Figure 5 : SRAM erased with random data during Power down sequence As shown in Figure 5, State Machine starts writing the following sequence on CPU Clock as it gets the indication from the Standby ...

Whereas SRAM chips can be more or less directly hooked up to the CPU’s address and data buses, a DRAM setup needs refresh circuitry to ensure the data doesn’t leak out of the chips’ internal ...

The CPU can then quickly read from and write to the RAM, enabling the rapid execution of tasks. As more programs are opened or more data is processed, the RAM becomes increasingly occupied. Static RAM ...

The RA4L1 MCUs employ proprietary low-power technology that delivers 168 µA/MHz active mode @ 80 MHz and standby current of just 1.70 µA with all the SRAM retained. They also are available in very ...
