Product details
Overview
CY8C3445PVA-094 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-including delta-sigma ADC (12-bit, 192 ksps), four comparators (95 ns), two opamps, and CapSense® support-targeting engine control units, body electronics, and ADAS sensor interfaces.
For engineers reviewing the CY8C3445PVA-094 datasheet, CY8C3445PVA-094 pinout, CY8C3445PVA-094 application, or CY8C3445PVA-094 equivalent, key selection criteria include AEC-Q100 Grade 2 qualification (–40 °C to +105 °C), 100-pin TQFP package with 62 GPIOs, CAN/USB dual-interface capability, programmable UDB array for custom logic, and integrated analog subsystem supporting thermocouple-to-ultrasonic signal acquisition.
Technical Context
The CY8C3445PVA-094 implements a single-cycle 8051 microcontroller core operating at DC to 50 MHz, backed by flash memory (64 KB, 100K write cycles, 20-year retention), ECC-capable configuration storage, and 24-channel DMA with multilayer AHB bus access and programmable descriptor chaining. Its digital subsystem centers on 24 universal digital blocks (UDBs) enabling reconfigurable logic, timers, PWMs, CRC, PRS, LIN, and quadrature decoding.
Analog functionality includes a 1.024 V ±0.1% internal reference, delta-sigma ADC (8–12-bit, 192 ksps, 66 dB SINAD in 12-bit mode), four fast comparators (95 ns), two uncommitted opamps (25 mA drive), and two multifunction SC/CT blocks supporting PGA, TIA, mixer, and sample-and-hold configurations-all routable to any of 62 GPIO pins.

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, 128 KB flash, no integrated delta-sigma ADC; relies on external SAR ADC for high-precision analog | Targeted at safety-critical ASIL-B applications with ISO 26262 support; lacks CapSense® and analog configurability | Select when functional safety certification (ASIL-B) is mandatory and ARM ecosystem tooling is preferred over PSoC Creator |
| Renesas RL78/F14 | 16-bit RL78 core, 256 KB flash, 10-bit SAR ADC (1 Msps), no CAN FD or USB; lower integration density | Optimized for cost-sensitive body electronics with basic CAN/LIN; no USB or CapSense® capability | Select for low-cost, low-power BCM designs where USB/CapSense® are unnecessary and 10-bit ADC resolution suffices |
Compared with NXP S32K144 and Renesas RL78/F14, CY8C3445PVA-094 delivers higher analog integration (delta-sigma ADC, opamps, SC/CT blocks), embedded CapSense®, and USB 2.0 FS-making it optimal for non-ASIL automotive HMI and sensor fusion nodes where firmware-driven flexibility outweighs safety certification overhead.

FAQ
Does CY8C3445PVA-094 support CAN FD?
No. CY8C3445PVA-094 implements only classical CAN 2.0b (ISO 11898-1) with 16 Rx and 8 Tx message buffers. It does not support CAN FD frame format, bit rate switching, or extended data length. For CAN FD, consider Infineon's TRAVEO™ T2G or AURIX™ families.
What development tools are required to program this device?
PSoC Creator™ IDE (v4.4 or later) is mandatory for schematic-based design, component configuration, and code generation. Programming requires a MiniProg3 or KitProg2 debugger via SWD interface; USB-based bootloader updates are supported through UART, I2C, SPI, or native USB HID class.
Is the internal 1.024 V reference usable for external ADC calibration?
Yes. The 1.024 V ±0.1% internal voltage reference is routed to dedicated REF_IN/REF_OUT pins and is specified across –40 °C to +85 °C. It can serve as a precision calibration source for external SAR or sigma-delta converters when buffered via the on-chip opamp.
Can all 62 GPIOs simultaneously function as analog inputs?
No. While all 62 GPIOs support analog routing, the delta-sigma ADC has only one sampling channel with multiplexed inputs. Up to 62 analog sources may be connected, but only one is sampled at a time. Simultaneous sampling requires external analog multiplexers or parallel ADCs.
