  • 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)

Retirar algunos tornillos Pentalobe nos permite echar un vistazo a las partes internas de esta MacBook.

El silicio enterrado debajo del trackpad no parece ser diferente del MacBook del año pasado. Encontramos un puñado de circuitos integrados:

Controlador de pantalla táctil Broadcom BCM5976

Microcontrolador STMicroelectronics STM32F103 ARM Cortex-M3 de 32 bits

Controlador de retroiluminación LED blanco MP24830 de Monolithic Power Systems y un MOSFET de potencia HEXFET de canal N único IRFH3702 de International Rectifier (probablemente para controlar los LED de retroiluminación del teclado)

Sensor de temperatura Texas Instruments TMP421 y acelerómetro Bosch Sensortec BMA282

Macronix MX25L2006E Flash NOR serie de 2 MB

Maxim Integrated MAX11290 Convertidor de analógico a digital delta-sigma de 24 bits (probable)
