Part: LPC2138
Category:
Microcontrollers
-> 16/32 bit
Description: Single-chip 16/32-bit microcontroller<<<>>>The LPC2131/2132/2138 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 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 pct 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. <<<>>><<<>>> <<<>>>Features<<<>>>Key features <<<>>>16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package. <<<>>>8/16/32 kB of on-chip static RAM and 64/512 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 (LPC2131/2132) or two (LPC2138) 8 channel 10-bit A/D converters provides a total of up to 16 analog inputs, with conversion times as low as 2.44 ms per channel. <<<>>>Single 10-bit D/A converter provides variable analog output. (LPC2132/2138 only) <<<>>>Two 32-bit timers/counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog. <<<>>>Real-time clock equipped with independent power and clock supply permitting extremely low power consumption in power-save modes. <<<>>>Multiple serial interfaces including two UARTs (16C550), two Fast I˛C-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 us. <<<>>>On-chip crystal oscillator with an operating range of 1 MHz to 30 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. <<<>>>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 pct) with 5 V tolerant I/O pads.
