Product details
Overview
LPC11E14FBD48/401 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in LQFP48 package, operating at up to 50 MHz CPU frequency with 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/Smart Card USART, four general-purpose timers, and 40 GPIO pins - deployed in industrial control systems requiring deterministic real-time response and low-power operation.
For engineers reviewing the LPC11E14FBD48/401 datasheet, LPC11E14FBD48/401 pinout, LPC11E14FBD48/401 application, or LPC11E14FBD48/401 equivalent, key selection criteria include its 40 GPIO count in LQFP48, support for synchronous USART mode and ISO 7816-3 smart card interface, integrated power management unit enabling Deep power-down wake-up via dedicated WAKEUP pin, and boot ROM-resident power profiles for rapid low-power configuration.
Technical Context
The LPC11E14FBD48/401 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 capability, 10 kB SRAM, and 4 kB EEPROM with byte-level erasure - all accessible via AHB/APB bus matrix with remappable interrupt vector table.
Clock generation combines a 1–25 MHz crystal oscillator, 12 MHz internal RC oscillator (IRC), programmable PLL, and dedicated watchdog oscillator (WDO). Power control features four reduced-power modes (Sleep, Deep-sleep, Power-down, Deep power-down), with wake-up from Deep power-down enabled only on PIO0_16/WAKEUP pin and supported by brownout detection across four thresholds.

FAQ
What is the maximum operating frequency of the LPC11E14FBD48/401?
The LPC11E14FBD48/401 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 LPC11E14FBD48/401 support in-application programming of EEPROM?
Yes, the LPC11E14FBD48/401 supports byte-erasable and byte-programmable EEPROM operations via In-Application Programming (IAP) using APIs located in the 16 kB boot ROM. This allows firmware to update calibration data or configuration parameters without halting execution or requiring external programming hardware.
How many GPIO pins does the LPC11E14FBD48/401 provide in the LQFP48 package?
The LPC11E14FBD48/401 provides 40 general-purpose I/O pins in the LQFP48 package, as confirmed in Table 2 of the datasheet. These include configurable pull-up/pull-down resistors, repeater mode, open-drain capability, and up to eight pins selectable as edge- or level-sensitive interrupt sources.
What is the function of the WAKEUP pin on the LPC11E14FBD48/401?
The WAKEUP pin on the LPC11E14FBD48/401 is PIO0_16, which serves as the sole wake-up source from Deep power-down mode. A LOW-going pulse as short as 50 ns on this pin exits Deep power-down; pulling it HIGH externally enters the mode. It includes a 20 ns glitch filter and requires no external circuitry beyond a pull-up resistor.
Does the LPC11E14FBD48/401 include hardware support for ISO 7816-3 smart card communication?
Yes, the LPC11E14FBD48/401 includes native hardware support for ISO 7816-3 asynchronous smart card interface within its USART peripheral. This includes automatic guard time insertion, character timing control, and T=0 protocol handling - eliminating the need for external smart card interface ICs in access control or payment terminal designs.
