Product details
Overview
CYF2072V33L-100BGXI from Cypress Semiconductor is a 72-Mbit programmable multi-queue FIFO with independent 36-bit read/write ports, 100-MHz clock operation, LVCMOS 3.3 V I/O support, and configurable ×9–×36 memory organization-designed for high-speed data buffering across asynchronous clock domains in networking and video processing systems.
For engineers reviewing the CYF2072V33L-100BGXI datasheet, CYF2072V33L-100BGXI pinout, CYF2072V33L-100BGXI application, or CYF2072V33L-100BGXI equivalent, key selection considerations include multi-queue configuration (up to 8 queues), mark-and-retransmit capability, flow-through mailbox register, JTAG boundary scan, and industrial temperature range (–40 °C to +85 °C).
Technical Context
The device implements a user-configurable memory array with dual-clock domain operation: write port synchronized to WCLK (up to 100 MHz), read port to RCLK (ratio 0.5–2.0 vs WCLK), and independent pointer control per queue. It supports simultaneous read/write with full flag (FF) synchronized to WCLK and empty flag (EF) to RCLK.
Multi-queue mode is controlled via WQSEL[2:0] and RQSEL[2:0], enabling 2-, 4-, or 8-queue partitioning of the 72-Mbit memory. Queue validity is indicated by QVal[2:0] alongside DVal, and retransmission is triggered by MARK/RT signals to reset the read pointer to a marked physical address.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 72 Mbit total capacity, configurable as single or up to eight independent FIFO queues |
| Max clock frequency | 100 MHz on both WCLK and RCLK, supporting 3.6 Gbps throughput at ×36 bus width |
| I/O voltage standard | LVCMOS 3.3 V (VCCIO = 3.3 V), compatible with 3.3 V logic interfaces and level-shifted systems |
| Bus width options | Selectable ×9, ×12, ×16, ×18, ×20, ×24, ×32, or ×36 via PORTSZ[2:0] pins |
| Operating temperature | –40 °C to +85 °C industrial grade, validated for embedded telecom and industrial control environments |
| Queue count | User-configurable 1, 2, 4, or 8 queues; default 8-queue mode after Master Reset (MRS) |
| Special registers | Flow-through mailbox (MB), serial programming interface (SPI_SCLK/SPI_SI/SPI_SEN), and JTAG TAP controller |
Pinout & Package
Package: 209-ball Fine-Pitch Ball Grid Array (FBGA), 12 mm × 12 mm, 0.8 mm pitch, RoHS-compliant, thermal-enhanced construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D[35:0] | Parallel data input bus | 36-bit wide input path; width reduced per PORTSZ setting (e.g., D[8:0] active in ×9 mode) |
| Q[35:0] | Parallel data output bus | 36-bit output path synchronized to RCLK; outputs tri-stated when OE = HIGH |
| WCLK / RCLK | Independent clock inputs | Asynchronous clocks enable true clock-domain crossing; max ratio 2:1 between WCLK and RCLK |
| WEN / REN / IE / OE | Control enables | WEN/REN gate clocked access; IE enables data latching without pointer increment; OE controls output driver state |
| MARK / RT | Retransmit control | MARK captures current read address; RT resets read pointer to that location for repeat reads |
| MB | Mailbox select | When asserted, bypasses FIFO memory and routes data directly from D[35:0] to Q[35:0] on next read cycle |
| JTAG (TCK/TMS/TDI/TDO) | Boundary scan interface | IEEE 1149.1-compliant test access port for PCB-level interconnect verification |
Key Features
| Feature | Design Value |
|---|---|
| Programmable multi-queue mode | Configurable 1/2/4/8 FIFO queues sharing 72-Mbit memory-enables traffic isolation in packet-switched systems |
| Mark-and-retransmit | Hardware-accelerated re-read from arbitrary FIFO address using MARK/RT pins-critical for protocol retry and error recovery |
| Flow-through mailbox register | Zero-latency direct path from input to output bus-bypasses FIFO storage for urgent control messages or handshaking |
| Serial configuration interface | SPI-compatible (SPI_SCLK/SPI_SI/SPI_SEN) for runtime register programming without halting main data flow |
| JTAG boundary scan | Fully compliant IEEE 1149.1 TAP controller integrated-supports automated PCB test and debug in production |
