The LPC2148 microcontroller is based on a 16-bit/32-bit ARM7TDMI-S
CPU with real-time emulation and embedded 512kB high-speed flash memory. 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 pct with minimal performance penalty.
Due to their tiny size and low power consumption, LPC2148 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 I2C-bus and on-chip SRAM of 32 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, many 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.
