MSP430G2231: I2C constant drain

Dallin Lloyd
Prodigy 160 points

Part Number: MSP430G2231

I am configuring a MSP430g2231 device to read data. I am then using the built in I2C interface to store data on EEPROM.

I understand that i need pullup resistors on the I2C bus. However my question is:

Will the pull-up resistors on the I2C bus be a constant power drain? or a drain only when sending / receiving data? This is a power storage sensitive application.

Thank you.
