NXP Semiconductors LPC2930FBD208,551

Overview

LPC2930FBD208,551 from NXP Semiconductors is an ARM968E-S-based microcontroller operating up to 125 MHz, integrating dual 32 kB TCM, 56 kB SRAM, 768 kB flash, USB 2.0 OTG, dual CAN, dual LIN, three 10-bit ADCs (5 V and 3.3 V ranges), and 104 GPIOs in a 208-pin LQFP package - designed for industrial control, automotive body electronics, and communication gateways.

For engineers reviewing the LPC2930FBD208,551 datasheet, LPC2930FBD208,551 pinout, LPC2930FBD208,551 application, or LPC2930FBD208,551 equivalent, this page delivers verified core parameters, validated pin functions, confirmed peripheral integration (USB OTG + dual CAN + dual LIN), exact memory mapping, and real-world application context - all aligned with NXP's Rev. 5 product data sheet dated 27 September 2010.

Technical Context

The LPC2930FBD208,551 implements a multi-layer AHB bus architecture running at 125 MHz with four independent layers, enabling concurrent high-bandwidth access to TCM, SRAM, flash, and peripherals. Its dual Clock Generation Units (CGU0/CGU1) provide independent clock scaling: CGU0 drives CPU and system clocks via PLL (10–25 MHz input → 125 MHz max), while CGU1 generates dedicated USB clocks and configurable outputs.

Peripherals are distributed across three APB clusters and subsystem-specific buses, with DMA support spanning GPDMA controller (eight channels, dual-master), USB, UARTs, SPIs, and TCM memories. The device uses a modular reset strategy managed by the Reset Generator Unit (RGU), and power management is handled by a configurable Power Management Unit (PMU) enabling per-module clock gating and dynamic voltage scaling.

FAQ

What is the maximum operating frequency of the LPC2930FBD208,551?

The LPC2930FBD208,551 features an ARM968E-S processor with a maximum CPU clock frequency of 125 MHz, achieved via its on-chip PLL accepting 10–25 MHz crystal inputs. This frequency is sustained across the full −40 °C to +85 °C ambient operating range when supplied with 1.8 V ±5 % core voltage and proper thermal management.

Does the LPC2930FBD208,551 support 5 V analog inputs directly?

Yes, the LPC2930FBD208,551 includes a dedicated 5 V-tolerant ADC subsystem (ADC0) with eight single-ended inputs and a 5 V reference supply (VDDA(ADC5V0)). This allows direct connection of 5 V sensors - such as potentiometers, thermistors, or battery monitors - without external level-shifting circuitry, preserving signal integrity and reducing BOM cost.

How many CAN interfaces does the LPC2930FBD208,551 integrate?

The LPC2930FBD208,551 integrates two independent CAN 2.0B controllers (CAN0 and CAN1), each with full hardware message filtering, transmit/receive FIFOs, and support for both standard and extended identifiers. These controllers operate concurrently and are mapped to separate GPIO pin groups (e.g., P0[0]/P0[1] for CAN0, P3[4]/P3[5] for CAN1), enabling dual-bus automotive diagnostics and actuator control.

Is the LPC2930FBD208,551 pin-compatible with earlier LPC29xx variants like LPC2929FBD144?

No, the LPC2930FBD208,551 is not pin-compatible with LPC2929FBD144. While both belong to the LPC29xx family and share identical peripheral functionality, the LPC2930FBD208,551 uses a 208-pin LQFP package (SOT486-2) with expanded signal routing - including full 32-bit external memory bus and additional GPIOs - whereas LPC2929FBD144 uses a 144-pin LQFP (SOT486-1) with reduced pinout and no external bus interface.

What debug interfaces are supported by the LPC2930FBD208,551?

The LPC2930FBD208,551 supports IEEE 1149.1 JTAG for boundary-scan testing and real-time in-circuit emulation, plus Embedded Trace Buffer (ETB) with 8 kB dedicated SRAM for instruction and data trace. JTAGSEL pin selects between ARM debug mode (LOW) and boundary scan (HIGH), and the device includes full ETM/ETB debug functionality compliant with ARM CoreSight specifications.
