This manual introduces the development process of the LPC900 series microcontrollers, including program writing, configuration information details, encryption words, burning, etc.
This manual provides a complete development workflow for the LPC900 series microcontroller, including an introduction to the device, programming procedures, example circuits, and project creation using Keil uVision2. It also details how to generate Hex files, configure system options, and program the chip.
Additional sections explain the configuration bits, boot status and vector settings, encryption options, and troubleshooting tips for ISP/ICP operations, with reference material and version history at the end. This manual is written in Chinese.
| CPU Core | 80C51 compatible core |
|---|---|
| Interfaces | UART, SPI, I2C, comparator, ADC/DAC modules |
| Instruction Speed | 6× that of a standard 8051 |
| Internal RC Oscillator | 7.3728 MHz |
| Power‑down Current | <1 µA |

The manual uses Keil uVision2 as the compiler and debugger for LPC900 projects.
Select the project’s Options for Target, enable the Create File option on the Output page, then press F7 to compile and produce the Hex file.
The WDTE bit enables (1) or disables (0) the watchdog timer; when enabled it can reset the chip on timeout.
