DATA SHEET

PD784915B, 784916B

16-BIT SINGLE-CHIP MICROCONTROLLERS

MOS INTEGRATED CIRCUIT

DESCRIPTION

The

PD784915B, 784916B are members of the NEC 78K/IV Series of microcontrollers equipped with a high-

speed 16-bit CPU and are versions with improved electrical characteristics of the

PD784915A, 784916A of the

PD784915 Subseries.

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

PD784916B, the

PD78P4916, is also available.

Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before

designing.

PD784915B

PD784916B

• 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

• 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: V

= 2.7 to 5.5 V

• Hardware watch function: watch operation at low voltage (V

= 2.7 V (MIN.)) and low current

APPLICATIONS
