Product details
Overview
CYWB0164BB-BZXI from Infineon Technologies is a West Bridge USB host controller IC designed to offload USB 2.0 protocol handling from main processors in embedded systems. It supports up to four USB 2.0 downstream ports, integrates a 32-bit ARM7TDMI core, and features 128 KB on-chip SRAM. Used in industrial HMIs and medical data acquisition devices requiring deterministic USB peripheral management.
For engineers reviewing the CYWB0164BB-BZXI datasheet, CYWB0164BB-BZXI pinout, CYWB0164BB-BZXI application, or CYWB0164BB-BZXI equivalent, key selection criteria include integrated ARM7 core execution, USB 2.0 host stack offload capability, 121-ball FBGA package compatibility, and support for USB mass storage and HID class devices.
Technical Context
The CYWB0164BB-BZXI implements a dedicated USB 2.0 host controller with full-speed and high-speed device support, using an embedded ARM7TDMI CPU running at 60 MHz. It includes hardware accelerators for USB protocol parsing, endpoint management, and descriptor handling.
It interfaces via a 16-bit parallel host bus (with DMA support) or SPI, and provides configurable GPIOs for reset, suspend/resume signaling, and port power control. The device requires external 1.8 V and 3.3 V supplies and operates across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed Support | Full-speed (12 Mbps) and high-speed (480 Mbps) host operation - enables direct connection to legacy and modern USB peripherals without external transceivers. |
| Integrated Core | ARM7TDMI @ 60 MHz - executes USB host stack firmware independently, reducing host CPU load and latency in real-time systems. |
| On-chip Memory | 128 KB SRAM - stores USB descriptors, endpoint buffers, and firmware code, eliminating need for external RAM in basic configurations. |
| Package | 121-ball FBGA (8 mm × 8 mm, 0.8 mm pitch) - surface-mount compatible with standard PCB assembly processes and thermal management for industrial environments. |
| Operating Temperature | –40°C to +85°C - qualified for use in extended-temperature industrial and medical equipment without derating. |
| Host Interface | 16-bit parallel bus with DMA or SPI - allows flexible integration with microcontrollers or ASICs lacking native USB host controllers. |
Pinout & Package
121-ball Fine-Pitch Ball Grid Array (FBGA) package with 0.8 mm ball pitch, 8 mm × 8 mm body size, and standard JEDEC MO-275AC footprint. Thermal pad exposed on underside for enhanced heat dissipation in continuous USB host operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO_3V3 | I/O Power Supply | Supplies 3.3 V to USB PHY and interface pins; must be decoupled with 100 nF ceramic capacitor near ball. |
| VDD_CORE_1V8 | Core Power Supply | Provides 1.8 V to ARM7 core and internal logic; requires low-noise regulation and local 1 µF + 100 nF filtering. |
| USB_DP / USB_DM | USB 2.0 Differential Pair | Direct connection to USB upstream port; requires 90 Ω differential impedance trace routing and ESD protection diodes. |
| HST_nCS | Host Chip Select | Active-low enable for parallel host interface; asserted during memory-mapped register access cycles. |
| SPI_SCLK / SPI_MOSI / SPI_MISO / SPI_nSS | SPI Interface Signals | Enable firmware update and configuration over 4-wire SPI; supports up to 25 MHz clock for fast programming. |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated USB 2.0 Host Stack Firmware | Pre-integrated, field-upgradable firmware handles enumeration, transaction scheduling, and error recovery - eliminates need for host-side USB stack development. |
| Four Downstream USB Ports | Supports simultaneous connection of up to four USB peripherals (e.g., keyboard, flash drive, printer, camera) with individual port power control. |
| Hardware USB Descriptor Engine | Offloads descriptor parsing and generation from ARM7 core - reduces CPU utilization by ~35% during device enumeration. |
| Configurable GPIO Bank | 16 general-purpose I/Os with interrupt capability - used for port enable/disable, reset signaling, and status LED control without external logic. |
Applications
| Industrial HMI Systems | Medical Data Loggers |

Use Value: Achieves sub-millisecond inter-device synchronization accuracy without FPGA or custom timing ASIC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB host controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress CY7C68013A-56PVXC | USB 2.0 FX2LP microcontroller with 8051 core; no integrated USB host stack firmware - requires external firmware development. | Targeted at low-cost, high-volume consumer peripherals rather than industrial embedded host applications. | Select only if full firmware control and minimal BOM cost are prioritized over time-to-market and deterministic USB behavior. |
| NXP ISP1583 | Standalone USB 2.0 host controller without embedded CPU; relies entirely on external host processor for stack execution. | Used in PC add-in cards and legacy x86-based test equipment where host CPU resources are abundant. | Choose when existing host software already includes mature USB host stack and external memory bandwidth is sufficient for descriptor handling. |
Compared with CY7C68013A-56PVXC and ISP1583, CYWB0164BB-BZXI uniquely delivers pre-validated USB host functionality with integrated ARM7 core and firmware - reducing system-level validation effort and enabling faster certification in regulated industrial and medical deployments.

FAQ
Does CYWB0164BB-BZXI support USB On-The-Go (OTG)?
No. CYWB0164BB-BZXI is a dedicated USB 2.0 host-only controller and does not implement USB OTG dual-role functionality. It lacks the ID pin detection circuitry and peripheral-mode firmware required for OTG operation. Applications requiring device/host switching must use separate OTG-capable ICs.
What firmware development tools are supported?
Infineon provides the West Bridge Software Development Kit (SDK), including ARM7-compatible GCC toolchain, USB class drivers (HID, MSC, CDC), and JTAG-based debug interface support via ULINK2 or Segger J-Link. No proprietary IDE is required.
Is external USB PHY required?
No. CYWB0164BB-BZXI integrates a fully compliant USB 2.0 transceiver with internal termination and slew-rate control. Only passive ESD protection diodes (e.g., NUP4114) are needed on USB_DP/DM lines per Infineon's layout guidelines.
Can it operate with only 3.3 V supply?
No. The device requires two independent supplies: 1.8 V for the core logic and 3.3 V for I/O and USB PHY. Both rails must be present and sequenced - VDD_CORE must stabilize before VDDIO - per the power-on reset timing requirements in the datasheet.
