UPD178018A中文资料瑞萨数据手册PDF规格书

The µPD178004A, 178006A, 178016A and 178018A 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.

FEATURES

• Internal high-capacity ROM and RAM

• Instruction Cycle: 0.44 μs(4.5-MHz crystal oscillator used)

• Large array of on-chip peripheral hardware

General-purpose input/output port, 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: 17

• 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)

APPLICATIONS

Car stereo, home stereo systems.
