General description

The LPC2131/32/34/36/38 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combine 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 and benefits

2.1 Enhancements brought by LPC213x/01 devices

? Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original

LPC213x. They also allow for a port pin to be read at any time regardless of its

function.

? Dedicated result registers for ADC(s) reduce interrupt overhead.

? UART0/1 include fractional baud rate generator, auto-bauding capabilities and

handshake flow-control fully implemented in hardware.

? Additional BOD control enables further reduction of power consumption.

2.2 Key features common for LPC213x and LPC213x/01

? 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 or HVQFN64 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 Programming/In-Application Programming (ISP/IAP) via on-chip bootloader software. Single flash sector or full chip erase in 400 ms and programming of 256 B 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.
