Product details
Overview
CY8C3444PVE-118 from Infineon Technologies (acquired Cypress Semiconductor) is an AEC-Q100 qualified automotive-grade PSoC® 3 programmable system-on-chip integrating an 8051 CPU core, up to 64 KB flash, 8 KB SRAM, 2 KB EEPROM, 24-channel DMA, full CAN 2.0b interface, USB 2.0 Full-Speed peripheral, and configurable analog/digital peripherals - all in a 100-pin TQFP package rated for –40 °C to +125 °C operation.
For engineers reviewing the CY8C3444PVE-118 datasheet, CY8C3444PVE-118 pinout, CY8C3444PVE-118 application, or CY8C3444PVE-118 equivalent, this device supports rapid mixed-signal system integration with CapSense®, delta-sigma ADC (12-bit, 192 ksps), programmable UDB logic, and multi-domain I/O voltage support (1.2–5.5 V), enabling firmware-driven reconfiguration without hardware changes.
Technical Context
The CY8C3444PVE-118 implements a single-cycle 8051 microcontroller core operating at DC to 50 MHz, backed by 512-byte flash cache and ECC-protected configuration storage. Its digital subsystem centers on 24 universal digital blocks (UDBs) supporting configurable logic, timers, PWMs, CRC, PRS, LIN, and quadrature decoding via DSI routing.
Analog functionality includes a 12-bit delta-sigma ADC (66 dB SINAD, ±1 LSB INL/DNL), four comparators (95 ns response), two opamps (25 mA drive), two SC/CT blocks (configurable as PGA/TIA/mixer), and dual 8-bit DACs (8 Msps IDAC / 1 Msps VDAC), all accessible through 62 GPIOs with full analog/digital signal routing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon CY8C3866AXI-065 | Higher memory (128 KB flash, 16 KB SRAM), additional USB HS support, same UDB count and analog specs. | Better suited for complex HMI or gateway applications requiring larger code footprint and faster USB throughput. | Select when >64 KB flash or USB 2.0 High-Speed is required; otherwise CY8C3444PVE-118 offers optimal cost/performance for mid-tier automotive nodes. |
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, CAN FD support, higher clock (112 MHz), but lacks integrated CapSense® and programmable analog blocks. | Preferred for safety-critical ASIL-B applications with RTOS and CAN FD networking, but requires external analog signal chain. | Choose for functional safety compliance (ISO 26262) and CAN FD; avoid if analog configurability or touch integration is essential. |
Compared with CY8C3866AXI-065 and S32K144HAT0MLHT, the CY8C3444PVE-118 uniquely balances automotive qualification, analog/digital configurability, and cost efficiency - delivering CapSense®, delta-sigma ADC, and UDB logic in a single die where mixed-signal flexibility outweighs raw compute or safety certification needs.

FAQ
Is CY8C3444PVE-118 pin-compatible with other CY8C34xx devices?
Yes - it shares the 100-pin TQFP package and pinout with CY8C3445/3446/3447 variants in the same package option. Pin assignments for VDDIO domains, GPIOs, CAN, USB, and reset are identical; only flash/SRAM/EEPROM sizes and peripheral enablement differ per part number.
Does CY8C3444PVE-118 support CAN FD?
No - it implements classical CAN 2.0b only (16 Rx/8 Tx buffers, bit rates up to 1 Mbps). CAN FD capability is not present in the CY8C34 family; that feature appears in later PSoC 4 and Traveo™ families or Infineon's AURIX™ MCUs.
Can the internal 1.024 V reference be used for external circuits?
Yes - the 1.024 V ±0.1% internal voltage reference is accessible on the VREF pin and can source up to 100 µA. It is specified across –40 °C to +85 °C and supports external ADC reference or precision biasing of opamp circuits.
What debug interfaces does CY8C3444PVE-118 support?
It supports JTAG (4-wire), Serial Wire Debug (SWD, 2-wire), and Single Wire Viewer (SWV) for real-time trace. Debug features include 8 address breakpoints, 1 data breakpoint, and a 4 KB instruction trace buffer - compatible with standard ARM-compatible debug probes.
