Description:The 7025 is a high-speed 8K x 16 Dual-Port Static RAM designed to be used as a stand-alone 128K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more word systems. An automatic power down feature controlled by Chip Enable (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 QML is available.
Renesas provides a recommended PCB layout guide in their application notes, which includes thermal vias, thermal pads, and heat sink design considerations to ensure optimal thermal performance.
Renesas provides a Secure Boot and Firmware Encryption Guide that outlines the steps to implement secure boot and firmware encryption using the 7025L20JGI8's built-in security features, such as the Trusted Execution Environment (TEE) and the Advanced Encryption Standard (AES).
The internal oscillator has a typical accuracy of ±1.5% at room temperature. To improve its accuracy, you can use an external crystal oscillator or a high-precision external clock source. Additionally, you can calibrate the internal oscillator using the built-in calibration feature.
Renesas provides a Power Management Guide that outlines techniques for optimizing power consumption, such as using the low-power modes (e.g., Sleep, Stop, and Hibernate), reducing clock frequencies, and optimizing peripheral usage. You can also use the 7025L20JGI8's built-in power management features, such as the Power Management Controller (PMC) and the Voltage Regulator (VR).
Renesas provides an EMC/EMI Design Guide that outlines considerations for designing EMC-compliant systems, including PCB layout, component selection, and shielding. You should also follow the guidelines for reducing EMI emissions, such as using a common-mode choke and a ferrite bead.
