Product details
Overview
LPC11E14FBD64/401 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller operating at up to 50 MHz, featuring 32 kB flash, 10 kB SRAM, and 4 kB byte-erasable 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 counter/timers, and up to 54 GPIO pins - deployed in industrial control and medical handheld devices requiring deterministic real-time response and low-power operation.
For engineers reviewing the LPC11E14FBD64/401 datasheet, LPC11E14FBD64/401 pinout, LPC11E14FBD64/401 application, or LPC11E14FBD64/401 equivalent, key selection criteria include its LQFP64 package with full 54-GPIO access, dedicated WAKEUP pin for Deep power-down recovery, 5 V-tolerant digital I/O with configurable pull-ups, and on-chip boot ROM containing power profiles and integer division routines.
Technical Context
The LPC11E14FBD64/401 implements an ARM Cortex-M0 core with NVIC supporting 24 vectored interrupts and non-maskable interrupt (NMI) routing from multiple sources. Its memory subsystem includes 32 kB flash with ISP/IAP, 10 kB SRAM, and 4 kB EEPROM - all accessible via AHB/APB bus matrix with remappable interrupt vectors.
Clock generation combines a 1–25 MHz crystal oscillator, 12 MHz internal RC oscillator, programmable PLL, and dedicated WatchDog Oscillator (WDO). Power management includes four low-power modes (Sleep, Deep-sleep, Power-down, Deep power-down), with wake-up via GPIO, watchdog, or the dedicated WAKEUP pin (PIO0_16).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M0, 32-bit RISC, up to 50 MHz - enables deterministic real-time execution with Thumb-2 instruction set and low code footprint vs. 8/16-bit MCUs. |
| Memory | 32 kB flash (ISP/IAP), 10 kB SRAM, 4 kB EEPROM (byte-erasable) - supports field firmware updates and persistent data storage without external components. |
| Analog Interface | 10-bit ADC with 8 input channels (AD0–AD7) - provides sufficient resolution for sensor interfacing in medical and industrial monitoring. |
| Digital Peripherals | Two SSP controllers (FIFO, multi-protocol), one Fast-mode Plus I²C (1 Mbit/s), one USART with RS-485/ISO 7816 smart card mode - enables robust communication in noisy industrial environments. |
| GPIO & Timers | 54 general-purpose I/O pins (5 V tolerant, configurable pull-up/down/open-drain); four timers including CT32B0/CT32B1 (32-bit) and CT16B0/CT16B1 (16-bit) with match/capture - supports complex I/O sequencing and precise timing control. |
| Power & Packaging | Single 3.3 V supply (1.8–3.6 V), −40 °C to +85 °C operation, LQFP64 (10 × 10 × 1.4 mm) - ensures compatibility with industrial-grade PCB layouts and thermal constraints. |
Pinout & Package
LPC11E14FBD64/401 is housed in a plastic low-profile quad flat package (LQFP64) with 64 leads, body size 10 × 10 × 1.4 mm (SOT314-2), exposing all 54 GPIOs plus dedicated debug, clock, reset, and power terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET/PIO0_0 | Reset input / GPIO port 0 pin 0 | External reset with 20 ns glitch filter; also selects JTAG vs. SWD debug mode during power-up. |
| SWDIO/PIO0_15/AD4/CT32B1_MAT2 | SWD debug I/O / ADC input 4 / timer match output | Shared pin enables in-circuit debugging, analog sensing, and PWM generation - requires careful multiplexing in firmware. |
| PIO0_16/AD5/CT32B1_MAT3/WAKEUP | ADC input 5 / timer match output 3 / Deep power-down wake pin | Dedicated wake source: LOW pulse ≥50 ns exits Deep power-down; must be externally pulled HIGH to enter that mode. |
| XTALIN / XTALOUT | Crytal oscillator input / output | Supports 1–25 MHz crystal; internal oscillator can substitute if external crystal omitted - affects clock accuracy and jitter. |
| VDD / VSS | Power supply / ground | Four VDD and four VSS pins distributed across package corners - reduces IR drop and improves noise immunity in high-speed digital operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC11U14FBD64/401 | Same package and pinout; adds USB 2.0 device controller and enhanced ROM API (USB stack), but reduces EEPROM to 2 kB. | Better suited for USB-connected peripherals; less suitable where persistent EEPROM storage >2 kB is required. | Select LPC11U14FBD64/401 only when native USB device functionality is mandatory and EEPROM budget allows reduction. |
| STM32F072RBT6 | LQFP64, Cortex-M0+, 48 MHz, 128 kB flash, 16 kB RAM, no EEPROM, integrated USB, different peripheral set (e.g., no WWDT, different ADC resolution). | Higher flash/RAM for complex firmware; lacks on-chip EEPROM - requires external serial EEPROM for parameter storage. | Choose STM32F072RBT6 when USB host/device capability and larger memory are priorities, and external EEPROM is acceptable. |
Compared with LPC11U14FBD64/401 and STM32F072RBT6, the LPC11E14FBD64/401 uniquely balances 4 kB on-chip EEPROM, 54 GPIOs, and industrial temperature range without USB overhead - making it optimal for cost-sensitive, EEPROM-dependent embedded control where USB is unnecessary.

FAQ
What is the maximum operating frequency of the LPC11E14FBD64/401?
The LPC11E14FBD64/401 operates at a maximum CPU frequency of 50 MHz, achievable using either the internal 12 MHz IRC oscillator with PLL multiplication or an external 1–25 MHz crystal oscillator. This frequency is fully supported across the specified industrial temperature range (−40 °C to +85 °C) and 1.8–3.6 V supply voltage.
Does the LPC11E14FBD64/401 include on-chip EEPROM, and what are its programming characteristics?
Yes, the LPC11E14FBD64/401 integrates 4 kB of on-chip EEPROM that is byte-erasable and byte-programmable. Programming is performed via In-Application Programming (IAP) calls from the boot ROM, requiring no external high-voltage supply. The EEPROM is rated for ≥100,000 write cycles and retains data for 20 years at 85 °C.
How many GPIO pins does the LPC11E14FBD64/401 provide, and are they 5 V tolerant?
The LPC11E14FBD64/401 provides up to 54 general-purpose I/O pins in its LQFP64 package. All GPIO pins - except I²C-bus pins PIO0_4 (SCL) and PIO0_5 (SDA) - are 5 V tolerant when powered from a 3.3 V supply, enabling direct interfacing with 5 V logic without external level shifters.
What debug interfaces are supported by the LPC11E14FBD64/401?
The LPC11E14FBD64/401 supports both Serial Wire Debug (SWD) and standard JTAG interfaces. SWD uses SWCLK and SWDIO (shared with PIO0_10 and PIO0_15), while JTAG uses TDI, TDO, TMS, TRST, and TCK (SWCLK). Debug selection is determined by the RESET pin state during power-up.
Can the LPC11E14FBD64/401 wake from Deep power-down mode, and how is this implemented?
Yes, the LPC11E14FBD64/401 can wake from Deep power-down mode exclusively via the dedicated WAKEUP pin (PIO0_16). An external LOW-going pulse ≥50 ns on this pin exits Deep power-down. To enter Deep power-down, PIO0_16 must be held HIGH externally - a hardware requirement confirmed in the official NXP datasheet Rev. 1.1.
