• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Chapter 1. Product Overview
1.1 INTRODUCTION
The ADM00805 Evaluation Board for PAC1934 provides a flexible platform for evaluating PAC1934 and demonstrating the features of the PAC1934. A PAC1934 device in
a wafer level chip scale package (WLCSP) is mounted to the board.
The ADM00805 has a USB connector to connect to a computer for device communication. The PAC1934 device may be powered directly by V
or by an external connection for V

I
C communication can be provided over USB using the on-board MCP2221 USB to
2
I
C Bridge. There is also a header that facilitates direct I2C communication by connect-
ing the V
or a Linux system. See Section 4.9 “Direct External I2C Connection” for important
details if using direct I
The shorting shunts and the switch on the board facilitate either simple demonstration
of the device functions using on-board current sources or detailed evaluation of
function and performance with external sources, including prototyping the system.

1.2 PAC1934 DEVICE FEATURES
The PAC1934 is a four-channel DC power/energy monitor with accumulator. There is
a16-bit ADC for monitoring power rail voltages connected by a multiplexer to the positive (+) input pin of each channel, producing results named V
16-bit ADC for measuring the voltage across a current sense resistor. This ADC is connected by a differential multiplexer to the +input and –input pins for each channel, producing results called V
sequential fashion to scan all four channels up to 1024 samples per second (sps).
The device also computes V
these power results in an Accumulator. The device registers also hold eight times averaged V
surements. All the results are stored in registers. The values in the Results Registers
only change when a REFRESH or a REFRESH_V command is sent. Software applications are available for plotting, displaying and logging data. These applications also
calculate energy based on the accumulated power and accumulation time.

The ADM00805 Evaluation Board has a PAC1934 device mounted on the board and
enables direct control of all device pins and easy measurements of on-board or external voltages and currents. The I
a shunt gives 0x22. Other addresses are possible by replacing R22 with a new value.
Sampling rate is 1024 sps by default, due to the shorting shunt on the SLOW pin connector (J23) tying the SLOW pin to ground. Remove this shunt for the SLOW sampling
rate of 8 sps.
