180 MHz Cortex-M3 with 768 KB Flash — what it means for the BOM
The LPC1825JBD144E: 32-bit ARM Cortex-M3 MCU clocked at 180 MHz, with 768 KB Flash and 136K x 8 SRAM on-chip. Rated for -40 to 105 °C. Supply range is 2.2 V to 3.6 V.
Connectivity and peripheral set
The LPC1825JBD144E includes CANbus, USB OTG, Ethernet MAC via EBI/EMI, and a full set of serial interfaces (I²C, SPI, SSI, SSP, UART/USART, IrDA, Microwire). That means it can serve as a system hub — bridging a CAN-based motor drive to a USB-connected HMI, or aggregating sensor data over SPI and forwarding it over Ethernet. The EBI/EMI interface also allows glueless connection to external SRAM, NOR Flash, or an FPGA, which is handy when the on-chip 136K x 8 RAM isn't enough for large frame buffers or data logging. Includes motor control PWM, I²S, 8-channel 10-bit ADC, and single 10-bit DAC.
Lifecycle and sourcing
The LPC1825JBD144E is listed as Active, meaning NXP continues to manufacture it and no last-time-buy notice has been issued. For a BOM freeze, that removes the immediate obsolescence risk. The part is available through independent distribution; we source and quote it to order against an RFQ, with current pricing and availability confirmed at quote time. No second-source alternate is listed in the official cross-reference, so plan for single-sourced supply — but the active status and broad distributor coverage keep the channel open.
