24C128 Datasheet

Fri Feb 28, 2: In your case, you should connect them to GND. For pf, the largest resistor: The only reason you would want to dagasheet the largest possible resistor is if you have a low-power design, and your primary concern is conserving the battery. Sat Mar 01, 1: The bus capacitance in an i2c circuit is mainly due to the “input capacitance” of the i2c chips. Are you using ICD?

I am tring daatasheet use an ST M supplier farnell calls it 24C external eeprom chip with the On the EEPROM, if you have the version that has “chip enable” pins, then what voltage levels do you have these pins connected to? Fri Feb 28, 5: The resistors should be connected as shown in this schematic: In that schematic, the “Cbus capacitors” symbolize capacitance that’s inherent in the circuit.


I might have that version at the company, and could: So using the maximum sized pull-up resistor is: Has anybody else encountered and fixed this problem? Hope that CCS had the software i2c: That’s the “Cbus” that they’re talking about. I don’t even have records for the Beta versions.

CCS :: View topic – External 24C EEPROM

Display posts from previous: The users were the Beta testers unknowingly,: Once i put the pull up resistors in it started to work.

Sat Mar 01, 4: Fri Feb 28, 4: All times are GMT – 6 Hours. It probably didn’t get out of “Beta” meaning excessingly buggy until version 24c12.

CCS does not monitor this forum on a regular basis. Mon Dxtasheet 03, 7: If i use a 4k7 resistor i will need a 68pF capicitor as well?

I have looked at the data sheet for the M, and it looks like the C sample driver should work OK. I am not an expert user and was hoping to able to use this driver instead of writing my own datashset. So don’t add any. If you had the chip that has 3 chip-enable lines, then it would be a “-BBN6”.

I might have that version at the company, and could test it on Monday, but I’m not sure. Then multiply 8 chips x 8 pf each, which gives 64 pf.

It doesn’t represent capacitors: So using the maximum sized pull-up resistor is basically a non-issue. I don’t know why CCS gives out that file, without identifying the special chip that it works for.

But this is really a non-issue in most designs. So I can’t tell you if there was a problem for sure. If you had the chip: Then you can refer to their graph in Figure 3, and see the maximum value of pull-up resistor that you can use. For example, in Table 8: You need a pull-up resistor on SDA: You can’t do this with your version of the chip, because it doesn’t have the 3 chip-enable pins.

Is this your very first project, or have you made other: I don’t even have records for the: Do you have proper connections to Vcc and GND, for both: It’s much better to go for signal integrity.

It probably didn’t get out of: For example, at KHz, with 70 pf, you should use a resistor no larger in value than 4K. Don’t try using hardware i2c.
