UPD78C14

DATA SHEET MOS INTEGRATED CIRCUIT µPD78C14(A) 8-BIT SINGLE-CHIP MICROCONTROLLER (WITH A/D CONVERTER) The µPD78C14(A) is a single-chip, CMOS 8-bit microcontroller in which a 16-bit ALU, a ROM, a RAM, an A/D converter, a multifunction timer/event counter, and a serial interface are all integrated. Moreover, a 48-Kbyte external expansion memory (ROM/RAM) can be connected. Since the µPD78C14(A) uses the CMOS construction, its operations are performed with low power consumption. By using the standby function, functions such as data retention are performed with lower power consumption. For details on functions, refer to the User’s Manual listed below. Please read it before starting design work. 87AD series µPD78C18 User’s Manual: IEU-1314 FEATURES High reliability as compared with µPD78C14 159 instructions: 87AD instruction set Multiply and divide instructions, 16-bit arithmetic operation instructions Instruction cycle: 0.8 µs at 15 MHz Internal ROM: 16384 W x 8 Internal RAM: 256 W x 8 Direct addressing to an external memory (ROM/RAM) up to 64 Kbytes Highly accurate 8-bit A/D converter: Eight analog inputs General-purpose serial interface: Asynchronous, synchronous, and I/O interface modes Multifunction 16-bit timer/event counter Two 8-bit timers I/O lines: 44 Interrupt functions: Three external, eight internal Non-maskable interrupt: 1 Maskable interrupts: 10 Zero-cross detection function (two inputs) Standby functions: HALT mode, Hardware/software STOP mode ORDERING INFO...
