Product details
Overview
CY8C3866PVI-070 from Infineon Technologies (formerly Cypress) is a programmable 8-bit PSoC® 3 system-on-chip integrating an 8051 CPU, configurable analog/digital peripherals, 64 KB flash, 8 KB RAM, and full CAN 2.0b interface. It operates from 1.71–5.5 V at up to 67 MHz, supports CapSense® for up to 62 sensors, and delivers ultra-low-power operation down to 200 nA in hibernate mode with RAM retention - deployed in industrial HMI, medical sensor hubs, and automotive body control modules.
For engineers reviewing the CY8C3866PVI-070 datasheet, CY8C3866PVI-070 pinout, CY8C3866PVI-070 application, or CY8C3866PVI-070 equivalent, key selection criteria include its 72-pin TQFP package, integrated DFB digital filter processor, USB 2.0 Full-Speed peripheral, 4-channel delta-sigma ADC (8–20-bit), and programmable UDB array enabling custom logic synthesis without external glue logic.
Technical Context
The CY8C3866PVI-070 implements a unified mixed-signal architecture where analog and digital resources are routed flexibly via Digital System Interconnect (DSI) and Analog Routing Matrix (ARM). Its 24-channel DMA controller offloads the 8051 core during high-throughput data transfers, while the 24-bit 64-tap Digital Filter Block (DFB) enables real-time FIR/IIR filtering without CPU intervention.
It features four independent 16-bit TCPWM blocks supporting timer/counter/PWM modes, full CAN 2.0b with 16 Rx and 8 Tx buffers, and a programmable clock tree with internal PLL (up to 67 MHz), low-power oscillators (1/33/100 kHz), and 32.768-kHz watch crystal support - all managed through dedicated system registers and PSoC Creator™ configuration tools.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C5868LTI-LP097 | 32-bit ARM Cortex-M3 core, 256 KB flash, higher clock (80 MHz), no integrated CAN, USB only as device (no host) | Targets higher-performance applications requiring RTOS, complex connectivity (BLE/Wi-Fi coexistence), but lacks native CAN bus support | Select when migrating to ARM ecosystem and CAN is handled externally or via software stack |
| STM32F303VCT6 | ARM Cortex-M4F core, 256 KB flash, 48 KB RAM, integrated CAN, no CapSense® or programmable analog, fixed peripheral set | Suitable for deterministic motor control with FPU and DSP instructions, but requires external touch controller and ADC for sensor fusion | Select when deterministic floating-point math and motor control peripherals (advanced timers, opamp-comparator combos) are primary requirements |
Compared with CY8C3866PVI-070, the CY8C5868LTI-LP097 offers greater compute headroom but sacrifices integrated CAN and CapSense®, while the STM32F303VCT6 provides stronger analog/motor control features but lacks reconfigurable logic and unified mixed-signal routing - making CY8C3866PVI-070 optimal for cost-sensitive, highly integrated embedded control with touch and fieldbus interfaces.

FAQ
Does CY8C3866PVI-070 support USB host functionality?
No. The CY8C3866PVI-070 implements only USB 2.0 Full-Speed peripheral mode (device-only), certified under TID#40770053. It cannot act as a USB host to enumerate external devices like flash drives or HID peripherals. Host capability requires external USB host controller or migration to PSoC 4/5LP families with dual-role USB support.
What is the maximum operating temperature for continuous use?
The CY8C3866PVI-070 is rated for ambient temperatures from –40 °C to +85 °C under continuous operation. Its thermal design supports junction temperatures up to 125 °C, verified per JEDEC JESD22-A104 reliability testing. Derating is required above 85 °C ambient unless board-level thermal management is implemented.
Can the internal DFB perform FFT operations?
No. The Digital Filter Block (DFB) is a fixed-function 24-bit 64-tap FIR/IIR engine optimized for real-time linear filtering (e.g., notch, low-pass, band-pass). It does not support FFT computation, which requires complex arithmetic and butterfly structures beyond its architecture. FFT must be implemented in firmware on the 8051 core or offloaded to external DSP.
Is CapSense® supported on all GPIO pins?
Yes. All 62 general-purpose I/O pins support CapSense® functionality, either as self-capacitance (CSD) or mutual-capacitance (CSX) sensors. Pin assignment is fully configurable in PSoC Creator™, and routing is validated through built-in CapSense® tuning tools that auto-calibrate baseline, sensitivity, and noise rejection per channel.
