C8051F023-GQ

C8051F02x Microcontrollers, Silicon LabsThe Silicon Labs C8051F02x are highly integrated mixed-signal microcontrollers MCU with two separate high-speed ADC subsystems. Their two separate 12-bit DACs, on-chip VDD monitor, Watchdog Timer and clock oscillator combine to make the C8051F02x devices standalone System-on-Chip solutions. Enable, disable and configure all the analogue and digital peripherals using the firmware. Flash memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. They are specified for 2.7 V to 3.6 V operation over the industrial temperature range -45°C to +85°C. The C8051F020/2 are available in a 100-pin TQFP package. The C8051F021/3 are available in a 64-pin TQFP package.\- 8051-compatible CIP-51 microcontroller core up to 25 MIPS \- In-system, full-speed, non-intrusive debug interface on-chip \- 12-bit C8051F020/1 or 10-bit C8051F022/3 100 ksps 8-channel ADC with PGA and analogue multiplexer \- 8-bit ADC 500 ksps 8-channel ADC with PGA and analogue multiplexer \- Two 12-bit DACs with programmable update scheduling \- 64 kB of in-system programmable FLASH memory \- 4352 4096 + 256 bytes of on-chip RAM \- External Data Memory Interface with 64 kB address space \- SPI, SMBus/I2C, and two UART serial interfaces implemented in hardware \- 64 digital I/O pins C8051F020/2 or 32 digital I/O pins C8051F021/3 \- Five general purpose 16-bit Timers \- Programmable Counter/Timer Array with five capture/compare modules \- On-chip Watchdog Timer, VDD Monitor, and Temperature Sensor ### 8051 微控制器，Silicon Labs
