Introduction
Thank you for choosing the Lattice Semiconductor POWR1014A Breakout Board Evaluation Kit!
Lattice Semiconductors Power Manager II ispPAC -POWR1014A device simplifies power supply design by inte-
grating the analog and digital functions of power supply management (sequencing, monitoring, measuring, and
reset generation) into a single device. This device provides designers with a rich set of features: precision compar-

ators with a built-in voltage reference, 10-bit ADC for I C monitoring, MOSFET drivers and a programmable logic
device (PLD) for sequencing and supervisory logic functions or reset control. Configuration for all subsystems in

the POWR1014A device is stored in non-volatile E CMOS memory. Programming is performed via a USB cable.
Along with the board and accessories, this kit includes a pre-loaded demonstration design. The on-board
POWR1014A device can easily be reprogrammed for customized designs.
Note: Static electricity can severely shorten the lifespan of electronic components. See the Storage and Handling
section of this document for handling and storage tips.
Features
The ispPAC-POWR1014A Breakout Board Evaluation Kit includes:
ispPAC-POWR1014A Breakout Board The board is a 3 x 3 form factor that features the following on-board
components and circuits:
ispPAC-POWR1014A-02TN48I Power Manager II device
USB mini-B connector for power and programming
Nine LEDs
4x15 prototype area
Two 2x20 expansion header landings for general I/O, JTAG, and external power
1x8 expansion header landing for JTAG
3.3V supply rail
Pre-loaded Demo The kit includes a pre-loaded counter design that highlights the use of the embedded
POWR1014A oscillator and programmable I/Os configured for LED drive.
USB Connector Cable The board is powered from the USB mini-B socket when connected to a host PC. The
USB channel also provides a programming interface to the POWR1014A JTAG port.

tions of the POWR1014A Breakout Board, and a complete set of schematics.
Input/Output
Connectors are provided for key functions and test points on this evaluation board, as shown in Figure 1. The USB
programming cable is connected to the USB port (J2) shown on the bottom of the figure.
Access to the ispPOWR1014A devices I/O pins are available as shown along the right and left edges of the
assembly, where two 2x20 blocks of pads (J3 and J6) support the attachment of test probes or a ribbon-cable con-
nector. An array of 60 prototype holes for interfacing is shown at the top of the figure.
Several LEDs on the evaluation board are provided to indicate proper function and as aids to debugging. The green
LED (D9) indicates that the on-board 3.3V supply (derived from the input USB voltage) is powered up. Eight red
LEDs (D1 through D8) are provided to demonstrate control of digital outputs OUT7 through OUT14 so that a user
may easily view the progress of Sequence, Monitor, Reset programs run on the evaluation board.
