Product details
Overview
LPC11E12FBD48/201 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller operating at up to 50 MHz, featuring 16 kB flash, 6 kB SRAM, and 1 kB EEPROM. It integrates a 10-bit ADC (8-channel), two SSP interfaces, one Fast-mode Plus I²C-bus, one RS-485/UART with smart card support, four timers, and 40 GPIO pins - deployed in industrial control and handheld scanner applications.
For engineers reviewing the LPC11E12FBD48/201 datasheet, LPC11E12FBD48/201 pinout, LPC11E12FBD48/201 application, or LPC11E12FBD48/201 equivalent, key selection criteria include its LQFP48 package, 50 MHz CPU clock, 1 kB EEPROM byte-programmability, 40 GPIO with interrupt grouping, and dual SSP/I²C/USART peripheral concurrency for embedded edge-node designs.
Technical Context
The LPC11E12FBD48/201 implements an ARM Cortex-M0 core with NVIC supporting 24 vectored interrupts and programmable priority levels. Its memory subsystem includes 16 kB flash with ISP/IAP, 6 kB SRAM, and 1 kB byte-erasable EEPROM - all accessible via AHB/APB bus matrix with remappable interrupt vectors.
Peripherals are tightly integrated: the USART supports RS-485, synchronous mode, and ISO 7816-3 smart card interface; two SSP controllers provide FIFO-based SPI/Microwire compatibility; and the I²C-bus achieves 1 Mbit/s Fast-mode Plus with multi-address recognition and monitor mode - all synchronized to a flexible clock system including PLL, IRC, and watchdog oscillator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M0, 50 MHz max - enables deterministic real-time response with Thumb-2 instruction set and low code footprint vs. 8/16-bit MCUs. |
| Flash Memory | 16 kB - sufficient for firmware + bootloader; supports In-System Programming (ISP) and In-Application Programming (IAP). |
| SRAM | 6 kB - allocated for stack, heap, and real-time data buffers; mapped at 0x10000000 per memory map. |
| EEPROM | 1 kB - byte-erasable and byte-programmable; retains calibration data across power cycles without external storage. |
| ADC | 10-bit, 8-channel - multiplexed across GPIO pins PIO0_0–PIO0_7; supports single-shot and burst modes with 400 ksps max sample rate. |
| GPIO | 40 pins - configurable as inputs/outputs with pull-up/down, repeater, open-drain, and edge/level-sensitive interrupt capability. |
| Timers | Four: two 32-bit (CT32B0/1), two 16-bit (CT16B0/1) - deliver up to 13 match outputs and 8 capture inputs for PWM, input capture, and quadrature decoding. |
| Serial Interfaces | 1× USART (RS-485/smart card), 2× SSP (SPI/Microwire), 1× I²C (Fast-mode Plus, 1 Mbit/s) - enable concurrent sensor, actuator, and bus communication. |
Pinout & Package
Package: LQFP48 (7 × 7 × 1.4 mm, SOT313-2); 48-pin quad flat package with exposed thermal pad not present - suitable for cost-sensitive industrial PCBs with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET/PIO0_0 | Reset input / GPIO port 0 pin 0 | Active-low reset with 20 ns glitch filter; also selects JTAG vs. SWD debug mode during boot. |
| SWDIO/PIO0_15/AD4/CT32B1_MAT2 | SWD data I/O / ADC input 4 / timer match output | Primary debug interface pin; shares analog input and timer function - requires careful signal routing to avoid noise coupling into ADC. |
| 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 FM+ mode is configured in IOCON. |
| PIO0_18/RXD & PIO0_19/TXD | USART receive/transmit | Dedicated UART pins usable in ISP mode; support RS-485 half-duplex with external transceiver control via GPIO. |
| PIO0_22/AD6/CT16B1_MAT1/MISO1 | ADC input 6 / timer match / SSP1 MISO | Multi-function pin requiring software configuration; ADC use disables digital I/O and removes 5 V tolerance. |
| XTALIN & XTALOUT | Crytal oscillator inputs | Support 1–25 MHz crystal; internal oscillator (IRC) can substitute for reduced BOM count in non-precision timing applications. |
Key Features
