描述 Description

The LPC2917/2919/01 combine an ARM968E-S CPU core with two integrated TCM blocks operating at frequencies of up to 125 MHz, CAN and LIN, 56 kB SRAM, up to 768 kB flash memory, external memory interface, two 10-bit ADCs, and multiple serial and parallel interfaces in a single chip targeted at consumer, industrial, medical, and communication markets. To optimize system power consumption, the LPC2917/2919/01 has a very flexible Clock Generation Unit (CGU) that provides dynamic clock gating and scaling.

特性 Features

Main Features
? ARM968E-S processor running at frequencies of up to 125 MHz maximum.
? Multi-layer AHB system bus at 125 MHz with three separate layers.
? Dual-master, eight-channel GPDMA controller on the AHB multi-layer matrix which can be used with the SPI interfaces and the UARTs, as well as for memory-to-memory transfers including the TCM memories.
? External Static Memory Controller (SMC) with eight memory banks; up to 32-bit data bus; up to 24-bit address bus.
? Up to 108 general-purpose I/O pins with programmable pull-up, pull-down, or bus keeper.
? Vectored Interrupt Controller (VIC) with 16 priority levels.
? Up to 19 level-sensitive external interrupt pins, including CAN and LIN wake-up features.
? Configurable clock-out pin for driving external system clocks.
? Processor wake-up from power-down via external interrupt pins; CAN or LIN activity.
? Flexible Reset Generator Unit (RGU) able to control resets of individual modules.
? Second CGU (CGU1) with its own PLL generates a configurable clock output.
? Standard Arm test and debug interface with real-time in-circuit emulator.
? Boundary-scan test supported.
? ETM/ETB debug functions with 8 kB of dedicated SRAM also accessible for application code and data storage.

? 144-pin LQFP package.
? -40 °C to +85 °C ambient operating temperature range.
