CY8C3446PVI-102 - 50MHz 8051 PSoC 3 MCU | Infineon
MPN: CY8C3446PVI-102 ✓ فعالCY8C3446PVI-102 جائزہ
A PSoC, or programmable system-on-chip, combines a microcontroller core with configurable analog and digital peripheral blocks on one integrated circuit. This product belongs to the CY8C34xx PSoC 3 family, whose 8051 core is supplemented by Universal Digital Blocks, a configurable ADC, communication peripherals, timers, and programmable interconnect. The result is a platform that can consolidate functions that would otherwise require a separate microcontroller and several discrete peripheral devices.
The verified device data identifies 24 Universal Digital Blocks, two data pointers, 27 interrupt sources with eight priority levels, one Peripheral Hub Unit with eight parallel access paths, 64 KB of program Flash, and 8 KB of SRAM. It also includes a 2 KB data EEPROM and four Flash protection levels according to the Keil device record. These resources support structured firmware, concurrent control tasks, protocol handling, and protection of firmware intellectual property.
Operation up to 50 MHz provides headroom for responsive control loops and mixed peripheral workloads. The configurable peripheral architecture allows designers to implement timers, serial interfaces, signal processing, and communication functions in hardware instead of relying entirely on CPU software. Because the supplied records identify CAN and LIN networking, the device is positioned for both higher-speed CAN networks and lower-cost LIN subnets commonly found in vehicle and industrial control networks.
Typical applications include CAN-connected industrial controllers, LIN peripheral modules, automotive body electronics, motor and valve control, compact sensor hubs, and low-cost appliances. The 48-SSOP package supports compact through-hole PCB layouts, although pin density and thermal performance should be considered carefully in designs operating at elevated ambient temperatures.
When designing around the CY8C3446PVI-102, confirm the device's complete pinout, exposed programming and power connections, peripheral routing options, and electrical limits against the manufacturer datasheet. The verified distributor listings do not provide a complete pin table, so engineers should not infer missing pin functions from the package outline.
This page combines verified distributor and device-profile data with practical application guidance, comparison parameters, and engineering caveats. It is intended to support component identification and initial design planning while clearly separating confirmed values from parameters that require manufacturer-datasheet review.

عام استعمالات
CY8C3446PVI-102 کے لیے موزوں ہے 6 ایپلیکیشنs: CAN-Connected Industrial Control, LIN Automotive Peripheral Node, Motor and Valve Control, Compact Sensor Hub, Secure Connected Appliance, Data Acquisition and Signal Conditioning.
CAN-Connected Industrial Control
The CY8C3446PVI-102 fits CAN-connected industrial controllers because its 8051 core operates up to 50 MHz and its 64 KB Flash and 8 KB SRAM provide room for protocols, control logic, and diagnostics. The confirmed CAN interface can handle network communication while 24 Universal Digital Blocks support timers, serial functions, and other configurable real-time tasks. Place the MCU beside a suitable CAN transceiver and route communications away from sensitive analog inputs. Review clock tolerance, bus timing, transceiver standby behavior, and firmware-based fault handling before deployment; the verified data does not provide specific CAN bit-rate or timing figures.
تجویز کردہ
LIN Automotive Peripheral Node
The CY8C3446PVI-102 is appropriate for a LIN peripheral node because the verified device profile explicitly identifies LIN networking alongside CAN. Its 50 MHz maximum clock can support message handling, diagnostic routines, and local control functions, while 8 KB of SRAM provides working memory for a stack and data buffers. A LIN transceiver, connector, and correctly configured baud-rate timing remain external to the microcontroller. Validate wake-up, sleep, bus fault recovery, and LIN frame timing against the final hardware configuration rather than relying only on generic MCU specifications.
تجویز کردہ
Motor and Valve Control
The CY8C3446PVI-102 can serve as the digital controller for a motor or valve subsystem because its 8051 processor reaches 50 MHz and its 24 Universal Digital Blocks provide configurable timing and signal-processing resources. The 64 KB Flash accommodates a complete control application, while the 8 KB SRAM supports state variables and communication buffers. The MCU should not directly drive power devices; use gate drivers, protection circuitry, and appropriate sensing isolation. Validate timing margins, fault shutoff behavior, and analog input scaling because no motor-output ratings or ADC resolution were included in the verified data.
تجویز کردہ
Compact Sensor Hub
The CY8C3446PVI-102 suits a compact sensor hub where limited board space must coexist with memory, timing, and mixed-signal resources. Its confirmed 1.71 V to 5.5 V range supports low-voltage embedded rails, while the configurable ADC and 24 Universal Digital Blocks can be allocated to acquisition, filtering, and control functions. Eight kilobytes of SRAM and 64 KB of Flash provide more usable capacity than a basic 8-bit controller. Keep analog and digital return paths separated, provide local bypass capacitance according to the manufacturer guidance, and confirm ADC accuracy and available I/O before assigning sensors.
تجویز کردہ
Secure Connected Appliance
The CY8C3446PVI-102 is suitable for a connected appliance controller that needs deterministic embedded control and modest networking support. Four Flash protection levels can help organize access to firmware, and the 2 KB data EEPROM provides nonvolatile configuration storage according to the verified device profile. The 50 MHz core manages control loops and communication, while CAN or LIN can connect the appliance to a higher-level controller. Security provisioning, bootloader recovery, brownout behavior, and production programming should be planned early because detailed flash endurance, write timing, and cryptographic-hardware specifications were not supplied.
تجویز کردہ
Data Acquisition and Signal Conditioning
The CY8C3446PVI-102 can support compact data-acquisition modules by combining an 8051 core operating up to 50 MHz with a configurable ADC and 24 Universal Digital Blocks. Those configurable blocks can implement sampling, timing, counters, and digital filtering while the processor handles buffering and host communication. The confirmed 64 KB Flash and 8 KB SRAM provide sufficient space for moderate acquisition workloads. Use short analog traces, solid grounding, and careful separation from switching circuitry. ADC resolution, acquisition time, input impedance, and calibrated accuracy must be obtained from the manufacturer datasheet before selecting the part for precision measurement.

ڈیزائن نوٹس
Place all decoupling capacitors directly beside the device power pins and keep their ground returns short. The verified 1.71 V to 5.5 V supply range does not establish the required capacitor values or permissible voltage derating, so select those components from the manufacturer power-supply guidance. Provide a clean return plane for the 8051 core and configurable analog blocks, while separating clocks, communication routing, and switching-node currents to reduce coupling into sensor and timing circuits.
Do not treat a shared PVI package designation as proof that every family member has identical peripheral routing, clock limits, or temperature grade. The alternatives listed in this page are same-family candidates, not blanket approval for redesign. Compare the exact orderable MPN, pin names, programming interfaces, maximum clock, voltage limits, qualification, and package dimensions in the current manufacturer data sheet before replacing CY8C3446PVI-102.
Route the 50 MHz clock and high-speed digital interfaces away from the configurable ADC inputs, and return unused adjacent signal inputs to a defined state as directed by the manufacturer. Because the verified excerpts do not contain the complete pinout or recommended layout, engineers must consult the package drawing and reference design before final routing. This is especially important for SSOP layouts, where fine lead pitch limits rework and makes early pin-assignment review valuable.
Validate startup, brownout recovery, and power-supply tolerance across the full 1.71 V to 5.5 V operating range. The MCU's 64 KB Flash and extensive configurable peripherals can create changing current demand as clocks, communications, and analog blocks are enabled. Measure worst-case supply droop at the pins with representative firmware rather than estimating from nominal average current, and include local bulk capacitance only where supported by the manufacturer guidance.
