This PSRAM is a 64 Mbit (8 Megabyte) serial pseudo SRAM device, organized in 8 M x 8 bits and housed in a compact SOIC-8 package. Crafted using high-performance CMOS technology, it operates at 3.3V with support for up to 133 MHz clock rates.
For applications requiring high speed, it supports the faster Quad Peripheral Interface (QPI) in addition to the standard Serial Peripheral Interface (SPI), allowing for flexible interfacing options. With access to unlimited reads and writes, it ensures reliable data storage and retrieval.
Ideal for enhancing ESP32 based boards or Teensy 4.1 systems, this PSRAM is best integrated with chips offering memory-mapping support for external PSRAM, delivering seamless performance for advanced applications.
