Product details
Overview
LPC1114FBD48/301 from NXP Semiconductors is an ARM Cortex-M0 32-bit microcontroller in LQFP48 package, operating at up to 50 MHz with 32 kB flash, 8 kB SRAM, and 42 GPIO pins. It integrates UART with RS-485 support, dual SPI (SSP), Fast-mode Plus I²C, four timers, and a 10-bit ADC-targeted for cost-sensitive industrial control and smart sensor nodes.
For engineers reviewing the LPC1114FBD48/301 datasheet, LPC1114FBD48/301 pinout, LPC1114FBD48/301 application, or LPC1114FBD48/301 equivalent, key selection criteria include its LQFP48 footprint, absence of power profiles (LPC1100 series), 32 kB flash capacity, and full peripheral set including dual SPI and 10-bit ADC with 8-channel multiplexing.
Technical Context
The LPC1114FBD48/301 implements the ARM Cortex-M0 core with NVIC and Serial Wire Debug, executing from on-chip flash with zero-wait-state access up to 50 MHz. Its clock system combines a 12 MHz ±1% internal RC oscillator, external crystal (1–25 MHz), and PLL for flexible frequency synthesis without requiring high-frequency crystals.
Peripheral integration includes two independent SPI controllers (SPI0/SPI1) with FIFO and multi-protocol capability, one UART with fractional baud rate generation and RS-485 support, and a Fast-mode Plus I²C interface supporting 1 Mbit/s data rates and monitor mode-enabling robust communication in noisy industrial environments.

FAQ
What is the maximum operating frequency of the LPC1114FBD48/301?
The LPC1114FBD48/301 operates at a maximum CPU frequency of 50 MHz. This is achieved using the on-chip PLL driven by either the internal 12 MHz RC oscillator or an external crystal (1–25 MHz). The core executes instructions with zero wait states at this speed, enabling deterministic real-time response in control applications.
Does the LPC1114FBD48/301 support power profiling features?
No, the LPC1114FBD48/301 belongs to the base LPC1100 series and does not include power profiles in boot ROM. Power profiling-enabling runtime optimization of performance versus power consumption via a single function call-is only available in LPC1100L and LPC1100XL variants such as LPC1114FBD48/302 or LPC1114FBD48/303.
How many analog input channels does the LPC1114FBD48/301 ADC support?
The LPC1114FBD48/301 integrates a 10-bit ADC with input multiplexing across eight pins (AD[7:0]), all available on the LQFP48 package. This allows simultaneous sampling of up to eight analog sources-such as temperature, voltage, or current sensors-with configurable sample rates up to 400 kS/s.
Is the LPC1114FBD48/301 pin-compatible with other LQFP48 variants in the LPC111x family?
Yes, the LPC1114FBD48/301 shares identical pinout and package dimensions (LQFP48, SOT313-2) with all other LQFP48-packaged LPC111x parts-including LPC1113FBD48/301, LPC1114FBD48/302, and LPC1115FBD48/303-enabling drop-in replacement where flash, SRAM, or feature requirements align.
What debug interface does the LPC1114FBD48/301 use?
The LPC1114FBD48/301 uses Serial Wire Debug (SWD), a two-pin (SWDIO and SWCLK) ARM-standard debug interface. It supports full programming, real-time debugging, breakpoints, and memory inspection without requiring JTAG pins, conserving I/O resources on the LQFP48 package.
