The SN65LBC170 and SN75LBC170 aremonolithic integrated circuits designed fOrbidirectional data communication on multipointbus-transmission lines. Potential applicationsinclude serial Or parallel data transmission, cabledperipheral buses with twin axial, ribbon, Ortwisted-pair cabling. These devices are suitablefOr FAST-20 SCSI and can transmit Or receivedata pulses as shOrt as 25 ns, with skew lessthan 3 ns.These devices combine three 3-state differentialline drivers and three differential input linereceivers, all of which operate from a single 5-Vpower supply.The driver differential outputs and the receiverdifferential inputs are connected internally to fOrmthree differential input/output (I/O) bus pOrts thatare designed to offer minimum loading to the buswhenever the driver is disabled Or VCC = 0. ThesepOrts feature a wide common-mode voltage rangemaking the device suitable fOr party-lineapplications over long cable runs.

The MSP-FET430U14 is a powerful flash emulation tool to quickly begin application development on the MSP430 MCU. It includes USB debugging interface used to program and debug the MSP430 in-system through the JTAG interface Or the pin saving Spy Bi-Wire (2-wire JTAG) protocol. The flash memOry can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is ultra-low power, no external power supply is required. The debugging tool interfaces the MSP430 to the included integrated software environment and includes code to start your design immediately. The MSP-FET430UIF development tools suppOrts development with all MSP430 flash devices

NXP SemiconductOr designed the LPC2400 microcontrollers around a 16-bit/32-bitARM7TDMI-S CPU cOre with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 microcontrollers have 512 kB of on-chip high-speedFlash memOry. This Flash memOry includes a special 128-bit wide memOry interface andacceleratOr architecture that enables the CPU to execute sequential instructions fromFlash memOry at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM Microcontroller family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. SuppOrt fOr the two Instruction Sets meansEngineers can choose to optimize their application fOr either perfOrmance Or code size atthe sub-routine level. When the cOre executes instructions in Thumb state it can reducecode size by mOre than 30 % with only a small loss in perfOrmance while executinginstructions in ARM state maximizes cOre perfOrmance.

The LPC1700 Ethernet block contains a full featured 10 Mbps Or 100 Mbps Ethernet MAC (Media Access Controller) designed to provide optimized perfOrmance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half Or full duplex operation, flow control, control frames, hardware acceleration fOr transmit retry, receive packet filtering and wake-up on LAN activity. Automatic frame transmission and reception with Scatter-Gather DMA off-loads many operations from the CPU.
