Product details
Overview
LPC2925FBD100 from NXP Semiconductors is an ARM968E-S-based microcontroller operating up to 125 MHz, integrating 512 kB flash, 40 kB SRAM (two 16 kB blocks + 8 kB ETB), dual CAN 2.0B controllers, two LIN 2.0 masters, full-speed USB 2.0 device controller with on-chip PHY, and two 10-bit ADCs - deployed in industrial motor control, automotive body electronics, and USB-connected sensor gateways.
For engineers reviewing the LPC2925FBD100 datasheet, LPC2925FBD100 pinout, LPC2925FBD100 application, or LPC2925FBD100 equivalent, key selection criteria include its dual-CAN/LIN/USB integration, 100-pin LQFP package with 60 GPIOs, TCM-optimized real-time execution, and flexible clock/power management for low-power embedded systems.
Technical Context
The LPC2925FBD100 implements a multilayer AHB bus architecture at 125 MHz with four independent layers, enabling concurrent access to TCM, flash, SRAM, and peripherals without arbitration bottlenecks. Its dual-clock-generation units (CGU0 and CGU1) independently manage system timing: CGU0 supplies base clocks for CPU, timers, UARTs, SPI, I²C, CAN, and LIN, while CGU1 generates dedicated USB 48 MHz and configurable output clocks via its own PLL.
It features a dual-master, eight-channel GPDMA controller supporting memory-to-memory transfers and peripheral DMA (including TCM access), alongside a Vectored Interrupt Controller (VIC) with 16 priority levels and wake-up capability from power-down via CAN/LIN activity or external interrupts - critical for deterministic real-time response in automotive and industrial networks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2930FBD100 | Same ARM968E-S core, 512 kB flash, but adds Ethernet MAC and RMII interface; removes one LIN controller. | Suitable for wired industrial networking where Ethernet is required instead of dual LIN. | Select when Ethernet connectivity outweighs LIN bus support in gateway or HMI applications. |
| STM32F407VGT6 | Cortex-M4F core (168 MHz), 1 MB flash, 192 kB RAM, no native CAN FD or LIN, USB OTG HS, no EEPROM. | Better floating-point performance and DSP capability, but requires external LIN transceiver and lacks byte-erasable EEPROM. | Prefer for math-intensive control algorithms; avoid if LIN 2.0 or EEPROM persistence is mandatory. |
Compared with LPC2925FBD100, LPC2930FBD100 trades LIN for Ethernet in identical packaging and flash capacity, while STM32F407VGT6 offers higher CPU throughput but lacks integrated LIN/CAN transceivers and EEPROM - making LPC2925FBD100 uniquely suited for cost-sensitive, multi-bus automotive and industrial nodes requiring mixed-protocol integration.

FAQ
What is the maximum operating frequency of the LPC2925FBD100 CPU core?
The LPC2925FBD100 integrates an ARM968E-S processor with a maximum operating frequency of 125 MHz, achieved via its on-chip PLL with crystal oscillator input (10–25 MHz range). This frequency is sustained under full load within the specified −40 °C to +85 °C ambient temperature range and 1.8 V core supply.
Does the LPC2925FBD100 support USB device functionality without external components?
Yes, the LPC2925FBD100 includes a full-speed USB 2.0 device controller with an integrated on-chip PHY and dedicated USB_D+/D− pads (pins 12 and 13), enabling direct connection to a USB connector without external transceivers or level shifters - simplifying board design and reducing BOM cost.
How much SRAM is available on the LPC2925FBD100, and how is it allocated?
The LPC2925FBD100 provides 40 kB of total SRAM: two independent 16 kB AHB SRAM blocks (accessible for code/data), plus an 8 kB ETB SRAM that can also be used for application code or data storage - distinct from the separate 16 kB ITCM and 16 kB DTCM used exclusively for zero-wait-state instruction and data caching.
Can the LPC2925FBD100 operate with different voltage domains for core and I/O?
Yes, the LPC2925FBD100 uses dual power domains: VDD(CORE) requires 1.8 V ±5 % for the ARM968E-S core and TCMs, while VDD(IO) operates at 3.3 V for all GPIOs and peripherals. I/O pins are 5.5 V tolerant, allowing safe interfacing with legacy 5 V logic without level shifters.
What types of CAN and LIN protocols does the LPC2925FBD100 support?
The LPC2925FBD100 supports CAN 2.0B (FullCAN mode with extensive message filtering) and LIN 2.0 (with full hardware protocol handling including auto-synchronization, checksum, and schedule table management). Both controllers operate independently and support wake-up from power-down on bus activity.
