• Package :
  - 56-pin plastic QFP (QFP56P910-0.652K) (Product name: MSC1200-xxGS-2K/MSC1200V-xxGS-2K) xx indicates the code number.

The MSC1200-xx/1200V-xx is a Bi-CMOS display driver for 1/2-duty vacuum fluorescent display tube. This device consists of a 64-bit shift register, latches, an analog dimming circuit, a digital dimming circuit, a keyscan circuit, and drivers.

The MSC1200-xx interface with a microcomputer can be done only with four signal lines (CS, DATA I/O, CLOCK, and INT). Also, the DATA I/O and CLOCK signal lines can be shared with other peripherals by using the chip select function.

Also available is the MSC1200-01/1200V-01, a model with the general purpose code "-01".

Products MSC1200-xx with custom code are manufactured according to customer orders.
