Product details

Memory budget: 8 KB Flash, 4 KB SRAM

8 KB of Flash limits firmware to small-footprint applications. 4 KB of SRAM is enough for a few hundred bytes of stack, a modest data buffer, and global variables for a dozen I/O points.

Peripherals and I/O for a compact control board

28 GPIOs in a 32-pin package means most pins are shared with the serial interfaces (I2C, SPI, UART/USART) and the 8-channel 10-bit ADC. Plan the pin allocation early: the ADC inputs occupy port 0 pins, and the serial interfaces share alternate functions on the same port.

Frequently asked questions

What is the LPC1111FHN33/202,5 used for?

This 32-bit ARM Cortex-M0 MCU at 50 MHz with 8 KB Flash and 4 KB SRAM is used in cost-sensitive embedded control applications such as industrial sensor nodes, motor control I/O boards, simple HMI backends, and battery-powered instrumentation.

What is the closest pin-compatible alternative to LPC1111FHN33/202,5?

Within the LPC1100L series, higher-density parts such as the LPC1114 or LPC1115 (with 32 KB or 64 KB Flash) share the same 32-HVQFN footprint and pinout, offering a firmware-scaling path without a board respin.
