71321LA20PFG - Renesas Electronics

Description: The 71321 is a high-speed 2K x 8 Dual-Port Static RAM with internal interrupt logic for interprocessor communications. It is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the 71421 "SLAVE" Dual-Port in 16-bit-or-more word width systems which would result in full-speed, error free operation without the need for additional discrete logic. An automatic power down feature, controlled by CE, permits the on chip circuitry of each port to enter a very low sta

71321LA20PFG Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended for optimal thermal performance. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
  • To ensure reliable operation across the entire operating temperature range, it is essential to follow the recommended operating conditions, including voltage, current, and power dissipation. Additionally, the device should be operated within the specified junction temperature range.
  • The critical timing parameters for the 71321LA20PFG include clock frequency, setup and hold times, and propagation delay. To ensure these parameters are met, it is essential to follow the recommended clocking scheme, signal routing, and termination guidelines.
  • Power sequencing and reset signals should be handled according to the recommended power-up and power-down sequences outlined in the datasheet. The reset signal should be asserted for a minimum duration to ensure proper device initialization.
  • The 71321LA20PFG is a sensitive device and requires proper ESD protection and handling procedures to prevent damage. It is recommended to follow standard ESD handling procedures, including the use of ESD-safe materials, wrist straps, and ionizers.
