DESCRIPTION
A PSRAM uses on-chip refresh circuitry with a DRAM memory cell for pseudo static operation which eliminates external clock inputs, while considering the pinout compatibility with industry standard SRAMs. The LH5P8129 PSRAM has a built-in oscillator, which makes it easy to refresh memories without external clocks.
