Furthermore, improvements were made to peripheral
features that off-load processing from the core, and the
user, to further improve efficiency. For instance, the SPI
interface uses a FIFO, which allows the SPI interface to
transmit and receive data with minimum overhead needed
from the core. Also, a 32-bit accumulator was added to
significantly reduce the processing overhead for multiple
byte data from the ADC or other sources. This allows for
32-bit
addition,
subtraction
and
shifting
to
be
accomplished in a few instruction cycles, compared to
hundreds of instruction cycles executed through software
implementation.
Family Device Compatibility
The hardware functionality and pin configuration across
the MSC1211/12/13/14 families are fully compatible. To
the user, the only differences between family members are
the memory configuration, the number of DACs, and the
availability of I2C for the MSC1211 and MSC1213. This
design makes migration between family members simple.
This gives the user the ability to add or subtract software
functions and to freely migrate between family members.
Thus, the MSC1211/12/13/14 can become a standard
device used across several application platforms.
Family Development Tools
The MSC1211/12/13/14 are fully compatible with the
standard 8051 instruction set. This compatibility means
that
users
can
develop
software
for
the
MSC1211/12/13/14 with their existing 8051 development
tools. Additionally, a complete, integrated development
environment is provided with each demo board, and
third-party developers also provide support.
Power-Down Modes
The MSC1211/12/13/14 can each power several of the
on-chip peripherals and put the CPU into Idle mode. This
is accomplished by shutting off the clocks to those
sections, as shown in Figure 11.
