Product details
Overview
CY8C3244PVI-133T from Infineon Technologies (formerly Cypress Semiconductor) is a programmable 8-bit PSoC® 3 system-on-chip integrating an enhanced 8051 CPU core, configurable analog and digital peripherals, 64 KB flash, 8 KB RAM, and CapSense® capacitive sensing capability. It operates from 1.71–5.5 V, supports up to 50 MHz clocking via internal PLL, and delivers ultra-low-power operation with 200 nA hibernate mode (RAM retention). It is used in embedded human-interface systems requiring mixed-signal integration and firmware-defined functionality.
For engineers reviewing the CY8C3244PVI-133T datasheet, CY8C3244PVI-133T pinout, CY8C3244PVI-133T application, or CY8C3244PVI-133T equivalent, key selection criteria include its 48-pin SSOP package, 29 GPIOs with analog routing flexibility, integrated Delta-Sigma ADC (12-bit, <±1 LSB INL), USB 2.0 FS interface, and UDB-based reconfigurable digital logic for custom peripheral synthesis.
Technical Context
The CY8C3244PVI-133T implements a single-cycle 8051 CPU running at up to 50 MHz, backed by a 24-channel DMA controller and nested vector interrupt controller for sub-2-cycle latency. Its digital subsystem centers on 16 Universal Digital Blocks (UDBs), enabling user-defined logic such as UART, SPI, PRS, CRC, quadrature decoders, and PWM generators - all routable to any GPIO.
Analog resources include an 8–12-bit Delta-Sigma ADC (66 dB SINAD, ±100 µV offset), dual comparators, 8-bit DAC (1 Msps VDAC / 8 Msps IDAC), and dedicated CapSense® blocks supporting up to 62 sensors. All analog signals route through a shared analog interconnect, with 1.024 V ±1% internal reference and independent I/O voltage domains (VDDIO0–VDDIO3).

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C3246PVI-132 | Same 48-SSOP package, but includes USB 2.0 HS (480 Mbps) instead of FS; adds 2 KB more EEPROM. | Better suited for high-bandwidth data streaming (e.g., audio capture), not required for basic HID or CDC use cases. | Select only if USB HS throughput or extended nonvolatile data storage is mandatory. |
| CY8C4014LQI-422 | PSoC 4 (ARM Cortex-M0+) variant in 48-QFN; lower power (150 nA hibernate), no USB PHY, reduced analog precision (10-bit SAR ADC). | Targeted at cost-sensitive, low-complexity applications where ARM toolchain preference outweighs need for CapSense® tuning or Delta-Sigma ADC linearity. | Choose when migrating to ARM ecosystem or when USB and high-precision analog are unnecessary. |
Compared with CY8C3244PVI-133T, CY8C3246PVI-132 adds USB HS bandwidth at identical package and pinout, while CY8C4014LQI-422 trades analog fidelity and USB integration for ARM compatibility and deeper sleep - making the CY8C3244PVI-133T optimal for legacy 8051-based, CapSense®-centric designs demanding Delta-Sigma ADC accuracy.

FAQ
Does CY8C3244PVI-133T support USB device enumeration without external components?
Yes. The part integrates a full-speed USB 2.0 physical layer (PHY) and USB controller with on-die termination resistors and internal pull-up/pull-down logic. No external transceiver, resistors, or crystal is required for standard HID or CDC class operation - only VBUS detection and optional ESD protection diodes are recommended.
What is the maximum number of CapSense® electrodes supported on this device?
CY8C3244PVI-133T supports up to 62 self-capacitive or mutual-capacitive touch sensors using its dedicated CapSense® subsystem and all 29 GPIOs. This includes support for sliders, wheels, and proximity sensing - enabled by SmartSense™ auto-tuning that dynamically adjusts scan parameters without host firmware intervention.
Can the internal Delta-Sigma ADC perform simultaneous sampling on multiple channels?
No. The single Delta-Sigma ADC block supports sequential scanning across up to 20 analog inputs (via AMUXBUS routing), but lacks true simultaneous sampling. However, its 12-bit resolution, ±1 LSB INL, and 66 dB SINAD allow high-fidelity acquisition of slow-varying sensor signals like temperature or pressure when combined with external sample-and-hold if needed.
Is the 48-SSOP package RoHS-compliant and lead-free?
Yes. CY8C3244PVI-133T is manufactured in a lead-free, RoHS-compliant 48-SSOP package (PVI suffix), with matte tin finish and JEDEC-standard reflow profile compatibility (peak temperature ≤260°C). Full compliance documentation, including substance declarations and test reports, is available via Infineon's product change notifications (PCNs).
