  • Removing some Pentalobe screws allows us to get a peek at this MacBook's internals.

  • The silicon buried underneath the trackpad doesn't appear to be any different from last year's MacBook. We find a handful of ICs:

  • Broadcom BCM5976 touchscreen controller

  • STMicroelectronics STM32F103 32-Bit ARM Cortex-M3 microcontroller

  • Monolithic Power Systems MP24830 white LED backlight driver and an International Rectifier IRFH3702 single N-channel HEXFET power MOSFET (likely for driving keyboard backlight LEDs)

  • Texas Instruments TMP421 temperature sensor and Bosch Sensortec BMA282 accelerometer

  • Macronix MX25L2006E 2 MB Serial NOR Flash

  • Maxim Integrated MAX11290 24-bit delta-sigma analog-to-digital converter (likely)

Nach dem Entfernen einiger Pentalobe Schrauben, können wir einen ersten Blick in das Innere werfen.

Das Silizium, das unter dem Trackpad vergraben ist, scheint sich nicht vom letztjährigen MacBook zu unterscheiden. Wir finden drei identische ICs:
