Product details
Overview
LPC1313FBD48/01 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller in LQFP48 package, operating up to 72 MHz with 32 kB flash, 8 kB SRAM, dual SSP controllers (SSP0 + SSP1), Windowed Watchdog Timer (WWDT), and I²C Fast-mode Plus (1 Mbit/s). It targets low-power embedded control in lighting systems and alarm panels requiring robust peripheral integration and deep-sleep wake-up via 40 GPIO pins.
For engineers reviewing the LPC1313FBD48/01 datasheet, LPC1313FBD48/01 pinout, LPC1313FBD48/01 application, or LPC1313FBD48/01 equivalent, key selection criteria include its LPC1300L-series power profiles, second SSP interface (exclusive to /01 variants), WWDT support, 10-bit 8-channel ADC, and 48-pin LQFP package with 5 V-tolerant GPIOs and configurable pull-ups.
Technical Context
The LPC1313FBD48/01 implements an ARM Cortex-M3 core with Harvard architecture, 3-stage pipeline, and internal prefetch unit enabling speculative branching. Its memory subsystem includes 32 kB on-chip flash with ISP/IAP capability and 8 kB SRAM, both accessible via AHB-Lite bus.
Peripherally, it integrates UART with RS-485 support, I²C-bus (Fast-mode Plus, 1 Mbit/s), two SSP controllers (SSP0 standard, SSP1 exclusive to /01 variant), four general-purpose timers (including CT32B0/1 and CT16B0/1), 10-bit 8-channel ADC, and Serial Wire Debug/Trace interface. Power management includes Sleep, Deep-sleep, and Deep power-down modes with wake-up via dedicated logic on up to 40 functional pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3, 72 MHz max - enables real-time deterministic execution with NVIC for low-latency interrupt handling. |
| Memory | 32 kB flash + 8 kB SRAM - sufficient for standalone firmware with USB stack, communication protocols, and sensor processing. |
| I/O Interface | 48-pin LQFP, 42 GPIOs with 5 V tolerance, configurable pull-up/down, hysteresis, and edge/level interrupts - simplifies interfacing with industrial-level sensors and legacy buses. |
| Serial Peripherals | 1× UART (RS-485 capable), 1× I²C Fast-mode Plus (1 Mbit/s), 2× SSP (SSP0 + SSP1) - supports multi-protocol fieldbus connectivity including SPI-based sensors and displays. |
| Analog & Timing | 10-bit 8-channel ADC, WWDT, programmable clock output (system/IRC/CPU/watchdog source) - enables precise analog monitoring and fail-safe system supervision without external components. |
| Power Management | Three reduced-power modes (Sleep/Deep-sleep/Deep power-down), BOD with four forced-reset thresholds - meets energy budgets for battery-backed alarm and metering applications. |
Pinout & Package
Package: LQFP48 (SOT313-2), 7 × 7 × 1.4 mm body, 48 leads, lead pitch 0.5 mm. RoHS-compliant, thermal-enhanced plastic package suitable for reflow soldering and industrial temperature range operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET/PIO0_0 (Pin 3) | Reset input / General-purpose I/O | Active-low reset with 20 ns glitch filter; also serves as digital I/O with 10 ns glitch filter and internal pull-up - enables hardware reset and flexible signal routing. |
| PIO0_1/CLKOUT/CT32B0_MAT2 (Pin 4) | Clock output / Timer match / GPIO | Provides configurable system clock derivative (IRC/CPU/oscillator/watchdog) for test instrumentation or synchronous peripherals - eliminates need for external clock generator. |
| PIO2_0/DTR/SSEL1 (Pin 2) | UART DTR / SSP1 slave select | Dual-function pin: asserts Data Terminal Ready for modem control or selects slave device on SSP1 - leverages /01-specific second SSP for daisy-chained sensor networks. |
| PIO2_1/DSR/SCK1 (Pin 13) | UART DSR / SSP1 serial clock | Supports full-duplex UART handshaking or clocks SSP1 transfers - enables simultaneous serial comms and peripheral expansion without multiplexing conflict. |
| PIO2_2/DCD/MISO1 (Pin 26) | UART DCD / SSP1 MISO | Enables carrier detection in modem links or receives data from SSP1 slaves - critical for fault-aware communication in alarm and metering gateways. |
| PIO2_3/RI/MOSI1 (Pin 38) | UART RI / SSP1 MOSI | Signals ring indication or transmits data to SSP1 slaves - completes full-duplex SSP1 interface for external DACs, EEPROMs, or display drivers. |
| VDD (Pins 8, 44) | Power supply | 3.3 V nominal supply for core, peripherals, and ADC reference - single-rail design reduces BOM count and PCB complexity. |
