71342LA20PFG8 - Renesas Electronics

Description: The 71342 is a high-speed 4K x 8 Dual-Port Static RAM containing a fully independent semaphore logic block to assist in arbitrating between ports. This block contains unassigned flags which can be accessed by either side, however, only one side can control the flag at any time. An automatic power down feature, controlled by CE and SEM, permits the on-chip circuitry of each port to enter a very low standby power mode (both CE and SEM HIGH).

71342LA20PFG8 Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-1201) which includes thermal design considerations, such as thermal vias, copper pours, and component placement, to ensure optimal thermal performance.
  • Renesas recommends a specific power sequencing scheme in their datasheet, which involves powering up the VCC and VCCIO pins simultaneously, followed by the VREF pin. Additionally, the EN pin should be pulled high after the power supplies have stabilized.
  • The 71342LA20PFG8 has an operating temperature range of -40°C to +125°C, but it's essential to note that the device's performance and reliability may degrade at extreme temperatures. Consult the datasheet for specific temperature-related specifications.
  • The 71342LA20PFG8 is not specifically designed or tested for radiation-hardened applications. If radiation hardness is required, Renesas offers other products that are designed and qualified for such applications. Consult Renesas' radiation-hardened product portfolio for suitable alternatives.
  • Renesas recommends implementing ESD protection measures, such as TVS diodes or ESD protection arrays, on the I/O pins to prevent damage from electrostatic discharge. The specific ESD protection scheme may vary depending on the application and system requirements.
