The PD75218 is a microcomputer with a CPU capable of 1-, 4-, and 8-bit-wise data processing, ROM, RAM, I/O ports, an FIP controller/driver, a watch timer, a timer/pulse generator capable of outputting 14-bit PWM pulses, a serial interface and a vectored interrupt function integrated on a single chip. It is most suitable for applications which use fluorescent display tubes as display devices and require the timer/ watch function and high-speed interrupt servicing, such as VCR, CD and ECR. It can help to provide the unit with many functions and to decrease performance costs. The PD75218 has larger ROM and RAM capacity than its predecessor, PD75217. So several codes required before have been reduced to only one code in the PD75218 specifications. The one-time PROM product, PD75P218 and various development tools (IE-75001-R, assembler, etc.) are available for system development evaluation or small production. The following manual provides detailed description of the functions of the PD75218. Be sure to read this manual when you design an application system. PD75218 User's Manual: IEU-692
