LPC2927/2929
ARM9 microcontroller with CAN, LIN, and USB
Rev. 02 — 22 June 2009
Preliminary data sheet
1. General description
The LPC2927/2929 combine an ARM968E-S CPU core with two integrated TCM blocks
operating at frequencies of up to 125 MHz, Full-speed USB 2.0 OTG and device
controller, CAN and LIN, 56 kB SRAM, up to 768 kB flash memory, 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 LPC2927/2929 has a very flexible Clock Generation Unit
(CGU) that provides dynamic clock gating and scaling.
2. Features
I ARM968E-S processor running at frequencies of up to 125 MHz maximum.
I Multi-layer AHB system bus at 125 MHz with four separate layers.
I On-chip memory:
N Two Tightly Coupled Memories (TCM), 32 kB Instruction TCM (ITCM), 32 kB Data
TCM (DTCM).
N Two separate internal Static RAM (SRAM) instances; 32 kB SRAM and 16 kB
SRAM.
N 8 kB ETB SRAM also available for code execution and data.
N Up to 768 kB high-speed flash-program memory.
N 16 kB true EEPROM, byte-erasable and programmable.
I 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.
I External Static Memory Controller (SMC) with eight memory banks; up to 32-bit data
bus; up to 24-bit address bus.
I Serial interfaces:
N USB 2.0 full-speed device/OTG controller with dedicated DMA controller and
on-chip device PHY.
N Two-channel CAN controller supporting FullCAN and extensive message filtering.
N 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.
N Two 550 UARTs with 16-byte Tx and Rx FIFO depths, DMA support, and
RS485/EIA-485 (9-bit) support.
N Three full-duplex Q-SPIs with four slave-select lines; 16 bits wide; 8 locations deep;
Tx FIFO and Rx FIFO.
N Two I2C-bus interfaces.

5.2 Pin description
5.2.1 General description
The LPC2927/2929 uses five ports: port 0 with 32 pins, ports 1 and 2 with 28 pins each,
port 3 with 16 pins, and port 5 with 2 pins. Port 4 is not used. The pin to which each
function is assigned is controlled by the SFSP registers in the SCU. The functions
combined on each port pin are shown in the pin description tables in this section.

6. Functional description
6.1 Architectural overview
The LPC2927/2929 consists of:
• An ARM968E-S processor with real-time emulation support
• An AMBA multi-layer Advanced High-performance Bus (AHB) for interfacing to the
on-chip memory controllers
• Two DTL buses (an universal NXP interface) for interfacing to the interrupt controller
and the Power, Clock and Reset Control cluster (also called subsystem).
• Three ARM Peripheral Buses (APB - a compatible superset of ARM's AMBA
advanced peripheral bus) for connection to on-chip peripherals clustered in
subsystems.
• One ARM Peripheral Bus for event router and system control.
