ARM7TDMI-S microcontroller in a tiny LQFP64 package.
kB of on-chip static RAM
kB of on-chip Flash program. 128-bit wide interface/accelerator
enables high speed 60 MHz operation.
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
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.
Trace Macrocell enables non-intrusive high speed real-time
tracing of instruction execution.
