For engineers reviewing the LPC2114FBD64,151 datasheet, LPC2114FBD64,151 pinout, LPC2114FBD64,151 application, or LPC2114FBD64,151 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and two confirmed alternative parts for embedded control designs requiring 60 MHz operation, 5 V-tolerant GPIO, and ISP/IAP capability.
Technical Context
The LPC2114FBD64,151 implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit performance at 60 MHz via a 128-bit wide memory interface and accelerator architecture. It integrates an EmbeddedICE-RT debug interface and Embedded Trace Macrocell (ETM) for non-intrusive real-time instruction tracing.
Its peripheral subsystem includes two UARTs with hardware handshake (RTS/CTS/DSR/DTR/DCD/RI), buffered SSP supporting SPI/SSI/Microwire, Fast I/O registers enabling 3.5× faster GPIO toggling than legacy LPC2000, and a 10-bit ADC with dedicated result registers per channel to minimize interrupt latency.

FAQ
What is the maximum operating frequency of the LPC2114FBD64,151?
The LPC2114FBD64,151 achieves a maximum CPU clock frequency of 60 MHz using its on-chip Phase-Locked Loop (PLL), which has a 100 µs settling time. This frequency is sustained by the 128-bit wide memory interface and accelerator architecture, enabling full-speed 32-bit code execution without wait states.
Does the LPC2114FBD64,151 support in-system programming (ISP)?
Yes, the LPC2114FBD64,151 supports In-System Programming via its UART0 interface using the on-chip bootloader. Flash programming takes 1 ms per 512-byte line, and sector or full-chip erase completes in 400 ms - enabling field firmware updates without removing the device from the PCB.
How many analog inputs does the LPC2114FBD64,151 ADC support?
The LPC2114FBD64,151 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], P0[30]) and supported by individual result registers to reduce interrupt service overhead.
Is the LPC2114FBD64,151 pin-compatible with other LPC21xx devices?
Yes, the LPC2114FBD64,151 shares identical pin configuration and LQFP64 package (SOT314-2) with LPC2124FBD64,151 and LPC2106FBD64,151. However, peripheral enablement (e.g., Fast GPIO, SSP, enhanced UART) and memory sizes differ - requiring firmware validation despite mechanical compatibility.
What power supply voltages does the LPC2114FBD64,151 require?
The LPC2114FBD64,151 requires two independent supplies: VDD(1V8) at 1.65–1.95 V for the ARM7TDMI-S core and analog circuitry, and VDD(3V3) at 3.0–3.6 V for I/O pads - which are 5 V tolerant when configured as digital inputs/outputs. Separate analog supplies (VDDA(1V8), VDDA(3V3), VSSA, VSSA(PLL)) must be isolated for ADC/PLL accuracy.
