MCP3909 3-Phase Energy Meter Reference Design
(MCP3909RD-3PH1)
This reference design is a fully functional 3-phase
energy meter including PC software used for automated
calibration. The reference design consists of two boards:
the main metering board with the MCP3909 devices and
PIC18F2520 that performs the power calculations, and the
USB interface module which uses the PIC18F4550. The
meter design contains serially accessible registers and is
intended to be flexible and upgraded with a variety of PIC
microcontrollers using the included firmware.

MCP23X17 16-bit GPIO Expander Evaluation Board
(MCP23X17EV)
This board demonstrates the simple
input/output functionality of the
MCP23017 (I2C interface) and the
MCP23S17 (SPI interface). The
system demonstrates the simplicity of
monitoring four pins configured as inputs and applying a
predetermined pattern on LEDs connected to the remaining
12 pins configured as outputs.

MCP215X/40 Developer’s Daughter Board
(MCP215X/40EV-DB)
This daughter board evaluates and demonstrates the
MCP2150, MCP2155 or the MCP2140 IrDA Standard
Protocol Handler with Encoder/Decoder devices. Headers
allow the MCP215X/40 Developer’s daughter board to be
easily jumpered into systems for development purposes.
This board also interfaces with the PICDEM HPC Explorer,
PICDEM FS USB and PICDEM LCD demo boards.

MCP6V01 Thermocouple Auto-Zeroed Reference
Design Board (MCP6V01RD-TCPL)
The MCP6V01 design board
demonstrates how to use a difference
amplifier system to measure
Electromotive Force (EMF) voltage at the
cold junction of thermocouple in order
to accurately measure temperature of the thermocouple
bead. This can be done by using the MCP6V01 auto-
zeroed op amp because of its ultra low offset Voltage (VOS)
and high Common Mode Rejection Ratio (CMRR).

MCP651 Input Offset Evaluation Board (MCP651EV-VOS)
This evaluation board provides a simple means to measure the
boards op amp input offset voltage under a variety of operating
conditions. The measured input offset voltage (VOST) includes
the input offset voltage specified in the data sheet (VOS) plus
changes due to: power supply voltage (PSRR), common mode
voltage (CMRR), output voltage (AOL), input offset voltage drift
over temperature (ΔVOS/ΔTA) and 1/f noise.
MCP6V01 Input Offset Demo Board (MCP6V01DM-VOS)
This demo board provides a simple means to measure the
MCP6V01/2/3 op amps input offset voltage under a variety
of bias conditions. This VOS includes the specifi ed input offset
voltage value found in the data sheet plus changes due to
power supply voltage, common mode voltage, output voltage
and temperature.
Power Management
MCP1640 Synchronous Boost Converter Evaluation
Board (MCP1640EV-SBC)
This board uses the MCP1640 in a high-efficiency
(up to 96%), fixed frequency (500 MHz), step-up
DC-DC converter. It demonstrates a minimum
number of external component power supply
solutions for applications powered by alkaline,
NiCd/NiMH or one-cell Li-Ion or Li-Polymer batteries.
MCP1630 Boost Mode LED Driver Demo Board
(MCP1630DM-LED2)
This demo board is a step-up, switch-mode, DC-DC converter
used for power LED applications. The demo board provides
a 350 mA or 700 mA constant current source with a jumper
selection. The input operating voltage range is 9-16V DC and
the board can supply up to 30W to a string of power LEDs.
MCP1631HV Multi-Chemistry Battery Charger
Reference Design (MCP1631RD-MCC2)
This reference design board is used to charge one to fi ve NiMH
or NiCd batteries, charge one or two cell Li-Ion batteries, or
drive one or two 1W LEDs. The board uses the MCP1631HV
high speed analog PWM and PIC16F833 to generate the charge
algorithm for NiMH, NiCd or Li-Ion batteries.
Thermal Management
TC1047A Temp-to-Voltage Converter PICtail™
Demo Board (TC1047ADM-PICTL)
This board demonstrates how to interface the
TC1047A device to a MCU. Connects directly to
the PICkit 3 Starter Kit, providing a platform for
code development and evaluation. Demonstrates
a good example of how to integrate an analog
temperature sensor into a system.
MCP9700 Thermistor Demo Board (MCP9700DM-TH1)
This demo board contains analog circuitry to measure
temperature. The board uses BC Components’ 232264055103
NTC thermistor to convert temperature to resistance. The
thermistor is placed in a voltage divider which converts
resistance to voltage. This voltage is filtered and placed at the
MCP6S22 Programmable Gain Amplifier’s (PGA) CH0 input. The
PGA gains and buffers the thermistor.
