LPC11C14FBD48

NXP恩智浦/LPC11C14FBD48 托盘

Overview

The is an ARM Cortex-M0 microcontroller designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The peripheral complement of the LPC11C14FBD48 includes 32 kB of flash memory, 8 kB of data memory, one C_CAN controller, one Fast-mode Plus I²C-bus interface, one RS-485/EIA-485 UART, two SPI interfaces with SSP features, four general purpose counter/timers, a 10-bit ADC, and 40 general purpose I/O pins. On-chip C_CAN drivers and flash In-System Programming tools via C_CAN are included.
