An Espressif ESP32-P4 teardown and die shots

The electronupdate blog takes an Espressif ESP32-P4 module and does a teardown inside the shield and into the chips for die shots.

I recently purchased a “Guition” JC-ESP32P4-M3 which combines the P4 with the C6.

The P4 is Espressif’s the fastest offering with a 360 MHz RISC-V processor core.  To enable WiFi and Bluetooth, a ESP-C6 is on the same assembly.

Removing the metal shield reveals the 3 major bits of silicon:

– ESP32-P4:  star of this show… actually two bits of silicon the PSRAM is glued to the top of the P4
– ESP32-C6: providing Bluetooth and WIFI
– Boya 25Q128 SPI NOR Flash for program storage
