DESCRIPTION
The µPD784927 and 784928 are members of the NEC 78K/IV Series of microcontrollers equipped with a high-speed, high-performance 16-bit CPU for VCR software servo control.
The µPD784927Y and 784928Y are based on the µPD784928 with the addition of an I2C bus interface compatible with multi-master.
They contain many peripheral hardware units ideal for VCR control, such as a multi-function timer unit (super timer unit) for software servo control and VCR analog circuits.
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 • DFG amplifier • Reel FG comparator (2 channels)
• RECCTL driver (rewritable) • DPG amplifier • CSYNC comparator
• CFG amplifier • DPFG separation circuit (ternary separation circuit)
• Timer unit (super timer unit) for servo control
• Serial interface : 3 channels
• 3-wire serial I/O : 2 channels
• I2C bus interface: 1 channel
• A/D converter: 12 channels (conversion time: 10 µs)
• Low-frequency oscillation mode: main system clock frequency = internal clock frequency
• Low-power consumption 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 consumption
APPLICATION FIELDS
Stationary VCR, video camera, In-TV VCR
