Product details
Overview
LPC2104FBD48/01 from NXP Semiconductors is a 32-bit ARM7TDMI-S microcontroller with 128 kB flash, 16 kB SRAM, 60 MHz max CPU clock, 32 GPIO pins (5 V tolerant), and dual UARTs with fractional baud rate generators - deployed in access control systems, point-of-sale terminals, and industrial protocol converters.
For engineers reviewing the LPC2104FBD48/01 datasheet, LPC2104FBD48/01 pinout, LPC2104FBD48/01 application, or LPC2104FBD48/01 equivalent, key selection criteria include its −40 °C to +85 °C industrial temperature grade, LQFP48 package with trace/debug support, Fast GPIO capability, and SSP interface availability exclusive to /01 variants.
Technical Context
The LPC2104FBD48/01 implements the ARM7TDMI-S core with Thumb instruction set for code density optimization, paired with a 128-bit-wide memory interface enabling full 60 MHz execution speed. Its on-chip memory subsystem includes 128 kB ISP/IAP flash (100k erase/write cycles) and 16 kB SRAM accessible in 8/16/32-bit modes.
Peripherals include two 32-bit timers (7 capture/compare channels), a 6-channel PWM unit, Real-Time Clock, Watchdog, Vectored Interrupt Controller (16 vectored IRQ slots), and dual UARTs with hardware flow control (RTS/CTS/DSR/DTR/DCD/RI). The /01 suffix confirms inclusion of SSP serial controller and enhanced autobauding features not present in /00 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM7TDMI-S 32-bit RISC processor with Thumb mode for 30 % smaller code size at minimal performance cost. |
| Max Clock Speed | 60 MHz via on-chip PLL (100 µs settling time); supports 1–25 MHz external crystal input. |
| Flash Memory | 128 kB ISP/IAP flash with 1 ms/512 B programming and 400 ms sector/full-erase - enables field firmware updates without external programmer. |
| SRAM | 16 kB on-chip static RAM, accessible in 8/16/32-bit widths for flexible data buffering and stack allocation. |
| I/O Voltage | Dual supply: 1.65–1.95 V core (1.8 V ±8.3 %), 3.0–3.6 V I/O (3.3 V ±10 %) with 5 V tolerant pins - simplifies mixed-voltage system interfacing. |
| Operating Temp | −40 °C to +85 °C industrial grade - validated for deployment in harsh environments including factory automation and outdoor kiosks. |
| Serial Interfaces | Two UARTs (16C550-compatible, fractional baud, hardware flow control), Fast I²C (400 kbit/s), SPI/SSP (SPI, 4-wire SSI, Microwire), all mapped to GPIO via Pin Connect Block. |
Pinout & Package
LPC2104FBD48/01 uses an LQFP48 package (7 mm × 7 mm × 1.4 mm, SOT313-2) with 48 leads, including 32 GPIO pins (P0.0–P0.31), dual power domains (VDD(1V8), VDD(3V3)), JTAG/trace debug pins, and dedicated peripheral function multiplexing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0/TXD0/PWM1 | UART 0 transmit / PWM output | Primary serial debug or host communication channel; PWM1 usable for motor control or LED dimming. |
| P0.1/RXD0/PWM3 | UART 0 receive / PWM output | Full-duplex UART 0 interface; PWM3 provides independent timing signal for auxiliary peripherals. |
| P0.2/SCL/CAP0.0 | I²C clock / Timer 0 capture | Open-drain I²C-bus clock line compliant with 400 kHz spec; CAP0.0 enables edge-triggered event counting. |
| P0.3/SDA/MAT0.0 | I²C data / Timer 0 match | Open-drain I²C-bus data line; MAT0.0 generates precise periodic interrupts or waveform edges. |
| P0.19/MAT1.2/TCK | Timer 1 match / JTAG clock | Shared pin for real-time waveform generation or boundary-scan test clock - requires careful multiplexing during debug vs runtime. |
| RESET | Active-low reset input | 5 V tolerant TTL-level reset with hysteresis; initiates cold boot and resets all peripherals to default states. |
| VDD(1V8) | Core power supply | 1.8 V ±8.3 % regulated supply for CPU and internal logic - must be decoupled per layout guidelines to ensure stability at 60 MHz. |
| VDD(3V3) | I/O power supply | 3.3 V ±10 % supply for GPIO and peripheral I/O - enables direct interfacing with 3.3 V logic and 5 V tolerant operation. |
