General Description
The EMC1033 is an SMBus temperature sensor that monitors up to three temperature zones and can generate two system interrupts. With ±1°C measurement accuracy, the EMC1033 provides a low-cost solution for critical temperature monitoring applications. Features include automatic resistance error correction and programmable ideality factor configuration eliminating both major sources of temperature measurement error.
The EMC1033 generates two separate interrupts with programmable thermal trip points. The THERM output operates as a thermostat with programmable threshold and hysteresis. The ALERT output can be configured as a maskable SMBus alert with programmable window comparator limits, or as a second THERM output. Both interrupts are maintained in an 8-pin package while a third temperature zone is added with the anti-parallel diode technique. This allows the EMC1033 to be pin compatible with the ADT7461, ADM1032, LM99, and the MAX6649 with the advantage of a third temperature zone.

DESCRIPTION
The MA31755 is a 16 bit Error Detection and Correction Unit intended for use in high integrity systems for monitoring and correcting data values retrieved from memory.
The EDAC placed in the data bus between the processor and the memory to be protected.
Extra check bits added at each memory location are programmed transparently by the EDAC
during a processor write cycle.
The entire checkword and data combination is verified on read cycles.
If any one bit in the incoming data stream is at fault the EDAC can correct the fault transparently, presenting the corrected 16-bit value to the processor.
An error in two bits can be detected but cannot be corrected.
 Both the correctable and uncorrectable error conditions are signalled to the system to allow the processor to take action as required.
Parity is passed through the device unchanged as data bus bit 16.
Tri-statable bus transceivers with a high drive capability are incorporated at the MD and CB busses which allows the usual bus driver devices to be removed and reduces the overall timing overhead imposed on the data bus.
Although designed primarily for MA31750 application, this part may be used in almost any 16-bit processor system requiring high data integrity.

DESCRIPTION
The TLC5942 is a 16-channel, constant current sink driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 128 constant current sink steps for dot correction. dot corrction adjusts the brightness variationsbetween leds. Both grayscale control and dot correction are accessible via separate, dedicated serial interface ports. The maximum current value of all 16 channels can be set by a single external resistor.
