Product details
Overview
LPC1316FBD48,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller in LQFP48 package, operating at up to 72 MHz with 48 kB flash, 8 kB SRAM, no USB interface, and 40 GPIO pins. It integrates a 12-bit ADC (8 channels, 500 kSamples/s), two SSP controllers, one Fast-mode Plus I²C-bus (1 Mbit/s), and an RS-485/UART with smart card support - deployed in industrial control and handheld scanners.
For engineers reviewing the LPC1316FBD48,551 datasheet, LPC1316FBD48,551 pinout, LPC1316FBD48,551 application, or LPC1316FBD48,551 equivalent, key selection criteria include its non-USB variant status within the LPC131x family, absence of on-chip EEPROM, fixed 40-pin GPIO count in LQFP48, and compatibility with SWD/JTAG debug interfaces.
Technical Context
The LPC1316FBD48,551 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 - though only the main PLL is active (USB PLL omitted), enabling CPU operation up to 72 MHz without USB clock domain requirements.
Peripheral routing uses AHB-to-APB bridges with dedicated bus slaves for flash, SRAM, ROM, and peripherals. The device supports four low-power modes (Sleep, Deep-sleep, Power-down, Deep power-down), wake-up via GPIO, watchdog, or reset, and includes a programmable Windowed Watchdog Timer with internal low-power WDO oscillator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 72 MHz max - enables real-time deterministic execution with hardware divide and Thumb-2 instruction set. |
| Memory | 48 kB flash (256-byte page erase), 8 kB SRAM - sufficient for firmware + data buffers in compact embedded applications. |
| Analog | 12-bit ADC, 8 channels, 500 kSamples/s - supports high-resolution sensor acquisition with minimal external signal conditioning. |
| Serial Interfaces | 2 × SSP, 1 × I²C-FM+ (1 Mbit/s), 1 × USART with RS-485/9-bit/smart card - enables multi-protocol fieldbus and peripheral connectivity. |
| GPIO & Timers | 40 configurable GPIO pins; 4 timers (2×16-bit, 2×32-bit) with 13 match outputs and 8 capture inputs - suitable for PWM generation and pulse measurement. |
| Power & Temp | Single 3.3 V supply (2.0–3.6 V), −40 °C to +85 °C - qualified for industrial environments without external voltage translation or thermal derating. |
Pinout & Package
LQFP48 package: plastic low-profile quad flat package, 48 leads, body 7 × 7 × 1.4 mm, standard JEDEC MO-220 footprint compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET/PIO0_0 | Reset input / GPIO | Active-low reset with 20 ns glitch filter; also selects SWD vs JTAG debug mode during boot. |
| SWDIO/PIO0_15 | Debug I/O / GPIO | Primary serial wire debug interface; doubles as ADC input 4 and timer match output. |
| PIO0_18/RXD/CT32B0_MAT0 | USART RX / Timer output | Receiver input for UART/RS-485; also serves as 32-bit timer 0 match output 0 for PWM or event timing. |
| PIO0_19/TXD/CT32B0_MAT1 | USART TX / Timer output | Transmitter output for full-duplex serial comms; also provides second match output for synchronized waveform generation. |
| PIO0_4/SCL & PIO0_5/SDA | I²C clock/data | Open-drain I²C-FM+ interface supporting 1 Mbit/s - requires external pull-ups; high-current sink enabled for Fast-mode Plus compliance. |
| PIO0_22/AD6/CT16B1_MAT1/MISO1 | ADC input / Timer / SPI | Shared function pin: analog input for channel 6, 16-bit timer 1 match output, or SPI1 slave-in - requires careful multiplexing in firmware. |
Key Features
| Feature | Design Value |
|---|---|
| ARM Cortex-M3 NVIC | Hardware-based nested interrupt controller with configurable priority levels - eliminates software polling overhead in time-critical ISR handling. |
| Programmable Glitch Filter | Eight GPIO pins support configurable digital noise suppression - enables reliable edge-triggered interrupts in electrically noisy industrial settings. |
| High-Current GPIO Drivers | P0_7 delivers 20 mA source; P0_4/P0_5 deliver 20 mA sink - directly drives LEDs or small relays without external drivers. |
| Repetitive Interrupt Timer (RI Timer) | Dedicated low-overhead timer for periodic OS tick or sensor sampling - operates independently of main timers to reduce scheduling jitter. |
| Boot ROM API Support | 16 kB ROM includes ISP/IAP, power control, and clock management APIs - reduces firmware size and accelerates development of field-upgradable systems. |

FAQ
Does LPC1316FBD48,551 support USB device functionality?
No, LPC1316FBD48,551 does not include a USB 2.0 device controller. It belongs to the non-USB variant of the LPC131x family (LPC1315/16/17), unlike LPC1345/46/47 which integrate USB. This omission reduces silicon area and power consumption, making LPC1316FBD48,551 ideal for applications relying solely on UART, I²C, or SSP interfaces.
What is the maximum ADC sampling rate supported by LPC1316FBD48,551?
LPC1316FBD48,551 supports a maximum ADC sampling rate of 500 kSamples/s across its 8-channel 12-bit successive approximation register (SAR) ADC. This performance enables real-time acquisition of fast-changing analog signals such as motor current or audio envelope detection without external oversampling hardware.
How many general-purpose I/O pins does LPC1316FBD48,551 provide in the LQFP48 package?
LPC1316FBD48,551 provides exactly 40 general-purpose I/O pins in the LQFP48 package. This count is confirmed in Table 2 of the datasheet and distinguishes it from the LQFP64 variant (51 GPIO) and HVQFN33 variant (28 GPIO), ensuring consistent pin-count expectations for PCB layout and firmware resource allocation.
Is on-chip EEPROM available in LPC1316FBD48,551?
No, LPC1316FBD48,551 does not include on-chip EEPROM. Table 2 explicitly lists EEPROM as "−" for all LPC131x variants (LPC1315/16/17), whereas LPC134x variants (LPC1345/46/47) include 2 kB. Persistent data storage must be implemented using flash sectors with wear-leveling or external EEPROM/FRAM.
Which debug interfaces are supported by LPC1316FBD48,551?
LPC1316FBD48,551 supports both Serial Wire Debug (SWD) and JTAG interfaces. SWD is the recommended primary debug method due to its 2-pin footprint (SWCLK and SWDIO), while JTAG remains available for boundary scan testing. Both interfaces are accessible through the same physical pins (PIO0_10/SWCLK and PIO0_15/SWDIO) with mode selection controlled at reset.
