New features implemented in LPC2104/2105/2106/01 devices
Fast GPIO port enables port pin toggling up to 3.5 times faster than the
original device and also allows for a port pin to be read at any time
regardless of its function.
UART 0/1 include fractional baud rate generator, autobauding capabilities,
and handshake flow-control fully implemented in hardware.
Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire
- SPI programmable data length and mode enhancement.
Diversified Code Read Protection (CRP) enables different security levels
to be implemented.
- General purpose timers can operate as external event counters.
Key common features
- 16/32-bit Arm7TDMI-S™ processor.
- 16/32/64 kB on-chip static RAM.
128 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 bootloader software. Flash programming takes 1 ms per 512 B line.
Single sector or full chip erase takes 400 ms.
Vectored Interrupt Controller with configurable priorities and vector
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.
Multiple serial interfaces including two UARTs (16C550), Fast I²C-bus
(400 kbit/s), and SPI.
Two 32-bit timers (7 capture/compare channels), PWM unit (6 outputs), Real
Time Clock and Watchdog.
Up to thirty-two 5 V tolerant general purpose I/O pins in a tiny LQFP48 (7
mm x 7 mm) package.
60 MHz maximum CPU clock available from programmable on-chip Phase-Locked
Loop with settling time of 100 us.
The on-chip crystal oscillator should have an operating range of 1 MHz to
- 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 +- 8.3 pct).
I/O power supply range of 3.0 V to 3.6 V (3.3 V +- 10 pct) with 5 V
tolerant I/O pads.
