Overview
Ordering number : EN5606 CMOS LSI LC75725E 1/4 to 1/11 Duty Dynamic Drive VFD Driver Overview The LC75725E is a 1/4 to 1/11 duty dynamic drive VFD driver.
It provides 43 segment outputs and 11 digit outputs.
It facilitates the construction of display systems operating under the control of a controller.
Package Dimensions unit: mm 3159-QFP64E [LC75725E] Features • Dynamic drive display technique to display four to eleven digits on the VFD.
• Serial data input supports CCB* format communication with the system controller.
• The dimmer level is controlled by serial data input.
(The dimmer has a resolution of 10 bits.
) • High generality since display data is displayed without the intervention of a decoder.
• All segments can be turned off with the BLK pin.
• CR oscillator circuit.
SANYO: QIP64E • CCB is a trademark of SANYO ELECTRIC CO.
, LTD.
• CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
