Product details
Overview
LPC11D14FBD100/302 from NXP Semiconductors is a dual-chip ARM Cortex-M0 microcontroller integrating an LPC1114 MCU and PCF8576D LCD driver in a single 100-pin LQFP package. It delivers 50 MHz CPU operation, 32 kB flash/8 kB SRAM, and drives up to 40 segments × 4 backplanes for low-power LCD interfaces in embedded human-machine interfaces.
For engineers reviewing the LPC11D14FBD100/302 datasheet, LPC11D14FBD100/302 pinout, LPC11D14FBD100/302 application, or LPC11D14FBD100/302 equivalent, key selection criteria include integrated LCD drive capability, I²C-based display RAM auto-increment addressing, RS-485 UART support, and 42 GPIO with configurable pull-up/pull-down and interrupt capability.
Technical Context
The LPC11D14FBD100/302 implements a tightly coupled dual-die architecture: the LPC1114 MCU handles system control, real-time processing, and peripheral management via ARM Cortex-M0 core, while the PCF8576D LCD controller operates independently over dedicated I²C (LCD_SCL/LCD_SDA) and provides hardware-managed display RAM with auto-increment addressing and static/multiplexed drive modes.
Its clocking subsystem supports multiple sources - 12 MHz ±1 % internal RC oscillator, external crystal (1–25 MHz), and programmable watchdog oscillator (9.4 kHz–2.3 MHz) - with PLL enabling full 50 MHz CPU operation. Power management includes Sleep, Deep-sleep, and Deep power-down modes, with wake-up via dedicated pins and brownout detection at four thresholds.
Key Specifications

|---|---|
| CPU Core | ARM Cortex-M0, 50 MHz max - enables deterministic real-time execution with Thumb-2 instruction set and NVIC for low-latency interrupt handling. |
| Memory | 32 kB flash + 8 kB SRAM - sufficient for firmware with display logic, sensor drivers, and communication stacks without external memory. |
| LCD Drive Capability | 40 segments × 4 backplanes - supports common alphanumeric and segmented displays used in thermostats, white goods, and industrial HMI panels. |
| I/O & Peripherals | 42 GPIO, 1 UART (RS-485), 2 SPI, 1 Fast-mode Plus I²C, 10-bit ADC (8 channels), 4 timers - provides full system integration for sensor interfacing, serial comms, and timing-critical functions. |
| Package & Power | LQFP100 (14 × 14 × 1.4 mm), 1.8–3.6 V supply - standard surface-mount footprint compatible with automated assembly; single-rail operation simplifies power design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller-with-LCD-driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4, 48 MHz, 256 kB flash, 32 kB SRAM, no integrated LCD driver - requires external segment driver or graphical LCD controller. | Better for applications needing higher compute performance or USB connectivity; unsuitable where space-constrained 40-segment LCD drive is mandatory. | Select when migrating to Renesas ecosystem or requiring DSP instructions; not a drop-in replacement due to missing LCD hardware. |
| STM32L072KBU6 | ARM Cortex-M0+, 32 MHz, 128 kB flash, 20 kB SRAM, integrated LCD controller supporting up to 8×40 segments but no dedicated display RAM auto-increment addressing. | Supports larger displays and lower active current, but requires more software overhead for display updates and lacks hardware subaddressing. | Choose for extended battery life in ultra-low-power designs where display complexity exceeds 40 segments; verify LCD timing compatibility. |
Compared with RA4M1 and STM32L072KBU6, the LPC11D14FBD100/302 uniquely combines fixed-function LCD drive with minimal software overhead, making it optimal for cost-sensitive, space-constrained HMI applications requiring exactly 40-segment × 4-backplane support without external components.

FAQ
What is the primary function of the LPC11D14FBD100/302?
The LPC11D14FBD100/302 is a dual-die microcontroller integrating an ARM Cortex-M0 core (LPC1114) and a PCF8576D LCD driver in one LQFP100 package. Its primary function is to serve as a complete system-on-package solution for embedded devices requiring local segmented LCD display, real-time control, and industrial communication interfaces - all without external display driver components.
Does the LPC11D14FBD100/302 support RS-485 communication?
Yes, the LPC11D14FBD100/302 includes one UART with built-in RS-485/EIA-485 support, including fractional baud rate generation and internal FIFO. This allows direct connection to RS-485 transceivers for robust multi-drop communication in noisy industrial environments - a confirmed feature documented in the official NXP datasheet Rev. 2.
How many LCD segments and backplanes does the LPC11D14FBD100/302 support?
The LPC11D14FBD100/302 supports up to 40 LCD segments and 4 backplanes via its integrated PCF8576D controller. This enables configurations such as 1:4 multiplex (40 segments × 4 backplanes), 1:2 multiplex (80 segments × 2 backplanes), or static drive (40 segments × 1 backplane), as verified in Section 7.2.2 and Table 4 of the NXP datasheet.
What debug interface does the LPC11D14FBD100/302 provide?
The LPC11D14FBD100/302 provides Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins (mapped to PIO1_3 and PIO0_10). This two-pin debug interface supports full run-control, memory access, and real-time variable inspection - eliminating the need for legacy JTAG headers and reducing PCB routing complexity.
Can the LPC11D14FBD100/302 operate from a single 3.3 V supply?
Yes, the LPC11D14FBD100/302 operates from a single 1.8 V to 3.6 V supply on VDD, with VDD also serving as the ADC reference voltage. The LCD section uses separate supplies - VDD(LCD) (1.8–5.5 V) and VLCD - allowing independent bias voltage selection for optimal LCD contrast without affecting core logic operation.
