El transceptor Wi-Fi 2T2R de 2,4 GHz en chip admite velocidades de datos de hasta 300 Mbps con TXBF, STBC, LDPC-Tx y MRC. Entre los periféricos clave se incluyen PCIe Gen1 Host, 2× USB 2.0, 2× SPI, 3× UART, 2× I2C, I2S, PCM, SDXC/eMMC, 4× PWM y un motor de seguridad por hardware con aceleración AES/DES/SHA. Fabricado en un proceso de 28 nm y empaquetado en un DR-QFN128 de 10×10 mm, el RTL8197H-VE5-CG está diseñado para routers inteligentes de doble banda, sistemas Wi-Fi en malla, puntos de acceso inalámbricos y pasarelas IoT.

El RTL8197H-VE5-CG es un WiSoC (sistema en chip inalámbrico) 802.11b/g/n 2T2R altamente integrado fabricado por Realtek Semiconductor Corp. Pertenece a la familia RTL8197F y está fabricado en un nodo de proceso de 28 nm. El chip integra un procesador MIPS 24Kc a 1GHz con 64KB I-Cache y 32KB D-Cache, un transceptor inalámbrico 2T2R 802.11b/g/n MAC/BB/RF que alcanza una velocidad PHY de hasta 300Mbps, un conmutador Fast Ethernet de 5 puertos a 10/100Mbps configurable como 5 FE PHY o 1 RGMII + 4 FE PHY, dos controladores host USB 2.0, 128MB de memoria RAM y un puerto USB 2.0 para la conexión a Internet.0, 128 MB de SDRAM DDR2 integrada (paquete MCM) e interfaces periféricas completas que incluyen PCIe Gen1 Host, SPI, UART, I2C, I2S, PCM, SDXC/eMMC y GPIO. La variante RTL8197H se diferencia de los demás miembros de la serie RTL8197F por su conmutador FE de 5 puertos compatible con el enlace ascendente RGMII para Gigabit Ethernet, lo que la hace ideal para routers con varios puertos LAN y nodos Wi-Fi en malla. Un motor de seguridad por hardware admite criptografía AES/DES/SHA, y un controlador GDMA de 4 canales descarga las tareas de transferencia de datos. El chip es compatible con Wi-Fi EasyMesh y está ampliamente adoptado en productos comerciales como H3C NX15 (AX1500) y D-Link DIR-841 (AC1200).

1. Subsistema de procesador: La CPU MIPS 24Kc funciona hasta a 1GHz con 64KB I-Cache y 32KB D-Cache, ejecutando el kernel Linux embebido, la pila de protocolos de red (TCP/IP, NAT, firewall), y el software de capa de aplicación a través de una estructura de bus AMBA interna.
2. Subsistema inalámbrico: El transceptor 2T2R 802.11b/g/n MAC/BB/RF de 2,4 GHz está totalmente integrado en el chip y admite anchos de banda de canal HT20/HT40 con procesamiento MIMO para una velocidad PHY de hasta 300 Mbps. El PA/LNA integrado minimiza los componentes de RF externos. Soporta Transmit Beamforming (TxBF), STBC, LDPC-Tx y MRC-Rx para mejorar la fiabilidad del enlace.
3. Subsistema de conmutación Ethernet: Un conmutador Fast Ethernet de 5 puertos a 10/100 Mbps admite la asignación de puertos configurable: modo 5 FE PHY o 1 RGMII + 4 FE PHY. La interfaz MAC RGMII se conecta a una PHY Gigabit externa (por ejemplo, RTL8211F) para WAN/LAN 1000M, con Auto MDI/MDIX en todos los puertos FE.
4. Subsistema de memoria: 128 MB de SDRAM DDR2 integrados en el MCM. El controlador de memoria soporta SPI NOR Flash (hasta 128MB), SPI NAND Flash (hasta 4Gbit), y Parallel NAND Flash (hasta 8GB) para almacenamiento de firmware. Los diseños típicos utilizan 16MB SPI NOR Flash.
5. Subsistema de interfaz periférica: La rica E/S incluye 1x PCIe Gen1 Host, 2x USB 2.0, 2x SPI, 3x UART, 2x I2C, 1x I2S, 1x PCM, 4x PWM y 1x SDXC/eMMC para IoT flexible, VoIP y expansión de almacenamiento.
6. Motor de aceleración por hardware: Un motor de seguridad dedicado admite criptografía por hardware AES/DES/SHA-1/SHA-256 para VPN y descarga de cifrado WPA. El controlador GDMA proporciona 4 canales DMA independientes para transferencias de memoria a memoria y de memoria a periféricos sin intervención de la CPU.
