Each microcontroller is also equipped with up to two 10-bit
A/D converters and a 10-bit D/A converter.
Multiple serial communications interfaces increase design
flexibility, provide larger buffer size, and deliver higher
processing power. There are two 16C550 UARTs, two Fast
I
capabilities for buffering and variable data length).
There are two 32-bit timers (each with four capture and
compare channels), a PWM unit with six outputs, a real-time
clock, and a Watchdog timer.
For debugging, each device supports real-time emulation
and embedded trace support and has an integrated vectored
interrupt controller (VIC). Also, for compatibility with existing
tools, each device uses the standard ARM test/debug JTAG
interface.
Other features include 45 Fast I/O pins (5-V tolerant) with
switching up to 15 MHz, and an operating temperature range
of -40 to 85 °C.
