A Δ E - E telescope exploiting a single silicon chip for both Δ E measurement and scintillation light collection has been tested. It is a Si - CsI (Tl) telescope tailored for mass identification of light charged particles and intermediate mass fragments. A procedure based on two different shaping filters allows for extraction of the Δ E - E information from the single silicon signal. The quality of the obtained fragment identification is expressed in terms of a figure of merit and compared to that of a standard Δ E - E telescope. The presented configuration could be a good candidate for the basic cell of a large solid angle array of Δ E - E telescopes, given the reduction in complexity and cost of the front-end electronics.
