The NXP LPC1817JBD144551 is an ARM Cortex-M3 32-bit single-core MCU from the LPC18xx series, clocked at 180 MHz. It carries 1 MB of Flash program memory, 136 KB of SRAM, and 16 KB of on-chip EEPROM — enough to hold firmware, data buffers, and calibration parameters without an external serial EEPROM on the board.
No last-time-buy window is open, and no end-of-life notice is documented.
The LPC1817JBD144551 is available to order through independent distribution. Submit an RFQ for current pricing and availability — no minimum order quantity beyond standard tray multiples.
The ARM Cortex-M3 core runs at 180 MHz, placing it in the mid-to-high performance tier for industrial MCUs.
NXP provides RoHS and REACH compliance documentation for this part. The 144-LQFP package is lead-free and halogen-free per NXP's standard material declarations.
