50 MHz Cortex-M0 with 64 KB Flash — what it means for the BOM
Peripherals and connectivity set
On-chip peripherals include brown-out detect, POR, PWM, and a watchdog timer — enough for standalone operation without external supervisor ICs. Serial interfaces cover I²C, SPI, Microwire, SSI, SSP, and UART/USART, so it can talk to common sensors, displays, and memory devices directly. The 8-channel 12-bit SAR ADC samples at a rate suitable for low-speed analog monitoring (temperature, pressure, current sense).
Lifecycle and sourcing
The LPC1125JBD48/303EL carries an active product status, meaning NXP continues to manufacture it and there is no announced last-time-buy or end-of-life window. For volume BOM commitments, this part is sourced and quoted to order through independent distribution — availability and current pricing confirmed at quote time. No second-source alternate is listed in the official cross-reference, but the LPC1100 family shares the same Cortex-M0 core and 48-LQFP footprint across density options, so a pin-compatible migration within the family is possible if memory or I/O requirements shift.
