描述 Description

The μPD75402A(A) is a CMOS single-chip microcomputer which uses the 75X series architecture. It operates at high speed with a minimum instruction execution time of 0.95 μs. The μPD75P402 is also available for system development evaluation. It contains one-time PROM instead of mask ROM used in the μPD75402A(A).FEATURES
? More reliable than the μPD75402A
? High-speed operation with a minimum instruction execution time of 0.95 μs (when the microcomputer operates at 4.19 MHz)
? Low voltage and low-speed instruction execution time of 15.3 μs (when the microcomputer operates at 4.19 MHz)
? Memory mapping by on-chip peripheral hardware
? NEC standard serial bus interface (SBI)
? 8-bit basic interval timer (watchdog timer applicable)
? Interrupt function
? Three vectored interrupts (one external and two internal interrupts)
? One external test input
? Clock output function (remote controller output applicable)
? Capable of specifying the incorporation of 16 pull-up resistors by softwareAPPLICATIONS
Electronic units for automobiles, and suchlike
