RF Transceiver ICS datasheet and documents for ESP32-H2FH4
RF Transceiver ICS Overview
The ESP32-H2FH4 is a single-core RISC-V System-on-Chip designed for low-power, secure wireless connectivity. It integrates IEEE 802.15.4 and Bluetooth Low Energy (BLE) 5.0 capabilities within a compact QFN 32-pin package measuring 4mm x 4mm. The device includes 4 MB of internal flash memory and 320 KB of SRAM. It operates across an extended temperature range from -40°C to +105°C, supporting industrial applications.
RF Transceiver ICS Feature Summary
- Supports dual-mode wireless communication combining IEEE 802.15.4 and Bluetooth Low Energy 5.0 protocols.
- Integrates a high-performance RISC-V single-core processor with substantial on-chip memory resources.
- Features a compact surface-mount package suitable for space-constrained IoT designs.
RF Transceiver ICS Applications
- Smart home sensor nodes requiring Thread or Zigbee connectivity
- Matter-over-Thread battery-powered devices
- Industrial monitoring equipment operating in wide temperature ranges
RF Transceiver ICS Procurement Notes
Verify component status carefully as the ESP32-H2FH4 is listed as End-of-Life by the manufacturer. Production cessation is imminent, necessitating immediate evaluation of alternative solutions or sufficient stock acquisition for current projects. Confirm specific chip revision requirements against design specifications before procurement.
RF Transceiver ICS Selection Notes
Select this SoC when designing devices requiring both BLE and 802.15.4 support without Wi-Fi functionality. The integrated 4 MB flash reduces external component count compared to variants requiring off-chip storage. Ensure development environments support the required ESP-IDF versions for protocol stack compatibility.
RF Transceiver ICS Part Context
This component belongs to the ESP32-H2 family, which targets ultra-low-power IoT applications. Unlike the ESP32-C6 which includes Wi-Fi, the H2 series focuses exclusively on BLE and 802.15.4 to optimize power consumption and cost for mesh networking and sensor applications.
RF Transceiver ICS Replacement Considerations
ESP32-H2FH4S: Chip revision v1.2 and above variant with identical specifications.
RF Transceiver ICS FAQ
Does the ESP32-H2FH4 support Wi-Fi connectivity?
