- The flash supports: - More than 100,000 program/erase cycles - More than 20 years data retention time 5 Customized version operating at –40∼ 105 °C is available.
- If you have a requirement for a higher flash clock frequency of 120 MHz or if you need the flash auto suspend feature, pleasecontact us.
- Both ESP32-C3-WROOM-02 and ESP32-C3-WROOM-02U has two operating ambient temperature options: –40 ∼ 85 °C variants and –40∼ 105 °C variants, all embedded with the ESP32-C3 chip.
- BCK clock frequency, from 10 kHz up to 40 MHz, is supported.
- The temperature sensor has a range of –40 °C to 125 °C.
- The temperature value depends on factors like microcontroller clock frequency or I/O load.

- Revision History
Engineering review checklist
- Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
- Check package pinout, boot configuration, programming interface and silicon-revision errata.
- Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