Key Features
| Feature | Design Value |
|---|---|
| Fast GPIO port | Port pin toggle up to 3.5× faster than legacy LPC2104; allows real-time bit-banging and deterministic I/O response. |
| Fractional baud rate UARTs | UART 0/1 support precise non-integer baud rates (e.g., 115200, 921600) across wide clock ranges - eliminates external clock dividers. |
| SSP serial controller | Hardware-buffered SPI/SSI/Microwire interface available only on /01 variants - offloads CPU during high-speed sensor or display data transfers. |
| Diversified Code Read Protection | Multiple CRP levels prevent unauthorized flash readout while permitting selective debugging or bootloader updates. |
| Embedded Trace Macrocell | Non-intrusive real-time instruction trace via TRACEPKT[0:3], TRACESYNC, and TRACECLK pins - enables cycle-accurate profiling without halting execution. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2106FBD48/01 | Same core, package, and /01 feature set but with 64 kB SRAM instead of 16 kB - no flash increase. | Preferred where larger buffer space is needed for complex protocol stacks or audio processing. | Select LPC2106FBD48/01 when application requires >16 kB RAM; pinout and firmware are identical. |
| LPC2138FBD64 | 64-pin LQFP variant with USB 2.0 device controller, 512 kB flash, and 32 kB SRAM - different package and peripheral set. | Suitable for USB-connected embedded hosts but requires PCB redesign and driver adaptation. | Choose LPC2138FBD64 only if USB interface is mandatory; not a drop-in replacement due to pin count and layout change. |
Compared with LPC2104FBD48/01, LPC2106FBD48/01 offers immediate RAM scalability without firmware or layout changes, while LPC2138FBD64 introduces USB capability at the cost of board redesign and increased BOM complexity.

FAQ
What distinguishes the LPC2104FBD48/01 from the LPC2104FBD48/00?
The LPC2104FBD48/01 includes the SSP serial controller and enhanced autobauding capabilities in both UARTs - features absent in the /00 variant. These are confirmed in Section 2.1 of the datasheet and enable robust SPI-based sensor interfacing and adaptive serial communication without software overhead. The LPC2104FBD48/01 retains identical flash, RAM, and package specifications.
Does the LPC2104FBD48/01 support in-system programming (ISP)?
Yes, the LPC2104FBD48/01 supports In-System Programming via its UART0 interface using the on-chip bootloader. Flash programming takes 1 ms per 512 B line, and sector or full-chip erase completes in 400 ms. This capability allows field firmware updates without removing the LPC2104FBD48/01 from the target board.
What is the purpose of the DBGSEL pin on the LPC2104FBD48/01?
The DBGSEL pin on the LPC2104FBD48/01 selects between primary and secondary JTAG pin groups at reset: when pulled HIGH, it enables debug mode and routes JTAG signals to P0.27–P0.31; when LOW, it defaults to normal operation with JTAG on P0.17–P0.21. This dual-pin-group architecture supports trace functionality without sacrificing GPIO count during active operation.
Can the LPC2104FBD48/01 operate with a 3.3 V-only power supply?
No - the LPC2104FBD48/01 requires two separate supplies: VDD(1V8) at 1.65–1.95 V for the core and VDD(3V3) at 3.0–3.6 V for I/O. Using only 3.3 V on VDD(1V8) violates absolute maximum ratings and will damage the LPC2104FBD48/01. A dedicated 1.8 V regulator is mandatory for core power.
How many interrupt priority levels does the Vectored Interrupt Controller (VIC) support in the LPC2104FBD48/01?
The VIC in the LPC2104FBD48/01 supports three interrupt classes: Fast Interrupt Request (FIQ), 16 configurable vectored IRQs (with individually assignable priorities), and non-vectored IRQs sharing a default handler. Priority assignment is fully programmable via VICIntSelect and VICVectPriority registers, enabling deterministic real-time response for time-critical peripherals like UARTs and timers.
