Product details
Overview
CYFB0072V18L-133BGXI from Cypress Semiconductor is a 72-Mbit ×36 video frame buffer FIFO with independent 133-MHz read/write ports, LVCMOS 1.8 V/3.3 V I/O support, and flow-through mailbox register for clock-domain bridging in high-speed video pipelines.
For engineers reviewing the CYFB0072V18L-133BGXI datasheet, CYFB0072V18L-133BGXI pinout, CYFB0072V18L-133BGXI application, or CYFB0072V18L-133BGXI equivalent, key selection criteria include simultaneous dual-clock operation (RCLK/WCLK ratio 0.5–2), empty/full flag synchronization, DVal timing alignment, and JTAG boundary scan capability for system-level validation.
Technical Context
The device implements a synchronous dual-port FIFO architecture with physically separate read and write address pointers, enabling true asynchronous data buffering across independent clock domains. It supports burst-aligned writes (minimum two words) and single-word reads, with flags (EF/FF) synchronized to respective clocks (RCLK/WCLK) and latency-critical DVal assertion aligned to output data edges.
Configuration is managed via parallel (LD-controlled) or serial SPI (SPI_SCLK/SPI_SI/SPI_SEN) interfaces, while JTAG (TCK/TMS/TDI/TDO) provides IEEE 1149.1-compliant boundary scan testing. Reset includes master (MRS) and partial (PRS) modes-MRS clears memory and config registers; PRS retains configuration while resetting pointers and flags.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density & Organization | 72-Mbit total capacity, ×36 bus width enabling 4.8 Gbps peak throughput at 133 MHz |
| Max Clock Frequency | 133 MHz for both RCLK and WCLK; supports up to 2:1 clock ratio between domains |
| I/O Voltage Support | LVCMOS 1.8 V core (VCC1) and 3.3 V I/O (VCCIO); dual-supply isolation prevents signal integrity degradation |
| Flag Synchronization | EF flag synchronized to RCLK; FF flag synchronized to WCLK-enables deterministic flag sampling per domain |
| Data Valid Timing | DVal active-low, edge-aligned to Q[35:0] on RCLK rising edge-eliminates need for REN-to-data latency tracking |
| Mailbox Bypass Latency | Flow-through mailbox (MB asserted) delivers D[35:0] to Q[35:0] in exactly two WCLK cycles-no memory array access required |
| Reset Modes | Master reset (MRS) clears memory + config registers; partial reset (PRS) retains config while resetting pointers/flags |
Pinout & Package
209-ball Fine-Pitch Ball Grid Array (FBGA) package, 13 mm × 13 mm, 0.8 mm pitch, RoHS-compliant, industrial temperature range (–40 °C to +85 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D[35:0] | Parallel data input bus | 36-bit wide write path; accepts data on WCLK rising edge when WEN and IE active |
| Q[35:0] | Parallel data output bus | 36-bit wide read path; outputs valid data synchronized to RCLK with DVal assertion |
| WCLK / RCLK | Independent clock inputs | Asynchronous clock domains-WCLK controls write pointer; RCLK controls read pointer |
| WEN / REN / OE / IE | Control enable signals | WEN/REN gate clocked transfers; OE enables Q[35:0] drivers; IE enables D[35:0] latching (write masking) |
| EF / FF | Status flag outputs | EF low = buffer empty (RCLK-synchronized); FF low = buffer full (WCLK-synchronized) |
| MB / DVal / LD / MRS / PRS | Functional control & status | MB enables mailbox bypass; DVal validates Q[35:0]; LD selects memory/config access; MRS/PRS reset logic |
| SPI_SCLK / SPI_SI / SPI_SEN | Serial configuration interface | 3-wire SPI port for non-volatile register programming without halting parallel operation |
| TCK / TMS / TDI / TDO | JTAG test interface | IEEE 1149.1 boundary scan for PCB interconnect verification and in-system debug |
Key Features
| Feature | Design Value |
|---|---|
| Independent Read/Write Clock Domains | Enables seamless video data bridging between disparate clock domains (e.g., sensor pixel clock ↔ display refresh clock) |
| Flow-through Mailbox Register | Bypasses memory array entirely-delivers input data to output in fixed 2-cycle latency for urgent control/command forwarding |
| Write Mask & Read Skip | IE HIGH increments write pointer without writing; OE HIGH increments read pointer without driving outputs-preserves bandwidth during dynamic pipeline reconfiguration |
| DVal Synchronized Output Valid Flag | Removes dependency on REN timing margins-ensures reliable capture of Q[35:0] by downstream logic regardless of REN assertion delay |
| JTAG Boundary Scan Support | Validates solder joint integrity and interconnect routing on dense HDI PCBs without physical probe access |
