MD82C54/B - Renesas Electronics

Description: The Intersil 82C54 is a high performance CMOS Programmable Interval Timer manufactured using an advanced 2 micron CMOS process. The 82C54 has three independently programmable and functional 16-bit counters, each capable of handling clock input frequencies of up to 8MHz (82C54) or 10MHz (82C54-10) or 12MHz (82C54-12). The High-Speed and industry standard configuration of the 82C54 make it compatible with the Intersil 80C86, 80C88, and 80C286 CMOS microprocessors along with many other industry standard proces

MD82C54/B Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the MD82C54/B is 4.5V to 5.5V.
  • The POR circuitry in the MD82C54/B is designed to reset the device during power-up. To handle it, ensure that the power supply voltage rises slowly (typically 10ms to 100ms) to allow the POR circuitry to stabilize.
  • The maximum clock frequency supported by the MD82C54/B is 24MHz.
  • The MD82C54/B has a multiplexed address/data bus. To interface with external memory devices, use the chip select signals (CS0-CS3) to select the desired memory device and ensure proper address decoding.
  • The WAIT input pin is used to insert wait states during memory access. When the WAIT pin is low, the MD82C54/B will insert wait states until the WAIT pin goes high, allowing for slower memory devices to respond.
