CRD5376
22 DS612RD2
CRD5376, as an input from the microcontroller to initiate data transactions on command or from the
MCLK/2 clock to initiate data transactions automatically as soon as they are available from the digital filter.
2.3.2 Microcontroller
Included on CRD5376 is an 8051-type microcontroller with integrated hardware SPI and USB interfaces.
This C8051F320 microcontroller is a product of Silicon Laboratories (http://www.silabs.com/). Key fea-
tures of the C8051F320 microcontroller are:
8051 compatibility - uses industry standard 8051 software development tools
In-circuit debugger - software development on the target hardware
Internal memory - 16k flash ROM and 2k static RAM included on-chip
Multiple serial connections - SPI, USB, I2C, and UART
High performance - 25 MIPS maximum
Low power - 0.6 mA @ 1 MHz w/o USB, 9 mA @ 12 MHz with USB
Small size - 32 pin LQFP package, 9mm x 9mm
Industrial temperature - full performance (including USB) from -40 C to +85 C
Internal temperature sensor - with range violation interrupt capability
Internal timers - four general purpose plus one extended capability
Power on reset - can supply a reset signal to external devices
Analog ADC - 10 bit, 200 ksps SAR with internal voltage reference
Analog comparators - arbitrary high/low voltage compare with interrupt capability
The exact use of the microcontroller features is controlled by embedded firmware.
