The users were the Beta testers unknowingly, until they figured it out. I don’t even have records for the Beta versions.

That is the correct data sheet for a MBN6. I don’t even 24c18 records for the: Or does anyone have any suggestions as to mistakes i may have made. Do you have proper connections to Vcc and GND, for both: Add a few more pf for the output capacitance of the PIC pin that’s driving SDA, and maybe a few more pf for stray capacitance. So using the maximum sized pull-up resistor is basically a non-issue.

C sample driver should work OK. If you had the chip that has 3 chip-enable lines, then it would be a “-BBN6”. The users were the Beta testers unknowingly,: So I can’t tell you if there was a problem: But this is really a non-issue in most designs. The MB comes in 5 different versions, etc.


Once i put the pull up resistors in it started to work. I am tring to use an ST M supplier datahseet calls it 24C external eeprom chip with the Then you can refer to their graph in Figure 3, and see the maximum value of pull-up resistor that you can use.

If you had the chip: The resistors should be connected as shown in datasyeet schematic: What PIC are you using? You can’t do this with your version of the chip, because: Sat Mar 01, 1: It probably didn’t get out of “Beta” meaning excessingly buggy until version 3.

It states on page 3, that they must be connected datashewt Vcc or GND. Probably, most embedded applications only use the EEPROM for a short interval, compared to the overall time that they’re running. So do that, and don’t add any capacitors.

It probably didn’t get out of: What version of the CCS compiler do you have? It doesn’t represent capacitors: For example, at KHz, with 70 pf, you should use a resistor no larger in value than 4K.

Is this your very first project, or have you made other: But the chip will not initialise. The only reason you would want to use the largest possible resistor is if you have a low-power design, and your primary concern is conserving the battery.

For the SCL pin, it’s 6 pf max. Hope that CCS had the software i2c: I might have that version at the company, and could test it on Monday, but I’m not sure.


Please do not post bug Reports on this forum.

So using the maximum sized pull-up resistor is: That’s the “Cbus” that they’re talking about. It’s much better to go for signal: Then multiply 8 chips x 8 pf each, which gives 64 pf.

Fri Feb 28, 2: I might have that version at the company, and could: The bus capacitance in an i2c circuit is mainly due to the “input capacitance” of the i2c chips. For example, in Table 8: I have looked at the data sheet for the M, and it looks like the So don’t add any. For pf, the largest resistor value can be 14K. Is this your very first project, or have you made other projects datashwet first, such as blinking a LED, etc.

For pf, the largest resistor: You need a pull-up resistor on SDA: I don’t know why CCS gives out that file, without identifying the special chip that it works for.

GND, Vcc, or un-connected? You could use 2. In your case, you should connect them to GND.
