LPC2377FBD144,551

The LPC2377FBD144,551 is a 16-/32-bit Microcontroller based on ARM7TDMI-S core with RISC architecture operates at a maximum frequency of 72MHz. A 128-bit wide memory interface and an unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical performance in interrupt service routines and DSP algorithms, this increases performance up to 30 % over Thumb mode. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty. The device incorporates 512kB internal flash, 58kB internal RAM, 8-channel 10-bit A/D converter, 10-bit D/A converter, an Ethernet, four 32-bit timers and real-time clock (RTC) and 104 general-purpose I/O pins. This device also features peripherals like four UARTs, three inter-integrated circuit (I2C), one serial peripheral interface (SPI) modules and one integrated interchip sound (I2S).
