IS82C55AZ - 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

IS82C55AZ Frequently Asked Questions (FAQs)

  • The IS82C55AZ can operate at a maximum clock frequency of 24 MHz.
  • The IS82C55AZ has 55 programmable I/O lines, divided into four 8-bit ports (PA, PB, PC, and PD) and three 4-bit ports (PE, PF, and PG).
  • The power consumption of the IS82C55AZ varies depending on the operating frequency and voltage. At 5V and 24 MHz, the typical power consumption is around 30 mA.
  • No, the IS82C55AZ does not have built-in pull-up resistors on the I/O lines. External pull-up resistors are required if the I/O lines are used as inputs.
  • Yes, the IS82C55AZ can be used in a 3.3V system, but the maximum operating frequency is reduced to 12 MHz at 3.3V.
