Product details
Overview
LPC1113FBD48/301 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in LQFP48 package, operating at up to 50 MHz with 24 kB flash, 8 kB SRAM, one UART with RS-485 support, one Fast-mode Plus I²C-bus interface, two SPI controllers, four general-purpose timers, and a 10-bit ADC-designed for cost-sensitive industrial control and smart sensor node applications.
For engineers reviewing the LPC1113FBD48/301 datasheet, LPC1113FBD48/301 pinout, LPC1113FBD48/301 application, or LPC1113FBD48/301 equivalent, key selection considerations include its 42 GPIO count, lack of power profiles (LPC1100 series), dual SPI capability in LQFP48, and compatibility with standard ARM Cortex-M0 toolchains and debug interfaces.
Technical Context
The LPC1113FBD48/301 implements an ARM Cortex-M0 core with NVIC and Serial Wire Debug, executing instructions at up to 50 MHz using either internal 12 MHz RC oscillator (±1 %) or external crystal (1–25 MHz). Its clock system includes PLL, watchdog oscillator (9.4 kHz–2.3 MHz), and configurable clock output.
Peripheral integration includes a 10-bit ADC with up to 8 input channels (AD[7:0]), two SPI controllers with FIFO and multi-protocol support (SPI0/SPI1), full I²C-bus + Fast-mode Plus (1 Mbit/s), UART with fractional baud rate generation and RS-485/EIA-485 support, and four independent timers (two 32-bit, two 16-bit) with capture/match functionality.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1114FBD48/301 | 32 kB flash, same 8 kB SRAM, identical pinout and peripheral set. | Supports larger firmware images (e.g., BLE stack, advanced UI), but requires no PCB change. | Select when firmware growth exceeds 24 kB or future-proofing is required without layout revision. |
| LPC1113FBD48/302 | Same 24 kB flash / 8 kB SRAM, but adds power profiles and windowed watchdog timer (LPC1100L series). | Enables dynamic power optimization in battery-powered nodes; suitable for extended sleep modes. | Choose for energy-constrained applications where deep-sleep current and wake-up latency matter. |
Compared with LPC1114FBD48/301, the LPC1113FBD48/301 offers lower flash capacity but identical performance and I/O; compared with LPC1113FBD48/302, it lacks power profile support and windowed WDT-making it optimal for cost-driven, mains-powered designs where those features are unnecessary.

FAQ
What is the maximum operating frequency of the LPC1113FBD48/301?
The LPC1113FBD48/301 operates at a maximum CPU frequency of 50 MHz. This is achieved using the internal PLL driven by either the 12 MHz internal RC oscillator or an external crystal (1–25 MHz). The 50 MHz clock enables deterministic real-time execution for control algorithms and communication stacks without requiring high-frequency external crystals.
Does the LPC1113FBD48/301 support RS-485 communication?
Yes, the LPC1113FBD48/301 supports RS-485/EIA-485 communication via its UART peripheral. The UART includes hardware features such as fractional baud rate generation and internal FIFO, enabling reliable half-duplex differential communication over noisy industrial environments. External transceiver ICs (e.g., SN65HVD72) are required for physical layer implementation.
How many ADC channels does the LPC1113FBD48/301 have, and what is their resolution?
The LPC1113FBD48/301 integrates a 10-bit successive approximation ADC with up to eight input channels (AD[0:7]). On the LQFP48 package, all eight channels are accessible. This resolution supports accurate measurement of analog signals such as temperature, voltage, and current in industrial and appliance applications without requiring external precision ADCs.
Is the LPC1113FBD48/301 pin-compatible with other LPC111x LQFP48 variants?
Yes, the LPC1113FBD48/301 shares identical pinout and package (LQFP48) with other LPC111x LQFP48 variants including LPC1114FBD48/301 and LPC1115FBD48/303. However, feature availability (e.g., power profiles, windowed WDT, flash size) differs by suffix (/301 vs /302 vs /303), so firmware and configuration must align with the specific variant's capabilities.
What debug interface does the LPC1113FBD48/301 support?
The LPC1113FBD48/301 supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins. This two-pin interface enables full debug functionality-including breakpoints, watchpoints, memory inspection, and flash programming-using standard ARM-compliant tools like LPC-Link2, J-Link, or CMSIS-DAP debug probes.
