DATA SHEET
MOS INTEGRATED CIRCUIT
µPD784915A, 784916A
16-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD784915A, 784916A are members of the NEC 78K/IV Series of microcontrollers equipped with a high-
speed 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

• 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-frequency oscillation mode: main system clock frequency = internal clock frequency
• Low-power dissipation mode: CPU can operate with a subsystem clock.
• Supply voltage range: VDD = 2.7 to 5.5 V
• Hardware watch function: watch operation at low voltage (VDD = 2.7 V (MIN.)) and low current
