philips semiconductors lpc2114/LPC2124 single-chip 16/32-bit microcontrollers product data rev. 03 22 december 2004 9 of 34 9397 750 13145 ? koninklijke philips electronics n.v. 2004. all rights reserved. 6. functional description details of the lpc2114/LPC2124 systems and peripheral functions are described in the following sections. 6.1 architectural overview the arm7tdmi-s is a general purpose 32-bit microprocessor, 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 microprogrammed complex instruction set computers. this simplicity results in a high instruction throughput and impressive real-time interrupt response from a small and cost-effective processor core. pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously. typically, while one instruction is being executed, its successor is being decoded, and a third instruction is being fetched from memory. the arm7tdmi-s processor also employs a unique architectural strategy known as thumb, which makes it ideally suited to high-volume applications with memory restrictions, or applications where code density is an issue. the key idea behind thumb is that of a super-reduced instruction set. essentially, the arm7tdmi-s processor has two instruction sets: ? the standard 32-bit arm set. ? a 16-bit thumb set. the thumb sets 16-bit instruction length allows it to approach twice the density of standard arm code while retaining most of the arms performance advantage over a traditional 16-bit processor using 16-bit registers. this is possible because thumb code operates on the same 32-bit register set as arm code. thumb code is able to provide up to 65 % of the code size of arm, and 160 % of the performance of an equivalent arm processor connected to a 16-bit memory system. 6.2 on-chip flash program memory the lpc2114/LPC2124 incorporate a 128 kb and 256 kb flash memory system respectively. this memory may be used for both code and data storage. programming of the flash memory may be accomplished in several ways. it may be programmed in system via the serial port. the application program may also erase and/or program the flash while the application is running, allowing a great degree of ?exibility for data storage ?eld ?rmware upgrades, etc. when on-chip bootloader is used, 120/248 kb of flash memory is available for user code. the lpc2114/LPC2124 flash memory provides a minimum of 100,000 erase/write cycles and 20 years of data retention. on-chip bootloader (as of revision 1.60) provides code read protection (crp) for the lpc2114/LPC2124 on-chip flash memory. when the crp is enabled, the jtag debug port and isp commands accessing either the on-chip ram or flash memory
