Introduction
Lattice Semiconductor’s Power Manager II ispPAC®-POWR607 device simplifies power supply design by integrating the analog and digital functions of power supply management (sequencing, monitoring, reset generation into a
single device). This device provides designers with a rich set of features: precision comparators with a built-in voltage reference, MOSFET drivers and a programmable logic device (PLD) for sequencing and supervisory logic
functions or reset control. Configuration for all subsystems in the ispPAC-POWR607 device is stored in non-volatile
E2CMOS® memory. Programming is performed via the industry-standard JTAG IEEE 1149.1 interface.
PAC-POWR607-EV Evaluation Board
The PAC-POWR607-EV evaluation board (Figure 1) allows the designer to quickly configure and evaluate the ispPAC-POWR607 device on a fully assembled printed-circuit board. The board supports a 32-pin QFN package,
pads for user I/O, a JTAG programming cable connector, LEDs and switches. JTAG programming signals can be
generated by using an ispDOWNLOAD® programming cable connected between the evaluation board and a PC’s
parallel (printer) port. Both analog and digital features of the ispPACPOWR607device can be easily configured
using PAC-Designer® software.

Programming Interface
Lattice Semiconductor’s ispDOWNLOAD cable can be used to program the ispPAC-POWR607 device on the evaluation board. This cable plugs into a PC-compatible’s parallel port connector, and includes active buffer circuitry
inside its DB-25 connector housing. The other end of the ispDOWNLOAD cable terminates in an 8-pin 0.100” pitch
header connector, which plugs directly into a mating connector, (J3) provided on the PAC-POWR607-EV evaluation
board.
Important Note: The board must be un-powered when connecting, disconnecting, or reconnecting the ispDOWNLOAD Cable. Always connect the ispDOWNLOAD Cable's GND pin (black wire), before connecting any other JTAG
pins. Failure to follow these procedures can in result in damage to the ispPAC-POWR607 device and render the
board inoperable.

Power Supply Considerations
The ispPAC-POWR607 device operates with analog and digital core power supplies of 3.3V, To simplify evaluation
work, the evaluation board was designed to operate from a single 4.5V to 9V power supply, which may be brought
in through a standard 5mm power plug (J2 - center tip positive). The evaluation board provides a linear regulator to
provide the appropriate operating voltages for the ispPACPOWR607 device, as well as reverse polarity protection.
The kit comes with a battery and cable that plugs into the connector at J2 and provides power with a 9V battery,
see Figure 2. If it is desired to test the current in the power down mode of the ispPAC-POWR607, the link between
pins 3 and 4 of J1 should be cut (please refer to Appendix A). Otherwise, approximately 2mA will be drawn when
the device is in power down mode.
Figure 2. 9V Battery Power Interface
Input/Output Connections
Connectors are provided for key functions and test points on this evaluation board, as shown In Figure 1. The JTAG
programming cable is connected to a header (J3) in the lower right corner of the board.
Access to the ispPAC-POWR607 device’s I/O pins is available along the left edge of the assembly, where a 2x17
block of pads (J1)supports the attachment of test probes or a ribbon-cable connector. In addition, there is an array
of 70 proto-type holes for interfacing.
Two momentary switches, S1 and S2, are provided on the evaluation board. They are connected to IN1_PWRDN
and IN2 respectively. Several LEDs are also provided on the evaluation board to indicate proper function and as
aids to debugging. LED D2 indicates that the on-board 3.3V supply is powered up. LED D3 is connected to the
ispPACPOWR607 device’s TDO line, and will briefly flash when downloading, indicating that download data has
made it to the device. Five LEDs are also provided on digital outputs OUT3 through OUT7 so that a user may easily
view the progress of Sequence, Monitor, Reset programs run on the evaluation board.
Demo Sequence and Reprogramming
This evaluation board is shipped from the factory pre-programmed with the “ispPAC_POWR607_LED_Blinker.PAC”
sequence from PAC-Designer’s library. The IN1_PWRDN button must be depressed in order t bring the ispPACPOWR607 device out of its power down mode. The programmed sequence will cause the LEDs to flash for about
six seconds, and then the device will revert to the power down mode.
In order to reprogram the ispPAC-POWR607, it must be brought out of power down mode. Thus, the IN1_PWRDN
button must be depressed immediately before beginning a download to the device from PAC-Designer or ispVM.

VCC is jumpered to 3.3V at pins 1 and 2 of J1 on the backside
of the board. To measure the device power down current, cut the
jumper trace on the backside of the board and connect an ammenter
between pins 1 and 2. In addition, cut the jumper on the backside
betweeen pins 3 and 4 of J1 to disconnect VCCJ. Replace with jumper
blocks for normal operation.
