What is the DLP NIRscan Nano EVM?
Description
Cortex-M4 microprocessor operating at 120 MHz with
integrated 1MB flash, 256K SRAM, and USB 2.0 interface.
Single cell Lithium-Ion or Lithium-Polymer battery charger with
up to 1-A charge current from USB. Battery is charged in four
phases: trickle charge, precharge, constant current, and
constant voltage. In all charge phases, an optional battery pack
thermistor monitors the battery temperature for safe charging.
Single chip Bluetooth 4.1 Low Energy subsystem module with
on-board antenna.
Low power, high accuracy temperature and humidity sensor
with 14-bit resolution.
High-efficiency buck-boost converter in wafer chip scale
package supplies 3.3 V.
High-efficiency step-up converter in microSIP package supplies
5.0 V for analog circuits.
High-efficiency step-down converter in microSIP package
supplies 1.8 V.
Quad reset supervisor
Load switch supplies 1.8 V for Bluetooth circuits.
DLP digital controller for advanced light control. The Tiva
microprocessor in conjunction with the DLPC150 controls
individual DLP2010NIR micromirrors to reflect specific
wavelengths of light to a single point InGaAs detector.
DLP power management integrated circuit that powers the DLP
1.8-V, 10-V, 18-V, and –14-V supplies.
High efficiency step-up converter in microSIP package that
supplies the 5 V for the lamp driver
2-A power amplifier that supplies 280-mA lamp current.
Voltage output, current-shunt monitor that monitors lamp
current.
Very-low-noise 24-bit analog-to-digital converter. Converts the
analog output of the InGaAs detector into a 24-bit digital value.
Low-noise, very-low-drift, precision voltage reference that
provides the 2.5-V reference for the transimpedance amplifier.
Low-noise precision operational amplifier. Used as a
transimpedance amplifier for the InGaAs detector.
High-speed operation amplifier that buffers the 2.5-V reference
voltage of the transimpedance amplifier.
Infrared thermopile sensor that measures ambient and detector
temperature
DLP near-infrared digital micromirror
