Seems like your chip is actually a 93C46, the CB probably stands for some chip options. The data sheet is here.

Post as a guest Name. The data sheet is here http: The most significant bit is sent first Clock polarity is type 0 positive Clock phase is type 0 rising edge Arduino init example: I suggest you do further reading on the SPI bus and then on microcontrollers, then datasheeet be able to write and read its memory.
This chip is just a simple memory you can write and read to, but does not contain anything else so you cannot “program” it. Damien 3 Email Required, but never shown.

The manufacturer has application notes on the wiring and protocol for their 93 Series Microwire devices. Also, it does not say how fast I should be turning on and off the pins. Sign up using Facebook.
I studied the data sheet and I figured out which pins do what on the chip, but I have yet to figure out how to read and write to it.
So to start off I am definitely not a Computer Engineer, but I am trying to learn. The chip is a slave, passive component and you need a microcontroller to communicate with it.
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.

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.
I am trying to read and write its content using an Arduino, and or a Raspberry Pi, whichever works I just need it to work. Kevin Duarte 1 The manufacturer has application notes on the wiring and protocol for their 93 Series Microwire devices http: Sign up or log in Sign up using Google.
