Matrix user forums

I'm using an i2c 1mhz memory.
My microcontroller is a dspic33ep512mu810.
My i2c is channel 2. I am using 2 macros available in the forum I will attach (i2c send, i2c receive). I have data loss at this speed. The i2c channel only works by software and hardware not. In the macro i2c transmits I had to put a delay of 5 ms to be able to work.
Can anybody help me?
Thankful;
Ricardo.

What memory device are you using?

LeighM Hello;

Sorry for the delay in answering.
I've been looking at the data sheet.
The memory is an EEPROM 512KBIT 1MHZ ON SEMICONDUCTOR.
I bought 2 units in the digikey and in both the same thing happens.

Thankful.
Ricardo
