Eight 12-bit ADC channels handle sensor acquisition for industrial control loops, motor feedback, or panel instrumentation. The peripheral set includes I²C, SPI/SSP, and UART interfaces, plus a brown-out detect, POR, and watchdog timer for unsupervised operation in factory-floor or outdoor telecom enclosures.
The HVQFN package (7×7 mm) with exposed pad requires a thermal via pattern under the pad for heat spreading.
The supply range is 2 V to 3.6 V, covering single-cell lithium and 3.3 V regulated rails.
The ARM Cortex-M3 core runs at 72 MHz.
Within the LPC13xx series, pin-compatible variants differ by Flash/RAM density and ADC channel count. The LPC1317 is the 64 KB Flash option; the LPC1313 (32 KB Flash) and LPC1347 (64 KB Flash, USB) are same-package alternatives worth evaluating for a second-source qualification.
