R1LV0408DSP-5SI General Description

R1LV0408DSP-5SI is a specific type of semiconductor memory chip manufactured by Renesas Electronics Corporation.



  • It has a capacity of 4 megabits (4 Mb) or 512 kilobytes (512 KB) of memory.
  • It uses a low-power CMOS technology, which allows it to consume very little power.
  • It operates at a clock speed of 5 nanoseconds (5 ns), which means it can perform read and write operations very quickly.
  • It has a single 3.3V power supply.


  • R1LV0408DSP-5SI can be used in a wide range of electronic devices that require non-volatile memory, such as routers, switches, modems, and printers.
  • It is commonly used as a boot memory, where the device reads instructions from the chip during startup.
  • It can also be used as a program memory, where the device stores application code.
