One intermediate shale used for parallel interfacing is the Programmable Peripheral Interface (PPI) 8255. This flake is manufactured by Intel Corporation and packaged in the form of a 40 pin dual in line package and designed for a variety of interface functions in the microprocessor. PPI 8255 has 24 I / O pins which are divided into three 8-bit ports. These ports are port A (PA0-PA7), port B (PB0-PB7) and port C (PC0-PC7). As a path for transferring data to and from PPI 8255 an 8 bit data bus channel (D0-D7) is provided. The data bus from this PPI can be connected directly to the data bus from a microcomputer.
DESCRIPTION The LMP90100/LMP90099/LMP90098/LMP90097 are highly integrated, multi-channel, low power 24-bit Sensor AFEs. The devices features a precision, 24-bit Sigma Delta Analog-to-Digital Converter (ADC) with a low-noise programmable gain amplifier and a fully differential high impedance analog input multiplexer. A true continuous background calibration feature allows calibration at all gains and output data rates without interrupting the signal path. The background calibration feature essentially eliminates gain and offset errors across temperature and time, providing measurement accuracy without sacrificing speed and power consumption.
