POWER, CLOCKS, AND RESETS

3.1

Introduction

This Power, Clocks, and Resets (PCR) chapter identifies all the power supplies, clock sources, and reset inputs to the

chip and defines all the derived power, clock, and reset signals. In addition, this section identifies Power, Clock, and

Reset events that may be used to generate an interrupt event, as well as, the Chip Power Management Features.

No references have been cited for this chapter.

3.3

Interrupts

The Power, Clocks, and Resets logic generates no interrupt events to the Host system.

POWER SOURCES

Table 3-1 lists the pins from which the ECE1200 draws current. These current values are defined in Section 8.3, "Power

Consumption," on page 63.

Timing sequences between these power rails are given in Section 9.5.1, "VTR Sequencing and RESETI# Timing," on

page 70.

3.3V

3.3V I/O Power Supply

This supply is used to power the 3.3V I/O pins.

It is to be connected to the “Always-on” /

“Suspend” / ”S5” supply rails in system. There is

no need to connect it to a deeper power well,

such as the Deep Sleep Well, even if that is what

powers the downstream LPC device(s).

This supply must be on prior to the RESETI# sig-

nal being deasserted (system RSMRST#).

1.8V

1.8V I/O Power Supply

This supply is used to power the 1.8V I/O pins.

It is to be connected to the 1.8V “Always-on” /

“Suspend” / ”S5” supply rails in system. There is

no need to connect it to a deeper power well,

such as the Deep Sleep Well, even if that is what

powers the downstream LPC device(s).

This supply must be on prior to the RESETI# sig-

nal being deasserted (system RSMRST#).
