For engineers reviewing the LPC2132FBD64/01 datasheet, LPC2132FBD64/01 pinout, LPC2132FBD64/01 application, or LPC2132FBD64/01 equivalent, this page delivers verified functional roles per pin, confirmed ADC/DAC timing specs, validated UART0/1 hardware flow control, Fast GPIO toggle performance (3.5× baseline), and BOD-controlled power-down wake-up capability.
Technical Context
The LPC2132FBD64/01 implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit code execution at 60 MHz via 128-bit wide memory interface and accelerator architecture. It integrates dual APB peripherals (UART0/1, I²C0/1, SPI/SSP) and AHB-connected timers, ADC, DAC, and vectored interrupt controller with configurable priorities.
Its memory subsystem includes 64 kB on-chip flash (100k erase/write cycles, 20-year retention) and 16 kB static RAM accessible as 8/16/32-bit. The device supports ISP/IAP via on-chip bootloader, with single-sector erase in 400 ms and 256 B programming in 1 ms.

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, which settles in 100 µs. This frequency is sustained via a 128-bit wide memory interface and accelerator architecture, enabling full-speed 32-bit instruction execution without wait states.
Does the LPC2132FBD64/01 include a DAC, and how is it accessed?
Yes, the LPC2132FBD64/01 includes a single 10-bit voltage-output DAC. Its output appears on pin P0.25 as AOUT. When configured as DAC output, the digital I/O function of P0.25 is disabled - the pin operates exclusively in analog mode with dedicated output buffer and reference (VREF) input.
How many analog inputs does the LPC2132FBD64/01 support, and what is their resolution?
The LPC2132FBD64/01 supports eight analog inputs (AD0.0 through AD0.7) via a single 10-bit successive-approximation ADC. Conversion time is as low as 2.44 µs per channel, and dedicated result registers minimize interrupt latency during high-frequency sampling.
What debug interfaces are supported by the LPC2132FBD64/01?
The LPC2132FBD64/01 supports JTAG (TRST, TCK, TMS, TDI, TDO, RTCK) for boundary scan and ICE debugging, plus Embedded Trace Macrocell (ETM) with TRACEPKT[0:3], TRACESYNC, and TRACECLK pins for real-time instruction trace - enabling non-intrusive analysis without halting program flow.
Is the LPC2132FBD64/01 pin-compatible with other members of the LPC213x family?
Yes, the LPC2132FBD64/01 in LQFP64 package shares identical pinout with LPC2131FBD64/01, LPC2134FBD64/01, LPC2136FBD64/01, and LPC2138FBD64/01. Peripheral register mapping and GPIO functionality are consistent; differences lie only in flash/SRAM size, ADC count, and DAC presence - all software-compatible within the same toolchain.
