The UART are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and
embedded trace support, together with 128 kB of embedded high speed flash memory. A
128-bit wide memory interface and a unique accelerator architecture enable 32-bit code
execution at maximum clock rate. For critical code size applications, the alternative 16-bit
Thumb mode reduces code by more than 30 % with minimal performance penalty.
Due to their tiny size and low power consumption, these microcontrollers are ideal for
applications where miniaturization is a key requirement, such as access control and
point-of-sale. With a wide range of serial communications interfaces and on-chip SRAM
options up to 64 kB, they are very well suited for communication gateways and protocol
converters, soft modems, voice recognition and low end imaging, providing both large
buffer size and high processing power. Various 32-bit timers, PWM channels, and 32
GPIO lines make these microcontrollers particularly suitable for industrial control and
medical systems.
Remark: Throughout the data sheet, the term LPC2104/2105/2106 will apply to devices
with and without /00 and /01 suffixes. Suffixes will be used to differentiate devices
whenever they include new features.
