Product details
Overview
CY8C3246FNI-213T from Infineon Technologies (acquired Cypress Semiconductor) is a programmable 8-bit PSoC® 3 mixed-signal SoC featuring an enhanced 50 MHz single-cycle 8051 CPU, 64 KB flash, 8 KB RAM, and configurable analog/digital peripherals including Delta-Sigma ADC, DAC, comparators, USB 2.0 FS interface, and CapSense® support for up to 62 sensors - deployed in industrial HMI, medical sensor nodes, and battery-powered IoT edge controllers.
For engineers reviewing the CY8C3246FNI-213T datasheet, CY8C3246FNI-213T pinout, CY8C3246FNI-213T application, or CY8C3246FNI-213T equivalent, key selection criteria include its 1.71–5.5 V operating range, 200 nA hibernate mode with RAM retention, 48-QFN package with 32 GPIOs and dual SIO pins, and USBIO-capable D+/D− routing - critical for low-power embedded control with integrated signal conditioning and human interface functionality.
Technical Context
The device implements a unified programmable architecture where analog and digital resources-including 24 UDBs, four 16-bit TCPWM blocks, and a dedicated USB 2.0 FS PHY-are routed via a flexible interconnect fabric to any of 32 GPIOs or 2 SIOs. Its clock system integrates a 3–24 MHz IMO (±2% at 3 MHz), 50 MHz PLL, and 32.768 kHz RTC support.
Analog subsystem operation centers on a 8–12-bit Delta-Sigma ADC (INL < ±1 LSB, SINAD > 66 dB), dual voltage comparators, 1.024 V ±1% reference, and 8-bit DAC (VDAC: 1 Msps, IDAC: 8 Msps), all accessible through shared analog buses and configurable I/O routing.

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 |
|---|---|---|---|
| CY8C3247FNI-223T | Same 48-QFN package; adds 16 KB additional flash (80 KB total) and 1 KB extra RAM (9 KB total) - no change in analog/digital peripheral count or clock specs. | Better suited for complex USB HID + CapSense + multi-sensor fusion firmware with larger code footprint. | Select when firmware exceeds 64 KB or requires extended data buffering without external memory. |
| CY8C4014LQI-422 | PSoC 4 (ARM Cortex-M0) variant in same 48-QFN; lower power (150 nA deep sleep), no USB FS PHY, reduced analog precision (12-bit SAR ADC, no Delta-Sigma), but higher CPU throughput (48 MHz). | Preferred for cost-sensitive, non-USB, high-throughput digital control tasks where analog precision is secondary. | Choose for new designs prioritizing ARM ecosystem compatibility and lowest active power, accepting trade-offs in analog performance and USB integration. |
Compared with CY8C3246FNI-213T, CY8C3247FNI-223T offers expanded memory for feature-rich firmware without altering peripheral capability, while CY8C4014LQI-422 shifts to ARM architecture with lower sleep current but sacrifices Delta-Sigma ADC fidelity and native USB 2.0 compliance - making the original optimal for legacy-compatible, analog-intensive, USB-enabled embedded control.

FAQ
What development tools are required to program and debug CY8C3246FNI-213T?
PSoC Creator™ IDE (free download from Infineon) is mandatory for hardware configuration and firmware development. Programming and debugging require MiniProg3 or KitProg2 programmer/debugger supporting SWD/SWV protocols. JTAG (4-wire) and SWD (2-wire) interfaces are supported; USBIO pins can also serve as SWDIO/SWDCK during debug sessions.
Does CY8C3246FNI-213T support true hardware USB enumeration without external crystal?
Yes - it includes a TID#40770053-certified USB 2.0 Full-Speed peripheral with an internal oscillator meeting USB timing requirements. No external 12 MHz crystal is needed for basic USB device operation, though an external crystal may improve jitter performance in high-noise environments.
Can the Delta-Sigma ADC operate simultaneously with USB data transfer?
Yes - the ADC and USB modules operate independently via separate clock domains and DMA channels. The PHUB DMA controller enables concurrent ADC sampling (triggered by TCPWM or timer) and USB data transmission without CPU intervention, maintaining real-time throughput in both subsystems.
Is the boost converter output (VBOOST) regulated and capable of powering external circuitry?
Yes - VBOOST delivers a regulated 5.0 V ±5% output from input voltages as low as 0.5 V, with up to 100 mA continuous current. It is electrically isolated from VDDIO domains and can directly power external sensors, LCD bias circuits, or level-shifting ICs without additional regulation.
