Product details
Overview
CY8C3245PVI-134T from Infineon Technologies (acquired Cypress Semiconductor) is a programmable 8-bit PSoC® 3 system-on-chip integrating an 8051 CPU core, configurable analog and digital peripherals, 64 KB flash, 8 KB RAM, and up to 29 GPIOs in a 48-pin SSOP package. It supports CapSense® touch sensing, Delta-Sigma ADC (12-bit), 8-bit DAC, USB 2.0 FS, I²C, and PWM-enabling single-chip replacement of microcontroller + analog front-end + interface ICs in industrial HMI and sensor node designs.
For engineers reviewing the CY8C3245PVI-134T datasheet, CY8C3245PVI-134T pinout, CY8C3245PVI-134T application, or CY8C3245PVI-134T equivalent, key selection criteria include its 50 MHz 8051 performance, 1.71–5.5 V operating range, 200 nA hibernate mode with RAM retention, USBIO-capable pins, and UDB-based reconfigurable logic for custom digital functions without external glue logic.
Technical Context
The device implements a single-cycle 8051 CPU core with 32 interrupt inputs and 24-channel DMA, enabling real-time peripheral-to-memory transfers without CPU overhead. Its digital subsystem centers on 24 Universal Digital Blocks (UDBs), each combining PAL/PLD logic and a state machine engine to synthesize UART, SPI, LIN, PRS, CRC, quadrature decoders, or custom PWM timers.
Analog functionality includes a 12-bit Delta-Sigma ADC (±1 LSB INL, 66 dB SINAD), dual voltage comparators, 1.024 V ±1% internal reference, and CapSense® support for up to 62 sensors-all routed flexibly across GPIOs via programmable analog interconnect. Clocking combines a 3–24 MHz IMO (±2% at 3 MHz), 50 MHz PLL, and 32.768 kHz RTC crystal support.

IC Role / Device Role / Timing Role: High-precision analog acquisition engine (Delta-Sigma ADC with programmable gain), real-time waveform capture (DMA to RAM), and firmware-upgradable communication stack. Use Value: On-chip 64 KB flash stores dual-application images (metering + diagnostics); ECC protection prevents field corruption during power interruption. | Use Scenario: Modular ATE fixture controlling solenoid actuators, reading thermocouple inputs, and reporting pass/fail status via USB to host PC. IC Role / Device Role / Timing Role: Deterministic real-time sequencer (UDB-based PWM timing), isolated analog input conditioning, and USB bulk transfer handler for test logs. Use Value: 24-channel DMA moves sensor data directly to USB buffers-eliminating CPU polling and guaranteeing ≤100 µs response to trigger events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C3245FVI-134T | Same die, QFN-48 package (0.5 mm pitch); no SSOP footprint compatibility. | Preferred for space-constrained PCBs requiring thermal pad grounding and lower profile. | Select when board layout prioritizes miniaturization and thermal dissipation over through-hole prototyping ease. |
| CY8C3246PVI-134T | Same SSOP-48 package but with 100-TQFP-compatible pinout mapping; adds 4 extra GPIOs (33 total) and 2 KB more flash. | Suitable for designs needing expanded I/O without changing PCB layer stackup. | Choose when future-proofing I/O count or adding firmware features without redesigning the board. |
Compared with CY8C3245PVI-134T, the FVI variant trades package compatibility for thermal performance and density, while the PVI-134T variant offers identical footprint with extended I/O-making the original optimal for cost-sensitive, volume-manufactured SSOP-based designs where pin count and legacy layout reuse are critical.

FAQ
What development tools are required to program and debug CY8C3245PVI-134T?
The device is fully supported by the free PSoC Creator™ IDE, which includes schematic-based hardware design, component library integration, and Keil 8051 compiler. Programming and debugging require MiniProg3 (JTAG/SWD) or KitProg (on CY8CKIT-001). USB-based bootloader programming is also supported via I²C, SPI, UART, or native USB HID/CDC interfaces without external hardware.
Does CY8C3245PVI-134T support true hardware USB enumeration without host-side driver installation?
Yes-it implements a full-speed USB 2.0 device controller certified to TID#40770053. When configured as HID or CDC class, it enumerates natively on Windows, macOS, and Linux without custom drivers. The internal USB PHY, terminators, and descriptor engine operate independently of CPU load, ensuring reliable plug-and-play connectivity.
Can the Delta-Sigma ADC achieve 12-bit effective resolution in noisy industrial environments?
Yes-the ADC achieves 12-bit ENOB under specified conditions: 1.024 V internal reference (±1%), programmable gain amplifier (PGA), and digital filtering via firmware-configurable oversampling. Layout guidelines (AN57821) mandate separate analog/digital grounds and guard traces; with proper PCB design, INL remains <±1 LSB and SINAD >66 dB even with 50/60 Hz EMI.
Is the 200 nA hibernate mode achievable with all peripherals disabled and external wake sources active?
Yes-hibernate mode retains SRAM contents while disabling CPU, flash, USB, and all clocks except the 1 kHz ILO. Wake events can be triggered by GPIO interrupt, RTC alarm, or comparator output. Verified current draw is 200 nA typical at 25°C with VDD = 3.3 V, measured per JEDEC JESD78 standards using calibrated picoammeter and shielded test fixtures.
