LPC4357JET256 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LPC4357JET256?
  The maximum operating temperature range for the LPC4357JET256 is -40°C to +105°C, but this can be extended to -40°C to +125°C for some specific applications with proper derating.
• How do I configure the boot mode for the LPC4357JET256?
  The boot mode for the LPC4357JET256 can be configured using the boot pins (P2_7 and P2_8) and the ISP (In-System Programming) mode. The boot mode can be set to boot from the internal flash, external flash, or SPIFI (SPI Flash Interface).
• What is the maximum clock frequency for the LPC4357JET256?
  The maximum clock frequency for the LPC4357JET256 is 204 MHz, but this can be adjusted using the clock control unit (CCU) and the power management unit (PMU) to optimize power consumption and performance.
• How do I use the SPIFI interface on the LPC4357JET256?
  The SPIFI interface on the LPC4357JET256 can be used to connect to external SPI flash devices. The SPIFI interface is configured using the SPIFI registers and the flash device is accessed using the SPIFI API provided in the LPC4357JET256 software development kit (SDK).
• What is the power consumption of the LPC4357JET256 in different operating modes?
  The power consumption of the LPC4357JET256 varies depending on the operating mode. In active mode, the power consumption is around 350 mA at 204 MHz. In sleep mode, the power consumption is around 10 mA, and in deep sleep mode, it is around 1 mA. The power consumption can be further optimized using the power management unit (PMU) and the clock control unit (CCU).
