Teilenummer: CY8C3645AXE-169 ✓ AktivCY8C3645AXE-169 Übersicht
A PSoC 3, or programmable system-on-chip, is a mixed-signal microcontroller architecture that integrates a CPU, programmable analog and digital peripheral blocks, and signal-processing resources. This system-on-chip approach can reduce the number of separate components needed when a design requires sensor measurement, control logic, data processing, and digital communication. Within the component hierarchy, the CY8C3645AXE-169 belongs to the CY8C36 family of 8-bit microcontrollers and combines MCU functionality with configurable analog and digital peripherals.
The principal verified specifications are a 48 MHz clock, 32 KB flash memory organized as 32K by 8 bits, an 8051 instruction-set core, and a 0.5 V to 5.5 V supply range. These parameters position the device for compact embedded-control applications requiring moderate processing speed and integrated programmable resources. The 100-pin TQFP package provides a substantial pin count for external sensing, communication, control, and mixed-signal connections compared with smaller microcontroller packages.
The CY8C36 family architecture supports signal acquisition, signal processing, and control through configurable blocks. This enables designers to implement functions such as analog sensing, digital logic, and communications control around a common programmable platform. The 32 KB embedded flash provides on-chip program storage, while the 48 MHz operating frequency supports faster execution than basic low-speed 8-bit control devices. Exact RAM, peripheral count, GPIO count, and converter performance require confirmation from the manufacturer datasheet.
Typical uses include industrial sensing and control modules, building automation interfaces, consumer product controllers, communication equipment, and embedded systems requiring programmable analog and digital blocks. The device may also be evaluated in educational and prototype platforms because its broad peripheral integration can simplify board partitioning. Firmware compatibility and peripheral availability must be checked for each exact family member before production use.
A key design consideration is package complexity. The 100-pin TQFP footprint requires careful escape routing and adequate PCB land-pattern accuracy. Designers should also verify the selected voltage range, clock configuration, pin multiplexing, and power-supply requirements against the manufacturer datasheet rather than assuming that every CY8C36 member has identical resources. The verified distributor data identifies the CY8C3645AXE-169 as a 100-TQFP, 14 mm by 14 mm device.

Industrial Sensor and Control Module
The CY8C3645AXE-169 fits industrial sensor and control modules that benefit from programmable analog and digital functions alongside an 8-bit MCU. Its verified 48 MHz operating frequency supports responsive control logic, while 32 KB of flash provides on-chip firmware storage. The 100-pin TQFP exposes more external connection options than a small microcontroller package, although exact GPIO and converter assignments must be confirmed in the CY8C36 family datasheet. Engineers should reserve pins for the sensor interface, actuator drivers, communications, and stable power distribution. This is a useful architecture when reducing separate analog and digital ICs is important, but it requires PSoC Creator or equivalent device configuration and validation of the operating-temperature range before deployment.

Building Automation and Environmental Control
The CY8C3645AXE-169 is suitable for building-automation nodes that acquire sensor information and operate relays, indicators, or communication interfaces. Its 0.5 V to 5.5 V verified operating range allows integration with compatible low-voltage circuitry, while the programmable PSoC 3 blocks can reduce the number of discrete signal-conditioning components. The 32 KB flash capacity is suitable for compact control firmware, and the 48 MHz 8051 core provides more execution headroom than the slowest 8-bit controllers. Before design release, verify the exact pin multiplexing, analog performance, low-power behavior, and temperature limits for the selected device. Firmware must also include startup validation and fault handling for connected sensors and actuators.
Empfohlen
Communication Equipment Interface
The CY8C3645AXE-169 can serve as the supervisory controller in communication equipment where a compact 8-bit MCU must handle configuration, status, and control functions. The verified 48 MHz operating frequency supports responsive protocol handling and supervisory tasks, while 32 KB of flash stores firmware without requiring an external program-memory device. Its 100-pin TQFP footprint offers ample physical pins for serial links, indicators, resets, and interface control. Designers should isolate high-speed or high-voltage communication circuitry from the MCU and use the manufacturer's recommended clock and power arrangements. Confirm the exact available communications peripherals, pin assignments, and electrical limits before selecting it for a new protocol design.

