Description:The 71256 5V CMOS SRAM is organized as 32K x 8. The circuit also offers a reduced power standby mode for significant system level power and cooling savings. The low-power (L) version also offers a battery backup data retention capability allowing operation off a 2V battery. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation. Military grade product is available.
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 in a specific order. Additionally, they provide a power sequencing diagram in their application note (APL-AN-1202) to ensure proper device operation.
Renesas recommends using high-frequency, low-ESR decoupling capacitors (e.g., 100nF, 1uF, and 10uF) placed close to the device's power pins to minimize noise and ensure stable operation. The exact values and placement can be found in the datasheet and application notes.
Renesas provides guidelines for JTAG interface handling during production testing in their application note (APL-AN-1203). This includes information on JTAG pin configuration, signal integrity, and testing procedures to ensure reliable device programming and testing.
Renesas provides thermal design guidelines in their application note (APL-AN-1201) which include thermal resistance calculations, heat sink design recommendations, and thermal interface material selection to ensure reliable operation in high-temperature environments.
