Features
The ESP-PSRAM64H is a 64Mbit (8MB) pseudo-static RAM (PSRAM) chip designed for Espressif’s ESP32 series. Key features:
- Interface: Octal SPI (8-bit) for high-speed data transfer (up to 144MHz).
- Capacity: 8MB (64Mbit) organized as 8M x 8 bits.
- Voltage: 3.3V operation, compatible with ESP32.
- Speed: Supports up to 144MHz clock speed (72MHz typical in ESP32).
- Low Power: Auto-sleep mode for reduced power consumption.
- Small Footprint: 24-pin SOP package (8x6mm).
- PSRAM Type: HyperBus-compatible, enhancing performance.
- Use Case: Extends ESP32 memory for high-speed caching, graphics, or data-intensive tasks.
Ideal for IoT, wearables, and embedded systems needing extra RAM without complex interfacing.

Pinout
The ESP-PSRAM64H is a 64Mbit (8MB) pseudo-static RAM (PSRAM) chip designed for Espressif's ESP32 series.
- Pin Count: 8-pin SOP package (common for SPI PSRAM).
- Interface: SPI (Serial Peripheral Interface)—typically uses Quad-SPI (QSPI) for high-speed data transfer.
- Voltage: Operates at 3.3V, compatible with ESP32's power supply.
- Function: Expands the ESP32's memory capacity, enabling faster access than flash for dynamic data (e.g., audio buffers, graphics).
Key features:
- High-speed (up to 104MHz clock in QSPI mode).
- Low power consumption.
- Pseudo-static (no refresh needed, unlike DRAM).
