Product data sheet
1. General description
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 pared to existing 8/16-bit architectures.
The LPC1102/1104 operate at CPU frequencies of up to 50 MHz.
The peripheral plement 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 munication.
- Better positioning of the XTALIN pin for easier PCB layout.
