CQ82C55AZ - 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

CQ82C55AZ Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the CQ82C55AZ is 4.5V to 5.5V.
  • The CQ82C55AZ 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 2.7V. You can use external resistors and capacitors to adjust the reset timing and threshold.
  • The CQ82C55AZ can operate up to 24 MHz with an external clock source, but the maximum clock frequency may vary depending on the specific application and operating conditions.
  • The WDT in the CQ82C55AZ can be enabled or disabled by software. You can set the WDT timeout period using the WDT control register. The WDT will reset the device if it is not cleared within the timeout period.
  • The internal oscillator in the CQ82C55AZ provides a clock signal for the device when an external clock source is not available. The internal oscillator frequency can be adjusted using the oscillator control register.
