The STM32F103RET7: 51 I/O lines in a 64-LQFP package give you enough pins to drive a parallel LCD, read a row of sensors, and still have a few spare for panel buttons. The integrated CAN 2.0B controller and USB 2.0 full-speed device interface reduce external transceiver count on the board.
Listed as Active by STMicroelectronics with ROHS3 compliance.
Code written for the C8T6 will run on the RET7 with more memory headroom, but the pinout differs (64-LQFP vs 48-LQFP) so a board redesign is needed.
