What are you trying to do? LDmicro supports the micro's internal flash (with a PERSIST instruction), and you could implement an RTC in pure ladder,

DS1307 RTC works with I2C bus.

You can use it with your ATMega32 in ldmicro via external C libraries for I2C. Look in LIBRARIES_FOR folder and read HowTo file.

SD Card can work in SPI mode. Look at SPI libraries in the same folder.
