C8051F007 - 25MHz Mixed-Signal 32KB Flash MCU | Silicon Labs
部品番号: C8051F007 ✗ 生産終了C8051F007 概要
A mixed-signal microcontroller is an embedded semiconductor that combines a digital processor core with analog conversion and comparison functions. The C8051F007 belongs to the 8051 microcontroller hierarchy: its C8051F00x family architecture combines a legacy-compatible 8-bit processing core with flash memory, on-chip peripherals, and mixed-signal conversion blocks. This integration reduces the component count and board area required for designs that measure analog inputs and generate controlled analog outputs.
Key features include 25 MIPS processing performance, 32 KB of ISP flash, 2.25 KB of RAM, a four-channel 12-bit ADC capable of 100 ksps conversion, and a dual-channel 12-bit DAC. The 2.7 V to 3.6 V operating range suits low-voltage embedded systems, while eight I/O pins provide digital control and status signaling. The integrated comparator and temperature sensor extend the device beyond basic data acquisition, enabling local threshold detection and temperature-oriented designs without additional external ICs.
The enhanced 8051 core provides a practical balance between processing capability and design familiarity. ISP flash supports programming in circuit, while integrated analog peripherals reduce conversion-system complexity. At 25 MIPS, the C8051F007 is suitable for supervisory control loops, signal conditioning, sensor interfaces, and compact industrial or instrumentation systems. Because this is an 8-bit MCU with limited RAM, software should use the available memory efficiently and avoid treating it as a high-bandwidth signal-processing platform.
Typical uses include industrial process-control modules, temperature-monitoring instruments, motor and actuator controllers, laboratory measurement equipment, sensor conditioning, and compact embedded data-acquisition systems. The ADC supports four analog inputs, while the DAC can generate two controlled analog outputs. These resources make the MCU appropriate for systems where a single device must supervise digital logic while also acquiring measurements and driving analog control signals.
Designers should verify the complete pinout and analog operating details in the manufacturer C8051F0xx datasheet before layout because the verified source set does not provide a reliable numbered pin list. Analog inputs, DAC outputs, supply pins, oscillator connections, and programming signals also require normal signal-integrity, grounding, and decoupling practices. The 2.7 V minimum supply and 3.6 V maximum supply must be respected throughout startup, measurement, and output conditions.
This product page combines the verified 25 MIPS, 32 KB flash, 12-bit ADC, DAC, comparator, temperature-sensor, package, supply-voltage, RAM, and I/O information with same-family replacement guidance and practical selection notes. It also distinguishes verified facts from parameters that still require confirmation from the full manufacturer datasheet.

主な用途
C8051F007 の用途: 6 件s: Industrial Process-Control Module, Temperature-Monitoring Instrument, Sensor-Conditioning and Data Acquisition, Motor and Actuator Controller, Laboratory Measurement Equipment, Programmable Analog Signal Generator.
Industrial Process-Control Module
The C8051F007 fits compact industrial process-control modules because it combines a 25 MIPS 8051 core with a four-channel, 12-bit ADC sampling at up to 100 ksps. The MCU can acquire multiple sensor channels, execute control logic, and use its eight digital I/O pins to operate relays, indicators, or actuator interfaces. Its 2.7 V to 3.6 V operating range is suitable for regulated low-voltage industrial electronics. The integrated comparator can support direct threshold detection, while the two-channel 12-bit DAC can generate control or reference signals. Designers should allow appropriate analog settling time, use a quiet supply for conversion accuracy, and validate isolation or protection requirements for external industrial inputs.

