Product details
Overview
LPC11C12FBD48/301 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller designed for cost-sensitive industrial and sensor network applications, featuring 16 kB flash, 8 kB SRAM, one C_CAN controller, RS-485 UART, two SPI interfaces, 10-bit ADC with 8 channels, and 40 GPIO pins in a 48-pin LQFP package.
For engineers reviewing the LPC11C12FBD48/301 datasheet, LPC11C12FBD48/301 pinout, LPC11C12FBD48/301 application, or LPC11C12FBD48/301 equivalent, key selection considerations include its C_CAN interface without integrated transceiver, 50 MHz CPU clock, Fast-mode Plus I²C (1 Mbit/s), and Deep power-down wake-up capability via dedicated GPIO pins.
Technical Context
The LPC11C12FBD48/301 implements an ARM Cortex-M0 core with Nested Vectored Interrupt Controller (NVIC) and Serial Wire Debug, operating at up to 50 MHz using either internal 12 MHz RC oscillator (±1 %) or external crystal (1–25 MHz). Its clock system includes PLL, programmable watchdog oscillator (7.8 kHz–1.8 MHz), and configurable clock output.
Peripheral integration includes a C_CAN controller compliant with CAN 2.0B, UART with RS-485 support and fractional baud rate generation, two SSP-capable SPI controllers with FIFO, Fast-mode Plus I²C (1 Mbit/s), four general-purpose timers (including 32-bit and 16-bit variants), and a 10-bit ADC with multiplexed inputs across eight pins.
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 control and protocol handling (e.g., CAN, RS-485) without external clock source. |
| Memory | 16 kB on-chip flash + 8 kB SRAM - sufficient for firmware with CANopen stack and sensor data processing. |
| Analog Interface | 10-bit ADC with 8 input channels - supports direct connection of temperature, voltage, or current sensors. |
| Digital Interfaces | 1× C_CAN controller, 1× RS-485 UART, 2× SPI (SSP), 1× Fast-mode Plus I²C (1 Mbit/s) - enables multi-protocol industrial fieldbus connectivity. |
| GPIO | 40 general-purpose I/O pins with configurable pull-up/down, 10 ns glitch filtering, and interrupt capability on edge/level - suitable for mixed-signal board-level interfacing. |
| Power Management | Three low-power modes (Sleep, Deep-sleep, Deep power-down); wake-up from Deep power-down via 13 GPIO pins - extends battery life in remote sensor nodes. |
Pinout & Package
Package: LQFP48 (plastic low profile quad flat package; 48 leads; body 7 × 7 × 1.4 mm, SOT313-2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET/PIO0_0 | Reset input / GPIO | External reset with 20 ns glitch filter; LOW pulse ≥50 ns triggers full device reset and restarts execution at address 0. |
| CAN_RXD (Pin 19) | CAN receive input | CMOS-level digital input for C_CAN controller; requires external transceiver (LPC11C12 lacks on-chip CAN PHY). |
| CAN_TXD (Pin 20) | CAN transmit output | CMOS-level digital output from C_CAN controller; must be connected to external CAN transceiver TXD pin. |
| PIO0_4/SCL & PIO0_5/SDA | I²C bus clock/data | Open-drain pins supporting Fast-mode Plus (1 Mbit/s); high-current sink enabled only when Fast-mode Plus selected in IOCONFIG. |
| PIO1_4/AD5/WAKEUP | ADC input / wake-up trigger | Analog input channel 5; also functions as Deep power-down wake-up pin - LOW-going pulse ≥50 ns exits low-power state. |
| XTALIN / XTALOUT | Clock oscillator interface | Supports 1–25 MHz crystal; XTALIN accepts ≤1.8 V input; XTALOUT is buffered output for external load capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programming (ISP) | Flash reprogramming via UART or C_CAN interface - eliminates need for external programmer in field updates. |
| Integrated PMU | Hardware-managed Sleep, Deep-sleep, and Deep power-down modes with configurable wake sources - reduces average current to µA range. |
| High-Current I/O Drivers | 20 mA output on PIO0_7; 20 mA sink on I²C pins in Fast-mode Plus - drives LEDs or small loads directly without external buffers. |
| Multi-Protocol Serial Peripherals | UART with RS-485 support, dual SPI with SSP features, and Fast-mode Plus I²C - simplifies communication with legacy and modern industrial peripherals. |
| Dedicated CAN Controller | C_CAN module compliant with CAN 2.0B, including CANopen drivers in ROM - accelerates development of CAN-based control networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC11C14FBD48/301 | 32 kB flash (vs. 16 kB), same 8 kB SRAM, identical peripherals and pinout. | Better suited for applications requiring larger firmware (e.g., OTA update capability, extended protocol stacks). | Select when firmware size exceeds 16 kB or future scalability is required; drop-in replacement with no PCB changes. |
| LPC11U12FBD48/301 | USB 2.0 device controller (no C_CAN), same Cortex-M0 core, 16 kB flash, 8 kB SRAM, 40 GPIO. | Targets USB-connected peripherals (e.g., HID devices, PC interface adapters) instead of CAN/RS-485 industrial networks. | Choose for USB-centric designs; not suitable for CAN-based systems due to missing C_CAN controller. |
Compared with LPC11C14FBD48/301, the LPC11C12FBD48/301 trades flash capacity for lower cost in fixed-function deployments; versus LPC11U12FBD48/301, it prioritizes industrial bus support over USB, making it optimal for CAN/RS-485 field equipment where protocol compatibility is non-negotiable.

FAQ
Does the LPC11C12FBD48/301 include an integrated CAN transceiver?
No, the LPC11C12FBD48/301 contains only the C_CAN controller logic and does not integrate a physical CAN transceiver. It requires an external CAN transceiver (e.g., TJA1042T) connected to CAN_RXD and CAN_TXD pins. This differs from LPC11C22/C24 variants which include an on-chip high-speed CAN transceiver.
What is the maximum operating frequency of the LPC11C12FBD48/301?
The LPC11C12FBD48/301 operates at a maximum CPU frequency of 50 MHz. This is achieved using the on-chip PLL driven by either the internal 12 MHz RC oscillator (trimmed to ±1 %) or an external crystal (1–25 MHz), enabling deterministic real-time performance for industrial protocols.
How many analog-to-digital converter channels does the LPC11C12FBD48/301 support?
The LPC11C12FBD48/301 integrates a 10-bit ADC with multiplexed inputs across eight pins (AD0–AD7), providing eight single-ended analog input channels. These are mapped to GPIO pins PIO0_11, PIO1_0–PIO1_3, PIO1_4–PIO1_5, PIO1_10, and PIO1_11 per the datasheet pin description table.
Can the LPC11C12FBD48/301 enter ultra-low-power states, and how is wake-up managed?
Yes, the LPC11C12FBD48/301 supports Deep power-down mode with typical current consumption below 1 µA. Wake-up is triggered by a LOW-going pulse ≥50 ns on any of 13 designated GPIO pins (including PIO1_4/WAKEUP), allowing flexible event-driven recovery without external circuitry.
Is the LPC11C12FBD48/301 pin-compatible with other members of the LPC11Cx2/Cx4 family?
Yes, the LPC11C12FBD48/301 shares the same 48-pin LQFP package and pinout with LPC11C14FBD48/301, LPC11C22FBD48/301, and LPC11C24FBD48/301. However, functional differences exist - notably, only LPC11C22/C24 include on-chip CAN transceivers, and LPC11C14/C24 feature 32 kB flash.
