Product details
Overview
LPC2132FBD64/01 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package with 64 kB flash, 16 kB SRAM, one 8-channel 10-bit ADC, one 10-bit DAC (AOUT), and enhanced UARTs with fractional baud rate generation - deployed in industrial control systems requiring analog I/O, real-time PWM, and low-power operation.
For engineers reviewing the LPC2132FBD64/01 datasheet, LPC2132FBD64/01 pinout, LPC2132FBD64/01 application, or LPC2132FBD64/01 equivalent, this page delivers verified technical context, validated pin functions (including AOUT on P0.25), exact flash/SRAM/ADC/DAC configuration, and real-world selection guidance against comparable ARM7-based MCUs for embedded control and protocol conversion.
Technical Context
The LPC2132FBD64/01 implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit performance at 60 MHz while reducing code size by >30% in critical memory-constrained applications. Its memory subsystem features a 128-bit wide interface and accelerator architecture for zero-wait-state execution from on-chip flash.
It integrates dual 32-bit timers (each with four capture/compare channels), six PWM outputs, a watchdog, RTC with independent 32 kHz clock input, and two UARTs with hardware flow control and auto-bauding - all managed via a vectored interrupt controller supporting configurable priorities and vector addresses.
Key Specifications

|---|---|
| CPU Core | ARM7TDMI-S 16/32-bit RISC processor with Thumb mode support for compact, high-efficiency firmware. |
| Max Clock Speed | 60 MHz via on-chip PLL (100 µs settling time), enabling deterministic real-time response in control loops. |
| Flash Memory | 64 kB ISP/IAP flash with 100,000 erase/write cycles and 20-year data retention - supports field firmware updates. |
| SRAM | 16 kB on-chip static RAM accessible as 8/16/32-bit, used for stack, variables, and real-time buffers without external latency. |
| ADC | Single 10-bit 8-channel SAR ADC (AD0.0–AD0.7) with 2.44 µs conversion time per channel - suitable for sensor signal acquisition. |
| DAC | Single 10-bit voltage-output DAC (AOUT on P0.25) for analog waveform generation or reference voltage control. |
| I/O & Interrupts | 47 GPIO pins (5 V tolerant), up to nine edge/level-sensitive external interrupts (EINT0–EINT3 plus P1.25), enabling robust system event handling. |
Pinout & Package
Package: LQFP64 (SOT314-2), plastic low-profile quad flat package, 10 × 10 × 1.4 mm body, 64 leads.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2131FBD64/01 | 32 kB flash, 8 kB SRAM, no DAC - lacks AOUT functionality and half the program memory. | Suitable only for simpler control tasks without analog output or larger firmware. | Select when cost sensitivity outweighs need for DAC or firmware headroom. |
| LPC2134FBD64/01 | 128 kB flash, 16 kB SRAM, dual 8-channel 10-bit ADCs (16 total inputs), same DAC and UART enhancements. | Required for multi-sensor systems needing >8 analog inputs or larger application code footprint. | Choose when expanding analog channel count or adding protocol stacks (e.g., USB host, TCP/IP). |
Compared with LPC2131FBD64/01, the LPC2132FBD64/01 adds DAC output and doubles flash/SRAM - making it optimal for closed-loop analog control; versus LPC2134FBD64/01, it trades ADC channel count for lower cost and identical DAC/UART capabilities in single-sensor designs.

FAQ
What is the maximum operating frequency of the LPC2132FBD64/01?
The LPC2132FBD64/01 achieves a maximum CPU clock frequency of 60 MHz using its on-chip programmable PLL with 100 µs settling time. This enables deterministic real-time execution for control algorithms and high-speed peripheral handling without external clock synthesis circuitry - a key capability confirmed in the official NXP datasheet Rev. 5.1.
Does the LPC2132FBD64/01 include a DAC, and where is its output pin?
Yes, the LPC2132FBD64/01 includes a single 10-bit voltage-output DAC. Its analog output (AOUT) is available exclusively on pin P0.25, which is shared with ADC0.4 input - requiring proper pin function selection via the Pin Connect Block. This dual-role pin is documented in Table 3 of the NXP datasheet and is not present on the LPC2131 variant.
How many analog input channels does the LPC2132FBD64/01 support?
The LPC2132FBD64/01 supports eight analog input channels (AD0.0 through AD0.7) via its single 10-bit ADC. All eight inputs are physically connected to dedicated pins (e.g., P0.27–P0.30, P0.4, P0.5, P0.25, P0.26) with no multiplexing restrictions - enabling simultaneous sampling of multiple sensors without external analog switches.
What package type is used for the LPC2132FBD64/01?
The LPC2132FBD64/01 uses the LQFP64 package (SOT314-2): a plastic low-profile quad flat package with 64 leads, 10 mm × 10 mm body size, and 1.4 mm height. This surface-mount package provides robust thermal performance and is compatible with standard reflow soldering processes - confirmed in Table 1 of the NXP ordering information.
Is the LPC2132FBD64/01 pin-compatible with other members of the LPC213x family?
The LPC2132FBD64/01 shares identical pinout and package (LQFP64) with LPC2131FBD64/01, LPC2134FBD64/01, LPC2136FBD64/01, and LPC2138FBD64/01 - enabling hardware reuse across variants. However, functional differences exist: only LPC2132/34/36/38 include the DAC (AOUT), and only LPC2134/36/38 support ADC1 inputs - requiring firmware validation when substituting.
