The internal oscillator saves a crystal for UART or I2C operation, though a precision clock improves USB jitter margins if the layout allows. ## 16 KB Flash — firmware budget matters 16 KB of program Flash and 4 KB of SRAM place this part at the low end of the LPC13xx memory map. That is enough for a USB CDC virtual COM port with a command parser, or a Modbus RTU slave with a few analog inputs, but tight for a full TCP/IP stack or a graphical UI. The 8-channel 10-bit ADC covers basic sensor readout without an external converter.","metaTitle":"NXP LPC1342FBD48,118 ARM Cortex-M3 MCU, 72 MHz, 16 KB Flash","metaDescription":"NXP LPC1342FBD48,118 32-bit ARM Cortex-M3 MCU, 72 MHz speed, 16 KB Flash, 4 KB RAM, 42 I/O, USB, -40 to 85 °C, 48-LQFP.
