The TMS370Cx5x family of single-chip 8-bit microcontrollers provides cost-effective real-time system control through integration of advanced peripheral function modules and various on-chip memory configurations. The TMS370Cx5x family presently consists of twenty-one devices which are grouped into seven main sub-families: the TMS370Cx50, TMS370Cx52, TMS370Cx53, TMS370Cx56, TMS370Cx58, TMS370Cx59, and SE370C75x.
