CP82C55A - Renesas Electronics

Description: The Intersil 82C55A is a high performance CMOS version of the industry standard 8255A and is manufactured using a self-aligned silicon gate CMOS process (Scaled SAJI IV). It is a general purpose programmable I/O device which may be used with many different microprocessors. There are 24 I/O pins which may be individually programmed in 2 groups of 12 and used in 3 major modes of operation. The high performance and industry standard configuration of the 82C55A make it compatible with the 80C86, 80C88 and other

CP82C55A Frequently Asked Questions (FAQs)

  • The CP82C55A can operate at a maximum clock frequency of 3.5 MHz.
  • The CP82C55A can be configured for I/O operations by setting the appropriate bits in the Port Control Register (PCR) and the Port Output Register (POR).
  • The Ready (RDY) pin is an output pin that indicates when the CP82C55A is ready to accept data from the CPU. It goes low when the chip is busy and high when it is ready to accept data.
  • Interrupts generated by the CP82C55A can be handled by setting the Interrupt Enable (IE) bit in the PCR and configuring the Interrupt Vector Table (IVT) to point to the interrupt service routine.
  • The power consumption of the CP82C55A depends on the operating frequency and voltage. At 3.5 MHz and 5V, the typical power consumption is around 100 mW.
