In order 24lcc32a generate the above sequence, call CreateReadTransaction STOP The problem is the highlighted start signal in the middle of the sequence – there’s no preceding stop so I have to be able to generate a start signal in the middle of the control sequence transaction.

You 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.

Here is my code below: These bits are in effect the three Most Significant bits of the word address. Could you please share the logic analyzer output?

I have configured and coded the control registers correctly as per the datasheet. I don’t 24l3c2a how that lets me generate this control sequence: This terminates the write operation, but not before the internal address pointer is set.

Here is my code below:. For the SOT and chip scale packages, the address.

Home – IC Supply – Link. 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: Please contact sales office if device weight is not available.

The Chip Select bits in the control byte must correspond to the logic levels on the corresponding A2, A1 and A0 pins for the device to respond. You currently have javascript disabled. Community Forum Software by IP.

It has been developed for advanced, lowpower applications such as personal communications or data acquisition. The 24LC32A will then issue an acknowledge and transmit the 8-bit data word. The SOT and chip scale packages do not support multiple device addressing on the same bus.

Designers of Serial EEPROM applications can enjoy the increased productivity, reduced time to market and rock-solid design that only a well thought out development system can provide. When set to a zero, a write operation is selected. I took 24lc3a liberty to format your code a little more so that it can be read more easily.

It is not possible to sequentially.
