UPD75402A数据手册Renesas中文资料规格书

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
