1. General description
The LPC2131/2132/2134/2136/2138 microcontrollers are based on a 32/16 bit
ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines
the microcontroller with 32 kB, 64 kB, 128 kB, 256 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 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 of 8/16/32 kB, 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, single or dual 10-bit
8 channel ADC(s), 10-bit DAC, PWM channels and 47 GPIO lines with up to nine edge or
level sensitive external interrupt pins make these microcontrollers particularly suitable for
industrial control and medical systems.
2. Features
2.1 Key features
■ 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
■ 8/16/32 kB of on-chip static RAM and 32/64/128/256/512 kB of on-chip Flash program
memory. 128 bit wide interface/accelerator enables high speed 60 MHz operation.
■ In-System/In-Application Programming (ISP/IAP) via on-chip boot-loader software.
Single Flash sector or full chip erase in 400 ms and programming of 256 bytes in 1 ms.
■ EmbeddedICE RT and Embedded Trace interfaces offer real-time debugging with the
on-chip RealMonitor software and high speed tracing of instruction execution.
■ One (LPC2131/32) or two (LPC2134/36/38) 8 channel 10-bit A/D converters provides
a total of up to 16 analog inputs, with conversion times as low as 2.44 µs per channel.
■ Single 10-bit D/A converter provides variable analog output (LPC2132/34/36/38).
■ Two 32-bit timers/external event counters (with four capture and four compare
channels each), PWM unit (six outputs) and watchdog.
■ Low power Real-time clock with independent power and dedicated 32 kHz clock input.
■ Multiple serial interfaces including two UARTs (16C550), two Fast I
2
C-bus (400 kbit/s),
SPI and SSP with buffering and variable data length capabilities.
■ Vectored interrupt controller with configurable priorities and vector addresses.
