1.8.
C8051F41x devices include a cyclic redundancy check unit (CRC0) that can perform a CRC using a 16-bit
or 32-bit polynomial. CRC0 accepts a stream of 8-bit data and outputs a 16-bit or 32-bit result. CRC0 also
has a hardware bit reverse feature for quick data manipulation.
1.9.
C8051F41x devices include an on-chip low dropout voltage regulator (REG0). The input to REG0 at the
V
enabled, the output of REG0 powers the device and drives the V
to power external devices connected to V
1.10. Serial Ports
The C8051F41x Family includes an SMBus/I2C interface, a full-duplex UART with enhanced baud rate
configuration, and an Enhanced SPI interface. Each of the serial buses is fully implemented in hardware
and makes extensive use of the CIP-51's interrupts, thus requiring very little CPU intervention.
