ACCELEROMETER MMA8652FC:

The MMA8652FC is an intelligent, low-power, three-axis, capacitive micromachined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user-programmable options, configurable to two interrupt pins. Embedded interrupt functions enable overall power savings, by relieving the host processor from continuously polling data. There is access to either low-pass or high-pass filtered data, which minimizes the data analysis required for jolt detection and faster transitions. The device can be configured to generate inertial wake-up interrupt signals from any combination of the configurable embedded functions, enabling the MMA8652FC to monitor inertial events while remaining in a low-power mode during periods of inactivity. The MMA8652FC is available in a small 10-pin DFN package (2 mm x 2 mm x 1 mm).

Features

• 1.95 V to 3.6 V supply voltage
• 1.62 V to 3.6 V digital interface voltage
• ±2 g, ±4 g, and ±8 g dynamically selectable full-scale ranges
• Output Data Rates (ODR) from 1.56 Hz to 800 Hz
• 12-bit digital output
• I2C digital output interface with programmable interrupts
• Four embedded channels of configurable motion detection (Freefall, Motion, Pulse, Transient)
• Orientation (Portrait/Landscape) detection with programmable hysteresis
• Configurable automatic ODR change triggered by the Auto-Wake/Sleep state change
• 32-sample FIFO
• High-Pass Filter Data available per sample and through the FIFO

RS-485 SN75HVD08:

The SN75HVD08 combines a 3-state differential line driver and differential line receiver designed for balanced data transmission and interoperation with ANSI TIA/EIA-485-A and ISO-8482E standard-compliant devices.

The wide supply voltage range and low quiescent current requirements allow the SN75HVD08s to operate from a 5-V power bus in the cable with as much as a 2-V line voltage drop. Busing power in the cable can alleviate the need for isolated power to be generated at each connection of a ground-isolated bus.

The driver differential outputs and receiver differential inputs connect internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus whenever the driver is disabled or not powered. The drivers and receivers have active-high and active-low enables respectively, which can be externally connected together to function as a direction control.

Features

• Operates With a 3-V to 5.5-V Supply
• Consumes Less Than 90-mW Quiescent Power
• Open-Circuit, Short-Circuit, and Idle-Bus Failsafe Receiver
• 1/8th Unit-Load (up to 256 nodes on the bus)
• Bus-Pin ESD Protection Exceeds 16-kV HBM
• Driver Output Voltage Slew-Rate Limited for Optimum Signal Quality at 10 Mbps
• Electrically Compatible With ANSI TIA/EIA-485 Standard

An on-chip 8-bit ADC can adjust charging current automatically based on the output capability of input power supply, so CN3065 is ideally suited for solar powered system. Furthermore, the CN3065 is specifically designed to work within USB power specifications. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature.

The regulation voltage is internally fixed at 4.2V with 1% accuracy, it can also be adjusted with an external resistor. The charge current can be programmed externally with a single resistor. When the input supply is removed, the CN3065 automatically enters a low power sleep mode , dropping the battery drain current to less than 3uA.
