Product details
Overview
LPC2124FBD64,151 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller in LQFP64 package, featuring 256 kB flash, 16 kB SRAM, four-channel 10-bit ADC (2.44 µs conversion), dual 32-bit timers with capture/compare, six PWM outputs, RTC, and watchdog. It operates at up to 60 MHz with 1.8 V core and 3.3 V I/O supplies, targeting industrial control, access systems, and embedded gateways.
For engineers reviewing the LPC2124FBD64,151 datasheet, LPC2124FBD64,151 pinout, LPC2124FBD64,151 application, or LPC2124FBD64,151 equivalent, key selection considerations include flash size (256 kB vs. 128 kB in LPC2114), Fast GPIO timing, SSP support, and /01 suffix–enabled features including fractional UART baud rate generation, hardware auto-CTS/RTS, and dedicated ADC result registers.
Technical Context
The LPC2124FBD64,151 implements an ARM7TDMI-S RISC core with Thumb instruction set for code density optimization, coupled with a 128-bit wide memory interface and accelerator architecture enabling full 60 MHz execution speed. Its memory map includes remappable interrupt vectors and boot block re-mapping from flash.
Peripheral integration centers on AMBA AHB/APB architecture: AHB connects flash, RAM, and VIC; APB bridges UART0/1, I²C, SPI0/1, SSP, ADC, timers, and PWM. The Vectored Interrupt Controller supports 16 prioritized IRQ channels, FIQ, and non-vectored IRQs, with peripheral-specific interrupt flags mapped to VIC channels 0–18.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM7TDMI-S 32-bit RISC processor with Thumb mode; enables compact firmware and deterministic real-time response. |
| Max Clock Speed | 60 MHz via on-chip PLL (100 µs settling); delivers 60 MIPS performance without external clock synthesis. |
| Flash Memory | 256 kB ISP/IAP flash; supports in-system programming and in-application updates with 1 ms/512 B write time. |
| SRAM | 16 kB on-chip static RAM; accessible as 8/16/32-bit with zero-wait-state operation at full CPU speed. |
| ADC | Four-channel 10-bit successive approximation ADC; 2.44 µs conversion time, 5 V-tolerant pins in GPIO mode. |
| Timers & PWM | Two 32-bit timers (4 capture + 4 compare each) + six-output PWM unit; supports motor control and precise event timing. |
| Serial Interfaces | Two UARTs (16C550-compatible, fractional baud rate), Fast I²C (400 kbit/s), two SPIs, and SSP (SPI/SSI/Microwire). |
| I/O & Power | 46 total GPIO pins (5 V tolerant), nine external interrupt inputs; dual supply: 1.8 V ±0.15 V core, 3.3 V ±10 % I/O. |
Pinout & Package
Package: LQFP64 (SOT314-2), 10 × 10 × 1.4 mm, lead pitch 0.5 mm, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]/TXD0/PWM1 | UART0 transmit / PWM output | Primary serial debug channel or motor/servo control signal; shared function requires Pin Connect Block configuration. |
| P0[27]/AIN0/CAP0[1]/MAT0[1] | ADC input 0 / Timer0 capture / match | Analog sensor input with simultaneous timer-triggered sampling or edge-capture timing; no external mux needed. |
| P1[27]/TDO | JTAG test data output | Required for boundary scan and debug visibility; driven during JTAG TAP controller shift-DR state. |
| VDD(1V8) | Core power supply | Must be decoupled locally with ≥10 µF ceramic + 100 nF; noise on this rail directly impacts CPU stability and PLL jitter. |
| RESET | Active-low asynchronous reset | TTL-compatible with hysteresis; low pulse ≥100 ns forces full hardware reset and vector fetch from address 0x00000000. |
Key Features
| Feature | Design Value |
|---|---|
| Fast GPIO Registers | Relocated to ARM Local Bus; enables 3.5× faster port toggling than legacy LPC2000, critical for bit-banged protocols. |
| Dedicated ADC Result Registers | One per channel; eliminates read-modify-write overhead in ISR, reducing latency for high-frequency sampling loops. |
| Fractional UART Baud Rate Generator | Supports exact standard rates (e.g., 115200 Bd) from any crystal ≥2 MHz; removes need for custom crystal frequencies. |
| Embedded Trace Macrocell (ETM) | Non-intrusive real-time instruction trace; enables cycle-accurate profiling and complex bug reproduction without halting execution. |
| Code Read Protection (CRP) | Three security levels via bootloader; disables JTAG/ISP access to flash/RAM while permitting full ISP erase commands for field recovery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2114FBD64/01 | 128 kB flash, identical peripherals and pinout; lacks /01 suffix enhancements in some early revisions. | Suitable for cost-sensitive designs with firmware <128 kB; not recommended when >128 kB code space or SSP is required. | Select only if flash budget permits and SSP/Fast GPIO are unused. |
| LPC2138FBD64 | 512 kB flash, USB 2.0 device controller, enhanced ADC (eight channels), same core and package. | Enables USB HID/DFU firmware updates and higher-channel sensor aggregation; requires USB PHY and layout changes. | Choose when USB connectivity or >256 kB flash is mandatory; not drop-in compatible due to USB pin allocation. |
Compared with LPC2114FBD64/01, the LPC2124FBD64,151 offers double flash capacity and guaranteed /01 feature set; versus LPC2138FBD64, it trades USB and extra ADC channels for lower BOM cost and simpler layout-ideal for non-USB industrial gateways.

FAQ
What is the maximum operating frequency of the LPC2124FBD64,151?
The LPC2124FBD64,151 achieves a maximum CPU clock frequency of 60 MHz using its on-chip PLL with 100 µs settling time. This frequency is sustained across the full −40 °C to +85 °C industrial temperature range when powered by 1.8 V ±0.15 V core supply and properly decoupled. The 128-bit memory interface and accelerator enable zero-wait-state 32-bit code execution at this rate.
Does the LPC2124FBD64,151 support in-system programming (ISP)?
Yes, the LPC2124FBD64,151 supports full In-System Programming via its UART0 interface using the on-chip bootloader. Flash programming takes 1 ms per 512 B line, and sector or full-chip erase completes in 400 ms. ISP functionality remains available even with Code Read Protection enabled, though JTAG access is disabled when CRP is active.
How many analog inputs does the LPC2124FBD64,151 ADC support?
The LPC2124FBD64,151 integrates a single 10-bit successive approximation ADC with four multiplexed analog input channels (AIN0–AIN3), each mapped to dedicated pins P0[27], P0[28], P0[29], and P0[30]. Each channel has its own result register to minimize interrupt service routine overhead during high-speed sampling.
Is the LPC2124FBD64,151 pin-compatible with the LPC2114FBD64/01?
Yes, the LPC2124FBD64,151 is fully pin-compatible with the LPC2114FBD64/01 in the LQFP64 package. Both share identical pin configuration, electrical characteristics, and peripheral mapping. The primary functional difference lies in flash capacity (256 kB vs. 128 kB) and guaranteed inclusion of /01 suffix features such as fractional UART baud rate generation and dedicated ADC result registers.
What debug interfaces are available on the LPC2124FBD64,151?
The LPC2124FBD64,151 provides JTAG (IEEE 1149.1) via pins P1[26–31] for boundary scan and ICE debugging, EmbeddedICE-RT for breakpoints/watchpoints, and Embedded Trace Macrocell (ETM) for non-intrusive real-time instruction tracing. Debug access remains functional unless Code Read Protection (CRP) is enabled, which disables JTAG and ISP access to memory.
