C8051F061 - 25MHz Mixed-Signal MCU | Silicon Labs
部品番号: C8051F061 ✓ 生産中C8051F061 概要
A mixed-signal microcontroller is an embedded semiconductor that integrates digital processing with analog conversion and comparison functions. The C8051F061 belongs to the C8051F06x family and combines an 8051-compatible embedded processing core with on-chip ADC, DAC, comparator, timer, serial-interface, and communication resources. This mixed-signal MCU category reduces the need for separate analog and digital ICs when a product must measure, generate, or monitor analog signals.
Key features include 64 KB of in-system-programmable flash, 4.25K x 8 RAM, five timers, a watchdog timer, and the Programmable Counter Array. Communication and peripheral resources include SPI, SMBus, I2C, two UARTs, and CAN 2.0B. The analog subsystem includes a 16-bit, one-channel ADC operating at 1 Msps, an eight-channel 10-bit ADC, a 12-bit, two-channel DAC, and three analog comparators. An on-chip temperature sensor is also listed for the device.
The 25 MHz implementation delivers up to 25 MIPS while retaining the established 8051 instruction set and mixed-signal integration characteristic of the C8051F06x family. The 24 available digital I/O lines make the device appropriate for compact embedded controllers that need several serial interfaces and analog measurements without relying on a large external component count. The 64-pin TQFP package exposes the mixed-signal resources and digital interfaces on a surface-mount footprint.
Typical uses include industrial sensor acquisition, process-control equipment, CAN-connected embedded instrumentation, data acquisition modules, and compact control panels. In these systems, the ADC can sample analog inputs, the DAC can generate reference or control voltages, and the UART, SPI, I2C, SMBus, and CAN interfaces can connect local sensors, actuators, and supervisory electronics. The integrated temperature sensor can also support local thermal monitoring where its accuracy is appropriate for the application.
Designers should treat the 2.7 V to 3.6 V supply range as a hard design constraint and provide decoupling close to the device pins. Analog and digital grounds, analog inputs, and high-impedance nodes require careful layout to limit noise and offset errors. Firmware migration should also verify peripheral availability and pin multiplexing for the selected C8051F06x variant rather than assuming that every family member has identical resources.
This page combines verified distributor specifications, availability information, same-family drop-in candidates, package details, and practical design guidance. It adds engineering-focused comparisons that are not normally presented together on a distributor product page, helping designers evaluate the C8051F061 for embedded control, analog measurement, and communication applications.

主な用途
C8051F061 の用途: 6 件s: Industrial Sensor Acquisition, CAN-Connected Process Control, Data Acquisition Module, Local Temperature Monitoring, Automated Test Equipment, Embedded Communication Controller.
Industrial Sensor Acquisition
The C8051F061 fits industrial sensor-acquisition equipment because it combines a 25 MIPS 8051 core with a 16-bit, one-channel, 1 Msps ADC and an eight-channel 10-bit ADC in one 64-TQFP device. The higher-resolution channel can be used for precision measurements, while the multichannel 10-bit converter can monitor several slower sensor inputs. Two UARTs, SPI, I2C, and SMBus provide local connections to sensors and service interfaces without requiring separate interface ICs. The principal design consideration is keeping analog routing away from switching and digital return currents.
おすすめ
CAN-Connected Process Control
The C8051F061 is suitable for compact process-control modules because it combines CAN 2.0B, two UARTs, five timers, and analog measurement resources in one 2.7 V to 3.6 V device. A controller can use the 16-bit ADC for a critical process variable, the 12-bit two-channel DAC for actuator or reference outputs, and the comparators for fast threshold detection. Its 64 KB of flash and 4.25K x 8 RAM support local control logic and communications buffering. Firmware should confirm CAN timing, interrupt requirements, and peripheral multiplexing against the device documentation.
おすすめ
Data Acquisition Module
The C8051F061 can serve as the core of a compact data-acquisition module where analog input count, output generation, and communications must share a small package. Its 16-bit, one-channel, 1 Msps ADC supports high-resolution waveform or sensor capture, while the eight-channel 10-bit ADC supports multichannel monitoring. The 12-bit, two-channel DAC can generate excitation or calibration signals, and SPI, I2C, SMBus, UART, and CAN allow the module to transfer data to a host. Layout must preserve analog grounding and provide local supply decoupling.
おすすめ
Local Temperature Monitoring
The C8051F061's integrated temperature sensor makes it useful for local thermal supervision in embedded instruments and industrial controllers. The sensor can complement the 16-bit or 10-bit ADCs used for external analog channels, while three comparators support threshold-based monitoring and five timers provide periodic measurement intervals. The MCU can report temperature through a selected UART, SPI, I2C, SMBus, or CAN connection. Because on-chip temperature readings can be influenced by package dissipation and PCB thermal paths, calibration and a representative thermal test are necessary before using them for safety-critical decisions.
おすすめ
Automated Test Equipment
The C8051F061 is well matched to automated test equipment that must measure analog signals and coordinate several digital interfaces. The 16-bit, one-channel, 1 Msps ADC provides a high-resolution measurement path, the 12-bit, two-channel DAC can create test stimuli, and the three comparators can perform limit detection. Five timers and the Programmable Counter Array support timing-intensive routines, while UART and CAN provide results reporting and fixture control. The 64-TQFP footprint is useful for higher-pin-count mixed-signal designs, although analog calibration and reference design review remain essential.
おすすめ
Embedded Communication Controller
The C8051F061 supports embedded communication-controller designs that need more than one wired interface. Two UARTs can serve console or peripheral links, SPI can support a higher-speed local bus, and I2C and SMBus can connect sensors and configuration devices. CAN 2.0B adds a standardized option for industrial networking, while the watchdog timer supports recovery from unexpected firmware or peripheral faults. Its 25 MHz 8051 core and 64 KB flash provide adequate resources for protocol handling, although timing-critical designs should verify clock accuracy, interrupt latency, and bus capacitance.

設計ノート
Place input, output, and analog-reference decoupling capacitors close to their associated C8051F061 pins, with the shortest possible ground-return paths. The verified operating range is 2.7 V to 3.6 V, so a stable 3.3 V rail is the normal design target. Keep switching-current loops away from the 16-bit and 10-bit ADC inputs, and route analog grounds according to the manufacturer's mixed-signal layout guidance rather than using an arbitrary split-plane arrangement.
Do not substitute a generic 64-pin pinout for the published C8051F061 assignment. Verify analog inputs, comparator pins, oscillator connections, programming pins, reset behavior, and alternate digital functions in the Silicon Laboratories C8051F06x datasheet. The supplied search data confirms the 64-TQFP package and 24 available digital I/O lines but does not provide the complete numbered pin table, so schematic and PCB design must be checked against the official package-specific pinout.
Avoid assuming that adjacent C8051F06x MPNs are firmware- and pin-compatible without checking their variant tables. The family includes 24-I/O and 59-I/O groups, and differences in ADC, DAC, comparator, temperature-sensor, or communications resources can change both board routing and driver code. Treat same-package family members as candidates rather than automatic replacements, then review startup code, SFR addresses, peripheral availability, and interrupt-vector assignments.
コンプライアンス情報
The supplied verified snippets mention RoHS and REACH only in a generic third-party comparison context and do not provide extractable compliance declarations for C8051F061. Compliance fields are therefore recorded as unknown rather than inferred.
