C8051F017 - 25MHz Mixed-Signal 8051 MCU | Silicon Labs
MPN: C8051F017 ✓ פעילC8051F017 סקירה
A mixed-signal microcontroller, or MCU, integrates a digital processor core, analog converters, memory, and communication peripherals into one semiconductor package. The C8051F017 belongs to the C8051F01x family of 8-bit embedded controllers, combining digital control with ADC and DAC functions. This hierarchy places it within embedded microcontrollers and embedded processors, where compact analog acquisition or waveform generation can reduce the number of external components required by an instrument controller.
Key features include 25MHz operation, 25 MIPS execution, 32KB of ISP Flash, 2.25K x 8 RAM, a 10-bit ADC capable of 100 ksps conversion, and a 12-bit DAC with two channels. Communication and control resources include SPI, SMBus/I2C, UART, four timers, and a programmable counter array. An integrated temperature sensor supports local thermal monitoring, while the 32-LQFP package provides a practical surface-mount option for compact control boards.
Technically, the part combines a deterministic 8-bit control architecture with dedicated analog conversion resources. The 10-bit ADC supports measurements from up to four analog channels at 100 ksps, while the dual 12-bit DAC provides higher-resolution analog output than the ADC resolution. Together with SPI, SMBus/I2C, UART, timers, and the programmable counter array, these blocks support closed-loop sensing, waveform generation, industrial communication, and embedded data acquisition without requiring separate converter ICs.
Typical applications include compact industrial data-acquisition modules, sensor-control systems, programmable instrumentation, laboratory equipment, and temperature-monitored embedded controllers. The ADC can sample external analog signals, the DAC can generate control or test voltages, and the serial interfaces can connect sensors, memory, or host equipment. The integrated temperature sensor is useful for local diagnostics or thermal compensation where an external sensor would add cost and board area.
Designers should confirm the exact device variant, supply operating range, clock configuration, analog input limits, and package pin assignments against the manufacturer datasheet before layout. Decoupling, analog grounding, DAC reference stability, and ADC input conditioning remain critical because the digital control core and precision analog converters share the same device and supply network.
This page consolidates the verified family specifications, sourcing links, package details, and same-family drop-in considerations into one engineering reference. It also highlights where supplied data remains incomplete, allowing designers to distinguish documented facts from parameters that still require direct datasheet verification before schematic approval or PCB release.

יישומים טיפוסיים
C8051F017 מתאים עבור 6 יישוםs: Industrial Sensor Acquisition, Programmable Test and Measurement, Temperature Monitoring and Control, Embedded Control with Analog I/O, Laboratory Automation Equipment, Communications Gateway and Monitor.
Industrial Sensor Acquisition
The C8051F017 fits compact industrial sensor modules because its 10-bit ADC samples up to four channels at 100 ksps while the 25-MIPS 8051 core performs filtering and control calculations in real time. SPI, SMBus/I2C, and UART allow the controller to communicate with sensors, condition electronics, and a supervisory host. The 2.25K x 8 RAM and 32KB ISP Flash support local acquisition logic, while the integrated temperature sensor can provide local thermal compensation or diagnostics. Designers should use conditioned inputs, reference grounding, and supply decoupling appropriate to the selected analog front end.
מומלץ
Programmable Test and Measurement
The C8051F017 is appropriate for programmable instruments that acquire an analog input and produce a controlled analog output. Its 10-bit, four-channel ADC supports monitoring at 100 ksps, while the 12-bit, two-channel DAC provides excitation or reference signals without a separate converter. The 25MHz core can coordinate readings, sequences, and communications, and UART, SPI, and SMBus/I2C support control by a host or instrument controller. Because the supplied data does not specify DAC settling time, output range, or reference accuracy, those limits must be confirmed before defining precision stimulus specifications.
מומלץ
Temperature Monitoring and Control
The C8051F017 supports compact temperature-monitoring systems through its on-chip temperature sensor, 10-bit ADC, and deterministic 25-MIPS control core. External analog channels can monitor thermistors, RTDs, or process signals while firmware performs averaging, calibration, threshold checking, and alarm handling. Four timers and the PCA help maintain periodic sampling and control timing, and UART or SMBus/I2C can report measurements to a controller. The integrated sensor reduces board area, but its calibration, accuracy, and operating range are not supplied here and must be obtained from the manufacturer datasheet before using it as a calibrated reference.
מומלץ
Embedded Control with Analog I/O
The C8051F017 is suitable for embedded controllers that must both measure and influence an analog process. The 10-bit ADC can sample four analog inputs at 100 ksps, and the dual 12-bit DAC can generate control voltages without a separate output converter. At 25MHz and 25 MIPS, the controller can execute acquisition, digital filtering, and supervisory logic, while SPI, SMBus/I2C, and UART connect to external equipment. Four timers and the PCA support deterministic sequencing. Engineers should preserve analog signal integrity through short traces, appropriate grounding, filtering, and verified DAC reference design.
מומלץ
Laboratory Automation Equipment
The C8051F017 can serve as the local controller in compact laboratory automation equipment that coordinates sensing, output generation, and host communication. Its four-channel 10-bit ADC at 100 ksps supports data acquisition, while the two-channel 12-bit DAC provides programmable analog excitation. SPI and SMBus/I2C support peripheral connectivity, UART supports a command interface, and the four timers help coordinate repeatable test sequences. The 32-LQFP package supports compact board construction, and 32KB ISP Flash accommodates embedded control code. Precision accuracy claims require the missing datasheet details for reference voltage, converter linearity, and calibration.
מומלץ
Communications Gateway and Monitor
The C8051F017 can act as a small communications gateway or monitoring controller when a design needs local analog awareness in addition to serial connectivity. UART supports host links, while SPI and SMBus/I2C connect sensors, converters, or external memory. Its 25-MIPS core can maintain protocol handling, acquisition, filtering, and fault logging concurrently, and the integrated temperature sensor adds local health information. The 32KB ISP Flash and 2.25K x 8 RAM are suitable for focused embedded firmware, subject to final memory budgeting. Protocol timing, oscillator requirements, and peripheral multiplexing must be reviewed in the official pinout before PCB layout.

הערות תכנון
Treat the analog inputs, DAC outputs, reference circuitry, and digital supply return as separate layout domains. Place the MCU's decoupling capacitors at the supply pins and keep analog traces short and away from high-current switching nodes. Because the supplied excerpts do not provide the complete pin map or analog layout guidance, use the package drawing and recommended application layout in the official C8051F0xx datasheet before routing.
Condition every external ADC input so its voltage remains within the datasheet limits and presents suitable source impedance to the sampling circuit. The 100-ksps figure defines conversion capability, but achievable accuracy also depends on acquisition time, source impedance, reference stability, filtering, and layout. Add filtering or buffering where sensor outputs cannot settle adequately during the selected sampling interval.
Do not treat C8051F017, C8051F017-GQ, and other C8051F01x members as automatically interchangeable. The GQ suffix identifies an orderable 32-LQFP option, while related family members may differ in analog channels, DAC features, memory, timers, and peripheral pin assignment. Compare the official package pin table, electrical characteristics, errata, and device revision before reusing an existing PCB or changing production part numbers.
Use the 2.7V to 3.6V supply range as a hard design constraint and verify startup, transient response, and analog-reference behavior across the intended load. Current consumption and thermal limits were not present in the supplied excerpts, so they must not be estimated from the CPU clock alone. Obtain worst-case operating, idle, and reset current from the manufacturer datasheet before selecting the regulator and copper area.
מידע על תאימות
The supplied excerpts do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because this is an industrial embedded MCU and no automotive qualification evidence was supplied.
