LPC2378

LPC2377/78 Single-chip 16-bit/32-bit microcontrollers; 512 kB flash with ISP/IAP, Ethernet, USB 2.0, CAN, and 10-bit ADC/DAC Rev. 6.1 — 16 October 2013 Product data sheet 1. General description The LPC2377/78 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation that combines the microcontroller with 512 kB of embedded 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 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 LPC2377/78 are ideal for multi-purpose serial communication applications. It incorporates a 10/100 Ethernet Media Access Controller (MAC), USB full speed device with 4 kB of endpoint RAM (LPC2378 only), four UARTs, two CAN channels (LPC2378 only), an SPI interface, two Synchronous Serial Ports (SSP), three I2C-bus interfaces, an I2S-bus interface, and an External Memory Controller (EMC). This blend of serial communications interfaces combined with an on-chip 4 MHz internal oscillator, SRAM of 32 kB, 16 kB SRAM for Ethernet, 8 kB SRAM for USB and general purpose use, together with 2 kB battery powered SRAM make this device suited for communication gateways and protocol converters. Various 32-bit timers, an improve...
