Single chip microprocessor based on ARM7 core.
Key features
16/32 bit ARM7TDMI-S processor.
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 boot-loader software. Flash programming takes 1 ms per 512 byte line. Single sector or full chip erase takes 400 ms.
Vectored Interrupt Controller with configurable priorities and vector addresses.
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 (400 kbits/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 x 7 mm2) package.
60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop with settling time of 100 us.
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 +- 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.
