LPC2142/2148
Single-chip 16/32-bit microcontrollers; 64/512 kB flash with
ISP/IAP, USB 2.0 full-speed device, 10-bit ADC and DAC
Rev. 01 — 22 June 2005
Preliminary data sheet
1. General description
The LPC2142/2148 microcontrollers are based on a 32/16-bit ARM7TDMI-S CPU with
real-time emulation and embedded trace support, that combines the microcontroller with
64 kB and 512 kB of embedded high-speed flash memory. A 128-bit wide memory
interface and a unique accelerator architecture enable 32-bit code execution at the
maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode
reduces code by more than 30 % with minimal performance penalty.
Due to their tiny size and low power consumption, LPC2142/2148 are ideal for
applications where miniaturization is a key requirement, such as access control and
point-of-sale. A blend of serial communications interfaces ranging from a USB 2.0
Full-speed device, multiple UARTs, SPI, SSP to I2C-bus and on-chip SRAM of
16 kB/40 kB, make these devices very well suited for communication gateways and
protocol converters, soft modems, voice recognition and low end imaging, providing both
large buffer size and high processing power. Various 32-bit timers, single or dual 10-bit
ADC(s), 10-bit DAC, PWM channels and 45 fast GPIO lines with up to nine edge or level
sensitive external interrupt pins make these microcontrollers particularly suitable for
industrial control and medical systems.

LPC2142/2148
Single-chip 16/32-bit microcontrollers
In case of LPC2148 only, an 8 kB SRAM block intended to be utilized mainly by the USB
can also be used as a general purpose RAM for data storage and code storage and
execution.
6.4 Memory map
The LPC2142/2148 memory map incorporates several distinct regions, as shown in
Figure 3.
In addition, the CPU interrupt vectors may be remapped to allow them to reside in either
flash memory (the default) or on-chip static RAM. This is described in Section 6.22
“System control”.

6.5 Interrupt controller
The VIC accepts all of the interrupt request inputs and categorizes them as Fast Interrupt
Request (FIQ), vectored Interrupt Request (IRQ), and non-vectored IRQ as defined by
programmable settings. The programmable assignment scheme means that priorities of
interrupts from the various peripherals can be dynamically assigned and adjusted.
