Serial PSRAM,SRAM has low pin count, smaller package size and low power consumption.
Ideal for IoT and wearable device applications.
Serial PSRAM:
- Using advanced DRAM process technology to reduce the chip size, cost effective.
- No refresh cycles needed because of the emerging design technology.
- The 64M memory size is much larger than the other serial interface RAM in the current market.
Serial SRAM:
- Using low power SRAM process technology.
- Wider power supply range.
- very low standby current.
