UPD75218 Datasheet 4-bit Microcomputer

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD75218 4-BIT SINGLE-CHIP MICROPUTER The µPD75218 is a microputer 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 µPD75218 has larger ROM and RAM capacity than its predecessor, µPD75217. So several codes required before have been reduced to only one code in the µPD75218 specifications. The one-time PROM product, µPD75P218 and various development tools (IE-75001-R, assembler, etc.) are available for system development evaluation or small production.
