UPD784915A

DATA SHEET µPD784915A, 784916A 16-BIT SINGLE-CHIP MICROCONTROLLERS MOS INTEGRATED CIRCUIT DESCRIPTION The µPD784915A, 784916A are members of the NEC 78K/IV Series of microcontrollers equipped with a highspeed 16-bit CPU and are the successors of the 78K/I Series 8-bit single-chip microcontrollers for VCR software servo control. This series contains many peripheral hardware units ideal for VCR control, such as a multi-function timer unit (super timer unit) suitable for software servo control and VCR analog circuits. A one-time PROM version of the µPD784916A, the µPD78P4916, is also available. The functions of the µPD784916A are described in detail in the following user’s manuals. Be sure to read them before designing. µPD784915 Subseries User’s Manual - Hardware: U10444E 78K/IV Series User’s Manual - Instruction: U10905E FEATURES High instruction execution speed realized by 16-bit CPU core Minimum instruction execution time: 250 ns (with 8-MHz internal clock) High internal memory capacity Part Number ROM 48 Kbytes 62 Kbytes RAM 1280 bytes µPD784915A µPD784916A VCR analog circuits conforming to VHS Standard CTL amplifier RECCTL driver (rewritable) CFG amplifier DFG amplifier DPG comparator DPFG separation circuit (ternary separation circuit) Reel FG comparator (2 channels) CSYNC comparator Timer unit (super timer unit) for servo control Serial interface: 2 channels (3-wire serial I/O) A/D converter: 12 channels (conversion time: 10 µs) Low...