Consumer Product Control
The CY8C3645AXE-169 can be evaluated for compact consumer-product controllers that combine user inputs, analog sensing, timing, and digital control. The PSoC 3 architecture integrates configurable resources with the 8051 MCU, reducing the need for separate logic devices in cost-sensitive designs. A 48 MHz core supports responsive control tasks, and 32 KB flash is useful for storing application firmware and configuration data. The 100-pin TQFP requires more PCB area than a small-lead package, so its benefit depends on functional integration and assembly capability. Validate low-power requirements, startup behavior, peripheral accuracy, and production availability before committing to a high-volume consumer design.

Data Acquisition and Signal Processing
The CY8C3645AXE-169 fits data-acquisition designs that require acquisition, digital processing, and control in one device. Its PSoC 3 architecture combines an 8051 microcontroller with programmable analog and digital blocks, allowing signal-chain functions to be configured more flexibly than a fixed-function peripheral implementation. The 48 MHz processing frequency supports real-time control, and the 32 KB flash provides dedicated program storage. Because the verified source does not expose converter resolution, sample rate, or specific ADC specifications, engineers must confirm those values in the family datasheet. Input protection, grounding, filtering, and reference-voltage design should follow the manufacturer recommendations to preserve measurement accuracy.
Empfohlen
Educational and Prototype Platform
The CY8C3645AXE-169 is suitable for MCU education, embedded-control training, and prototype development because it integrates an 8051 core with programmable analog and digital resources. The 48 MHz operating frequency provides a practical platform for interrupts, timers, communication, signal acquisition, and mixed-signal experiments, while 32 KB flash is adequate for many instructional firmware examples. The 100-pin TQFP footprint makes it easy to access many signals on a development board but requires careful fanout and soldering. Start with the exact pin assignment and configuration documentation, then verify peripheral behavior using a controlled prototype. Production suitability should be reassessed against lifecycle, temperature, and qualification requirements.

Wichtigste Unterscheidungsmerkmale
- Verified 32 KB flash with 48 MHz operation (vs. CY8C3644AXE-169)
- Broad 0.5 V to 5.5 V operating range (vs. CY8C3646AXE-169)
- 100-pin TQFP integration in 14 mm by 14 mm footprint (vs. CY8C3647AXE-169)
Designhinweise
The CY8C3645AXE-169 uses a 100-pin TQFP land pattern, so PCB design must follow the exact package drawing and pin table rather than a generic 100-pin symbol. Confirm pin-1 orientation, exposed versus non-exposed thermal-pad details, and all power and ground assignments in the manufacturer package information. A symbol-and-footprint cross-check against the selected variant should be completed before fabrication.
The verified supply range is 0.5 V to 5.5 V, but that range does not by itself define a usable system rail. Verify the device's core, I/O, analog, and power-sequencing requirements in the CY8C36 family datasheet. Provide local bypass capacitance, maintain the recommended return path, and separate noisy analog and digital returns where the application permits to reduce supply coupling and measurement error.
Route sensitive analog inputs away from digital clocks, fast-edge signals, switching supplies, and high-current output paths. Keep the analog ground reference short and maintain continuous return paths beneath the device where the manufacturer layout guidance permits. Because the verified data does not specify ADC resolution, converter topology, or recommended external components, those values must be obtained from the exact family datasheet before finalizing the front end.
Do not assume that adjacent CY8C36 MPNs are interchangeable merely because they use the same package. Check flash capacity, RAM, clock limits, GPIO mappings, analog resources, temperature grade, qualification, and active lifecycle status. A footprint-compatible replacement can still require firmware changes if peripheral assignments or device identifiers differ, so complete schematic, timing, and firmware regression checks before substitution.
Compliance-Informationen
The supplied verified results confirm the part identity, electrical headline specifications, package, price, and availability, but they do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance claim has been inferred.
