CMQ82C55AZ - 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

CMQ82C55AZ Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the CMQ82C55AZ is -40°C to 125°C.
  • The POR sequence for the CMQ82C55AZ involves applying power to the VCC pin, followed by a delay of at least 10ms to allow the internal voltage regulator to stabilize, and then releasing the reset pin (RST) to allow the device to start executing code.
  • The CMQ82C55AZ supports a maximum clock frequency of 55 MHz.
  • To configure the CMQ82C55AZ for low-power operation, you can use the power management registers to control the clock frequency, voltage, and power modes. You can also use the idle and sleep modes to reduce power consumption.
  • The maximum current consumption of the CMQ82C55AZ is approximately 50mA at 55MHz, but this can vary depending on the specific application and operating conditions.
