Functional problems detail 3.1 RTC.1: The RTC oscillator changes from bypass control mode to crystal mode when waking up from Deep power-down mode. Introduction: On the LPC5410x, the low power 32 KHz RTC oscillator can be configured to run in crystal oscillation mode or bypass control mode. In crystal oscillation mode, the RTC oscillator is driven by an external 32 KHz crystal and in bypass control mode, the RTC oscillator is driven by an external 32 KHz clock. Bypass control mode can be entered by setting the PDEN_32K_OSC bit in the PDRUNCFG register (bit 24). Problem: The PDEN_32K_OSC bit gets cleared when the MCU wakes up from Deep power-down mode. This causes the RTC oscillator to change from bypass mode to crystal mode. Work-around: If using deep power-down mode, the crystal oscillation mode should be used instead of the bypass crystal mode. The bypass crystal mode can be used in active, sleep, deep-sleep, and power-down modes. 3.2 ISP.1: ISP (In-System Programming) command for UID (unique identification number) is not functional. Introduction: Each LPC5410x device contains a device serial number (four 32-bit words) for unique identification. The ISP call (ReadUID) can be performed via the USART interface to read the unique serial number where the word at the lowest address is sent first. Problem: On the LPC5410x, the read UID ISP command is not functional. Work-around: The unique serial number (four 32-bit words) can be directly read from address locations 0x01800100 to 0x0180010C.

All rights reserved. 5 of 8 ES_LPC5410x NXP Semiconductors Errata sheet LPC5410x 3.3 Frequency.1: The maximum operating system clock on the LPC5410x device is limited to 96 MHz. Introduction: The LPC5410x data sheet specifies that the LPC5410x device can operate at CPU frequencies up to 100 MHz. Problem: To guard band for process, voltage, and temperature, the operating frequency is limited to 96 MHz. Work-around: None. Use CPU frequencies 96 MHz. 4.
