C8051F330 controlling power sequencing app note(PDF!) from Silicon Labs. An increasing number of devices such as FPGAs, DSPs, RISC-CPUs, and communications ICs operate at two or more supply voltages. The core logic commonly operates from 1.3 to 2.5 V in order to save power while the I/O supply operates from 3.3 to 5 V to […]

App note: Lithium ion battery charger using C8051F300
Lithium ion battery charger implementation using C8051F300 app note(PDF!) from Silicon Labs. Driven by the need for untethered mobility and ease of use, many systems rely on rechargable batteries as their primary power source. The battery charging circuitry for these systems is typically implemented using a fixed-function IC to control the charging current/voltage profile. The […]
App note: Using the DAC as a function generator
A function generator from an C8051 DAC application note(PDF) from Silicon Labs This document describes how to implement an interrupt driven multifunction generator on C8051 devices using the on-chip digital-to-analog converter (DAC). Four different waveforms expandable to any periodic function defined in a table. – Sine Wave (Table Defined) – Square Wave (Calculated) – Triangle […]