Applications
| Video Capture Interface | Multi-Stream Display Controller |
|---|---|
Use Scenario: Capturing raw Bayer data from high-resolution CMOS image sensors operating at 120+ MHz pixel clocks. IC Role / Device Role / Timing Role: Frame buffer FIFO bridges sensor pixel clock domain to slower ISP processing clock, absorbing jitter and burst mismatches. Use Value: Prevents frame loss during sensor mode switching by decoupling write bursts from read scheduling-guarantees zero dropped lines under dynamic exposure changes. | Use Scenario: Driving dual independent HDMI displays from a single SoC GPU with mismatched refresh rates (e.g., 60 Hz + 120 Hz). IC Role / Device Role / Timing Role: Dual-port FIFO buffers GPU framebuffer output for each display controller, isolating their timing domains. Use Value: Eliminates visual tearing and stutter by ensuring each display receives continuous, gap-free pixel streams-even during GPU render pipeline stalls. |
| Picture-in-Picture (PiP) Compositor | Industrial Machine Vision Preprocessor |
Use Scenario: Overlaying a smaller secondary video stream (e.g., security feed) onto a primary broadcast stream in real time. IC Role / Device Role / Timing Role: Uses write mask (IE control) to advance write pointer without overwriting main buffer-reserving space for PiP insertion points. Use Value: Enables precise frame-aligned insertion of overlay content without interrupting primary stream continuity or requiring external memory arbitration. | Use Scenario: Buffering high-speed line-scan camera data (100+ MHz) before feeding into FPGA-based real-time defect detection logic. IC Role / Device Role / Timing Role: Absorbs variable latency between camera acquisition and FPGA processing-handles bursty trigger events and pipeline backpressure. Use Value: Guarantees no pixel loss during rapid start/stop imaging sequences, critical for metrology-grade measurement accuracy in automated inspection systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar video frame buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS42S16400F-7TL | SDRAM-based; requires external controller, refresh management, and clock domain crossing logic | Higher latency, lower determinism; suitable only where software-managed buffering suffices | Select only if system already includes SDRAM controller and can tolerate non-FIFO semantics |
| MT48LC4M32B2TG-75 | Legacy SDR SDRAM; 16-bit bus, 75 MHz max; no native dual-clock FIFO logic or EF/FF flags | Lacks hardware flow control and clock-domain isolation-requires custom RTL for safe multi-clock use | Use only in cost-sensitive legacy designs where FPGA resources exist to implement FIFO wrapper logic |
Compared with IS42S16400F-7TL and MT48LC4M32B2TG-75, CYFB0072V18L-133BGXI delivers deterministic latency, hardware-enforced flow control, and zero-software overhead clock-domain bridging-reducing FPGA logic utilization by >35% and eliminating timing closure risks in high-speed video paths.

FAQ
What is the minimum supported clock ratio between RCLK and WCLK?
The device supports RCLK-to-WCLK ratios from 0.5 to 2.0, meaning the slower clock must be no less than half and no more than double the faster clock frequency. This ensures reliable pointer tracking and flag assertion within specified timing margins-verified across –40 °C to +85 °C operation.
How does the flow-through mailbox register interact with normal buffer operation?
When MB is asserted, all normal read/write operations to the 72-Mbit memory array are disabled. Data flows directly from D[35:0] to Q[35:0] with fixed 2-WCLK latency. The mailbox cannot operate concurrently with memory access-designs must complete pending reads (ensuring DVal is high) before asserting MB to avoid data loss.
Can the device retain configuration settings after power cycling?
No-the configuration registers are volatile and reset to default values on power-up or MRS assertion. Retention requires external non-volatile storage and reprogramming via parallel (LD mode) or serial SPI interface during initialization. PRS preserves settings across soft resets but not power loss.
Is JTAG boundary scan supported in functional operation mode?
Yes-JTAG operates independently of normal FIFO operation. TCK/TMS/TDI/TDO pins remain fully functional for boundary scan testing even while RCLK/WCLK are active and data is streaming through the buffer, enabling in-system validation without halting video pipeline operation.
