1. Introduction

1.1 About this document

This document lists detailed information about the LPC2917/19 device. It focuses on

factual information like pinning, characteristics etc. Short descriptions are used to outline

the concept of the features and functions. More details and background on developing

applications for this device are given in the LPC2917/19 User Manual (see Ref. 1). No

explicit references are made to the User Manual.

1.2 Intended audience

This document is written for engineers evaluating and/or developing systems, hard-

and/or software for the LPC2917/19. Some basic knowledge of ARM processors and

architecture and ARM968E-S in particular is assumed (see Ref. 2).

2. General description

2.1 Architectural overview

The LPC2917/19 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 (a universal NXP interface) for interfacing to the interrupt controller

and the Power, Clock and Reset Control cluster (also called subsystem)

•Three VLSI Peripheral Buses (VPB - a compatible superset of ARM's AMBA

advanced peripheral bus) for connection to on-chip peripherals clustered in

subsystems.

The LPC2917/19 configures the ARM968E-S processor in little-endian byte order. All

peripherals run at their own clock frequency to optimize the total system power

consumption. The AHB2VPB bridge used in the subsystems contains a write-ahead buffer

one transaction deep. This implies that when the ARM968E-S issues a buffered write

action to a register located on the VPB side of the bridge, it continues even though the

actual write may not yet have taken place. Completion of a second write to the same

subsystem will not be executed until the first write is finished.

2.2 ARM968E-S processor

The ARM968E-S is a general purpose 32-bit RISC processor, which offers high

performance and very low power consumption. The ARM architecture is based on

Reduced Instruction Set Computer (RISC) principles, and the instruction set and related

decode mechanism are much simpler than those of micro-programmed Complex

Instruction Set Computers (CISC). This simplicity results in a high instruction throughput

and impressive real-time interrupt response from a small and cost-effective controller

core.

Amongst the most compelling features of the ARM968E-S are:

•Separate directly connected instruction and data Tightly Coupled Memory (TCM)

interfaces

•Write buffers for the AHB and TCM buses

•Enhanced 16 x 32 multiplier capable of single-cycle MAC operations and 16-bit fixed-

point DSP instructions to accelerate signal-processing algorithms and applications.

Pipeline techniques are employed so that all parts of the processing and memory systems

can operate continuously. The ARM968E-S is based on the ARMv5TE five-stage pipeline

architecture. Typically, in a three-stage pipeline architecture, while one instruction is being

executed its successor is being decoded and a third instruction is being fetched from

memory. In the five-stage pipeline additional stages are added for memory access and

write-back cycles.

The ARM968E-S processor also employs a unique architectural strategy known as

THUMB, which makes it ideally suited to high-volume applications with memory

restrictions or to applications where code density is an issue.

The key idea behind THUMB is that of a super-reduced instruction set. Essentially, the

ARM968E-S processor has two instruction sets:

•Standard 32-bit ARMv5TE set

•16-bit THUMB set

The THUMB set's 16-bit instruction length allows it to approach twice the density of

standard ARM code while retaining most of the ARM's performance advantage over a

traditional 16-bit controller using 16-bit registers. This is possible because THUMB code

operates on the same 32-bit register set as ARM code.

THUMB code can provide up to 65 % of the code size of ARM, and 160 % of the

performance of an equivalent ARM controller connected to a 16-bit memory system.

The ARM968E-S processor is described in detail in the ARM968E-S data sheet Ref. 2.

2.3 On-chip flash memory system

The LPC2917/19 includes a 512 kB or 768 kB flash memory system. This memory can be

used for both code and data storage. Programming of the flash memory can be

accomplished in several ways. It may be programmed in-system via a serial port; e.g.

CAN.

2.4 On-chip static RAM

In addition to the two 16 kB TCMs the LPC2917/19 includes two static RAM memories:

one of 32 kB and one of 16 kB. Both may be used for code and/or data storage. Each

internal SRAM has its own controller, so both memories can be accessed simultaneously

from different AHB system bus layers.

7. Functional description

7.1 Reset, debug, test and power description

7.1.1 Reset and power-up behavior

The LPC2917/19 contains external reset input and internal power-up reset circuits. This

ensures that a reset is extended internally until the oscillators and flash have reached a

stable state. See Section 11 for trip levels of the internal power-up reset circuit1. See

Section 12 for characteristics of the several start-up and initialization times. Table 4 shows

the reset pin.

At activation of the RSTN pin the JTAGSEL pin is sensed as logic LOW. If this is the case

the LPC2917/19 is assumed to be connected to debug hardware, and internal circuits

re-program the source for the BASE_SYS_CLK to be the crystal oscillator instead of the

Low-Power Ring Oscillator (LP_OSC). This is required because the clock rate when

running at LP_OSC speed is too low for the external debugging environment.

7.1.2 Reset strategy

The LPC2917/19 contains a central module, the Reset Generator Unit (RGU) in the

Power, Clock and Reset Control Subsystem (PCRSS), which controls all internal reset

signals towards the peripheral modules. The RGU provides individual reset control as well

as the monitoring functions needed for tracing a reset back to source.
