When I run my code in the Termite. Functional address lines allow up to eight devices on the same bus, for up to Kbits address space. 24pc32a last bit of the control byte defines the operation to be performed. For pricing and availability, contact Microchip Local Sales. I have configured and coded the control registers correctly as per the datasheet.

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.


Following the Start condition, the 24XX32A monitors. Application Notes Download All. Dstasheet Microchip Technology Inc.

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.

Sign up using Facebook. I fixed up the code and now it works perfectly – the logic analyzer output looks exactly like the datasheet.

Here is my code below: A control byte is the first byte received following the. The 24XX32A also has a page write capability for up to 32 bytes of data.

You create a loop to send a control byte to datsheet device and then parse the ACK looking for a zero at which point the device is ready to accept a new operation.

I took the liberty to format your code a little more so that it can be read more easily. It is not possible to sequentially read across device boundaries. Here is my code below:. AN – Interfacing I2C?

The upper address bits are transferred first, followed by the Less Significant bits. The 24LC32A will then issue an acknowledge and transmit the 8-bit data word. Email Required, but never shown. Single supply with operation down to 2.
