Product details
Overview
CY8C3245PVI-150T from Infineon Technologies (acquired Cypress Semiconductor) is a PSoC® 3 programmable system-on-chip integrating an 8051 CPU core, configurable analog and digital peripherals, 64 KB flash, 8 KB RAM, and CapSense® support. It operates from 1.71–5.5 V at up to 50 MHz, features 24-channel DMA, USB 2.0 Full-Speed interface, and supports 62-capacitive-touch-sensor applications in industrial HMI systems.
For engineers reviewing the CY8C3245PVI-150T datasheet, CY8C3245PVI-150T pinout, CY8C3245PVI-150T application, or CY8C3245PVI-150T equivalent, key selection criteria include USB 2.0 FS compliance, Delta-Sigma ADC performance (66 dB SINAD, ±1 LSB INL), I/O routing flexibility, and integrated boost regulator supporting 0.5 V input operation.
Technical Context
The device implements a single-cycle 8051 CPU with nested vector interrupt controller and 24-channel PHUB-based DMA, enabling zero-CPU-overhead peripheral data transfers. Its clock tree integrates a 3–24 MHz internal main oscillator (IMO) with ±2% accuracy at 3 MHz, a 50 MHz PLL, and a 1 kHz/33 kHz low-power ILO for RTC and wake-up timing.
Analog subsystem includes an 8–12-bit Delta-Sigma ADC (66 dB SINAD, <±1 LSB INL), dual comparators, 8-bit DAC (1 Msps VDAC / 8 Msps IDAC), and 1.024 V ±1% reference. Digital resources comprise four 16-bit TCPWM blocks, one hardware I²C (1 Mbps), full-speed USB 2.0 PHY, and 24 Universal Digital Blocks (UDBs) for custom logic synthesis.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C3246FVI-150T | 68-QFN package (vs. 48-SSOP); adds 2 extra GPIO and 1 additional SIO pin; identical core/peripheral specs. | Better thermal dissipation and higher I/O count; suited for space-constrained designs requiring >29 pins. | Select when board layout allows QFN and additional I/O or thermal margin is needed. |
| CY8C3866AXI-065 | Higher flash (128 KB) and RAM (16 KB); adds CAN 2.0B controller; same 8051 core and CapSense® engine. | Targeted at automotive body electronics requiring CAN bus integration and larger firmware footprint. | Choose only if CAN interface and extended memory are mandatory; not drop-in compatible due to pinout and voltage domain differences. |

FAQ
Does CY8C3245PVI-150T support USB device enumeration without external crystal?
Yes. The device includes a certified USB 2.0 Full-Speed PHY (TID#40770053) that operates using its internal 48 MHz IMO clock, eliminating need for external 48 MHz crystal. Internal clock meets USB timing jitter requirements per specification.
What is the maximum number of CapSense® sensors supported in hardware?
The CY8C3245PVI-150T supports up to 62 capacitive sensing channels in hardware-either self-capacitance (62) or mutual-capacitance (31 pairs)-using dedicated scan engine with automatic baseline tracking and noise rejection algorithms.
Can the boost regulator power external circuitry?
Yes. The VBOOST output pin delivers regulated voltage (programmable 1.8–5.0 V) with up to 100 mA typical current. It can power external LCD bias circuits, op-amps, or sensors-subject to total power budget and thermal limits specified in datasheet Section 11.3.
Is SWD debugging supported with full trace capability?
