The departments are not separate, but the majors are; that is, the EECS department runs several majors, broadly speaking falling into the categories of a) pure CS, with a a course or two of EE to give the general idea; and b) EECS, two majors (Electrical and Computer Engineering, or Computer Science and Engineering) which offer varying combos of CS and EE. (I may have missed one or two). All of these degree programs require CS61A (the local version of SICP), though the department has switched to a version of the course taught in Python.
