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.
