The 58K x 8 RAM holds Ethernet frame buffers and a CAN message queue. ## On-chip data converters and peripherals The device includes an 8-channel 10-bit SAR ADC and a single 10-bit DAC — adequate for reading analog sensors (temperature, pressure, potentiometer feedback) and generating a control voltage or analog output signal. The peripheral set also includes a brown-out detect/reset, DMA controller, I²S audio interface, PWM, and watchdog timer. The oscillator can be driven from an external crystal or an internal RC oscillator, though the internal oscillator is not precise enough for USB or Ethernet without an external clock source.","metaTitle":"NXP LPC2378FBD144K ARM7 MCU, 72 MHz, 512 KB Flash, Ethernet + CAN","metaDescription":"NXP LPC2378FBD144K ARM7 MCU, 72 MHz, 512 KB Flash, 58K RAM, Ethernet, CAN, USB, 104 I/O, -40 to 85°C, 144-LQFP.

These interfaces share the internal 58K x 8 RAM and DMA controller, so you can run all three simultaneously for a multi-protocol gateway design."},{"question":"What voltage does LPC2378FBD144K operate at?","answer":"The supply voltage range is 3.0 V to 3.6 V (Vdd/Vcc). The I/O pins are 3.3 V tolerant; the core runs from an internal 1.8 V regulator. Do not apply 5 V to any pin without level translation."},{"question":"What is the package of LPC2378FBD144K?","answer":"The LPC2378FBD144K is supplied in a 144-lead LQFP package (20x20 mm body, 0.5 mm pitch). It is a surface-mount package, shipped in tray format."},{"question":"What are the key differences between LPC2378FBD144K and LPC2378FBD144?","answer":"The LPC2378FBD144K and LPC2378FBD144 are functionally identical — same ARM7 core at 72 MHz, same 512 KB Flash, same 58K x 8 RAM, same peripheral set including Ethernet, CAN, and USB. The suffix 'K' typically denotes a specific ordering code variant, often related to packaging or temperature range. The base product number is LPC2378 for both; the datasheet covers both ordering codes. For pinout and electrical specifications, they are interchangeable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp-usa-inc/LPC2378FBD144K","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp-usa-inc/LPC2378FBD144K when reusing this data.
