The CR16MBR5 device has 32K bytes of ROM program
memory, 3K bytes of static RAM, two USARTs, two 16-bit
multi-function timers, one SPI/MICROWIRE-PLUS serial
interface, a 12-channel A/D converter, two analog compara-
tors, WATCHDOG protection mechanism, and up to 56
general-purpose I/O pins.
General Description
(Continued)
The CR16MBR5 device operates with a high-frequency crys-
tal as the main clock source and either the prescaled main
clock source or with a low frequency (32.768 kHz) oscillator
in Power Save mode. The device supports several Power
Save modes which are combined with multi-source interrupt
and wake-up capabilities.
This device also has a Versatile Timer Unit (VTU) with four
timer sub-systems, a CAN interface, and ACCESS.bus syn-
chronous serial bus interface.
Powerful cross-development tools are available from Nation-
al Semiconductor and third party suppliers to support the de-
velopment and debugging of application software for the
CR16MBR5. These tools let you program the application
software in C and are designed to take full advantage of the
CompactRISC architecture.
