Product details
Overview
CY7C65214D from Infineon Technologies (formerly Cypress Semiconductor) is a USB 2.0 Full-Speed (12 Mbps) dual-channel SPI bridge controller with integrated 48-MHz oscillator, battery charger detection (BCD v1.2), and 8 GPIOs. It operates from 1.71–5.5 V, supports commercial (0–70°C) and industrial (−40–85°C) temperature ranges, and delivers up to 3 MHz SPI master and 1 MHz SPI slave data rates per channel.
For engineers reviewing the CY7C65214D datasheet, CY7C65214D pinout, CY7C65214D application, or CY7C65214D equivalent, key selection criteria include dual SPI channel configurability, BCD-compliant peripheral detection, vendor-class USB protocol support, and QFN-32 package compatibility with legacy peripheral interface upgrades.
Technical Context
The CY7C65214D implements a dual Serial Communication Block (SCB) architecture-each SCB independently configurable as SPI master or slave-with dedicated 256-byte TX/RX FIFOs per channel. It uses an internal 48-MHz oscillator for USB timing and includes a dedicated Battery Charger Detection (BCD) block compliant with USB BC 1.2 for peripheral-side charging identification.
USB enumeration occurs via vendor device class (not CDC), requiring Cypress-provided drivers or custom host software. Configuration is performed offline using the Windows-based Cypress USB-Serial Configuration Utility, which programs VID/PID, SPI mode (Motorola/TI/National), data width (4–16 bits), and GPIO mapping without firmware recompilation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-Speed (12 Mbps); enables direct connection to standard USB 2.0 hosts without external PHY. |
| SPI Channels | Dual independent channels; allows simultaneous bridging to two separate SPI peripherals (e.g., sensor + display). |
| SPI Data Rate | Up to 3 MHz (master), 1 MHz (slave); supports common sensor and memory interfaces without clock stretching. |
| SPI Data Width | 4–16 bits per transfer; accommodates legacy 8-bit microcontrollers and modern 16-bit ADCs or DACs. |
| Buffer Size | 256 bytes TX/RX per channel; reduces host polling frequency and improves throughput in burst-mode transfers. |
| GPIO Count | 8 pins; configurable as inputs/outputs or assigned to SPI chip-select, interrupt, or status signaling. |
| Operating Voltage | 1.71–5.5 V; permits direct interfacing with 1.8 V, 3.3 V, and 5 V logic domains without level shifters. |
| ESD Rating | 2.2 kV HBM; meets IEC 61000-4-2 Level 2 for board-level robustness in industrial environments. |
Pinout & Package
Package: 32-pin QFN (5 × 5 × 1 mm, 0.5 mm pitch), RoHS-compliant, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDD | Digital supply | Core logic voltage (1.71–5.5 V); powers USB transceiver, SCBs, and GPIOs. |
| VCCD | I/O supply | Configurable I/O voltage domain; sets output drive strength and input threshold for GPIO/SPI pins. |
| USBDP / USBDM | USB differential pair | Integrated 1.5 kΩ pull-up on USBDP enables Full-Speed enumeration; no external resistors required. |
| nXRES | Active-low reset | Asynchronous hardware reset; asserts internal state machines and clears FIFOs upon deassertion. |
| GND | Ground reference | Common return for digital, analog, and USB sections; requires low-impedance connection to thermal pad. |
| VBUS | USB bus power sense | Monitors host-supplied 4.4–5.25 V; enables self-powered mode detection and BCD peripheral classification. |
| GPIO[0:7] | General-purpose I/O | Software-configurable; can serve as SPI chip-select, interrupt request, or status indicator outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent SPI interfaces | Enables concurrent communication with two separate SPI slaves (e.g., flash memory and environmental sensor) without host CPU arbitration. |
| Battery Charging Detection (BCD) | Identifies downstream charging ports (SDP/CDP/DCP) per USB BC 1.2 spec; critical for portable medical and POS devices needing reliable power negotiation. |
| No-firmware configuration | Windows utility writes settings directly to on-chip flash; eliminates embedded firmware development and validation overhead for USB interface layer. |
| Integrated 48-MHz oscillator | Removes need for external crystal or clock source; reduces BOM count and PCB area while ensuring USB timing compliance. |
| Vendor-class USB protocol | Appears as custom USB device-not virtual COM port-enabling proprietary host applications with full control over data framing and error handling. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-to-SPI bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65216D | 12 GPIOs vs. 8; same dual SPI capability; no BCD support | Lacks battery charger detection; unsuitable for portable devices requiring USB power negotiation | Select when additional GPIOs are needed for chip-select or status signaling, and BCD is not required. |
| CY7C65215A | 17 GPIOs; adds USB-I2C and USB-UART modes; supports RS485 | Multi-protocol flexibility increases firmware complexity; larger footprint and cost | Choose when future expansion to I²C or UART peripherals is anticipated, and higher GPIO count justifies added cost. |
Compared with CY7C65216D and CY7C65215A, the CY7C65214D offers optimal balance of dual SPI functionality, BCD support, compact QFN-32 footprint, and minimal GPIO count-ideal for cost-sensitive, power-aware USB peripheral upgrades where protocol simplicity and USB compliance are primary requirements.

FAQ
Does the CY7C65214D support CDC (Virtual COM Port) mode?
No. The CY7C65214D defaults to USB vendor device class and requires Cypress-provided drivers or custom host applications. It does not enumerate as a CDC-compliant COM port. For CDC support, consider CY7C65213A or CY7C65211A instead.
Can both SPI channels operate simultaneously in master mode?
Yes. Each Serial Communication Block (SCB) is independently configurable. Both channels can be set as SPI masters, allowing concurrent communication with two separate SPI slaves-such as a flash memory and a temperature sensor-without host intervention.
What is the role of the VCCD pin, and how should it be connected?
VCCD supplies the I/O voltage for GPIO and SPI pins. It must be connected to the target peripheral's logic voltage (e.g., 3.3 V or 1.8 V). This pin sets output drive strength and input thresholds, enabling direct interfacing with mixed-voltage systems without external level shifters.
Is external clocking required for USB or SPI operation?
No. The CY7C65214D integrates a 48-MHz oscillator for USB timing and derives SPI clocks internally. No external crystal, oscillator, or clock source is needed-reducing BOM cost and simplifying layout while maintaining USB 2.0 Full-Speed compliance.
