Recently I stumbled myself on a fairly old blood sugar test strips canisters. Inside them, I found this what they called "Code Card" which inside, an EEPROM Microchip 93LC46B a 1K Microwire compatible serial EEPROM. I want to salvage them for my Arduino project. Is possible to read/write data to them? and how to determine the capacity? I only see 16 bit word size on the datasheet and 1K on the title.

  • Page 1 of the datasheet: The Microchip Technology Inc. 93XX46A/B/C devices are 1Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). - in what way is that vague? – Majenko Jan 8 '17 at 23:20

    Yes you can use it with Arduino. You just have to read the datasheet. – Majenko Jan 8 '17 at 23:21
  • @Majenko Didn't notice that but thanks – conquistador Jan 9 '17 at 0:06
  • BTW, MicroWire is almost like SPI, but CS is active high not active low. – Majenko Jan 9 '17 at 0:08
