MSC1200 Characteristics
1.1 MSC1200 Characteristics
The MSC1200 is a precision 24-bit delta-sigma (∆Σ) analog-to-digital convert-
er with an 8051 microcontroller and up to 8K of flash memory. It has eight fully
differential or single-ended analog input channels. The delta-sigma architec-
ture employed in the MSC1200 enables the device to achieve 22 bits of effec-
tive resolution (0.45ppm RMS noise) at a data rate of 10Hz. It can be pro-
grammed for other data rates up to 1 kHz that have lower effective resolution.
In addition to the standard 8051 peripherals and functions, the MSC1200
includes a 32-bit accumulator, basic SPI/I
4/8K data flash memory, 1,280 bytes of data RAM, UART and dual DPTR
registers.
The MSC1200 has an enhanced 8051 core which only requires four clock
cycles per machine cycle. It has extra timers as well as watchdog, brownout
and low voltage detect circuits. Additionally, it features power management
control and hardware breakpoint registers.
