Product details
Overview
CY8C3444PVA-100 from Infineon Technologies (acquired Cypress Semiconductor) is an AEC-Q100 qualified automotive-grade PSoC® 3 programmable system-on-chip integrating an 8051 CPU core, 64 KB flash, 8 KB SRAM, 2 KB EEPROM, 24-channel DMA, full CAN 2.0b interface (16 Rx/8 Tx), USB 2.0 Full-Speed peripheral, and configurable analog/digital peripherals - deployed in engine control units, body electronics, and ADAS sensor interfaces.
For engineers reviewing the CY8C3444PVA-100 datasheet, CY8C3444PVA-100 pinout, CY8C3444PVA-100 application, or CY8C3444PVA-100 equivalent, key selection criteria include its 100-pin TQFP package, –40 °C to +125 °C extended temperature rating, integrated delta-sigma ADC (12-bit, 192 ksps, 66 dB SINAD), dual opamps (25 mA drive), and CAN+USB coexistence on a single die.
Technical Context
The CY8C3444PVA-100 implements a hardened 8051 microcontroller core with single-cycle execution, supporting DC–50 MHz operation, multiply/divide instructions, and 512-byte flash cache. Its memory subsystem includes 64 KB flash (100k write cycles, 20-year retention), 8 KB SRAM, and 2 KB EEPROM (1M cycles).
Analog functionality centers on a configurable delta-sigma ADC (8–12-bit, ×0.25–×16 PGA gain, 192 ksps max), four comparators (95 ns response), two uncommitted opamps, and two SC/CT blocks usable as PGA, TIA, or mixer. Digital resources include 24 UDBs, four 16-bit timer/counter/PWM blocks, and dedicated CAN 2.0b and USB 2.0 FS controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core, 160 MHz, no integrated USB; CAN FD support instead of CAN 2.0b; larger flash (512 KB) but no on-die delta-sigma ADC. | Better suited for high-speed CAN FD networks and complex motor control; lacks integrated high-resolution ADC for analog sensor aggregation. | Select when CAN FD, floating-point math, or larger code footprint is required - not for legacy CAN-only or high-precision analog acquisition. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz, integrated 10-bit SAR ADC (1 Msps), no USB or CAN; lower power (120 nA hibernate) but limited analog flexibility. | Targeted at cost-sensitive body electronics with basic analog sensing; lacks CapSense®, SC/CT blocks, and USB diagnostics capability. | Choose for simple BCM functions where USB/CAN integration and configurable analog are unnecessary - avoids PSoC's design tool overhead. |
Compared with NXP S32K144 and Renesas RL78/F14, the CY8C3444PVA-100 uniquely combines automotive-grade CAN 2.0b, USB 2.0 FS, and a configurable delta-sigma ADC in one die - enabling sensor hub and diagnostic gateway functions without external analog or interface ICs.

FAQ
Is CY8C3444PVA-100 pin-compatible with other CY8C34 devices?
Yes - all 100-pin TQFP variants in the CY8C34 family (e.g., CY8C3446PVA-100, CY8C3447PVA-100) share identical pinouts and mechanical footprints. Electrical differences (e.g., flash size, peripheral enablement) are masked by firmware configuration, enabling hardware reuse across product variants.
Does CY8C3444PVA-100 support ISO 26262 functional safety certification?
The device itself is not ASIL-certified, but it provides foundational safety mechanisms required for ASIL-B development: ECC on flash/SRAM, lockable registers, memory protection unit (MPU), and fault-tolerant clock monitoring. Customers implement ASIL-B compliance via PSoC Creator™ safety libraries and FMEDA analysis per ISO 26262 Part 5.
Can the on-chip USB interface operate without an external crystal?
Yes - the USB 2.0 Full-Speed PHY uses an internal 48 MHz oscillator trimmed to ±0.25% accuracy, eliminating need for external crystal or load capacitors. This reduces BOM cost and improves USB EMI performance in automotive environments.
What development tools are required to program CY8C3444PVA-100?
PSoC Creator™ IDE (discontinued but supported) or ModusToolbox™ 3.x with PSoC 3 device support packages. Programming uses standard SWD/JTAG via KitProg3 or MiniProg3 debug probes. Bootloader support enables field updates over UART, I²C, SPI, or USB without JTAG access.
