The 64-LQFP package (10x10 mm body) is hand-solderable with a fine-tip iron and a steady hand — a weekend maker can breadboard it on a breakout board, and a production line can reflow it without special handling.","metaTitle":"NXP LPC2131FBD64,151 ARM7 MCU, 60MHz, 32KB Flash, 8KB RAM","metaDescription":"NXP LPC2131FBD64,151 ARM7 microcontroller, 60MHz, 32KB Flash, 8KB RAM, 47 I/O, 3.3V, -40 to 85°C, 64-LQFP.

The LPC2138FBD64 (512 KB Flash) is another drop-in option for designs needing more memory."},{"question":"Can I replace LPC2131FBD64 with LPC2132FBD64?","answer":"Yes, the LPC2132FBD64 is a pin-compatible replacement. It shares the same 64-LQFP footprint, ARM7 core, 60 MHz clock, and peripheral set, but doubles the Flash to 64 KB and the RAM to 16 KB. No PCB layout changes are needed."},{"question":"Where can I buy LPC2131FBD64,151?","answer":"This obsolete part is sourced through independent distribution channels.
