The internal oscillator and 24-channel 10-bit ADC reduce external component count. Operating from 1.71 V to 3.6 V over the -40°C to 85°C industrial temperature range, it is specified for factory-floor and outdoor telecom enclosures where temperature swings are routine. ## 125 MHz ARM9 — what the core speed means for the bus The ARM9 core runs at 125 MHz. The 768 KB Flash holds firmware plus a bootloader and parameter block. ## Last Buy — final ordering window The LPC2929FBD144,551 is classified as Last Buy by NXP. This means the manufacturer has announced end-of-life and is accepting final orders within a defined window. Once that window closes, the part will no longer be produced. For BOM lines that depend on this MCU, the immediate action is to secure last-time-buy quantities or identify a replacement. NXP has not published a direct pin-compatible successor for this specific order code in the LPC2900 series; any replacement will likely require a PCB spin or firmware port.","metaTitle":"NXP LPC2929FBD144,551 ARM9 MCU, 125 MHz, 768 KB Flash, Last Buy","metaDescription":"NXP LPC2929FBD144,551 ARM9 MCU with 125 MHz core, 768 KB Flash, 56 KB SRAM, 16 KB EEPROM, CAN/USB/LIN, 104 I/O, -40°C to 85°C.
