Product details
Overview
CY8C3866PVA-070 from Infineon Technologies (formerly Cypress) 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, and configurable analog/digital peripherals including CAN 2.0b, USB 2.0 Full-Speed, delta-sigma ADC (20-bit, 192 ksps), four opamps, and CapSense® support. It operates from 1.71 V to 5.5 V across –40 °C to +85 °C in a 100-pin TQFP package and targets embedded control with mixed-signal acquisition and real-time processing.
For engineers reviewing the CY8C3866PVA-070 datasheet, CY8C3866PVA-070 pinout, CY8C3866PVA-070 application, or CY8C3866PVA-070 equivalent, this device serves as a single-chip solution for automotive body electronics, industrial sensor hubs, and medical instrumentation requiring high-accuracy analog front-ends, deterministic timing, and field-upgradable firmware without hardware redesign.
Technical Context
The CY8C3866PVA-070 implements a hardened 8051 microcontroller core running at up to 67 MHz with single-cycle execution, 512-byte flash cache, and ECC-protected flash configuration storage. Its digital subsystem centers on 24 Universal Digital Blocks (UDBs) supporting reconfigurable logic, timers, PWMs, I²C, LIN, and full CAN 2.0b with 16 Rx/8 Tx buffers - all routed flexibly via the Digital System Interconnect (DSI) to any GPIO.
Analog functionality includes a 1.024 V ±0.1% internal reference, a delta-sigma ADC with programmable gain (×0.25–×16) and resolution modes (8–20-bit), four rail-to-rail opamps (25 mA drive), four comparators (95 ns response), and four SC/CT blocks configurable as PGA, TIA, or mixer. All analog resources operate over 1.71–5.5 V VDDA and are temperature-compensated per AEC-Q100 requirements.

FAQ
Is CY8C3866PVA-070 pin-compatible with other CY8C38 family members?
Yes - CY8C3866PVA-070 uses the 100-pin TQFP package shared across CY8C3866xxx variants. Pin functions are consistent per the CY8C38 Automotive Family Datasheet Rev. *L, Section 2 (Pinouts) and Section 3 (Pin Descriptions). Differences exist only in peripheral enablement (e.g., USB/CAN presence), not physical layout or electrical pin behavior.
Does CY8C3866PVA-070 support USB device enumeration without external crystal?
Yes - it integrates a factory-trimmed internal oscillator qualified for USB Full-Speed (12 Mbps) operation, certified under TID#40770053. No external crystal is required for basic USB device functionality, though a 24 MHz crystal improves timing margin for high-bandwidth transfers.
What is the maximum operating frequency of the delta-sigma ADC in CY8C3866PVA-070?
The delta-sigma ADC achieves up to 192 ksps in 12-bit mode with 66 dB SINAD and ±1-bit INL/DNL. At 20-bit resolution, the maximum sample rate drops to 12 ksps. These values are guaranteed for VDDA ≥ 2.7 V, as specified in Table 11-17 of the datasheet.
Can the four opamps be used simultaneously with the delta-sigma ADC?
Yes - all four opamps and the delta-sigma ADC share the same analog subsystem resources but operate independently. The ADC's input multiplexer supports routing from any opamp output or GPIO, and opamp configurations (e.g., PGA, TIA) are fully compatible with ADC acquisition timing and reference stability.
