93C46 MICROCHIP PDF

These devices are usually used to store user configurable parameters and device serial numbers. They use a serial bus interface, which allows them to be packaged in inexpensive 8 pin packages. They are usually specified to retain the data for 10 years and to endure , write operations before failure. They only require a 5 volt power supply some 3V only versions exist too. Because these chips use a serial interface, they can not be read quickly enough to serve as conventional memory.

Totilar 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 miceochip to it. Post as a guest Name. The manufacturer has application notes on 93d46 wiring and protocol for their 93 Series Microwire devices.

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. Damien 3 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. 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.

This chip communicate using a SPI bus Serial peripheral bus which has one clock line, and two data lines. Also, it does not say how fast I should be turning on and off the pins.

If so, how fast? Seems like your chip is actually a 93C46, the CB probably stands for some chip options. Data sheet for chip does not state how to communicate with it Ask Question.
