Chapter 1: Introductory information
• 60 MHz maximum CPU clock available from programmable on-chip PLL with settling
time of 100 s.
• On-chip integrated oscillator operates with an external crystal in range from 1 MHz to
30 MHz and with an external oscillator up to 50 MHz.
• Power saving modes include Idle and Power-down.
• Individual enable/disable of peripheral functions as well as peripheral clock scaling for
additional power optimization.
• Processor wake-up from Power-down mode via external interrupt, USB, Brown-Out
Detect (BOD) or Real-Time Clock (RTC).
• Single power supply chip with Power-On Reset (POR) and BOD circuits:
– CPU operating voltage range of 3.0 V to 3.6 V (3.3 V 10 %) with 5 V tolerant I/O
pads.
1.3 Applications
• Industrial control
• Medical systems
• Access control
• Point-of-sale
• Communication gateway
• Embedded soft modem
• General purpose applications
1.4 Device information
[1] While the USB DMA is the primary user of the additional 8 kB RAM, this RAM is also accessible at any time by the CPU as a general
purpose RAM for data and code storage.
1.5 Architectural overview
The LPC2141/2/4/6/8 consists of an ARM7TDMI-S CPU with emulation support, the
ARM7 Local Bus for interface to on-chip memory controllers, the AMBA Advanced
High-performance Bus (AHB) for interface to the interrupt controller, and the ARM
