The LPC2109/2119/2129 are based on a 16/32-bit ARM7TDMI-S CPU with real-time
emulation and embedded trace support, together with 64/128/256 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.
With their compact 64-pin package, low power consumption, various 32-bit timers,
4-channel 10-bit ADC, two advanced CAN channels, PWM channels and 46 fast GPIO
lines with up to nine external interrupt pins these microcontrollers are particularly suitable
for automotive and industrial control applications, as well as medical systems and
fault-tolerant maintenance buses. With a wide range of additional serial communications
interfaces, they are also suited for communication gateways and protocol converters as
well as many other general-purpose applications.
Remark: Throughout the data sheet, the term LPC2109/2119/2129 will apply to devices
with and without the /00 or /01 suffixes. The /00 or the /01 suffix will be used to
differentiate from other devices only when necessary.
