FAQ

What is the maximum operating frequency of the LPC1113FBD48/302EL?

The LPC1113FBD48/302EL operates at a maximum CPU frequency of 50 MHz. This speed is achievable using either the internal 12 MHz RC oscillator (trimmed to ±1 % accuracy) or an external crystal oscillator (1–25 MHz) with PLL multiplication. The 50 MHz clock enables deterministic real-time response in control loops and communication protocols without external clock synthesis.

Does the LPC1113FBD48/302EL support in-system programming (ISP)?

Yes, the LPC1113FBD48/302EL supports In-System Programming (ISP) via its built-in bootloader, accessible through UART using standard ISP commands. This allows firmware updates in the field or during production without requiring a dedicated debugger. The bootloader resides in protected ROM and remains functional even after user flash programming, ensuring reliable recovery paths.

How many ADC channels does the LPC1113FBD48/302EL provide, and what is their resolution?

The LPC1113FBD48/302EL integrates a single 10-bit successive-approximation ADC with input multiplexing across up to eight pins (AD[7:0]). All eight channels are available in the LQFP48 package, enabling concurrent monitoring of multiple analog sensors - such as thermistors, light-dependent resistors, or voltage dividers - with 1024 discrete quantization levels per channel.

Is the LPC1113FBD48/302EL pin-compatible with other LPC111x LQFP48 variants?

Yes, the LPC1113FBD48/302EL shares identical pinout and package dimensions with all LQFP48-packaged LPC111x devices (e.g., LPC1114FBD48/302, LPC1115FBD48/303). Signal mapping, power, ground, and debug pins align across the family, enabling drop-in replacement for memory or feature upgrades - provided software accounts for differences in flash size, peripheral enablement, and power profile availability.

What power-saving features are implemented in the LPC1113FBD48/302EL?

The LPC1113FBD48/302EL implements three reduced-power modes: Sleep (CPU halted, peripherals active), Deep-sleep (CPU and most clocks stopped, SRAM retained), and Deep power-down (full retention loss except for reset logic). It also features a Power Management Unit (PMU), programmable brownout detection, and wake-up from Deep-sleep on up to 13 GPIO pins - delivering sub-1 µA standby current in optimized configurations.
