ZLG LPC2103 Microcontroller User Manual
This manual introduces the LPC2103 microcontroller, covering its 16/32‑bit ARM7TDMI‑S core, memory resources, peripheral set, and pin configurations for both LQFP48 and PLCC44 packages. It provides detailed hardware schematics, pin‑out tables, and descriptions of GPIO, timers, ADC, UART, SPI, SSP, and interrupt controller.
The document also explains the development environment, including CodeWarrior IDE, EasyJTAG‑H debugging, and example projects. Step‑by‑step instructions guide users through creating, compiling, and debugging applications, as well as configuring PLL, power modes, and real‑time clock. This manual is written in Chinese.
