Overview

PMU IP includes following components: Bandgap reference voltage source, reference current sources and reference frequency generator. Bandgap source forms temperature, power supply and process variations independent voltage.
Reference current sources provide stable output currents which are independent of process/voltage/temperature variations if external resistor is used (CS = “0”) or dependent of process corner and temperature of internal resistor rppd (CS = “1”).
Reference frequency generator could operate in two modes: XTALL mode (OSC_MODE = “0”) and TCXO mode (OSC_MODE = “1”). In XTALL mode external resonator is used, while in TCXO mode external TCXO provides input frequency signal, which is buffered and additionally divided. There are two output frequencies: undivided reference frequency (CLK_REF output) and programmable (OSC_CDiv<7:0>) divided frequency (CLK_REF_DIV). To achieve 50% duty cycle at CLK_REF_DIV output there is additional division-by-two stage embedded in frequency divider, which is turned on by OSC_Div2 = “1”.

A versatile Control Network of power domains in a low power SoC

Developing and verifying a control network in a low-power SoC is a challenging task, especially managing the different states of regulators and modes of power domains. This article first describes state-of-the-art approaches to addressing this issue, and then delves into the solution promoted by Dolphin Integration to go further, thanks to the easy and secure Maestro� solution to manage SoC power mode transitions.

An ESD efficient, Generic Low Power Wake up methodology in an SOC

As the semiconductor industry is moving towards lower technology nodes, more and more complexity is being introduced in the design to beat the competition and provide most innovative solution to cater the needs. One of the biggest challenges that the designer faces is in terms of the keeping the power budgets of the chip within the specification and even innovate to reduce the current numbers. Depending on the application requirements, the designers have to tune up the power profile of the SoC. There are various ways to do so like dynamically changing frequency and voltage of operation, considering system level contributions to power consumption, using various modes of operation etc. In most of the cases, SoC has to support various power modes like Run mode, Sleep mode, Halt mode etc. Different power numbers are defined for each mode. Run modes can further be divided in various sub modes depending on application.