| VSS (Pins 5, 41) | Ground | Dual ground connections minimize noise coupling between analog and digital sections - improves ADC accuracy and timer stability. |
Key Features
| Feature | Design Value |
|---|---|
| Second SSP controller (SSP1) | Exclusive to LPC1313FBD48/01 - enables independent SPI bus for sensor arrays or display interfaces while SSP0 handles communication ICs. |
| Windowed Watchdog Timer (WWDT) | Prevents runaway code by requiring periodic windowed refresh - essential for safety-critical alarm and white-goods control where silent failure is unacceptable. |
| Power profiles in boot ROM | One function call optimizes active/sleep current draw - eliminates manual register configuration and accelerates low-power firmware development. |
| Programmable pseudo open-drain mode | GPIOs emulate true open-drain behavior for I²C or 1-wire buses without external pull-ups - reduces component count and board area. |
| High-current sink on I²C pins | 20 mA sink capability on SCL/SDA when Fast-mode Plus enabled - ensures reliable bus signaling at 1 Mbit/s over longer traces or higher capacitance loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1343FBD48 | Includes USB 2.0 full-speed device controller and on-chip PHY; lacks WWDT and second SSP; same 32 kB flash/8 kB SRAM. | Targets USB-connected devices (e.g., HID peripherals); unsuitable where WWDT or dual SPI is mandatory. | Select only if USB device functionality is required and WWDT/dual SSP are not needed. |
| LPC1313FHN33/01 | Same LPC1300L features (WWDT, dual SSP, power profiles) but in 33-pin HVQFN package; 33 GPIOs vs. 42; no DTR/DSR/DCD/RI pins. | Better suited for space-constrained designs lacking UART modem handshaking requirements. | Choose for compact footprint when full 48-pin LQFP I/O count and modem signals are unnecessary. |
Compared with LPC1343FBD48, the LPC1313FBD48/01 trades USB for enhanced reliability (WWDT) and peripheral flexibility (SSP1), while versus LPC1313FHN33/01 it delivers greater I/O density and modem interface support at the cost of larger PCB area.

FAQ
What distinguishes LPC1313FBD48/01 from non-/01 variants like LPC1313FBD48?
The LPC1313FBD48/01 includes critical LPC1300L-series enhancements absent in base variants: Windowed Watchdog Timer (WWDT), four-level brownout detect for forced reset, second SSP controller (SSP1), programmable pseudo open-drain GPIO mode, and internal pull-ups tied to full VDD. These features directly impact system reliability and peripheral expansion capability in the LPC1313FBD48/01.
Does LPC1313FBD48/01 support USB functionality?
No, the LPC1313FBD48/01 does not include USB hardware. USB Device controller and on-chip PHY are exclusive to LPC1342/43 variants. The LPC1313FBD48/01 focuses on robust serial communication via UART, I²C Fast-mode Plus, and dual SSP - making it ideal for non-USB industrial control nodes where USB is unnecessary.
How many ADC channels does LPC1313FBD48/01 provide, and what is their resolution?
The LPC1313FBD48/01 integrates a 10-bit successive-approximation ADC with 8 input channels (AD0–AD7), mapped to PIO0_11, PIO1_0–PIO1_2, SWDIO/PIO1_3, PIO1_4–PIO1_5, and PIO1_10–PIO1_11. This resolution supports accurate voltage/current sensing in lighting ballasts, temperature monitoring in white goods, and analog sensor interfacing in alarm systems using the LPC1313FBD48/01.
What debug interfaces are supported by LPC1313FBD48/01?
The LPC1313FBD48/01 supports Serial Wire Debug (SWD) and Serial Wire Trace (SWO) via dedicated SWCLK (Pin 29) and SWDIO (Pin 39) pins. It does not support JTAG. This two-pin debug interface reduces PCB routing complexity while enabling full-featured debugging, real-time trace, and flash programming - essential for rapid firmware iteration on the LPC1313FBD48/01.
Is LPC1313FBD48/01 pin-compatible with other LPC13xx LQFP48 variants?
Yes, the LPC1313FBD48/01 shares identical LQFP48 pinout and package dimensions (SOT313-2) with LPC1313FBD48, LPC1342FBD48, and LPC1343FBD48. However, functionality differs: SSP1, WWDT, and power profile registers are only active in /01 variants, and USB pins are no-connection (NC) on LPC1313FBD48/01 - ensuring safe drop-in replacement where those features are unused.
