LPC2930  
ARM9 flashless microcontroller with CAN, LIN, and USB  
Rev. 03 — 16 April 2010  
Product data sheet  
1. General description  
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, 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.  
2. Features and benefits  
„ 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.  
„ Dual-master, eight-channel GPDMA controller on the AHB multilayer 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.  
„ Serial interfaces:  
‹ USB 2.0 full-speed Host/OTG/Device controller with dedicated DMA controller and  
on-chip device PHY.  
‹ Two-channel CAN controller supporting FullCAN and extensive message filtering  
‹ Two LIN master controllers with full hardware support for LIN communication. The  
LIN interface can be configured as UART to provide two additional UART  
interfaces.  
‹ Two 550 UARTs with 16-byte Tx and Rx FIFO depths, DMA support, modem  
control, and RS-485/EIA-485 (9-bit) support.  
‹ Three full-duplex Q-SPIs with four slave-select lines; 16 bits wide; 8 locations deep;  
Tx FIFO and Rx FIFO.  
‹ Two I2C-bus interfaces.
