No, the president is not mandated to have a cabinet. It would not be advisable for a president to go without a cabinet because they act to help the president make educated decision on policies. The Constitution does not mention anything about the president's cabinet.

unwritten constitution
No. Article I deals with Congress, so I assume you are referring to Article II, which is still "No." The Presidential Cabinet is completely outside the descriptions of the Executive as provided by the Constitution. President Washington wanted to bring advisers into the Presidency with him to oversee certain matters and they would discuss policy decisions in the Kitchen (whence the term "Cabinet" comes). The decision to have such advisers was lauded by other politicians and the practice has become a cemented part of the system even if it is not explicitly provided for by the letter of the Constitution.

The president appoints cabinet members with senate approval.
