The LPC2104/2105/2106 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.
The P89LPC952 is a single-chip microcontroller, available in low cost packages, based ona high performance processor architecture that executes instructions in two to four clocks,six times the rate of standard 80C51 devices. Many system-level functions have beenincorporated into the P89LPC952 in order to reduce component count, board space, andsystem cost.2.
