The LPC2101/2102/2103 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-SCPU with real-TIme emulaTIon that combines the microcontroller with 8 kB, 16 kB or 32 kBof embedded high-speed flash memory. A 128-bit wide memory interface and a uniqueaccelerator architecture enable 32-bit code execuTIon at the maximum clock rate. ForcriTIcal performance in interrupt service routines and DSP algorithms, this increasesperformance up to 30 % over Thumb mode. For critical code size applications, thealternative 16-bit Thumb mode reduces code by more than 30 % with minimalperformance penalty.Due to their tiny size and low power consumption, the LPC2101/2102/2103 are ideal forapplications where miniaturization is a key requirement. A blend of serial communicationsinterfaces ranging from multiple UARTs, SPI to SSP and two I2C-buses, combined withon-chip SRAM of 2 kB/4 kB/8 kB, make these devices very well suited for communicationgateways and protocol converters. The superior performance also makes these devicessuitable for use as math coprocessors. Various 32-bit and 16-bit timers, an improved10-bit ADC, PWM features through output match on all timers, and 32 fast GPIO lines withup to nine edge or level sensitive external interrupt pins make these microcontrollersparticularly suitable for industrial control and medical systems.
