Product details
Overview
LPC2132FBD64/01EL from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package, featuring 64 kB flash, 16 kB SRAM, one 10-bit 8-channel ADC, one 10-bit DAC (AOUT), and dual UARTs with hardware flow control - deployed in industrial control systems requiring analog I/O, real-time interrupt response, and compact footprint.
For engineers reviewing the LPC2132FBD64/01EL datasheet, LPC2132FBD64/01EL pinout, LPC2132FBD64/01EL application, or LPC2132FBD64/01EL equivalent, key selection criteria include its 60 MHz CPU clock, 5 V-tolerant GPIO (47 pins), fast GPIO toggle capability (3.5× original), dedicated ADC result registers, and fractional baud rate generation for UART0/UART1.
Technical Context
The LPC2132FBD64/01EL implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit performance at reduced code size (up to 30 % smaller vs. ARM mode). Its memory subsystem uses a 128-bit wide interface and accelerator architecture to sustain full 60 MHz operation from on-chip flash.
Peripheral integration includes two 32-bit timers with capture/compare channels, PWM unit (6 outputs), RTC with independent 32 kHz clock and VBAT supply, and dual Fast I²C-bus interfaces (400 kbit/s). All serial interfaces - UART0/1, SPI, SSP, I²C0/1 - are APB-connected with configurable FIFO buffering and variable data length handling.

FAQ
What is the maximum operating frequency of the LPC2132FBD64/01EL?
The LPC2132FBD64/01EL achieves a maximum CPU clock of 60 MHz using its programmable on-chip PLL, which settles in 100 µs. This frequency is sustained via a 128-bit wide memory interface and accelerator architecture - enabling full-speed 32-bit code execution from flash without wait states. The PLL accepts input clocks from 1 MHz to 30 MHz crystals or up to 50 MHz external oscillators.
Does the LPC2132FBD64/01EL include a DAC, and how is it accessed?
Yes, the LPC2132FBD64/01EL includes a single 10-bit DAC with output on pin P0.25 (labeled AOUT). This analog output is active only when the DAC function is enabled in software; the digital I/O function of P0.25 is disabled during DAC operation. The DAC reference is tied to VREF, which must be isolated from digital noise for optimal linearity.
How many external interrupt pins does the LPC2132FBD64/01EL support, and what triggering modes are available?
The LPC2132FBD64/01EL supports up to nine external interrupt pins (EINT0–EINT3 plus five additional GPIO-configurable interrupts), each configurable for edge-sensitive (rising/falling/both) or level-sensitive (high/low) triggering. This flexibility allows direct interfacing with pushbuttons, limit switches, and safety interlock signals without external debouncing circuitry.
Is the LPC2132FBD64/01EL pin-compatible with other members of the LPC213x family?
Yes - the LPC2132FBD64/01EL shares identical LQFP64 pinout and electrical characteristics with LPC2131FBD64/01, LPC2134FBD64/01, LPC2136FBD64/01, and LPC2138FBD64/01. Firmware and PCB designs can be reused across these variants, with differentiation limited to flash/SRAM size, ADC count, and DAC presence - all managed via software configuration.
What debug and trace capabilities does the LPC2132FBD64/01EL provide?
The LPC2132FBD64/01EL integrates EmbeddedICE RT for real-time JTAG debugging and an Embedded Trace Macrocell (ETM) for non-intrusive instruction trace. Trace signals (TRACEPKT0–3, TRACESYNC, TRACECLK) are routed to Port 1 pins, enabling cycle-accurate program flow analysis using tools like Keil ULINKpro or Segger J-Trace - essential for validating hard real-time behavior in safety-critical firmware.
