How to interface the MRF49XA Transceiver to PIC Microcontrollers

How to interface the MRF49XA Transceiver to PIC Microcontrollers

MRF49XA by Microchip is a highly integrated RF transceiver that can be used in the 433, 868 and 915 MHz frequency bands. FSK modulation is internally used by this module.

How to implement DDR2/mDDR PCB Layout on the TMS320DM35x DMSoC

How to implement DDR2/mDDR PCB Layout on the TMS320DM35x DMSoC

This article contains implementation instructions for the DDR2/mDDR interface contained on the TMS320DM35x Digital Media System-on-Chip (DMSoC) device. The approach to specifying interface timing for the DDR2/mDDR interface is quite different than on previous devices.

How to Minimize Voltage Offsets in Precision Amplifiers

How to Minimize Voltage Offsets in Precision Amplifiers

In this article, we'll analyze the source of this offset, and then we'll propose a solution based on integrated resistor networks.

Why some inputs and outputs can be less nearly or slightly more than the power rails?

Railroad-rail-to-rail-flanged-wheels

This article discusses rail-to-rail op amps, and explains why some inputs and outputs can be less than, nearly, or slightly more than the power rails.

Extra Notes for Kirin3 Labs

ColdFire

Freescale offers many documents for its latest connectivity microcontroller Kirin3, MCF52259. I believe most of the people will start to evaluate the labs without reading the documents. I am one of these guys who hate reading documents.

Using Microchip's op amp SPICE macro models

op amp SPICE macro models

The SPICE macro models for Microchip’s operational amplifiers (op amps) aid in the design and analysis of various circuits by allowing for detailed simulation of the circuit being designed.
