NXP LPC2930 USB2.0和多种接口方案
NXP 公司的LPC2930集成了工作频率高达125MHz ARM968E-S CPU核和两个TCM区块,全速USB 2.0主/OTG/设备控制器,CAN和LIN,以及56kB SRAM,外接存储器接口,三个10位ADC,多个串行和平行接口,适合用于消费类电子,工业,医疗和通信市场.本文介绍LPC2930主要特性,方框图以及多种USB接口框图.
The LPC2930 combine an ARM968E-S CPU core with two integrated TCM blocks operating at frequencies of up to 125 MHz, Full-speed USB 2.0 Host/OTG/Device controller, CAN and LIN, 56 kB SRAM, external memory interface, three 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 LPC2930 has a very flexible Clock Generation Unit (CGU) that provides dynamic clock gating and scaling.
LPC2930主要特性:
ARM968E-S processor running at frequencies of up to 125 MHz maximum.
Multilayer AHB system bus at 125 MHz with four separate layers.
On-chip memory:
Two Tightly Coupled Memories (TCM), 32 kB Instruction TCM (ITCM), 32 kB Data TCM (DTCM).
Two separate internal Static RAM (SRAM) instances; 32 kB SRAM and 16 kB SRAM.
8 kB ETB SRAM, also usable for code execution and data.
