Product details
Overview
LPC1113FBD48/303 from NXP Semiconductors is an ARM Cortex-M0 32-bit microcontroller in LQFP48 package, delivering up to 50 MHz CPU operation, 24 kB flash, 8 kB SRAM, and integrated peripherals including UART with RS-485 support, two SPI interfaces, Fast-mode Plus I²C (1 Mbit/s), 10-bit ADC (8-channel), and four general-purpose timers - used in industrial control nodes requiring low-power, deterministic real-time response.
For engineers reviewing the LPC1113FBD48/303 datasheet, LPC1113FBD48/303 pinout, LPC1113FBD48/303 application, or LPC1113FBD48/303 equivalent, key selection criteria include its LPC1100XL series power profiles, windowed watchdog timer, configurable open-drain GPIO, and full 42-pin GPIO availability in LQFP48 - critical for mixed-signal embedded designs with space-constrained PCB layouts.
Technical Context
The LPC1113FBD48/303 implements the ARM Cortex-M0 core with Nested Vectored Interrupt Controller (NVIC) and supports Serial Wire Debug (SWD). Its clock system integrates a 12 MHz ±1 % internal RC oscillator, crystal oscillator (1–25 MHz), programmable watchdog oscillator (9.4 kHz–2.3 MHz), and PLL for flexible CPU clock derivation.
As part of the LPC1100XL series, it includes power management unit (PMU)-driven Sleep, Deep-sleep, and Deep power-down modes, plus boot ROM-resident power profiles enabling runtime optimization of performance vs. current consumption via single function call - distinct from base LPC1100 and LPC1100L variants.

FAQ
What is the maximum operating frequency of the LPC1113FBD48/303?
The LPC1113FBD48/303 operates at a maximum CPU frequency of 50 MHz, achievable via its integrated PLL driven by either the internal 12 MHz RC oscillator or an external crystal (1–25 MHz). This frequency is fully supported across its specified temperature range (−40 °C to +85 °C) and supply voltage (1.8 V to 3.6 V), enabling deterministic real-time execution for industrial control tasks.
Does the LPC1113FBD48/303 support in-system programming (ISP)?
Yes, the LPC1113FBD48/303 supports In-System Programming (ISP) via its on-chip bootloader, accessible through UART using standard ISP commands. It also supports In-Application Programming (IAP) for firmware updates without halting main application execution - both features are enabled by default and require no external programming hardware beyond a UART interface.
How many ADC channels does the LPC1113FBD48/303 have, and what is their resolution?
The LPC1113FBD48/303 integrates a single 10-bit successive approximation register (SAR) ADC with input multiplexing across 8 dedicated pins (AD[7:0]). This configuration supports simultaneous sampling of up to eight analog sources - such as temperature sensors, voltage dividers, or current shunts - with typical integral nonlinearity (INL) better than ±1 LSB, meeting industrial measurement requirements.
Is the LPC1113FBD48/303 pin-compatible with other LQFP48 variants in the LPC111x family?
Yes, the LPC1113FBD48/303 shares identical pinout and electrical characteristics with all LQFP48-packaged LPC111x parts (e.g., LPC1114FBD48/303, LPC1115FBD48/303), including matching power, ground, reset, clock, SWD, UART, SPI, I²C, ADC, and GPIO assignments - enabling hardware reuse across flash-size variants within the same temperature grade (F = −40 °C to +85 °C).
What power-saving features are unique to the LPC1113FBD48/303 within the LPC1100XL series?
The LPC1113FBD48/303 inherits LPC1100XL-series power features including Sleep, Deep-sleep, and Deep power-down modes managed by the integrated PMU, plus boot ROM-resident power profiles that allow runtime selection of optimized performance/power trade-offs via a single function call - a capability absent in base LPC1100 and LPC1100L variants.
