NPA-201-EV

NPA 201-EV One of the Worlds Smallest 2 I C Pressure Sensor Evaluation Board (0.4 x 0.29) Description 2 The NPA 201-EV is a small and easy-to-use I C Pressure Sensor evaluation board measuring 0.4x0.29 and has standard 0.1in/2.54mm headers for easy use with a bread-board and is small enough to put right into an application. It is based on the Nova Sensor NPA 201 which comes in a 2.0x2.5x1.0 HCLGA style pack- age. The NPA 201 can measure 260-1260 mBar absolute pressure range with 16bits of Resolution. Tem- perature measurement is also included. The NPA is operational from 3.14 to 3.46V and can operate across a -40C to +85C temperature range. The NPA 201 offers an ULTRA-LOW power SLEEP mode of ~20nA Typical and ACTIVE current is 35uA Typical. 2 The NPA 201 utilizes a SIMPLE 3 Command I C interface(Command Request, Read Status, and Read Data). The NPA-201 is already calibrated, so there is no need for REGISTER INITIALIZATION needed. Upon Power Up the NPA 201 is ready to go as it is initialized internally. The NPA 201-EV is compatible with the Embedded Masters Rapid Prototyping Wireless Sensor Kit, EMSENSR-WSP (Wireless Sensor Plugin) and EMRF-WSB (Wireless Sensor Base). The EMSENSR-WSP provides a Sensor Plugin platform that all EMSENSRs can be plugged into. The WSP can be directly con- nected to all of the Silicon Labs EFM32 Starter Kits on one side. The other side allows the EMSENSR- WSB to be connected to provide a BTLE connection using Broadcom based BTLE solutions. www.embeddedmasters.com NPA 201 Full Datasheet link: NPA 201-EV Table of Contents Description .......................................................................................................................... 1 Features ............................................................................................................................... 2 2 I C Commands .................................................................................................................... 3 Schematics ......................................................................................................................... 4 Features 2 Simple 3 Command I C Interface No Hardware Register Initialization VDD Supply Voltage 1.7 to 3.6 VDC 260 1260mBar Absolute Pressure Range Active Current (Typical 3V) = 35uA Sleep Current (Typical 3V) < 20nA Typ On-board 16bit Temperature Sensor: <0.003K/LSB 2ms Wake-up Time to Active Analog Operation Fully Calibrated and Compensated 2 Up to 3.4MHz I C Operation Internal 18bit DSP Running Correction Algorithm 0.4in x 0.29in Breakout Board with .1in/2.54mm Header Spacing that Can be Directly Soldered into a Prototype or Used with Breadboard.
