Design considerations
For controllers designed around asynchronous SRAM timing, parallel Toggle MRAM adds data persistence without battery backup. Address mapping, package pinout, bus width and read/write timing still need to match. MR5A16A automotive options use a 45 ns cycle; other listed production options use 35 ns.
