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.