Applications
| Network Packet Buffering | Video Frame Synchronization |
|---|---|
|
Use Scenario: High-speed Ethernet switch ASIC buffers ingress/egress packets across PHY-to-MAC clock domains. IC Role / Device Role / Timing Role: Dual-port FIFO with independent WCLK/RCLK domains absorbs jitter and rate mismatches between 10G PHY and packet processor. Use Value: 72-Mbit depth supports >1 ms buffering at 10 Gbps; 8-queue mode isolates priority traffic classes (e.g., control vs. data queues). |
Use Scenario: HDMI transmitter IC synchronizes pixel data streams from GPU (297 MHz) to display timing controller (74.25 MHz). IC Role / Device Role / Timing Role: Clock-domain crossing buffer with flow-through mailbox for embedded sync signals (e.g., VSYNC/HSYNC). Use Value: ×36 bus width matches RGB888+control bus; DVal/QVal signals enable precise frame boundary tracking across clocks. |
| Industrial PLC Data Acquisition | Medical Imaging Pipeline |
|
Use Scenario: Multi-sensor DAQ system aggregates analog-to-digital samples from 16 channels at 1 MSPS into a central FPGA. IC Role / Device Role / Timing Role: Multi-queue FIFO assigns one queue per sensor channel; MARK/RT enables retransmission of corrupted frames. Use Value: Industrial temp rating (–40 °C to +85 °C) ensures reliability in factory-floor enclosures; JTAG simplifies field diagnostics. |
Use Scenario: MRI subsystem buffers real-time k-space data from ADCs before FFT processing in FPGA-based reconstruction engine. IC Role / Device Role / Timing Role: High-throughput FIFO with 100-MHz clocks handles 2.4 Gbps raw ADC stream (16-bit × 150 MSPS). Use Value: 72-Mbit depth accommodates full k-space matrix (e.g., 1024 × 1024 × 16-bit); MB register forwards trigger metadata without latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable FIFO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT72V2115L10PF | 36-Mbit density, ×18/×36 only, no multi-queue or mailbox; 100 MHz, 3.3 V | Limited to single-queue buffering; lacks MARK/RT and JTAG | Choose for cost-sensitive, single-stream applications where queue isolation is unnecessary |
| ON Semiconductor NB3N502FG | Not a FIFO-dual PLL clock generator with jitter cleaning; no memory or queuing | Replaces clock synchronization, not data buffering; incompatible function | Reject as functional non-equivalent; only consider if system requires clock generation instead of buffering |
Compared with IDT72V2115L10PF and NB3N502FG, CYF2072V33L-100BGXI uniquely delivers scalable multi-queue architecture, hardware retransmit, and mailbox bypass-making it the sole fit for systems requiring concurrent, isolated, and recoverable data streams across clock domains.

FAQ
What is the maximum supported clock frequency for CYF2072V33L-100BGXI?
The device supports up to 100 MHz on both WCLK and RCLK inputs. This is specified under AC switching characteristics in the datasheet (Document 001-68336 Rev. *J, page 19). Operation above 100 MHz violates timing margins and may cause metastability or data corruption in pointer logic.
Does CYF2072V33L-100BGXI support 1.8 V I/O voltage?
No-CYF2072V33L-100BGXI is the 3.3 V I/O variant (denoted by "33" in the part number). The "V33L" suffix confirms VCCIO = 3.3 V. For 1.8 V operation, the correct part is CYF2072V18L-100BGXI, which uses separate VCCIO = 1.8 V and VCC1/VCC2 = 1.8 V rails.
How many queues can be simultaneously active?
All eight queues are physically implemented and can be accessed concurrently via WQSEL[2:0] and RQSEL[2:0]. However, only one queue is written to per WCLK edge and one read from per RCLK edge. Full parallelism requires external arbitration logic-no internal cross-queue arbitration is provided.
Is JTAG boundary scan mandatory for operation?
No-JTAG is optional and disabled by default. TCK/TMS/TDI/TDO pins are unused during normal FIFO operation and may be left unconnected or tied to VSS. Boundary scan functionality activates only when TAP controller enters Test-Logic-Reset or Run-Test/Idle states per IEEE 1149.1.
