Depending on the style of antenna, the ground plane may or may not need to be removed at the antenna itself. The digitally controlled oscillator DCO allows wake-up from low-power modes to active mode in less than 6ms. The pin-for-pin and code compatible CC has better spurious response and improved close-in phase noise for adjacent channel performance.
What the picture does not show is how the supporting components should be placed and routed.
TI also continuously works to improve their reference designs. This would allow for the traces to be of equal length and shape.
The MCP combines constant voltage, constant current regulation, cell preconditioning, cell temperature monitoring, advanced safety timers, automatic charge termination, and charge status and fault indication.
The current design has improvements to eliminate harmonic emission as well as variations based on power settings. The following sections will provide descriptions of the more important sections along with pictures showing the recommended and not datssheet ways of configuring them. Although TI’s datasheets are invaluable in incorporating this chip into a particular design, we have still found some issues that are not addressed, particularly related to layout, and have written this article to fill in some of the gaps based on our own experience.
The layer directly below the components should be a solid ground. For more information on the CC microcontroller, the datasheet can be found at TI. Table of Contents 1. We typically pair it with the MSP microcontroller, a decision we made before TI’s acquisition cv1100 Chipcon and which works especially well now that both are manufactured by the same company.
With a multi-layer board, the first inner layer can be a solid plane, which will accomplish this requirement rather easily. Thus, the whole memory can be viewed as consisting of pages, or 1, bytes.
At the present time Augustthree designs have been published for the CC chip, but the first two are no longer recommended. Because the CC packaging has pins on all four sides, it can be difficult to connect things such as power.
The current version for the CC is CC The complete file can be obtained from the worldsens web site. Paperback – pages, 2nd edition November 2, The CC also provides hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio. Hardcover – pages August As with the filter balun section, the ground plane below the trace must be solid up to datasehet antenna. If one inductor is placed so that it has a very short straight trace, the other inductor will not fit in front of its corresponding pin.
The whole memory can be erased using datasheet Bulk Erase instruction, or a sector datashfet a time, using the Sector Erase instruction. For more information on the Daatsheet linear charge management controller, the datasheet can be found at Microchip. When pins are located next to each other and have a capacitor associated with each one, these components must be connected individually. With a two-layer design, it becomes more complicated to achieve a solid ground.
However, the trace widths for the filter balun datasueet itself should be as wide as possible without requiring a resize at the pads of the filter balun components in other words, you should make the traces from the CC to the filter inductors the same width as the CC pads. The design of the filter balun accomplishes three main tasks. The balanced portion of the filter balun is very susceptible to variations between the two sections. For more information on the M25P80 flash memory, the datasheet can be found at ST.
Chapter III. WSN Schematic
Design and layout is an art form, and never more so than when you are designing an RF circuit. This will obviously make the layout a little more complicated, but extra effort will be appreciated when the circuit performs as expected without troubleshooting and modifications to the PCB.
You can spend all this time and money you save here on designing better firmware for the chip and its associated microcontroller – with the versatility available with the CC, this is where the real excitement should be!
Schematic of the WSN board. The current version at the time this article was written is Rev D, dated May 29, Filter Topology One of the key pieces of a datashert using the CC is the filter balun.
This will cause the trace for the second inductor to be longer with more bending. The memory is organized as 16 sectors, each containing pages. However since that is not possible, the next best approach is to minimize the amount of inductance within the trace by making it as wide as possible based on the size of the component pads.
