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.

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 I2C-bus (400 kbit/s), SPI and SSP with buffering and variable data length capabilities.

■ Vectored interrupt controller with configurable priorities and vector addresses.

■ Up to 47 5 V tolerant general purpose I/O pins in tiny LQFP64 package.

■ Up to nine edge or level sensitive external interrupt pins available.

■ 60 MHz maximum CPU clock available from programmable on-chip PLL with settling time of 100 μs.

■ On-chip integrated oscillator operates with external crystal in range of 1 MHz to 30 MHz and with 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 down for additional power optimization.

■ Processor wake-up from Power-down mode via external interrupt or BOD.

■ Single power supply chip with 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.
