1 / 48 page ![]() © 1997, 1999 DATA SHEET µPD178002,178003 MOS INTEGRATED CIRCUIT The µPD178002 and 178003 are 8-bit single-chip CMOS microcontrollers that incorporate hardware for digital tuning systems. The CPU uses the 78K/0 architecture, which makes it easy to implement high-speed access to internal memory and control of peripheral hardware. Also, the instructions used are the high-speed 78K/0 instructions, suitable for system control. The peripheral hardware includes an input/output port, 8-bit timer, A/D converter, serial interface, power-on-clear circuits, as well as a pre-scaler for digital tuning, a PLL frequency synthesizer, and a frequency counter. The µPD178P018A, one-time PROM or EPROM versions that can be operated in the same supply voltage range as for the mask ROM versions, and various development tools, are also available. Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before designing. µPD178003 Subseries User’s Manual: U13033E 78K/0 Series User’s Manual — Instructions: U12326E FEATURES • Program memory (ROM) capacity µPD178002: 16 Kbytes µPD178003: 24 Kbytes • Data memory (RAM) capacity: 512 bytes • Instruction cycle: 0.44 µs (4.5 MHz crystal resonator used) • Selected peripheral hardware of the µPD178018A Subseries General-purpose I/O ports, A/D converter, serial interface, timer, frequency counter, power-on-clear circuits. • On-chip hardware for a PLL frequency synthesizer. Dual modulus pre-scaler, programmable divider, phase comparator, charge pump. • Vector interrupt sources: 8 • Supply Voltage: VDD = 4.5 to 5.5 V (during PLL operation) VDD = 3.5 to 5.5 V (during CPU operation, when the system clock is fX/2 or lower) VDD = 4.5 to 5.5 V (during CPU operation, when the system clock is fX) 8-BIT SINGLE-CHIP MICROCONTROLLERS Document No. U12628EJ3V0DS00 (3rd edition) Date Published December 1999 N CP(K) Printed in Japan The mark shows major revised points.