| Feature | Design Value |
|---|---|
| ARM Cortex-M0 + NVIC | 24 vectored interrupts with hardware priority masking - reduces ISR latency and simplifies real-time task scheduling in resource-constrained systems. |
| Byte-programmable EEPROM | 1 kB on-chip EEPROM allows field-updatable calibration constants and device-specific parameters without external NV memory or wear-leveling firmware. |
| Power Management Unit (PMU) | Four low-power modes (Sleep, Deep-sleep, Power-down, Deep power-down) with wake-up via GPIO, watchdog, or reset - extends battery life in portable scanners and medical sensors. |
| Smart Card Interface (ISO 7816-3) | Integrated USART synchronous mode supports contact-based smart card protocols - eliminates need for external protocol controller in secure access terminals. |
| GPIO Interrupt Grouping | Two GPIO group interrupt modules detect programmable logic patterns across multiple pins - enables efficient status monitoring of multi-signal industrial I/O banks. |
| High-current GPIO drivers | 20 mA source on PIO0_7 (CTS), 20 mA sink on true open-drain pins (e.g., PIO0_4/5) - directly drives LEDs or small relays without external buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC11E13FBD48/301 | 24 kB flash, 8 kB SRAM, 2 kB EEPROM - larger memory footprint but identical LQFP48 pinout and peripheral set. | Suitable for applications requiring larger firmware (e.g., OTA update stack + encryption) or extended data logging buffers. | Select when firmware size exceeds 16 kB or EEPROM retention of >1 kB is required; no PCB changes needed. |
| LPC11U12FBD48/201 | Same package and core, but adds USB 2.0 device controller and enhanced ROM API - lacks EEPROM and has reduced SRAM (4 kB). | Better suited for USB-connected peripherals (e.g., HID devices), but unsuitable where EEPROM-based parameter storage is mandatory. | Choose for USB-native designs needing host enumeration; avoid if EEPROM or >4 kB SRAM is required. |
Compared with LPC11E13FBD48/301, the LPC11E12FBD48/201 trades memory capacity for lower cost and power; versus LPC11U12FBD48/201, it prioritizes non-volatile data retention over USB connectivity - making it optimal for battery-powered, field-calibrated edge nodes.

FAQ
What is the maximum operating frequency of the LPC11E12FBD48/201?
The LPC11E12FBD48/201 operates at a maximum CPU frequency of 50 MHz, achievable using either the internal 12 MHz IRC oscillator with PLL multiplication or an external crystal (1–25 MHz) fed into the system oscillator. This frequency is confirmed in the official NXP datasheet Rev. 1.1 and applies specifically to the LPC11E12FBD48/201 variant in LQFP48 package.
Does the LPC11E12FBD48/201 support in-application programming (IAP) for both flash and EEPROM?
Yes, the LPC11E12FBD48/201 supports In-Application Programming (IAP) for both its 16 kB flash and 1 kB EEPROM via the on-chip boot ROM API. The ROM provides standardized IAP routines enabling firmware updates and parameter storage without halting execution - a capability explicitly documented for this part number in Section 7.2 and 7.4 of the datasheet.

Yes, the LPC11E12FBD48/201 supports RS-485 communication through its dedicated USART peripheral, which includes hardware support for RS-485/9-bit mode and full modem handshake. Implementation requires external RS-485 transceiver connected to TXD/RXD pins and GPIO-controlled direction control - a configuration validated in NXP application notes AN10881 and the LPC11E1x datasheet Section 2.
What power supply voltage range and temperature grade does the LPC11E12FBD48/201 support?
The LPC11E12FBD48/201 operates from a single 3.3 V supply with allowable range of 1.8 V to 3.6 V, and is rated for industrial temperature range of −40 °C to +85 °C - specified in Section 2 "Features and benefits" and confirmed in Table 1 of the official NXP datasheet Rev. 1.1.
