The LPC2119/2129/2194/2292/2294 are based on a 16/32-bit ARM7TDMI-S CPU microcontroller that supports real-time simulation and tracing and includes 128/256k bytes (kB) of embedded high-speed Flash memory. A 128-bit-wide memory interface and a unique acceleration structure enable 32-bit code to run at maximum clock speed. Applications with strict code size control can reduce code size by more than 30% using the 16-bit Thumb mode with little performance loss. Due to the LPC2119/2129/2194/2292/2294's smaller 64- and 144-pin packages, extremely low power consumption, multiple 32-bit timers, 4-channel 10-bit ADCs, 2/4-channel CAN (64-pin and 144-pin packages) and up to 9 external interrupts, they are particularly suitable for industrial control, medical systems, access control and POS machines. In a 64-pin package, up to 46 GPIOs can be used. In a 144-pin package, GPIOs up to 76 (using external memory) ~ 112 (single-chip applications) can be used. Due to the built-in wide range of serial communication interfaces, they are also very suitable for communication gateways, protocol converters, embedded soft modems and various other types of applications.
The LPC2119/2129/2194/2292/2294 series are 16/32‑bit ARM7TDMI‑S microcontrollers with low power consumption, multiple timers, ADCs, CAN interfaces and extensive GPIO, making them suitable for industrial control, medical devices, access control, POS terminals and communication gateways.
The manual describes the device architecture, memory sizes, peripheral functions, register maps, programming options (ISP/IAP), and real‑time debugging features such as EmbeddedICE‑RT and ETM, giving developers the information needed to design and debug applications. This manual is written in Chinese.
