LPC2104/2105/2106
Single-chip 32-bit microcontrollers; 128 kB ISP/IAP Flash with
64 kB/32 kB/16 kB RAM
Rev. 04 — 05 February 2004 Product data
1. General description
The LPC2104, 2105 and 2106 are based on a 16/32 bit ARM7TDMI-S CPU with
real-time emulation and embedded trace support, together with 128 kbytes (kB) of
embedded high speed flash memory. A 128 bit wide memory interface and a unique
accelerator architecture enable 32 bit code execution at 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, these microcontrollers are ideal for
applications where miniaturization is a key requirement, such as access control and
point-of-sale. With a wide range of serial communications interfaces and on-chip
SRAM options up to 64 kilobytes, they are 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, PWM channels and 32 GPIO lines make these microcontrollers particularly
suitable for industrial control and medical systems.
2. Features
2.1 Key features
a73 16/32 bit ARM7TDMI-S processor.
a73 16/32/64 kB on-chip Static RAM.
a73 128 kB on-chip Flash Program Memory. 128 bit wide interface/accelerator
enables high speed 60 MHz operation.
a73 In-System Programming (ISP) and In-Application Programming (IAP) via on-chip
boot-loader software. Flash programming takes 1 ms per 512 byte line. Single
sector or full chip erase takes 400 ms.
a73 Vectored Interrupt Controller with configurable priorities and vector addresses.
a73 EmbeddedICE-RT interface enables breakpoints and watchpoints. Interrupt
service routines can continue to execute whilst the foreground task is debugged
with the on-chip RealMonitor software.
a73 Embedded Trace Macrocell enables non-intrusive high speed real-time tracing of
instruction execution.
a73 Multiple serial interfaces including two UARTs (16C550), Fast I
2
C (400 kbits/s)
and SPI.
a73 Two 32-bit timers (7 capture/compare channels), PWM unit (6 outputs), Real Time
Clock and Watchdog.
a73 Up to thirty-two 5 V tolerant general purpose I/O pins in a tiny LQFP48
(7 × 7mm
2
) package.
