Product details
Overview
LPC1113FBD48/302 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in LQFP48 package, operating up to 50 MHz with 24 kB flash, 8 kB SRAM, one UART with RS-485 support, one Fast-mode Plus I²C interface, two SPI controllers, four timers, and a 10-bit ADC-designed for cost-sensitive industrial control and smart sensor nodes.
For engineers reviewing the LPC1113FBD48/302 datasheet, LPC1113FBD48/302 pinout, LPC1113FBD48/302 application, or LPC1113FBD48/302 equivalent, key selection criteria include power profile support (LPC1100L series), 42 GPIO availability, LQFP48 thermal performance, and compatibility with legacy LPC11xx toolchains and boot ROM APIs.
Technical Context
The LPC1113FBD48/302 implements the ARM Cortex-M0 core with NVIC and Serial Wire Debug, paired with an integrated Power Management Unit enabling Sleep, Deep-sleep, and Deep power-down modes. Its clock system includes a 12 MHz ±1 % internal RC oscillator, crystal oscillator (1–25 MHz), and programmable watchdog oscillator (9.4 kHz–2.3 MHz).
Peripheral integration includes a windowed watchdog timer (WDT), configurable open-drain GPIO mode, high-current output (20 mA) on one pin, and high-current sink (20 mA) on two I²C pins-features specific to the LPC1100L series variant denoted by the "/302" suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M0, 32-bit RISC, supports Thumb-2 instruction set for compact code size vs. 8/16-bit MCUs. |
| Max Clock Frequency | 50 MHz - enables real-time response in motor control loops or sensor fusion at sub-20 µs interrupt latency. |
| Flash Memory | 24 kB - sufficient for bootloader + application firmware with room for field updates in metering or lighting systems. |

FAQ
What is the maximum operating frequency of the LPC1113FBD48/302?
The LPC1113FBD48/302 operates at a maximum CPU frequency of 50 MHz. This speed is achievable using either the internal 12 MHz ±1 % RC oscillator with PLL multiplication or an external crystal oscillator (1–25 MHz) directly driving the core. The 50 MHz limit is specified across the full industrial temperature range (−40 °C to +85 °C) and 1.8–3.6 V supply.
Does the LPC1113FBD48/302 support In-Application Programming (IAP)?
Yes, the LPC1113FBD48/302 supports In-Application Programming via its on-chip bootloader. Firmware updates can be performed over UART without halting real-time tasks, enabling field upgrades in deployed eMetering or lighting systems. IAP routines are accessible through documented ROM API calls and require no external debugger.
How many ADC channels does the LPC1113FBD48/302 provide, and what is their resolution?
The LPC1113FBD48/302 integrates a 10-bit successive-approximation ADC with up to eight input channels (AD[7:0]). All eight channels are physically available on the LQFP48 package. The ADC achieves ±2 LSB integral nonlinearity and supports programmable sampling rates up to 400 kS/s when using the internal 12 MHz clock source.
What debug interface does the LPC1113FBD48/302 use, and how many pins are required?
The LPC1113FBD48/302 uses Serial Wire Debug (SWD), requiring only two pins: SWDIO (bidirectional data) and SWCLK (clock). This two-pin interface replaces traditional JTAG, reducing PCB routing complexity and enabling debugging even in space-constrained layouts where the LPC1113FBD48/302 is used.
Is the LPC1113FBD48/302 pin-compatible with other LPC11xx LQFP48 variants?
Yes, the LPC1113FBD48/302 shares identical LQFP48 pinout and electrical characteristics with other LPC11xx LQFP48 devices including LPC1114FBD48/302 and LPC1113FBD48/301. Pin compatibility extends to power, ground, reset, clock, debug, and all peripheral signal assignments-enabling drop-in replacement within the same package family.
