Chip Feature
overview:
- 16/32-bit
ARM7TDMI-S microcontroller in a LQFP144 package.
- 16
kB on-chip Static RAM and 128/256 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.
- EmbeddedICE-RT
and Embedded Trace interfaces offer real-time debugging
with the on-chip RealMonitor software as well as high speed
real-time tracing of instruction execution.
- Eight
channel 10-bit A/D converter with conversion time as low
as 2.44 us.
- Two
32-bit timers (with 4 capture and 4 compare channels), PWM
unit (6 outputs), Real Time Clock and Watchdog.
- Multiple
serial interfaces including two UARTs (16C550), Fast I²C
(400 kbits/s) and two SPIsTM.
- Vectored
Interrupt Controller with configurable priorities and vector
addresses.
- Configurable
external memory interface with up to four banks, each up
to 16 Mb and 8/16/32 bit data width.
- Up
to 112 general purpose I/O pins (5 V tolerant). Up to 9
edge or level sensitive external interrupt pins available.
- 60
MHz maximum CPU clock available from programmable on-chip
Phase-Locked Loop.
- 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 +-0.15 V).
-
I/O power supply range of 3.0 V to 3.6 V (3.3 V +-10pct)
with 5 V tolerant I/O pads. 16/32-bit ARM7TDMI-S processor.
