ESP-PSRAM64H Chip - 64 Mbit Serial Psuedo SRAM - 3.3V 133 MHz
·
The ESP-PSRAM64H is a 64 Mbit (8 MB) serial pseudo SRAM chip in a compact SOIC-8 package. It provides fast, unlimited read/write external memory for microcontrollers like the ESP32 and Teensy 4.1, which have dedicated PSRAM pads or memory-mapping support for seamless integration. Unlike flash or...
GD25Q16 - 2MB SPI Flash in 8-Pin SOIC package
·
These little chips are like miniature SSD drives for your electronics. When you don't need something with as much storage as a micro SD card, but an EEPROM is too small, SPI (or QSPI) Flash chips give you on-the-order-of megabytes, with little cost and complexity. We use these chips all the time ...
