LPC2105 Single-chip 32-bit microcontrollers; 128 kB ISP/IAP Flash with 64 kB/32 kB/16 kB RAM
Key features
n 16/32 bit ARM7TDMI-S processor.
n 16/32/64 kB on-chip Static RAM.
n 128 kB on-chip Flash Program Memory. 128 bit wide interface/accelerator
enables high speed 60 MHz operation.
n 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.
n Vectored Interrupt Controller with conÞgurable priorities and vector addresses.
n 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.
n Embedded Trace Macrocell enables non-intrusive high speed real-time tracing of
instruction execution.
n Multiple serial interfaces including two UARTs (16C550), Fast I2C (400 kbits/s)
and SPI“.
n Two 32-bit timers (7 capture/compare channels), PWM unit (6 outputs), Real Time
Clock and Watchdog.
n Up to thirty-two 5 V tolerant general purpose I/O pins in a tiny LQFP48
(7 ´ 7 mm2) package.
