UPD75316B

DATA SHEET MOS INTEGRATED CIRCUIT µPD75312B, 75316B 4-BIT SINGLE-CHIP MICROCOMPUTER The µPD75316B is a 75X Series 4-bit single-chip microcomputer capable of the same data processing as an 8bit microcomputer. It is a low-voltage operation version of the µPD75316 with an on-chip LCD controller/driver. Operation at an ultralow voltage of 2.0 V is possible. An ultra small-sized plastic TQFP (12 x 12 mm) is also provided and it is suitable for small-sized sets that use an LCD panel. A detailed explanation of the functions will be given in the user's manual listed below. It should be read before starting design work. µ PD75308 User's Manual: IEM-1263 FEATURES Ultra-low-voltage operation possible: VDD = 2.0 to 6.0 V Instruction execution time adjustment function Can be driven by two 1.5-V manganese batteries.
