CY8C3245AXA-158 - 50MHz 32KB Flash MCU | Infineon
부품 번호: CY8C3245AXA-158 ✓ 활성CY8C3245AXA-158 개요
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, and peripherals into one device. The 8051 is a widely recognized 8-bit microcontroller architecture, while PSoC 3 combines that processing core with programmable digital and analog resources. In the broader semiconductor hierarchy, this device belongs to the microcontroller class and the power-management ecosystem requires its supply rail to remain within the specified 1.71 V to 5.5 V range.
The principal headline specifications are a 50 MHz operating frequency, 32 KB of flash memory, and a 1.71 V to 5.5 V supply range. Related family information identifies 4 KB of SRAM and 62 GPIOs, while the available technical summary describes a single-core architecture with dual data pointers, four flash protection levels, 1 KB of data EEPROM, 8 KB of ECC flash, and an interrupt system with 27 sources and eight priority levels.
The 8051 core provides deterministic 8-bit control behavior, while the PSoC peripheral structure allows designers to consolidate functions that would otherwise require separate discrete devices. The 100-lead TQFP package provides a high pin count relative to smaller microcontroller packages, making it suitable for systems that need more externally accessible connections. Its 14 mm by 14 mm body is larger than compact QFN packages but exposes more I/O and supports conventional board-level manufacturing and prototyping.
Typical applications include industrial control panels, sensor-conditioning equipment, building automation controllers, compact power-conversion controllers, communication modules, and general-purpose embedded products. The 50 MHz clock provides greater instruction throughput than slower 8051-class controllers, while 32 KB flash accommodates firmware, configuration data, and boot logic. For designs requiring extensive serial connectivity or a host processor interface, an external transceiver or companion controller can be added around this MCU.
Designers should preserve the 1.71 V minimum and 5.5 V maximum supply limits, provide suitable decoupling close to the device, and confirm the exact 100-pin signal assignments against the manufacturer datasheet before layout release. Because the package exposes many GPIO and peripheral functions, careful allocation can prevent conflicts between communication, timing, debug, and application-specific functions.
This page consolidates verified distributor specifications, current pricing information, same-family replacement guidance, and practical selection considerations. It also distinguishes a genuinely pin-compatible option from generic functional similarity, helping engineers identify when a PCB can be reused without assuming that every related microcontroller is an exact drop-in replacement.

일반적인 애플리케이션
CY8C3245AXA-158 적합 용도: 6 애플리케이션s: Industrial Control Panel, Building Automation Controller, Sensor Conditioning Equipment, Compact Power Conversion Controller, Communication Module Controller, General Embedded Product Controller.
Industrial Control Panel
The CY8C3245AXA-158 fits an industrial control panel that coordinates buttons, indicators, sensors, and actuator commands. Its 50 MHz 8051 core provides higher execution throughput than basic low-speed 8-bit controllers, while 32 KB flash stores panel firmware and 4 KB SRAM handles working state. The 62-GPIO family configuration allows numerous peripheral assignments, and the 100-lead TQFP package exposes those connections conveniently. Engineers should map functions against the exact pin table, isolate external interfaces, and verify the required temperature and qualification grade before deployment.
Building Automation Controller
For building automation, the CY8C3245AXA-158 can supervise lighting, temperature sensing, occupancy inputs, and controlled relays or actuators. The PSoC 3 device combines a 50 MHz 8051 processing core with programmable digital resources, reducing the need for separate logic where the verified family functions satisfy the design. Its 32 KB flash is useful for schedules and configuration, while the 1.71 V to 5.5 V operating range supports compatible embedded rails. The final design must use the exact manufacturer GPIO mapping and add suitable isolation or driver circuits for mains-connected loads.
Sensor Conditioning Equipment
The CY8C3245AXA-158 is suitable as the controller in a compact sensor-conditioning instrument that samples inputs, applies calibration, and presents processed measurements. A 50 MHz 8051 core provides useful timing headroom for filtering and communication routines, and the related family offers 62 GPIOs for digital sensors, status indicators, and external interfaces. The 32 KB flash can hold fixed-point algorithms and calibration tables, while 4 KB SRAM supports temporary working values. Signal-integrity and sensor-accuracy claims still depend on the external analog front end and must not be attributed solely to the MCU.
Compact Power Conversion Controller
The CY8C3245AXA-158 can implement supervisory and digital control functions in a compact power-conversion module. Its 50 MHz 8-bit core can service timing tasks, fault flags, and communication while the PSoC peripheral resources support programmable signal functions. Operating from a rail within 1.71 V to 5.5 V simplifies integration with compatible embedded power systems. Because this MCU is not a dedicated power-conversion IC, it should not directly replace a specialized controller; use it for supervisory logic and add dedicated gate-drive, voltage-sense, and protection circuitry.
Communication Module Controller
The CY8C3245AXA-158 works well as the host-side controller in a wired or wireless communication module. Its 32 KB flash can store protocol firmware and configuration, while the 50 MHz core provides processing capacity for framing, buffering, and status management. The 62-GPIO family count permits connection to a serial transceiver, indicators, and configuration controls, and the TQFP-100 package offers broad connectivity. Protocol timing and electrical isolation must be validated at the system level; the MCU specifications alone do not define RF performance, baud rate, or bus compliance.
General Embedded Product Controller
The CY8C3245AXA-158 is appropriate for a general embedded product combining local control, memory, and multiple I/O functions. The single-core 8051 processor runs at 50 MHz and is supported by 32 KB flash, 4 KB SRAM, 1 KB data EEPROM, and 8 KB ECC flash in the related family information. Its interrupt system provides 27 sources and eight priority levels, which is useful when several time-sensitive inputs must coexist. Product developers should reserve pins for programming, debug, reset, and clock functions before assigning the remaining GPIOs to the application.

설계 노트
Design the supply rail for the verified 1.71 V to 5.5 V operating range and account for startup, transient, and noise margins around that interval. Place the required bypass capacitors close to the device power pins, keep return-current paths short, and verify the selected regulator against the MCU's peak current rather than average operating consumption. A 100-lead TQFP also provides more power and ground connections than a small package, so use the manufacturer pin table when planning the power grid.
Treat the 100-pin TQFP as a pin-constrained design rather than a generic 8-bit controller. Assign programming, debug, reset, clock, communications, and critical timers before assigning general GPIOs. Follow the manufacturer package dimensions and land pattern, maintain the prescribed pad geometry, and route high-frequency or sensitive signals away from switching nodes and power inductors. Because the verified sources do not provide all alternate-function assignments, validate every multiplexed connection against the datasheet.
Do not assume that all PSoC 3 devices with similar order codes are automatically interchangeable. The verified search data establishes the 50 MHz core, 32 KB flash, 4 KB SRAM, 62-GPIO family configuration, and TQFP-100 format for the AXI reference, but suffix changes may alter temperature class, qualification, or ordering options. For a migration, compare the ordering-information tables, absolute maximum ratings, GPIO multiplexing, and package drawings before releasing a PCB revision.
Use the 50 MHz capability as a complete design constraint rather than an isolated headline specification. Account for clock tolerance, peripheral timing, interrupt latency, bus contention, and external component settling time. If the MCU interfaces with sensors, transceivers, or power converters, define input thresholds and protection in the application circuit. The MCU does not provide analog accuracy by itself; signal-chain noise and error must be evaluated with the external front end and its grounding arrangement.
규정 준수 정보
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for the exact AXA ordering code. These fields remain unknown rather than being inferred from family or distributor membership.
