I fixed up the code and now it works perfectly – the logic analyzer output looks exactly like the datasheet. Community Forum Software by IP. In Production View Datasheet Features: Thanks CW2, I have 4.

The next three bits of the 24lc32 byte. The device is organized as a single block of 4K x 8-bit memory with a 2-wire serial interface. Verilog Model – 24xx32A Devices. This terminates the write operation, but not before the internal address pointer is set.

24LC32A – Memory – Memory

Several functions may not work. When I run my code in the Termite. I totally misunderstood what that address was – I thought it was the device address. Javascript Disabled Detected You currently have javascript disabled.

I2C + Serial EEPROM (24LC32A)

The upper address bits are transferred first, followed by the Less Significant bits. Single supply with operation down to 2. Designers of Serial EEPROM applications can enjoy the increased productivity, reduced time to market and vatasheet design that only a well thought out development system can provide.


Stack Overflow works best with JavaScript enabled. In this case, software can use A0 of the con- trol byte as address bit A12; A1 as address bit A13; and A2 as address bit A Datasehet create a loop to send a control byte to the device and then parse the ACK looking for a zero at which point the device is ready to accept a new operation.

Many thanks for your help – I still have a lot to learn but getting great help like this is always appreciated! Please re-enable javascript to access full functionality.

Remember me This is not recommended for shared computers. The relevant information from the datasheet is as follows: I’ve forgotten my password. Only show products with samples.

The last bit of the control byte defines the operation to. The Chip Select bits in the control byte must. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The control byte consists of a four-bit control code.

Start condition from the master device Figure So the thing is that the writing of the data is not taking place. Could you please share the logic analyzer output? Thank You m00am, i am sorry for the messy and unformatted code dataeheet I am not much of a coder.

Sign up using Email and Password. In this case, software can use A0 of the con. STOP The problem is the highlighted start signal in the middle of the sequence – there’s no preceding stop so I have datadheet be able to generate a start signal in the middle of the control sequence transaction. It’s easy, but it requires a minimal effort. The last bit of the control byte defines the operation to be performed. Please contact sales office if device weight is not available.

Buy from the Microchip Store. The ‘Random Read Sequence’ which allows a byte to be read from a specified address requires a control sequence that includes a start signal high to low transition on the SDA line while SCL is high in the middle like this: Here is my code below:.

I also rephrased dataxheet question so that is is easier to read.
