Refer to https://aiot.realmcu.com/en/product/index.html for details.

What is psram?

PSRAM (Pseudo Static Random Access Memory) is a type of memory that combines the ease-of-use of SRAM with the high-density characteristics of DRAM. It achieves an SRAM-like interface through dynamic refresh mechanisms. Refer to https://aiot.realmcu.com/en/latest/rtos/peripherals/psram/index.html for details.

What is PSRAM and how does it differ from SRAM?

PSRAM (Pseudo Static Random Access Memory) combines SRAM's ease-of-use with DRAM's high density. Unlike traditional SRAM, PSRAM uses dynamic refresh internally while presenting an SRAM-like interface. Realtek Ameba IoT SoCs support both QSPI PSRAM and DDR PSRAM for flexible memory expansion.

What are the advantages of Wi-Fi 6 over Wi-Fi 4 in IoT?

Wi-Fi 6 (802.11ax) offers:
1) OFDMA for efficient multi-device communication (75% latency reduction).
2) Target Wake Time (TWT) for extended battery life.
3) Higher throughput (114.7Mbps on 2.4GHz).
4) Better dense IoT deployment performance.
Realtek's RTL8720E and RTL8710E leverage these for next-gen smart home and industrial IoT.

How does Bluetooth 5.3 improve battery life?

Bluetooth 5.3 features:
1) Enhanced Connection Update mechanism.
2) Periodic Advertising Sync Transfer (PAST).
3) Improved channel selection.
4) Lower duty cycle (13.9µA deep sleep on RTL8721Dx).
Combined with Realtek's power management, devices achieve years of battery life on a single coin cell.

What is Arm TrustZone-M and why is it important?

Arm TrustZone-M creates hardware-enforced secure execution on Cortex-M processors, partitioning resources into Secure/Non-Secure domains. Realtek Ameba IoT SoCs (RTL8721Dx, RTL8730E) implement TrustZone with PSA Level 2/3 certification, Secure Boot, OTP storage, and hardware crypto engines (AES/SHA/ECDSA).

What is Wi-Fi R-MESH and how does it extend coverage?

Wi-Fi R-MESH is Realtek's tree-topology mesh networking creating multi-hop wireless paths: Root Node (AP) → Intermediate Nodes → Leaf Nodes. Benefits: 1) 300% coverage extension vs single AP, 2) Self-healing network, 3) Lower latency than traditional mesh, 4) Supports 100+ nodes. Ideal for smart homes, industrial IoT, outdoor surveillance.

How to choose between RTL8721Dx, RTL8720E, RTL8730E?
