Product details
Overview
LPC1317FBD48,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for low-power embedded control with USB device capability, 64 kB flash, 8 kB SRAM, and 40 GPIO pins in LQFP48 package. It operates up to 72 MHz, integrates a 12-bit ADC (8 channels, 500 kSamples/s), two SSP interfaces, I²C-bus (Fast-mode Plus, 1 Mbit/s), and a USART supporting RS-485, smart card (ISO 7816-3), and synchronous modes - used in industrial USB peripherals and handheld medical scanners.
For engineers reviewing the LPC1317FBD48,551 datasheet, LPC1317FBD48,551 pinout, LPC1317FBD48,551 application, or LPC1317FBD48,551 equivalent, key selection criteria include its USB 2.0 Full-Speed device controller (no dedicated USB PLL), absence of on-chip EEPROM, 40 GPIO count in LQFP48, and support for Deep power-down wake-up via PIO0_16 - critical for battery-powered portable instrumentation and RS-485 node controllers.
Technical Context
The LPC1317FBD48,551 implements the ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated NVIC for deterministic interrupt handling. Its clock system combines a 1–25 MHz crystal oscillator, 12 MHz ±1% IRC, and dual PLLs - one for CPU (PLL0) and one dedicated to USB (USB PLL), though the LPC1317 variant excludes the USB PLL per datasheet Table 2.
Peripheral integration includes four general-purpose timers (two 32-bit, two 16-bit), a Windowed WatchDog Timer with internal low-power WDO, and analog subsystem comprising an 8-channel 12-bit ADC with 500 kSamples/s sampling rate. The device supports multiple low-power modes (Sleep, Deep-sleep, Power-down, Deep power-down) managed by an integrated PMU and wake-up via GPIO, watchdog, or USB activity - but USB wake-up is disabled in LPC1317 due to lack of USB PLL and USB transceiver hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 3-stage pipeline, Harvard architecture - enables deterministic real-time execution with low interrupt latency. |
| Max Clock Frequency | 72 MHz - achieved via PLL0 using crystal or IRC input; no USB PLL present in LPC1317, limiting USB functionality to device-only mode without dedicated clock synthesis. |
| Memory | 64 kB flash (256-byte page erase), 8 kB SRAM, no EEPROM - supports ISP/IAP via UART/USB bootloader but lacks persistent nonvolatile data storage. |
| Analog Interface | 12-bit ADC, 8 input channels, 500 kSamples/s - sufficient for sensor acquisition in portable medical devices and industrial monitoring nodes. |
| Serial Interfaces | 1× USART (RS-485/9-bit/smart card), 2× SSP (SPI-compatible), 1× I²C-bus (Fast-mode Plus, 1 Mbit/s) - enables multi-protocol fieldbus connectivity without external level shifters. |
| GPIO & Interrupts | 40 programmable GPIO pins (LQFP48), 8 configurable as edge/level-sensitive interrupts, 2 grouped GPIO interrupt modules - supports complex peripheral event handling in compact designs. |
| Power Management | Four reduced-power modes; Deep power-down wake-up via PIO0_16 only - enables ultra-low standby current (<1 µA) in battery-operated handheld scanners. |
Pinout & Package
Package: LQFP48 (SOT313-2), plastic low profile quad flat package, 48 leads, body 7 × 7 × 1.4 mm, operating temperature −40 °C to +85 °C, single 3.3 V supply (2.0 V to 3.6 V).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET/PIO0_0 | Reset input / General-purpose I/O | Active-Low reset with 20 ns glitch filter; also debug select (LOW = JTAG, HIGH = SWD); default state is input with pull-up. |
| SWDIO/PIO0_15/AD4/CT32B1_MAT2 | Debug I/O / ADC input / Timer match output | Primary debug interface pin (Serial Wire Debug); shares function with ADC channel 4 and 32-bit timer 1 match output 2 - requires careful signal routing in debug-enabled production firmware. |
| PIO0_16/AD5/CT32B1_MAT3/WAKEUP | ADC input / Timer match output / Wake-up trigger | Dedicated Deep power-down wake-up pin with 20 ns glitch filter; must be pulled HIGH to enter and LOW to exit DPD mode - critical for battery life optimization in portable instruments. |
| PIO0_4/SCL & PIO0_5/SDA | I²C-bus clock/data | Open-drain I²C pins supporting Fast-mode Plus (1 Mbit/s); high-current sink enabled only when Fast-mode Plus is configured in IOCON - ensures robust bus driving without external pull-ups in noisy environments. |
