CMP82C55AZ - Renesas Electronics

Description: The Renesas 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). The MX82C55A has identical features as the X82C55 with the exception of no bus hold devices on the port pins. 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 two groups of 12 and used in three major modes of operation. The hi

CMP82C55AZ Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the CMP82C55AZ is 4.5V to 5.5V.
  • The chip select signal (CS) is active low, and it should be connected to a logic low level to enable the device. The CS signal should be tied to VCC or a logic high level to disable the device.
  • The maximum clock frequency supported by the CMP82C55AZ is 24 MHz.
  • The HOLD signal is used to pause the current operation and allow another master to access the bus. When the HOLD signal is asserted, the CMP82C55AZ will release the bus and enter a low-power state.
  • The RDY/BSY signal indicates the busy status of the device. When the signal is low, the device is busy and cannot accept new commands. When the signal is high, the device is ready to accept new commands.
