Overview
LPC11C24FBD48/301 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller with 32 kB flash, 8 kB SRAM, integrated C_CAN controller and on-chip high-speed CAN transceiver, operating up to 50 MHz - designed for industrial sensor networks and RS-485/EIA-485-based metering systems.
For engineers reviewing the LPC11C24FBD48/301 datasheet, LPC11C24FBD48/301 pinout, LPC11C24FBD48/301 application, or LPC11C24FBD48/301 equivalent, key selection criteria include its 36 GPIO count, 10-bit 8-channel ADC, Fast-mode Plus I²C (1 Mbit/s), dual SPI with SSP features, and integrated CAN transceiver eliminating external PHY requirements.
Technical Context
The LPC11C24FBD48/301 implements an ARM Cortex-M0 core with NVIC and Serial Wire Debug, paired with a programmable PLL enabling full 50 MHz operation from internal 12 MHz RC oscillator or external crystal (1–25 MHz). Its clock generation includes dedicated watchdog oscillator (7.8 kHz–1.8 MHz) and CLKOUT divider supporting system-level timing visibility.
Power management integrates a PMU supporting Sleep, Deep-sleep, and Deep power-down modes, with wake-up via 13 configurable GPIO pins and Brownout detection at four thresholds. The device uses a single 3.3 V supply (1.8–3.6 V range) and features 5 V-tolerant digital I/O with configurable pull-ups, hysteresis, and glitch filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC11C22FBD48/301 | Same package and pinout; 16 kB flash (vs. 32 kB); identical on-chip CAN transceiver and peripherals. | Suitable for simpler firmware or memory-constrained designs where 16 kB suffices for bootloader + application. | Select when flash budget is ≤16 kB and full 32 kB is unnecessary - reduces cost without sacrificing CAN integration or GPIO count. |
| STM32F042F6P6 | ARM Cortex-M0, 32 kB flash, 6 kB SRAM, no integrated CAN transceiver (requires external TJA1050), 48-pin LQFP package. | Requires external CAN PHY and additional passives; lacks RS-485 UART support and Fast-mode Plus I²C. | Choose only if existing design already uses STM32 toolchain and external CAN PHY is acceptable - adds BOM cost and layout complexity vs. LPC11C24FBD48/301. |
Compared with LPC11C22FBD48/301, the LPC11C24FBD48/301 doubles flash capacity for larger firmware or OTA update partitions; versus STM32F042F6P6, it delivers true single-chip CAN node capability with lower system-level component count and RS-485 readiness.

FAQ
Does the LPC11C24FBD48/301 require an external CAN transceiver?
No. The LPC11C24FBD48/301 integrates a high-speed CAN transceiver with dedicated CANH, CANL, STB, VDD_CAN, and VCC pins - enabling direct connection to the CAN bus without external PHY components. This eliminates BOM cost, board space, and signal integrity risks associated with discrete transceivers.
What is the maximum clock frequency supported by the LPC11C24FBD48/301?
The LPC11C24FBD48/301 supports CPU operation up to 50 MHz using its integrated PLL, which can be driven by either the internal 12 MHz RC oscillator (trimmed to ±1 %) or an external crystal (1–25 MHz range). This allows full performance without requiring a high-frequency crystal.
How many analog inputs does the LPC11C24FBD48/301 support?
The LPC11C24FBD48/301 includes a 10-bit ADC with multiplexing across 8 dedicated input channels (AD0–AD7), mapped to GPIO pins PIO0_11, PIO1_0–PIO1_3, PIO1_4, PIO1_10, and PIO1_11 - enabling simultaneous monitoring of multiple analog sensors in metering or industrial control applications.
Can the LPC11C24FBD48/301 perform firmware updates in the field?
Yes. The LPC11C24FBD48/301 supports In-System Programming (ISP) and In-Application Programming (IAP) via its built-in bootloader. Flash updates can be initiated over UART or C_CAN - allowing secure, remote firmware upgrades without physical access or external programming hardware.
What power-saving modes are available on the LPC11C24FBD48/301?
The LPC11C24FBD48/301 offers three reduced-power modes: Sleep, Deep-sleep, and Deep power-down. In Deep power-down, current drops to µA range, and wake-up can be triggered by any of 13 GPIO pins (including PIO1_4/WAKEUP) with 20 ns glitch filtering - ideal for battery-powered sensor nodes.
