Product details
Overview
CY8C5365LTI-104 from Infineon Technologies (acquired Cypress Semiconductor) is a programmable system-on-chip (PSoC® 5) integrating a 32-bit ARM Cortex-M3 CPU core, 256 KB flash, 64 KB SRAM, 12-bit SAR ADC (700 ksps), dual 8-bit DACs (5.5 Msps), and 24 UDB-based digital peripherals. It operates from 2.7 V to 5.5 V, supports CapSense® on GPIO, and targets embedded control with mixed-signal acquisition in industrial HMI and sensor fusion systems.
For engineers reviewing the CY8C5365LTI-104 datasheet, CY8C5365LTI-104 pinout, CY8C5365LTI-104 application, or CY8C5365LTI-104 equivalent, key selection criteria include its 67 MHz CPU clock, 46 GPIO with analog routing capability, USB 2.0 FS support, low-power hibernate mode (300 nA), and configurable analog blocks (PGA/TIA/mixer) for signal conditioning without external components.
Technical Context
The device implements a hierarchical architecture with a Cortex-M3 CPU subsystem tightly coupled to a programmable digital subsystem (24 UDBs + DSI routing) and a high-accuracy analog subsystem (1.024 V ±1% reference, SAR ADC, dual DACs, opamps, SC/CT blocks). All GPIOs support analog input/output routing via dedicated analog interconnect.
Digital peripherals are instantiated in UDBs using PSoC Creator™, enabling hardware-level configuration of timers, PWMs, UART/SPI/I²C, CRC, PRS, and quadrature decoders. Analog functions-including PGA gain control, TIA transimpedance scaling, and mixer-based signal modulation-are implemented in reconfigurable SC/CT blocks with direct connection to ADC/DAC paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F, 72 MHz, 256 KB flash, but no integrated CapSense® or SC/CT analog blocks; relies on external opamps for TIA. | Lacks native capacitive sensing and programmable analog front-end - requires additional components for touch or precision sensor interfaces. | Choose when floating-point math or DSP acceleration is prioritized over analog configurability and BOM reduction. |
| MAX32660 | ARM Cortex-M4, 96 MHz, ultra-low-power (1.6 µA/MHz), but only 32 KB flash, no USB PHY, and limited analog routing (12-bit ADC only). | No USB interface or GPIO-level DAC output - unsuitable for host-connected devices requiring HID/CDC class compliance. | Prefer for battery-powered wearables where runtime dominates over mixed-signal integration and USB connectivity. |
Compared with STM32F303VCT6 and MAX32660, CY8C5365LTI-104 uniquely combines USB 2.0 FS, CapSense®, and reconfigurable analog blocks in one die - delivering lowest component count for touch-enabled sensor hubs requiring both precision analog acquisition and host communication.

FAQ
Does CY8C5365LTI-104 support USB device enumeration without external crystal?
No. Full-Speed USB 2.0 operation requires a 24 MHz external crystal connected to XTAL_IN/XTAL_OUT. The internal IMO cannot meet USB timing jitter requirements. This crystal also feeds the PLL for CPU clock generation at 48 or 67 MHz, ensuring synchronous USB frame timing and accurate data transfer.
Can all 60 GPIO pins be used simultaneously for analog input with the SAR ADC?
No. While all GPIOs support analog routing, the SAR ADC has a single sample-and-hold circuit and multiplexed input path. Up to 62 analog inputs can be scanned sequentially via the analog mux, but only one channel is converted per acquisition cycle. Simultaneous sampling requires external analog front-end or UDB-based time-interleaved logic.
What is the maximum achievable resolution for a software-configured PWM DAC using UDBs?
Using UDB-based PWM generation with 10-bit counter depth and dithering, the effective resolution reaches 10 bits at ≤48 kHz update rate. This exceeds the 8-bit native VDAC resolution and supports higher-precision analog output for audio or calibration signals, though linearity depends on external RC filter design and clock stability.
Is the hibernate mode (300 nA) compatible with wake-up from CapSense® activity?
Yes. The device supports CapSense® wake-up from hibernate mode using the dedicated CSD block and low-power ILO clock. Only the CSD hardware remains active during hibernate, scanning electrodes at reduced resolution and frequency, then asserting an interrupt to restore full operation upon touch detection.
