I'm looking for modern control protocols, designs and/or components to simplify controlling (and running) a very low power system on a chip safely from mains power. I'm in the USA, and on a hobby budget. Consumer trends here are of interest, but so is the National Electric Code. Surely the world has come a long way since X10.
Has Bluetooth LE (BLE) made the older power-line communications standards old-hat? Are there ways of coupling BLE into the power-line that are considered good practices?
I found the datasheet on the Cypress Semiconductor CY8CPLC10 I was referring to earlier (below). Cypress labels it a Integrated Power-line Modem PHY using 2400 bps FSK. That part number suggests its based on the PSOC-1 (8-bit) 5 generations behind their current 32-bit models. I don't think I care about the 8-bit part if I can treat it as a re-programmed modem.
However, the Digikey listing however has some sort of end-of-life notice link, dated July 2019. But that EOL notice seems to be for a CCS7331P-CAZR from Cirrus Logic. Seems like a different device, can anyone clarify what that means?
Also featured in the datasheet is: "Reference Designs Comply with CENELEC EN50065-1:2001 and FCC Part 15". I know what Part 15 is, but I'm not familiar with CENELEC. Seems to have something to do with the 131.5 KHz to 133.5 KHz band.
==What I've tried == (earlier)
A web power-supply-only web search like AC DC Isolated Power 3.3V uA turns up the sort of component I might use for PS alone. Some quite quite inexpensive while still claiming up to 3kV isolation. It even seems like there are some defacto standard pin-outs for these board mounted power supplies. E.g. ebay "1PC NEW AC DC Isolated Power Board Precision 12V300mA 3W 3.5W" at $1.99 quantity one.
But if I add the PLC part AC DC Isolated Power 3.3V uA with power line communications, the results disappoint me.
The Cypress Semiconductor PSOC 5LP illustrates the class of SOC i'm looking to use as a building block. Its got a pretty wide DC input range, so I'm not even sure if I need a regulated supply.
I'm not tied the PSOC family, but I've found it to be very low-cost prototyping friendly. This sort of device has some impressive programmable analog and digital blocks that might make sense to leverage to keep chip count to a minimum. As I remember, Cypress had a PLC product line some years back, but it seems they are out-of-the-game. None of Cypress's current applications notes seem to make recommendations.
