General Description
MN55720 General Description
The MN55720 is a high-quality character generator IC that rapidly generates multilevel grayscale data from outline (path) data for characters and similar images. This IC includes input and output FIFO memory units to assure highspeed processing, and provides a local interface (16 or 32 bits) to allow the use of this IC in a wide range of equipment.

2. Type HL4 pins: IRQ and CLOCK
Type HL8 pins: D0 to D31
3. The absolute maximum ratings are limit values for stresses applied to the chip so that the chip will not be destroyed.
Operation is not guaranteed within these ranges.
4. All the VDD and VSS pins must be connected to the external corresponding power supply or ground.
