General description
The LPC2141/42/44/46/48 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S
CPU with real-time emulation and embedded trace support, that combine microcontroller
with embedded high-speed flash memory ranging from 32 kB to 512 kB. A 128-bit wide
memory interface and a unique accelerator architecture enable 32-bit code execution at
the 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, LPC2141/42/44/46/48 are ideal for
applications where miniaturization is a key requirement, such as access control and
point-of-sale. Serial communications interfaces ranging from a USB 2.0 Full-speed device,
multiple UARTs, SPI, SSP to I
2
C-bus and on-chip SRAM of 8 kB up to 40 kB, make these
devices 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, single or dual 10-bit ADC(s), 10-bit DAC, PWM
channels and 45 fast GPIO lines with up to nine edge or level sensitive external interrupt
pins make these microcontrollers suitable for industrial control and medical systems.
