The 52 GPIOs in the 80-LQFP package give enough I/O for a keypad, a small character display, and a handful of discrete sensors without needing an external port expander.
Rated for -40 to 85 °C ambient, with a 2.4 V to 3.6 V supply range.
The supply range is 2.4 V to 3.6 V, typically run from a 3.3 V rail in industrial designs.
Yes, the device includes an internal oscillator — no external crystal is required for basic operation, though an external clock source can be used for tighter timing accuracy.
The LPC1759 is pin-compatible with the LPC1758 in the same 80-LQFP package and shares the same peripheral set, making it a direct hardware replacement. The firmware must be recompiled if it uses the additional 256 KB Flash and 32 KB SRAM of the 1759.
The core runs at 120 MHz, which is the maximum CPU clock for this Cortex-M3 device in the LPC17xx family.
