CY8C3445PVI-094 - 50MHz 8051 PSoC 3 MCU 32KB Flash | Infineon
料号： CY8C3445PVI-094 ✓ 量产中CY8C3445PVI-094 概述
A PSoC, or programmable system-on-chip, is a microcontroller architecture that integrates a CPU, programmable digital blocks, configurable analog peripherals, memory, and routing resources on one device. PSoC 3 belongs to the broader embedded-microcontroller and programmable-system-on-chip hierarchy. This integration allows engineers to implement application-specific functions in hardware-like configurable blocks rather than relying only on fixed peripherals, helping reduce external component count in compact control designs.
The CY8C3445PVI-094 provides 32 kByte of Flash, 4 kByte of SRAM, a 50 MHz maximum 8051-core clock, a 48-SSOP package, and an operating voltage range of 1.71 V to 5.5 V. The family also supports configurable analog and digital peripherals, flexible signal routing, a DMA controller, and interrupt-driven embedded processing. These characteristics make the device suitable for industrial instrumentation, sensor interfaces, compact control systems, communications modules, and low-power embedded products.
The 8051 core provides a familiar architecture for cost-sensitive embedded designs, while PSoC 3 peripherals extend the design capability beyond a conventional fixed-function MCU. The manufacturer describes the device as supporting operation up to 50 MHz and combining programmable analog and digital resources with memory and interrupt handling. The 48-SSOP package is intended for through-hole-style leaded PCB assembly rather than a compact land-grid-array footprint.
Typical applications include sensor signal conditioning, data acquisition, industrial monitoring, low-speed communication, embedded measurement, and custom control products. Engineers should verify the exact peripheral configuration, clock requirements, pin multiplexing, and programming setup in the manufacturer datasheet before finalizing a board design.
A key design consideration is the 48-SSOP footprint and its relatively long leads compared with modern fine-pitch packages. Confirm that the PCB land pattern, solder assembly process, and available board area accommodate the device. For firmware development, use the PSoC Creator tooling and programming interface appropriate for the selected device family, and verify the exact pin assignments and peripheral configuration in the datasheet.
This product page summarizes the key electrical, memory, package, and application characteristics of CY8C3445PVI-094 and provides practical guidance for evaluating it in embedded PSoC 3 designs. It also distinguishes verified manufacturer information from technical details that must be confirmed against the complete datasheet before layout or production release.

典型应用
CY8C3445PVI-094 适用于 6 应用s: Industrial Sensor Acquisition, Programmable Signal Conditioning, Low-Power Embedded Control, Data Acquisition and Logging, Communication Interface Controller, Compact Measurement Instrument.
Industrial Sensor Acquisition
The CY8C3445PVI-094 fits industrial sensor acquisition systems that require configurable signal conditioning, rapid interrupt handling, and local control. Its 50 MHz 8051 core can supervise acquisition sequences, while the PSoC 3 configurable analog and digital resources allow sensor interfaces to be tailored without relying on a large collection of fixed peripherals. The 1.71 V to 5.5 V operating range supports low-voltage sensing architectures. Before implementation, verify the required ADC characteristics, input limits, sampling behavior, and exact peripheral assignments in the manufacturer datasheet.
推荐
Programmable Signal Conditioning
The PSoC 3 architecture makes CY8C3445PVI-094 appropriate for programmable signal-conditioning products where analog and digital functions must be combined in one controller. Its 20 Universal Digital Blocks, configurable analog resources, and flexible routing can implement application-specific filtering, thresholding, timing, or interface logic. The 32 kByte Flash supports moderate application firmware, while 4 kByte SRAM supports working buffers. Confirm resource sharing, timing, and analog performance for the intended signal chain against the manufacturer documentation.
推荐
Low-Power Embedded Control
CY8C3445PVI-094 is appropriate for compact embedded controllers that combine low-voltage operation with programmable peripherals. Its operation from 1.71 V to 5.5 V allows designers to work within energy-conscious sensor, actuator, and portable-equipment power budgets. The 50 MHz 8051 core provides processing headroom, while the PSoC 3 configurable blocks can offload functions that would otherwise require separate logic. Actual sleep behavior, wake sources, and active-current performance depend on the device configuration, so validate them in the datasheet and firmware.
推荐
Data Acquisition and Logging
The CY8C3445PVI-094 can serve as the central controller in a compact acquisition and logging system, combining an 8051 processor with programmable analog and digital resources. Its 50 MHz clock supports interrupt-driven sampling, protocol handling, and local data management, while 32 kByte Flash and 4 kByte SRAM accommodate embedded control code and working data. The device's industrial temperature grade supports industrial environments when the complete system is thermally qualified. Determine external memory, interface, and storage requirements before finalizing the architecture.
推荐
Communication Interface Controller
CY8C3445PVI-094 can support communication-interface roles that require configurable logic, interrupts, and manageable firmware complexity. The two data pointers, 27 interrupt sources, eight priority levels, and eight PHub access paths help coordinate simultaneous embedded activities, while the 50 MHz core provides timing headroom for protocol tasks. The device does not specify a dedicated communication transceiver on the verified product page, so the external interface circuitry and signal levels must be designed separately. Validate pin multiplexing and protocol timing in the datasheet.
推荐
Compact Measurement Instrument
The CY8C3445PVI-094 is well suited to compact measurement instruments that combine configurable signal processing with embedded display, control, and communications. Its 48-SSOP package provides a leaded assembly option useful for industrial boards requiring visual inspection or manual assembly, while the PSoC 3 resources can consolidate analog and digital functions. The 32 kByte Flash stores application firmware and 4 kByte SRAM supports active measurements. Check display and interface timing, calibration requirements, and enclosure thermal conditions before production use.

关键差异点
- Established 50 MHz PSoC 3 configuration （对比 CY8C3245PVI-134)
- Broad low-voltage operating range （对比 CY8C3245PVI-134)
- Configurable PSoC peripheral architecture （对比 CY8C3245PVI-134)
设计说明
Use the 48-SSOP land pattern and pin numbering defined by the manufacturer package drawing. Confirm body width, lead span, row spacing, and pin-1 orientation before PCB release. Because this is a 48-pin SSOP rather than a compact no-lead package, leave adequate routing clearance and inspect joints for solder bridging during assembly.
Design the supply network for the device's 1.71 V to 5.5 V operating range and validate every external peripheral's voltage limits. Place the required bypass capacitors adjacent to the relevant supply and ground pins, use a low-impedance ground plane, and separate noisy switching-current paths from sensitive analog routing. Check power sequencing and I/O limits in the manufacturer datasheet.
Program the PSoC routing, analog blocks, and digital peripherals only after defining the required signal path and timing. Review pin alternate functions and peripheral-sharing constraints in the device documentation, then reserve clean analog routing away from high-current switching nodes. Validate gain, bandwidth, and timing with the intended sensor or source because package placement and grounding materially affect analog performance.
Do not substitute a device merely because it is also labeled 48-SSOP or 32 kByte Flash. Verify the complete pin map, supply range, core behavior, memory organization, peripheral set, package drawing, and programming configuration. CY8C3245PVI-134 appears in comparison data, but it must not be treated as a drop-in replacement without a manufacturer-supported equivalence review and firmware migration check.
合规信息
The verified product information identifies an industrial-grade PSoC 3 MCU but does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Confirm these declarations on the manufacturer product page or in the current manufacturer compliance documentation before procurement.
