7132SA55CB - Renesas Electronics

Description: The 7132 is a high-speed 2K x 8 Dual-Port Static RAM designed to be used as a stand-alone 8-bit Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the 7142 "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 standby power mode. Military grade product in compliance with MIL-PRF-38535

7132SA55CB Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN3804EU0100) which includes thermal design considerations, such as placing thermal vias under the package and using a solid ground plane to reduce thermal resistance.
  • To ensure reliable operation in high-temperature environments, it's essential to follow the recommended operating conditions, use a suitable thermal design, and consider derating the device's power consumption. Additionally, Renesas provides a thermal derating chart in the datasheet to help with this process.
  • The input capacitor (CIN) should have a low ESR and be rated for the input voltage. A 10uF to 22uF ceramic capacitor is recommended. The output capacitor (COUT) should also have a low ESR and be rated for the output voltage. A 10uF to 47uF ceramic capacitor is recommended. Refer to the datasheet for more detailed guidance.
  • To troubleshoot issues with the power-good (PG) output, check the input voltage, output voltage, and output current. Ensure that the input voltage is within the recommended range, and the output voltage is within the specified tolerance. Also, verify that the output current is not exceeding the maximum rating. If the issue persists, consult the datasheet and application notes for further guidance.
  • If the enable (EN) pin is not used, the device will always be in the enabled state, which may lead to increased power consumption and heat generation. It's recommended to use the EN pin to control the device's power state, especially in battery-powered applications.
