Espressif to Launch ESP8285 WiSoC Variants with Extended Industrial Temperature Range

Espressif Systems first introduced ESP8285 WiFi SoC in 2016. The chip is similar to ESP8266 WiFi chip but includes 1MB flash making it more suitable for space-constrained applications since an external flash chip is not required.

Since the launch, we’ve seen several modules and final products based on the solution including ESP-WROOM-5C and PSF-A85 modules, as well as Sonoff B1 WiFI RGB light bulb.

The original chip (ESP8285N08) would work in -40°C to 85°C industrial temperature range, but in their recent newsletter, the company announced plans to launch two new variants in the ESP8285 series with an extended temperature range up to 105°C and different flash capacities:

  • ESP8285H16 with 2 MB flash, -40°C to +105°C operating temperature range
  • ESP8285H08 with a 1 MB flash, -40°C to +105°C operating temperature range

ESP8285H16 is slated to launch at the end of August 2019, and the company plans to provide more details next month, but I could already see both variants mentioned in the latest version of the datasheet.

They were promoting the ESP8285 as for wearables if I remember correctly. I think I have one in my collection…
