The NXP LPC1758FBD80Y is a 32-bit ARM Cortex-M3 MCU running at 100 MHz, with 512 KB of Flash and 64 KB of RAM. The 80-LQFP (12×12 mm) package keeps the board footprint compact, and the -40 to 85 °C temperature range covers most factory-floor and outdoor telecom enclosures.
At 100 MHz, the Cortex-M3 core delivers single-cycle multiply and hardware divide, keeping interrupt latency predictable for real-time loops.
Both are 100 MHz Cortex-M3 MCUs in the same 80-LQFP package with 512 KB Flash and 64 KB RAM. The LPC1768 adds a second CAN controller and a few extra peripherals; the LPC1758 is the value-optimized variant. They are pin-compatible, so a board designed for one can accept the other with a firmware change.
Yes, the LPC1758FBD80Y is a direct Flash-density upgrade from the LPC1756 (512 KB vs 256 KB) in the same 80-LQFP package and pinout. Firmware written for the LPC1756 will run on the LPC1758, and the extra Flash is available for expanded code or data.
The supply range is 2.4 V to 3.6 V, covering both 3.3 V and 2.5 V logic rails.
