CP82C55AZ - 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

CP82C55AZ Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for CP82C55AZ is 4.5V to 5.5V.
  • The CP82C55AZ has a built-in POR and BOR circuit. The POR is triggered when the power supply voltage rises above 3.5V, and the BOR is triggered when the power supply voltage falls below 4.2V. You can use external resistors and capacitors to adjust the POR and BOR thresholds.
  • The maximum clock frequency supported by CP82C55AZ is 24 MHz.
  • The WDT in CP82C55AZ is used to reset the microcontroller in case of a software fault. You can enable the WDT by setting the WDTE bit in the WDT control register. The WDT timeout period can be set to 16ms, 32ms, 64ms, or 128ms using the WDTPS bits.
  • Yes, the CP82C55AZ has built-in noise filters on the digital inputs, and it also has a hysteresis voltage of 0.5V on the digital inputs to improve noise immunity.