| PIO0_18/RXD & PIO0_19/TXD | USART receive/transmit | Full-duplex UART interface supporting RS-485 half-duplex mode and asynchronous smart card (ISO 7816-3); RXD doubles as UART ISP entry pin - enables field firmware updates without debugger. |
Key Features
| Feature | Design Value |
|---|---|
| ARM Cortex-M3 NVIC | Hardware-accelerated nested interrupt handling with configurable priority - reduces ISR latency to <12 cycles for time-critical motor control loops. |
| Programmable Glitch Filter | Eight GPIO pins support software-configurable digital noise suppression - eliminates false triggers from EMI in industrial RS-485 gateways. |
| High-Current GPIO Drivers | P0_7 provides 20 mA source; P0_4/P0_5 provide 20 mA sink in Fast-mode Plus mode - directly drives LEDs or I²C bus capacitance without external buffers. |
| Repetitive Interrupt Timer (RI Timer) | Dedicated low-overhead timer for periodic OS tick or sensor polling - frees main CPU timers for application-specific timing tasks. |
| Boot ROM API Support | 16 kB ROM includes USB API, power control, flash IAP/ISP, and EEPROM emulation functions - accelerates development of secure firmware update mechanisms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1347FBD48 | Includes USB PLL and full USB 2.0 transceiver; adds 2 kB EEPROM; same 64 kB flash/8 kB SRAM/40 GPIO. | Supports USB host/device dual-role and precise USB clock synchronization; required for USB audio class compliance. | Select LPC1347FBD48 when USB device timing accuracy or EEPROM-based parameter storage is mandatory. |
| LPC1316FBD48 | 48 kB flash, no USB controller, identical package and peripheral set otherwise. | Suitable for cost-sensitive RS-485 or I²C-only nodes where USB is unnecessary. | Choose LPC1316FBD48 to reduce BOM cost while retaining ADC, timers, and low-power features for non-USB industrial sensing. |
Compared with LPC1317FBD48,551, the LPC1347FBD48 adds USB clock precision and nonvolatile storage at higher unit cost, while the LPC1316FBD48 removes USB entirely to lower price - making LPC1317FBD48,551 the optimal balance for USB-capable portable instrumentation needing no EEPROM.

FAQ
Does LPC1317FBD48,551 support USB host functionality?
No. The LPC1317FBD48,551 implements only a USB 2.0 Full-Speed device controller with no USB OTG or host capability. It lacks the USB PLL and transceiver hardware required for host operation. Applications requiring USB host must use LPC17xx or LPC18xx families. The LPC1317FBD48,551 is strictly a USB device endpoint.
What is the maximum ADC sampling rate achievable on LPC1317FBD48,551?
The LPC1317FBD48,551 supports a maximum ADC sampling rate of 500 kSamples/s across its 8 input channels. This rate is achievable in burst mode with optimized clock configuration and minimal conversion overhead. The actual sustained throughput depends on software handling of conversion complete interrupts and data buffering - the LPC1317FBD48,551's 8 kB SRAM provides adequate space for real-time acquisition buffers.
Can LPC1317FBD48,551 enter Deep power-down mode and wake up via USB activity?
No. Unlike LPC134x variants, the LPC1317FBD48,551 does not include the USB PLL or full USB transceiver, so USB activity cannot trigger wake-up from Deep power-down mode. Valid wake-up sources are PIO0_16 (WAKEUP pin), reset, watchdog interrupt, or selected GPIO pins - as confirmed in Section 2.7 "Power control" of the datasheet. USB-related wake-up is unavailable on LPC1317FBD48,551.
Is there on-chip EEPROM in LPC1317FBD48,551?
No. The LPC1317FBD48,551 has no on-chip EEPROM memory. Table 2 in the datasheet explicitly lists EEPROM as "-" for all LPC131x variants. Persistent data storage must be implemented externally or emulated in flash using NXP's IAP routines - a design constraint clearly distinguishing LPC1317FBD48,551 from LPC134x parts which include 2 kB EEPROM.
What debug interfaces are supported by LPC1317FBD48,551?
The LPC1317FBD48,551 supports Serial Wire Debug (SWD) and standard JTAG interfaces. SWD uses SWCLK (PIO0_10) and SWDIO (PIO0_15) pins; JTAG uses TDI, TDO, TMS, TRST, and TCK (mapped to PIO0_11, PIO0_13, PIO0_12, PIO0_14, and PIO0_10 respectively). Both are fully functional for programming and real-time debugging - the LPC1317FBD48,551 does not require external debug probes beyond standard ARM-compliant adapters.
