MPN: CY8C3446LTI-083 ✓ AktifCY8C3446LTI-083 Genel Bakış
A PSoC, or Programmable System-on-Chip, is a microcontroller architecture that integrates a CPU with configurable peripheral blocks. In the CY8C34 family, the 8051 CPU executes firmware while programmable digital blocks support timing, serial protocols, control functions, and general-purpose logic. Analog resources can be used for signal conditioning and measurement, reducing the need for separate peripheral ICs when the application can be mapped into the device's programmable fabric.
Key verified features of the CY8C3446LTI-083 include an 8-bit 8051-compatible processor, 50 MHz maximum clock operation, 64 KB flash, 8 KB SRAM, and operation from 1.71 V to 5.5 V. The family documentation also identifies 2 KB of data EEPROM, four flash protection levels, eight interrupt sources, eight priority levels, and one Peripheral Hub Unit with eight parallel access paths. These characteristics make the device suitable for designs requiring flexible peripheral allocation, embedded flash storage, and mixed control connectivity.
The CY8C34 family's configurable blocks distinguish it from a conventional fixed-peripheral microcontroller. Designers can allocate digital resources according to system timing and communication requirements instead of selecting a device solely from a fixed block map. The result is a compact system-level solution for control boards, sensor interfaces, USB-connected products, and motor-drive or motion-control applications. The 48-QFN package also supports compact PCB layouts, although exposed-pad thermal management must be considered during layout.
Typical uses include USB and serial connectivity in embedded peripherals, industrial measurement and control systems, consumer interfaces, and motor-control or motion-control platforms. The 1.71 V minimum operating voltage supports low-voltage system rails, while the 5.5 V maximum provides compatibility with conventional 5 V powered equipment. Firmware and peripheral configuration should be validated against the family's complete datasheet and the selected development kit before production release.
When designing a board around the CY8C3446LTI-083, verify the exact package pinout, exposed-pad connection, supported I/O voltage, USB implementation requirements, and programming interface in the manufacturer documentation. Use the device's low-power operating modes when appropriate, but confirm wake-up behavior and active-state current against the actual system workload. USB-connected or motor-control designs also need careful grounding, filtering, and signal-integrity planning.
This product summary consolidates verified distributor specifications, the available same-family cross-reference, and practical engineering guidance into one searchable reference. It is intended to help engineers evaluate the CY8C3446LTI-083 for embedded control, USB, serial, and motion-control designs without treating a nearby family member as an automatic substitute.

USB-Connected Embedded Peripherals
The CY8C3446LTI-083 fits USB-connected embedded peripherals because it combines a 50 MHz 8051 CPU, 64 KB flash, 8 KB SRAM, and USB plus serial connectivity in one 48-QFN device. Firmware can divide tasks among the CPU and configurable digital resources while supporting control, configuration, and data-transfer functions without relying on a separate microcontroller. The 1.71 V to 5.5 V operating range provides design flexibility across low-voltage and conventional powered systems. During implementation, verify USB signal routing, transceiver requirements, impedance, ground continuity, and host compatibility from the complete family datasheet.

Motor Drive and Motion Control
The CY8C3446LTI-083 is applicable to compact motor-drive and motion-control systems where an 8-bit control engine, 50 MHz operation, and programmable peripheral blocks are valuable. Its 8051 CPU can execute control algorithms while configurable digital functions handle timing, sequencing, and communication tasks. The 64 KB flash and 8 KB SRAM provide space for application firmware and working state, while the 1.71 V to 5.5 V range supports multiple embedded power architectures. Validate control-loop timing, PWM routing, motor-driver interface levels, thermal margins, and isolation requirements before production.

Industrial Sensor and Signal Interface
The CY8C3446LTI-083 can consolidate sensor acquisition and control in industrial interface boards because PSoC devices combine an 8051 CPU with configurable digital and analog resources. The 50 MHz processor supports protocol handling and control logic, while 64 KB flash and 8 KB SRAM accommodate configuration, diagnostics, and local processing. Operation from 1.71 V to 5.5 V allows the device to fit several sensor and industrial-control power schemes. Engineer the analog front end separately, verify usable I/O and analog limits, and confirm isolation, EMC, grounding, and sensor-signal conditioning requirements.

Low-Voltage Consumer Control Boards
The CY8C3446LTI-083 supports low-voltage consumer-control boards where compactness, programmable peripherals, and embedded flash are advantageous. Its 1.71 V minimum operating voltage suits battery-derived or reduced-voltage systems, while the 5.5 V maximum supports common powered-control environments. The 48-QFN 7 x 7 mm package minimizes PCB area, and the PSoC architecture can consolidate logic that would otherwise require multiple fixed-function ICs. Account for exposed-pad soldering, input tolerances, RF-sensitive routing, brownout behavior, and firmware update requirements during layout and validation.

Programmable Logic and Timing Subsystem
The CY8C3446LTI-083 is well suited to designs that benefit from programmable digital logic alongside a conventional CPU. Its PSoC 3 architecture lets designers use configurable blocks for timing, state machines, serial functions, and application-specific control rather than relying only on fixed peripherals. The 50 MHz CPU and 8 KB SRAM support supervisory firmware, diagnostics, and configuration, while 64 KB flash stores the active program and nonvolatile parameters. Confirm available digital block counts, routing constraints, clock-domain limits, and pin-mux options in the family datasheet before committing the design.

Tasarım Notları
Treat the 48-QFN exposed pad as a thermal and electrical land, not as an optional connection. Verify whether the family datasheet requires the pad to connect to ground or another net, then use the manufacturer-recommended footprint and solder-mask pattern. Place decoupling capacitors close to their specified power pins, preserve a continuous ground reference beneath the device where permitted, and avoid placing high-current switching paths beneath analog or USB-related routing.
Do not assume that a similar CY8C34 suffix is automatically interchangeable. The verified CY8C3446LTI-073 candidate shares the CPU, flash, SRAM, and maximum frequency, but the supplied data does not explicitly confirm temperature grade, qualification, USB implementation, pinout, or lifecycle terms. Compare the current Infineon ordering tables and complete family datasheet before substituting it into a released design.
Use the 1.71 V to 5.5 V operating range as a system constraint rather than assuming every peripheral works across the entire range. Confirm voltage-dependent frequency limits, USB operating conditions, input thresholds, and internal analog specifications in the datasheet. Provide local supply filtering close to the device, maintain a stable reference ground, and use brownout or reset behavior appropriate for the motor, USB, or industrial control load.
For USB-connected designs, route the interface as a controlled-impedance differential pair and keep return paths continuous. Avoid splitting the ground plane beneath the pair, and place required termination or protection according to the complete interface specification. For motor-control boards, keep switching-node copper and high-current returns away from the MCU, analog inputs, and communication lines. Validate layout with signal-integrity and EMC measurements on the finished board.
Uyumluluk Bilgisi
The supplied verified snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from general manufacturer policies.
