NXP Semiconductors LPC2114FBD64/01,15

Overview

LPC2114FBD64/01 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package, featuring 128 kB flash, 16 kB SRAM, four-channel 10-bit ADC (2.44 µs conversion), dual 32-bit timers with capture/compare, six PWM outputs, and dual UARTs with fractional baud rate generators. It operates at up to 60 MHz and targets industrial control, access systems, and embedded gateways.

For engineers reviewing the LPC2114FBD64/01 datasheet, LPC2114FBD64/01 pinout, LPC2114FBD64/01 application, or LPC2114FBD64/01 equivalent, key selection considerations include its 64-pin LQFP footprint, 1.8 V core / 3.3 V I/O dual supply, Fast GPIO capability (3.5× faster toggling), and support for ISP/IAP programming with CRP security levels.

Technical Context

The LPC2114FBD64/01 implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit performance with 16-bit code density-reducing firmware size by >30% with minimal speed penalty. Its 128-bit wide memory interface and accelerator architecture sustain full 60 MHz CPU operation.

It integrates a Vectored Interrupt Controller (VIC) supporting FIQ/IRQ prioritization, EmbeddedICE-RT for real-time debugging, and Embedded Trace Macrocell (ETM) for non-intrusive instruction tracing. Peripheral subsystems include two SPI interfaces (one shared with SSP), Fast I²C (400 kbit/s), and hardware handshake flow control on UART1.

FAQ

What is the maximum operating frequency of the LPC2114FBD64/01?

The LPC2114FBD64/01 supports a maximum CPU clock frequency of 60 MHz, achieved via its on-chip Phase-Locked Loop (PLL) with 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. The LPC2114FBD64/01 achieves this performance while maintaining compatibility with standard ARM7TDMI-S toolchains and debug infrastructure.

Does the LPC2114FBD64/01 support in-system programming (ISP)?

Yes, the LPC2114FBD64/01 supports In-System Programming (ISP) via its UART0 interface using the on-chip bootloader. Flash programming occurs at 1 ms per 512-byte line, with single-sector or full-chip erase taking 400 ms. ISP allows field firmware updates without removing the device from the PCB, and the LPC2114FBD64/01 retains full ISP functionality even when Code Read Protection (CRP) is disabled.

How many analog inputs does the LPC2114FBD64/01 ADC support?

The LPC2114FBD64/01 integrates a single 10-bit successive approximation ADC with four multiplexed analog input channels (AIN0–AIN3), mapped directly to pins P0[27]–P0[30]. Each channel has a dedicated result register to minimize interrupt overhead, and the ADC achieves a minimum conversion time of 2.44 µs-enabling over 400,000 samples per second in burst mode. The LPC2114FBD64/01 ADC operates over a 0–3 V input range and supports trigger sources including external pin transitions and timer match events.

Is the LPC2114FBD64/01 pin-compatible with other LPC21xx devices?

Yes, the LPC2114FBD64/01 is pin-compatible with LPC2124FBD64/01 and shares identical LQFP64 pinout, power domains, and peripheral mappings-including Fast GPIO, SSP, and enhanced UART features. However, it is not pin-compatible with earlier LPC210x series (e.g., LPC2106) due to differences in debug interface pin assignments and missing SSP/UART enhancements. The LPC2114FBD64/01 maintains full functional and mechanical compatibility within the /01 suffix family.

What debug interfaces are supported by the LPC2114FBD64/01?

The LPC2114FBD64/01 supports IEEE 1149.1 JTAG via pins P1[26]–P1[31] (RTCK, TDO, TDI, TCK, TMS, TRST) and EmbeddedICE-RT for real-time breakpoint/watchpoint debugging. It also includes an Embedded Trace Macrocell (ETM) for non-intrusive instruction tracing. Debug access remains available unless Code Read Protection (CRP) is enabled, which disables JTAG and ISP-requiring full flash erase to restore access. The LPC2114FBD64/01 supports both on-chip RealMonitor software and external debug probes.
