Product details

120 MHz Cortex-M3 with 512 KB Flash — what the ratings mean for the BOM

The part integrates a 6-channel 12-bit ADC and a single 10-bit DAC, an internal oscillator, and a full set of serial interfaces: CAN, I²C, SPI, SSI, SSP, UART/USART, IrDA, Microwire, and USB OTG. 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.

Industrial temperature grade and deployment context

Rated for -40 to 85 °C ambient, with a 2.4 V to 3.6 V supply range.

Frequently asked questions

What is the operating voltage of LPC1759FBD80?

The supply range is 2.4 V to 3.6 V, typically run from a 3.3 V rail in industrial designs.

Does LPC1759FBD80,551 have an internal oscillator?

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.

Can LPC1759FBD80,551 be used as a replacement for LPC1758FBD80?

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.

What is LPC1759FBD80,551's listed speed?

The core runs at 120 MHz, which is the maximum CPU clock for this Cortex-M3 device in the LPC17xx family.
