Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560B50L3 | 32-bit Power Architecture core, no integrated USB or CapSense®, higher power consumption (20 mA @ 64 MHz), 12-bit SAR ADC only. | Targeted at engine control units requiring ASIL-B compliance; lacks flexible analog routing and touch integration. | Select when needing AUTOSAR stack support and higher computational throughput, but accept added external components for HMI functions. |
| TC375TA | TriCore™ 32-bit CPU, integrated Ethernet MAC, no on-chip USB or CapSense®, 12-bit SAR ADC with 1 Msps max, larger footprint (144-pin LQFP). | Designed for gateway ECUs with multi-protocol routing; requires external touch controller and USB transceiver. | Choose for high-bandwidth vehicle network bridging where USB/CapSense are secondary; prioritize real-time interrupt latency over analog flexibility. |
Compared with SPC560B50L3 and TC375TA, the CY8C3445PVA-090 delivers superior analog integration (delta-sigma ADC, opamps, SC/CT blocks), lower system-level BOM cost via CapSense® and LCD drive, and faster design iteration through PSoC Creator's graphical component library-making it optimal for cost-sensitive, function-rich automotive edge nodes.

FAQ
Does CY8C3445PVA-090 support USB device enumeration without an external crystal?
Yes. The part integrates a factory-trimmed internal main oscillator (IMO) that meets USB 2.0 Full-Speed timing requirements (±0.25% accuracy) across temperature and voltage. It is certified under TID#40770053 and requires no external crystal or resonator for USB operation.
What is the maximum number of simultaneous CapSense® buttons supported?
The CY8C3445PVA-090 supports up to 62 self-capacitive or mutual-capacitive buttons using any GPIO pin. With PSoC Creator's CapSense® CSD component, typical implementation achieves 20–30 buttons with 10-ms scan time and >100:1 signal-to-noise ratio at 10 Vpp sensor excitation.
Can the delta-sigma ADC perform simultaneous sampling on multiple channels?
No. The delta-sigma ADC uses a single conversion core with multiplexed inputs. However, its 192 ksps sample rate and programmable sequencer allow rapid interleaved sampling across up to 62 GPIO-connected channels with sub-5 µs channel switching and consistent phase alignment for sensor array correlation.
Is the CAN interface compatible with ISO 11898-2 physical layer standards?
Yes. The CY8C3445PVA-090's CAN TX/RX pins are electrically compatible with ISO 11898-2 and require only an external CAN transceiver (e.g., TJA1042) to complete the physical layer. The on-chip controller fully implements CAN 2.0b protocol with 16 receive and 8 transmit message objects and hardware acceptance filtering.
