The recommended crystal oscillator frequency for the LPC1313 is 12 MHz. However, the device can operate with a crystal frequency between 1 MHz and 25 MHz.
The pin multiplexing on the LPC1313 can be configured using the PINSELx registers. These registers allow you to select the function of each pin, such as GPIO, UART, SPI, etc.
The maximum operating temperature range for the LPC1313 is -40°C to +85°C. However, the device can be operated at a reduced temperature range of -40°C to +70°C for industrial applications.
The ADC on the LPC1313 can be used by configuring the ADC registers, such as the ADC Control Register (ADCR) and the ADC Channel Select Register (ADGDR). The ADC can be triggered using a software trigger or an external trigger.
The maximum current consumption of the LPC1313 depends on the operating frequency and the peripherals used. However, the typical current consumption is around 10 mA at 48 MHz with all peripherals enabled.
