So to start off I am definitely not a Computer Engineer, but I am trying to learn. I found a couple of 93C46CB3 chips along with some other insignifcant chips in a bag, thanks Dad!
I studied the data sheet and I figured out which pins do what on the chip, but I have yet to figure datasheft how to read and write to it. It says it’s serial but it does not say what baud rate it is. Also, it does not say how fast I should be turning on and off the pins.
Does it use PWM?
If so, how fast? The data sheet is here.
I am trying to read datashret write its content using an Arduino, and or a Raspberry Pi, whichever works I just need it to work. The manufacturer has application notes on the wiring and protocol for their 93 Series Microwire devices. Seems like your chip is actually a 93C46, the CB probably stands for some chip options.
This chip is manufactured by many manufacturer, so you may try to find out which manufacturer to get the particular manufacturer datasheet to be sure there is no differences, even there should not be. This chip is just a simple memory you can write and read to, but does not contain anything else so you cannot “program” it. This chip communicate using a SPI bus Serial peripheral bus which has one clock line, and two data lines.
The chip is a slave, passive component and you need a microcontroller to communicate with it. I suggest you do further reading on the SPI bus and then on microcontrollers, then you’ll be able to write and read its memory.

Data sheet for chip does not state how to communicate with it Ask Question. The data sheet is here http: Kevin Duarte 1 The manufacturer has application notes on the wiring and protocol for their 93 Series Microwire devices http: Supports SPI or Microwire protocols The speed for your chip is stated in the datasheet to have a clock frequency of 3MHz but I would recommend 2MHz as that covers all chips in this series.
