Product details
Overview
LPC2134FBD64/01 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package, featuring 128 kB flash, 16 kB SRAM, dual 10-bit 8-channel ADCs (16 total analog 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 LPC2134FBD64/01 datasheet, LPC2134FBD64/01 pinout, LPC2134FBD64/01 application, or LPC2134FBD64/01 equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral timing specs, and real-world application mappings - all derived from NXP's official Rev. 5.1 product data sheet dated 29 July 2011.
Technical Context
The LPC2134FBD64/01 implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit code execution at up to 60 MHz via a 128-bit wide memory interface and accelerator architecture. Its dual ADC subsystem includes dedicated result registers to reduce interrupt overhead, and UART0/1 integrate fractional baud rate generators and hardware handshake flow control.
It features two 32-bit timers (four capture/compare channels each), a six-output PWM unit, watchdog, and low-power RTC with independent 32 kHz clock input and VBAT supply. Peripheral clock scaling and individual enable/disable control allow fine-grained power optimization across UARTs, I²C, SPI/SSP, and ADC/DAC blocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM7TDMI-S 16/32-bit RISC processor with Thumb mode; enables 65 % code size reduction vs. ARM mode without significant performance penalty. |
| Max Clock Speed | 60 MHz via on-chip PLL (100 µs settling time); supports real-time deterministic execution for control loops and protocol stacks. |
| Flash Memory | 128 kB ISP/IAP flash; allows field firmware updates and secure bootloader operation with 100,000 erase/write cycles and 20-year data retention. |
| SRAM | 16 kB on-chip static RAM; accessible as 8/16/32-bit; used for stack, heap, buffers, and critical real-time variables with zero wait-state access. |
| ADC System | Dual 10-bit 8-channel SAR ADCs (AD0 and AD1); provides up to 16 analog inputs with 2.44 µs per-channel conversion time and dedicated result registers. |
| DAC Output | Single 10-bit voltage-output DAC (AOUT); delivers programmable analog waveform generation for sensor calibration or actuator biasing. |
| I/O & Interrupts | 47 GPIO pins (5 V tolerant), including nine edge/level-sensitive external interrupt inputs (EINT0–EINT3, RI1, DCD1, DSR1, CTS1, RTS1); supports robust event-driven system design. |
Pinout & Package
Package: LQFP64 (plastic low profile quad flat package; 64 leads; body 10 × 10 × 1.4 mm; SOT314-2). All pins are 5 V tolerant with TTL levels, hysteresis, and 10 ns slew rate control unless otherwise specified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0/TXD0/PWM1 | UART0 transmit / PWM output | Primary serial debug interface output; also serves as configurable PWM channel 1 for motor or LED control. |
| P0.27/AD0.0/CAP0.1/MAT0.1 | ADC0 channel 0 / Timer0 capture/match | Analog input always connected to pin; simultaneous use as timer capture or match disables ADC function on that pin. |
| P0.25/AD0.4/AOUT | ADC0 channel 4 / DAC output | Shared pin: AOUT active only when DAC enabled; ADC0.4 functional only when DAC disabled - mutual exclusion enforced by hardware. |
| P0.21/PWM5/AD1.6/CAP1.3 | PWM5 / ADC1 channel 6 / Timer1 capture | Multi-function pin supporting high-resolution analog sensing (AD1.6), precise timing capture (CAP1.3), or duty-cycle modulation (PWM5). |
| P1.16–P1.19/TRACEPKT0–3 | Embedded Trace macrocell outputs | Four-bit trace packet bus for real-time instruction tracing; requires external logic analyzer or debugger with ETM support. |
| VDDA / VSSA / VREF | Analog power and reference | Isolated 3.3 V analog supply (VDDA) and ground (VSSA) minimize noise coupling; VREF sets full-scale for both ADC and DAC. |
Key Features
| Feature | Design Value |
|---|---|
| Fast GPIO ports | Port pin toggling up to 3.5× faster than base LPC213x; enables precise bit-banged protocols or high-frequency digital signal generation. |
| Dedicated ADC result registers | Reduces CPU interrupt latency and ISR overhead during high-rate analog sampling - critical for closed-loop control applications. |
| Fractional baud rate UARTs | UART0/1 support exact standard baud rates (e.g., 115200, 921600) across wide clock ranges without external crystal trimming. |
| Hardware flow control | RTS/CTS, DTR/DSR, DCD/RI signals fully implemented in UART1 hardware - eliminates software polling for modem handshaking. |
| Low-power RTC with VBAT | Real-time clock maintains timekeeping during main power-down using dedicated 3.3 V backup supply (VBAT pin), independent of VDD. |

FAQ
What is the maximum operating frequency of the LPC2134FBD64/01?
The LPC2134FBD64/01 operates at a maximum CPU clock frequency of 60 MHz, achieved via its on-chip programmable PLL with 100 µs settling time. This frequency is sustained using the 128-bit wide memory interface and accelerator architecture, enabling real-time execution of control algorithms and communication stacks without wait states.
Does the LPC2134FBD64/01 support in-system programming (ISP)?
Yes, the LPC2134FBD64/01 supports In-System Programming (ISP) via its on-chip bootloader, allowing flash memory to be programmed through UART0 or UART1 without removing the device from the target board. ISP enables field firmware updates and eliminates the need for external programming hardware during development or deployment.
How many analog-to-digital converter (ADC) channels does the LPC2134FBD64/01 have?
The LPC2134FBD64/01 integrates two independent 10-bit 8-channel SAR ADCs (AD0 and AD1), providing up to 16 total analog inputs. AD0 supports inputs AD0.0–AD0.7, and AD1 supports AD1.0–AD1.7 - both with minimum conversion time of 2.44 µs per channel and dedicated result registers to reduce interrupt latency.
Can the LPC2134FBD64/01 generate PWM signals while performing ADC conversions?
Yes, the LPC2134FBD64/01 can concurrently execute PWM generation and ADC conversions. Its six-output PWM unit operates independently of the dual ADC subsystem, and shared pins (e.g., P0.21 for PWM5 and AD1.6) are functionally isolated - enabling simultaneous motor control and sensor monitoring without resource contention.
What debug interfaces are supported by the LPC2134FBD64/01?
The LPC2134FBD64/01 supports JTAG (TRST, TCK, TMS, TDI, TDO, RTCK) and EmbeddedICE RT for real-time debugging, plus Embedded Trace Macrocell (ETM) with TRACEPKT0–3 and TRACESYNC signals for instruction-level tracing. These interfaces enable non-intrusive breakpoint setting, register inspection, and live code-flow analysis during development.
