UPD75512

DATA SHEET MOS INTEGRATED CIRCUIT µPD75512(A) 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75512(A) is a 4-bit single-chip microcomputer which employs 75X series architecture, and its performance is comparable to that of an 8-bit microcomputer. In addition to its high-speed processing capabilities, the µPD75512(A) is also capable of processing data in units of 1, 4, or in 8-bits. With its internally provided A/D converter and serial interface, the µPD75512(A) provides the highest performance in its class. Detailed functions are described in the following user‘s manual. Be sure to read it for designing. µPD75516 User‘s Maual: IEM-5049 FEATURES Higher reliability than µPD75512 Adequate I/O lines: 64 (can be provided with pull-up/pull-down resistors: 47) Built-in 8-bit serial interface: 2-ch NEC standard serial bus interface (SBI) internally provided Built-in 8-bit A/D converter: 8-ch Variable instruction execution time function which is convenient for high-speed operation and power saving · 0.95 µs/1.95 µs/15.3 µs (at 4.19 MHz operation), · 122 µs (at 32.768 kHz operation) Program memory (ROM) size: 12,160 × 8 bits Data memory (RAM) size: 512 × 4 bits High-performance timer function: 4-ch · 8-bit timer/event counter · Watch timer · 8-bit basic interval timer · Timer/pulse generator: Capable of outputting 14-bit PWM Clock operation for reduced power consumption possible (5 µA TYP. at 3 V operation) PROM version (µPD75P516) available APPLICATIONS Sw...
