ESP8285H08

RF Transceiver ICS Overview

The ESP8285H08 is a highly integrated Wi-Fi System on Chip (SoC) manufactured by Espressif Systems. It features a RISC core operating at a maximum clock frequency of 160 MHz with a 32-bit data bus width. The device supports the 2.4 GHz band, delivering a maximum data rate of 72.2 Mbps and a transmitter output power of 19 dBm. Receiver sensitivity is rated at -70 dBm for n-mode. It includes 1 MB of SPI Flash memory. Operating voltage ranges from 2.7 V to 3.6 V, with receive current at 73 mA and transmit current at 197 mA. The component operates within a temperature range of -40°C to +105°C and is housed in a QFN-32 package measuring 5 mm x 5 mm x 0.85 mm.

RF Transceiver ICS Feature Summary

• Integrates Wi-Fi MAC, baseband, and RF transceiver into a single compact chip.
• Includes embedded 1 MB SPI Flash memory for code storage.
• Supports multiple digital interfaces including UART, SPI, I2C, and SDIO.
• Designed for low power consumption in IoT applications.

RF Transceiver ICS Applications

• Smart home devices requiring Wi-Fi connectivity
• Industrial automation controllers
• Wearable electronics with limited space

RF Transceiver ICS Procurement Notes

Verify the specific suffix H08 indicates 1 MB flash capacity, distinct from other variants like H16 which contain 2 MB. Confirm lifecycle status as NRND (Not Recommended for New Designs) before procurement. Ensure compatibility with existing PCB footprints for QFN-32 packages. Check humidity sensitivity handling requirements during assembly.

RF Transceiver ICS Selection Notes

Select this component when a compact Wi-Fi solution with integrated memory is required. Compare against ESP8266 variants if external flash is acceptable. Consider thermal performance given the high operating temperature range. Verify interface requirements match available GPIOs on the host system.

RF Transceiver ICS Part Context

The ESP8285 series belongs to Espressif's family of highly integrated Wi-Fi SoCs. It shares architectural similarities with the ESP8266 but integrates flash memory directly onto the chip. This integration reduces board space and simplifies manufacturing processes compared to solutions requiring external memory components.

RF Transceiver ICS Replacement Considerations

ESP8285H16: Identical functionality but with 2 MB SPI Flash instead of 1 MB. ESP8266EX: Requires external SPI Flash; different pinout and form factor considerations apply.