Temperature-Monitoring Instrument
The C8051F007 is suitable for compact temperature-monitoring instruments because it combines an on-chip temperature sensor with a 12-bit, four-channel ADC and a 25 MIPS processing core. The MCU can read the internal sensor, process the result, display a status through its eight I/O pins, and operate external transducers through the other ADC channels. This integration reduces the need for a separate temperature sensor and analog converter. Accuracy still depends on the manufacturer's sensor characteristics, board heating, calibration method, and the placement of the device relative to heat sources. The 2.7 V to 3.6 V supply range should be regulated carefully because sensor and ADC performance can depend on supply and reference conditions.
おすすめ
Sensor-Conditioning and Data Acquisition
The C8051F007 supports compact sensor-conditioning and data-acquisition designs by combining four 12-bit ADC inputs, a 100 ksps conversion rate, a two-channel 12-bit DAC, and a 25 MIPS digital core. Analog sensor outputs can be sampled directly, conditioned in firmware, and compared against thresholds using the integrated comparator; the DAC can also produce excitation or test signals when the application requires them. Its eight I/O pins can handle sample commands, ready signals, data selection, and status reporting. Board-level design must include input-range protection, suitable grounding, and an analog supply strategy that prevents switching or digital activity from degrading conversion results.
おすすめ
Motor and Actuator Controller
The C8051F007 can supervise compact motor or actuator systems because its 25 MIPS 8051 core provides enough control throughput for sequencing, fault handling, and closed-loop updates, while the eight I/O pins support encoders, limit sensors, enable lines, and drive-command interfaces. The four-channel 12-bit ADC can monitor current, position, or supply feedback at up to 100 ksps, and the comparator can provide fast threshold events. The two DAC channels may generate bias or reference signals in suitable analog subsystems. Because the MCU supply is limited to 3.6 V, power-stage transistors and protection circuits are required for higher-energy loads, and switching-node layout must remain separated from sensitive analog inputs.
おすすめ
Laboratory Measurement Equipment
The C8051F007 is applicable to compact laboratory measurement equipment where an instrument needs local acquisition, stimulus generation, and control in one device. Its 12-bit four-channel ADC can sample up to four analog inputs at 100 ksps, while the dual 12-bit DAC can generate two reference or calibration outputs. The 25 MIPS processor can execute acquisition routines, averaging, filtering, and instrument-control logic, and the eight I/O pins can connect displays, buttons, status indicators, or a host interface. Because the MCU has only 2.25 KB of RAM, designers should stream or process data efficiently. Precision analog layout, reference stability, shielding, and calibration are more important for laboratory accuracy than raw conversion speed alone.
おすすめ
Programmable Analog Signal Generator
The C8051F007 can implement a small programmable analog signal generator because its two-channel 12-bit DAC provides controlled analog outputs while the 25 MIPS core manages waveform data and timing. The four-channel ADC can provide feedback or monitoring of the generated outputs, and the comparator can identify threshold crossings. Eight I/O pins are available for synchronization, mode selection, and external triggers. Practical designs must account for the 2.25 KB RAM limit, DAC output settling, output-buffer distortion, and the 2.7 V to 3.6 V analog headroom. If the required waveform precision, amplitude, or stability exceeds the on-chip DAC capabilities, an external converter or precision reference may be needed.

設計ノート
Confirm every numbered LQFP pin against the Silicon Labs C8051F0xx datasheet before routing. In particular, separate the ADC inputs, DAC outputs, comparator-related connections, oscillator pins, reset, and programming interface by following the manufacturer's recommended reference schematic. Do not infer analog or programming functions from package position alone, because the verified source set supplied a 32-pin package identity but not a reliable pin-number map.
Design the supply rail for the complete 2.7 V to 3.6 V operating range and place local decoupling close to the device's supply and ground connections. The mixed-signal ADC, DAC, comparator, and temperature sensor make supply quality relevant to measurement quality. Use a low-noise source where conversion accuracy matters, maintain a stable ground reference, and prevent digital switching currents from sharing uncontrolled return paths with analog inputs.
Keep analog traces short, shielded where appropriate, and physically separated from clocks, switching-node connections, and high-current actuator paths. The ADC can sample at up to 100 ksps, but the usable system bandwidth still depends on source impedance, acquisition settling, reference stability, and the circuit feeding each input. Avoid routing sensitive analog signals directly beneath or beside digital signals without a ground reference and appropriate protection.
Do not assume that every C8051F00x-family member is firmware- and pin-compatible with the C8051F007. The shared 8051 heritage and 32-LQFP family context do not eliminate differences in flash, RAM, ADC, DAC, oscillator, or peripheral mapping. When evaluating a replacement, review the official device datasheet, compare all 32 pins, check interrupt and register definitions, and validate the complete firmware build on the selected part.
