main communication. 1, the characteristics of MSP430 MSP430 series MCU is Texas instruments ( TI） Started in 1996 to market a 16 ultra-low power consumption of mixed signal based on RISC processor ( MixedSignalPocessor) 。 MSP430 series MCU can not only be used in many traditional single-chip computer application field, such as instruments and meters, automatic control, and consumer products, more suitable for some low power battery products, such as can scale ( Water meter, electric meter, gas meter, etc. ) , handheld devices, intelligent sensors, higher cost and operation performance of intelligent instruments and equipment. MSP430 series MCU will intelligent peripherals, ease of use, low cost, and industry zui excellent properties such as low power consumption perfect unifies in together, can meet the requirements of various applications. MSP430 series MCU key features include: 1) Ultra-low power consumption ( ULP） System architecture and highly flexible clock can significantly prolong the service life of the battery; 2) Integration of various intelligent peripherals: all kinds of high performance analog and digital peripherals can greatly reduce the workload of the CPU; 3) 16 RISCCPU architecture, simple and easy to use and can realize with the industry ling zui new application code density first; 4) Entire industry development environment, provide complete full set of development tools, and Texas instruments. TSS - Five systems use the micro-controller is MSP430F5508 model, as shown in figure 1. 0 interface, four 16-bit timers, high-performance 10 AD converter, two serial communication USART ( UART, SPI and I2C) Interface, the hardware multiplier, direct data access ( DMA) , real time clock module, a warning capacity 25 MHZ clock, 16 k flash memory, 6 ksram and 47 pin. 2、TSS - The TSS - 5 single controller function 5 system USES Linux embedded real-time operating system, select MSP430F5508 as a general purpose single board controller, all share a single microcontroller firmware version. Microcontroller serial port has two working modes: BSL models and APP. Micro control for BSL mode to download firmware version of microcontrollers, APP pattern is used to work properly. As shown in figure 2, the TSS - APP mode General features include: 5 micro controller and main board communication, storage of veneer resource details ( RI） Can detect the slot number and latch state, control veneer LED lights, monitor the veneer of voltage, current, veneer temperature through the integrated temperature sensor monitoring, through the adc module ( ADC) Collection and reporting veneer alarm.
