DESCRIPTION
The
MSC1211/12/13/14
are
completely
integrated
families
of
mixed-signal
devices
incorporating
a
high-resolution delta-sigma (
Σ) ADC, 16-bit DACs,
8-channel multiplexer, burnout detect current sources,
selectable buffered input, offset DAC, Programmable Gain
Amplifier (PGA), temperature sensor, voltage reference,
8-bit microcontroller, Flash Program Memory, Flash Data
Memory, and Data SRAM, as shown in Figure 8.
On-chip
peripherals
include
an
additional
32-bit
accumulator, an SPI-compatible serial port with FIFO, dual
USARTs, multiple digital input/output ports, a watchdog
timer, low-voltage detect, on-chip power-on reset, 16-bit
PWM, breakpoints, brownout reset, three timer/counters,
and a system clock divider. The MSC1211 and MSC1213
also contain a hardware I2C peripheral.
The devices accept low-level differential or single-ended
signals directly from a transducer. The ADC provides 24
bits of resolution and 24 bits of no-missing-code
performance using a Sinc3 filter with a programmable
sample rate. The ADC also has a selectable filter that
allows for high-resolution, single-cycle conversion.
The
microcontroller
core
is
8051
instruction
set
compatible. The microcontroller core is an optimized 8051
core that executes up to three times faster than the
standard 8051 core, given the same clock source. This
design makes it possible to run the devices at a lower
external
clock
frequency
and
achieve
the
same
performance at lower power than the standard 8051 core.
The MSC1211/12/13/14 allow users to uniquely configure the
Flash and SRAM memory maps to meet the needs of their
applications. The Flash is programmable down to 2.7V using
both serial and parallel programming methods. The Flash
endurance is 100k Erase/Write cycles. In addition, 1280
bytes of RAM are incorporated on-chip.
The parts have separate analog and digital supplies, which
can be independently powered from 2.7V to +5.25V.
At +3V operation, the power dissipation for each part is
typically less than 4mW. The MSC1211/12/13/14 are all
available in a TQFP-64 package.
The MSC1211/12/13/14 are designed for high-resolution
measurement applications in smart transmitters, industrial
process control, weigh scales, chromatography, and
portable instrumentation.
