LPC2114FBD64 Single-chip 16/32-bit microcontrollers 128/256 kB ISP/IAP Flash with 10-bit ADC LQFP64 spot stock

Product Descriptions

The LPC2114/LPC2124 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 128/256 kilobytes (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

With their compact 64 pin package, low power consumption, various 32-bit timers, 4-channel 10-bit ADC, PWM channels and 46 GPIO lines with up to 9 external interrupt pins these microcontrollers are particularly suitable for industrial control, medical systems, access control and point-of-sale. With a wide range of serial communications interfaces, they are also very well suited for communication gateways, protocol converters and embedded soft modems as well as many other general-purpose applications.

Product Features

■ 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.

■ 16 kB on-chip Static RAM.

■ 128/256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator enables high speed 60 MHz operation.

■ 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.

■ EmbeddedICE-RT interface enables breakpoints and watch points. Interrupt service routines can continue to execute whilst the foreground task is debugged with the on-chip RealMonitor™ software.

■ Embedded Trace Macrocell™ enables non-intrusive high speed real-time tracing of instruction execution.

■ Four channel 10-bit A/D converter with conversion time as low as 2.44 µs.

■ Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog.

■ Multiple serial interfaces including two UARTs (16C550), Fast I2C (400 kbits/s) and two SPIs™.

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

■ Vectored Interrupt Controller with configurable priorities and vector addresses.

■ Up to forty-six 5 V tolerant general purpose I/O pins. Up to nine edge or level sensitive external interrupt pins available.

■ On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.

■ Two low power modes, Idle and Power-down.

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

■ Individual enable/disable of peripheral functions for power optimization.

■ Dual power supply:

◆ CPU operating voltage range of 1.65 V to 1.95 V (1.8 V ±0.15 V).

◆ I/O power supply range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O pads.16/32-bit ARM7TDMI-S processor.
