It targets cost-sensitive industrial control and smart sensor nodes requiring extended temperature operation.
For engineers reviewing the LPC1113JBD48/303QL datasheet, LPC1113JBD48/303QL pinout, LPC1113JBD48/303QL application, or LPC1113JBD48/303QL equivalent, this page delivers verified specifications, validated pin functions for LQFP48, real-world use cases in metering and lighting, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The LPC1113JBD48/303QL implements the ARM Cortex-M0 core with NVIC and system tick timer, supporting Thumb-2 instruction set and low-latency interrupt handling. 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 CPU frequency scaling.
Power management includes Sleep, Deep-sleep, and Deep power-down modes managed by an integrated PMU, with wake-up capability via 13 GPIO pins. The LPC1100XL series variant adds windowed watchdog timer, configurable open-drain GPIO mode, and power profiles stored in boot ROM for runtime optimization.

FAQ
What is the maximum operating frequency of the LPC1113JBD48/303QL?
The LPC1113JBD48/303QL operates at a maximum CPU frequency of 50 MHz. This speed is achievable using the on-chip PLL driven by either the internal 12 MHz RC oscillator or an external crystal oscillator. The 50 MHz clock enables fast interrupt response and efficient execution of real-time control algorithms within the ARM Cortex-M0 core.
Does the LPC1113JBD48/303QL support hardware-based RS-485 communication?
Yes, the LPC1113JBD48/303QL UART includes built-in RS-485 support with driver enable control signals. This allows direct interfacing with RS-485 transceivers without external logic, simplifying industrial bus node design. The UART also features fractional baud rate generation and internal FIFO to ensure reliable half-duplex communication.
What is the ADC resolution and channel count on the LPC1113JBD48/303QL?
The LPC1113JBD48/303QL integrates a 10-bit successive approximation ADC with up to 8 input channels (AD0–AD7). All 8 channels are accessible in the LQFP48 package, enabling simultaneous sampling of multiple analog sensors such as temperature, voltage, and current in metering or motor control applications.
How does the windowed watchdog timer in the LPC1113JBD48/303QL improve system reliability?
The LPC1113JBD48/303QL includes a windowed watchdog timer (WWDT) that requires service within a defined time window-not just before timeout. This prevents false resets caused by premature servicing and detects both runaway code and stuck states, significantly improving fault tolerance in safety-critical applications like fire alarms and energy meters.
Is the LPC1113JBD48/303QL pin-compatible with other members of the LPC1100XL family in LQFP48 package?
Yes, the LPC1113JBD48/303QL is pin-compatible with all LPC1100XL series devices in LQFP48 package, including LPC1114JBD48/303 and LPC1115JBD48/303. Pin functions, power connections, and peripheral mappings are identical; only flash size and certain feature enablement (e.g., WWDT) differ - enabling scalable firmware reuse across variants.
