LC75700T : Ordering number : ENN7632 LC75700T CMOS IC Key Scan IC http://onsemi.com Overview The LC75700T is a key scanning LSI that accepts input from up to 30 keys and can control up to four general purpose output ports. Therefore it can reduce the number of lines to the front panel in application systems. Features  Key input function for up to 30 keys.  General-purpose output ports for up to four pins.  A key scan is performed only when a key is pressed, and thus power dissipation is reduced.  Serial data I/O supports CCB format communication with the system controller.  Switching between the key scan output port and general purpose output port functions can be controlled by the control da.

LC75725E : 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 intervent.

LC7573N : 1. Consider the examples shown in Figure 4, where data is set up so that the segment outputs S1 to S19 output a low level on the G1 digit output timing and a high level on the G2 digit output timing. (Here, the G2 side being lighted) 2. The digit output G1 and G2 waveforms in Example 1 are output when the 10 bits of dimmer data (DM0 to DM9) are set to 3FEH. The relation between t1 and the oscillator frequency fOSC is: t1 = 2/fOSC. For example, if fOSC = 1.6 [MHz], then t1 = 2/1.6 [MHz] = 1.25 [µs]. Note that t1 and t2 are the same period in Example 1. 3. The digit output G1 and G2 waveforms in Example 2 are those when the dimmer data (DM0 to DM9) are set to a smaller value. Although the tim.
