Product details
Overview
LPC2136FBD64/01 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package, featuring 256 kB flash, 32 kB SRAM, dual 10-bit 8-channel ADCs (16 total inputs), single 10-bit DAC, and 47 GPIO pins with nine external interrupt lines - deployed in industrial control systems requiring real-time analog acquisition and PWM-driven actuation.
For engineers reviewing the LPC2136FBD64/01 datasheet, LPC2136FBD64/01 pinout, LPC2136FBD64/01 application, or LPC2136FBD64/01 equivalent, key selection criteria include its 60 MHz CPU clock, Fast GPIO capability (3.5× toggling speed vs legacy LPC213x), hardware flow-controlled UART0/1 with fractional baud rate generation, and dual ADC support for synchronized multi-channel sampling in embedded measurement nodes.
Technical Context
The LPC2136FBD64/01 implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit performance at reduced code size (up to 30% smaller than ARM mode). Its memory subsystem uses a 128-bit wide interface and accelerator architecture to sustain full 60 MHz operation from on-chip flash.
Peripherals are organized across AHB and APB buses: dual 10-bit ADCs (AD0 and AD1) operate independently with dedicated result registers to minimize interrupt latency; the 10-bit DAC (AOUT) provides variable analog output; and two 32-bit timers (Timer0/Timer1) each support four capture/compare channels plus PWM generation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2138FBD64/01 | 512 kB flash, same 32 kB SRAM, dual ADC, DAC, and peripherals - no architectural or pinout change | Supports larger firmware images, complex protocol stacks, or integrated web server functionality | Select when firmware size exceeds 256 kB or future-proofing for feature expansion is required |
| LPC2148FBD64 | Same ARM7TDMI-S core but adds USB 2.0 Device controller, 512 kB flash, and enhanced interrupt controller - not pin-compatible | Enables direct USB connectivity (e.g., CDC ACM virtual COM port), eliminating external USB-UART bridge | Choose only if USB host/device capability is mandatory and PCB redesign is acceptable |

FAQ
What is the maximum operating frequency of the LPC2136FBD64/01?
The LPC2136FBD64/01 achieves a maximum CPU clock frequency of 60 MHz using its on-chip programmable PLL, which settles in 100 µs. This frequency is sustained by the 128-bit wide memory interface and accelerator architecture, enabling full-speed 32-bit instruction execution directly from flash memory without wait states.
Does the LPC2136FBD64/01 support in-system programming (ISP)?
Yes, the LPC2136FBD64/01 supports In-System Programming via its built-in bootloader, allowing flash memory to be programmed through UART0 or UART1 without requiring a dedicated programmer. ISP enables field firmware updates, and In-Application Programming (IAP) permits runtime erasure and reprogramming of flash sectors - for example, storing calibration data or configuration parameters.
How many analog-to-digital converter (ADC) channels does the LPC2136FBD64/01 have?
The LPC2136FBD64/01 integrates two independent 10-bit successive approximation register (SAR) ADCs: ADC0 with eight channels (AD0.0–AD0.7) and ADC1 with eight channels (AD1.0–AD1.7), providing up to 16 total analog inputs. Conversion time is as low as 2.44 µs per channel, and dedicated result registers reduce interrupt servicing overhead.
What is the function of pin P0.25 on the LPC2136FBD64/01?
Pin P0.25 on the LPC2136FBD64/01 serves a dual role: as ADC0 input channel 4 (AD0.4) or as the 10-bit DAC output (AOUT). When configured as AOUT, the digital I/O section of the pin is disabled, and it delivers a buffered analog voltage referenced to VREF. This pin is not available on LPC2131 and is shared exclusively between ADC0 and DAC functions.
Is the LPC2136FBD64/01 pin-compatible with other members of the LPC213x family?
Yes, the LPC2136FBD64/01 is fully pin-compatible with all LQFP64 variants in the LPC213x/01 family - including LPC2131FBD64/01, LPC2132FBD64/01, LPC2134FBD64/01, and LPC2138FBD64/01 - sharing identical pinout, package dimensions (SOT314-2), and electrical characteristics, enabling drop-in replacement based on flash/SRAM requirements.
