Overview

The LPC1102/1104 are an ARM Cortex-M0 based, low-cost 32-bit MCU, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures.

The LPC1102/1104 operate at CPU frequencies of up to 50 MHz.

The peripheral complement of the LPC1102/1104 includes 32 kB of flash memory, 8 kB of data memory, one RS-485/EIA-485 UART, one SPI interface with SSP features, four general purpose counter/timers, a 10-bit ADC, and 11 general purpose I/O pins.

**Remark:** The LPC1104 has a revised pinout and contains several features not found in the LPC1102:

* Two extra GPIO pins PIO0_1 and PIO0_6.

* Extra match output CT32B0_MAT2.

* CLKOUT feature.

* Easier re-entry to ISP via PIO0_1.

* SSP0_CLK available on two pins A1 and A2 to support debugging of SSP communication.

* Better positioning of the XTALIN pin for easier PCB layout.
