Dual-Output Voltage Regulator (VREG_HIP7A)
22.1
Introduction
The Voltage Regulator provides the internal voltage for the core and logic, which enables devices in the
MAC7200 family to be supplied with a single 5V power supply source.
NOTE
The Voltage regulator on the MAC7200 family of devices does not
implement the VREGEN pin as described in the VREG_3V3 Block Guide.
The Voltage Regulator is enabled by the level on the VDDR pin only.
22.1.1
Overview
Block VREG_HIP7A is a dual output voltage regulator providing the following supplies:
•
1.5V (typ) VDD15
•
3.3V (typ) VDD33
•
3.3V (typ) VDDPLL
The regulator input voltage range is 5V (typ).
22.1.2
Features
The block VREG_HIP7A includes these distinctive features:
•
Two parallel, linear voltage regulators
— Bandgap reference
•
On-chip Voltage Regulators generate all necessary internal supply voltages from 5V only input
voltage, including Flash, Oscillator, PLL and core supply voltage.
•
Bypass mode allows off-chip supply of all on-chip voltages.
•
Power On Reset (POR) and Low Voltage Reset (LVR) detection with independent flags for full
reset source reporting.
22.1.3
Modes of Operation
There are two modes VREG_HIP7A can operate in:
•
Full Performance Mode (FPM)
