Product details
Overview
LPC11C14FBD48/30EL from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller designed for cost-sensitive industrial and sensor network applications, featuring 32 kB flash, 8 kB SRAM, one C_CAN controller, RS-485 UART, two SPI interfaces, 10-bit ADC with 8 channels, and 40 GPIO pins in a 48-pin LQFP package.
For engineers reviewing the LPC11C14FBD48/30EL datasheet, LPC11C14FBD48/30EL pinout, LPC11C14FBD48/30EL application, or LPC11C14FBD48/30EL equivalent, key selection criteria include CAN-enabled embedded control, Flash ISP via C_CAN or UART, Fast-mode Plus I²C (1 Mbit/s), and Deep power-down wake-up capability using dedicated GPIO pins.
Technical Context
The LPC11C14FBD48/30EL integrates an ARM Cortex-M0 core running at up to 50 MHz with a nested vectored interrupt controller (NVIC) and Serial Wire Debug interface. Its clock system combines a 12 MHz ±1% internal RC oscillator, external crystal support (1–25 MHz), and a programmable PLL enabling full-speed operation without high-frequency crystals.
Power management includes three low-power modes-Sleep, Deep-sleep, and Deep power-down-with wake-up from Deep power-down supported on 13 GPIO pins. The device lacks an on-chip CAN transceiver (unlike LPC11C22/C24), requiring external CAN PHY for physical layer connectivity.

FAQ
What is the maximum operating frequency of the LPC11C14FBD48/30EL?
The LPC11C14FBD48/30EL operates at a maximum CPU frequency of 50 MHz. This speed is achieved using either the internal 12 MHz ±1% RC oscillator with PLL multiplication or an external crystal (1–25 MHz) fed into the PLL. The device maintains full peripheral functionality-including C_CAN, UART, and ADC-at this clock rate, enabling real-time response in industrial control loops.
Does the LPC11C14FBD48/30EL include an integrated CAN transceiver?
No, the LPC11C14FBD48/30EL does not include an on-chip CAN transceiver. It features only the C_CAN controller (a protocol-level IP block). Physical layer connectivity requires an external CAN transceiver such as the TJA1042 or SN65HVD230. In contrast, the LPC11C22/C24 variants integrate a high-speed CAN transceiver-making LPC11C14FBD48/30EL suitable for designs where transceiver selection or layout optimization is preferred.
How many ADC channels does the LPC11C14FBD48/30EL support, and what is its resolution?
The LPC11C14FBD48/30EL includes a 10-bit successive approximation ADC with multiplexing across eight input channels (AD0–AD7). Each channel maps to a dedicated GPIO pin (e.g., AD0 = PIO0_11, AD4 = PIO1_3), and the ADC supports configurable sample rates, burst mode, and hardware trigger sources including timers and interrupts-enabling synchronized analog acquisition in sensor and metering applications.
Can the LPC11C14FBD48/30EL perform in-system programming via CAN bus?
Yes, the LPC11C14FBD48/30EL supports Flash In-System Programming (ISP) via the C_CAN interface. When PIO0_1 and PIO0_3 are both held LOW during reset, the on-chip bootloader activates CAN-based ISP mode. This allows field firmware updates over existing CAN infrastructure without requiring UART access or debug probes-critical for sealed or remotely deployed devices like smart meters.
What package type and pin count does the LPC11C14FBD48/30EL use?
The LPC11C14FBD48/30EL uses a 48-pin LQFP package (SOT313-2) with dimensions 7 × 7 × 1.4 mm. This RoHS-compliant package provides 40 GPIO pins plus dedicated power, ground, reset, clock, debug, and peripheral interface pins-including CAN_RXD/CAN_TXD, UART, SPI, I²C, and ADC inputs-enabling compact yet highly functional PCB layouts for industrial control modules.
