• On-chip ROM capacity

Program ROM : 48K/40K/32K/28K/24K/20K/16K-bytes

CGROM : 16K-bytes

• On-chip RAM capacity : 640/512-bytes

• OSD RAM : 176 × 9-bits

• On-screen display controller

• Four channels × 6-bit AD Converter

• Three channels × 7-bit PWM

• Two channels × 16-bit timer/counter, 14-bit base timer

• IIC-bus compliant serial interface circuit (Multi-master type)

• ROM correction function

• 13-source 8-vectored interrupt system
