Product details
Overview
CYD09S36V18-200BBXI from Cypress Semiconductor is a 9-Mbit (256K × 36) synchronous true dual-port SRAM with independent 36-bit ports, 1.8 V/1.5 V core supply, and 200 MHz SDR interface supporting up to 14.4 Gbps aggregate bandwidth. It implements deterministic access control for simultaneous port contention, built-in mailbox with interrupt flags, and burst counter logic-used in high-speed packet buffering and FPGA co-processor memory interfaces.
For engineers reviewing the CYD09S36V18-200BBXI datasheet, CYD09S36V18-200BBXI pinout, CYD09S36V18-200BBXI application, or CYD09S36V18-200BBXI equivalent, key selection criteria include pipelined vs. flow-through latency mode, per-port I/O voltage flexibility (1.8 V LVCMOS/2.5 V LVCMOS), echo clock support, and collision-handling flag behavior on back-to-back address conflicts.
Technical Context
This device belongs to the FullFlex36 family and uses synchronous dual-port architecture with two independent clock domains (CLKL/CLKR), each supporting single-data-rate operation at up to 200 MHz. Address collision detection triggers deterministic flag assertion and first-busy-address readback within one cycle.
Each port features selectable pipelined (2-cycle read latency) or flow-through (1-cycle read latency) timing, configurable byte enables (BE[3:0]), and independent I/O standards-including 1.8 V LVCMOS, 2.5 V LVCMOS, or LVTTL-with variable impedance matching (VIM) enabled via ZQ pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 9 Mbit (256K × 36 bits), enabling compact dual-port buffer for 36-bit data paths |

| Per-port I/O voltage selectability | Enables direct connection to 1.8 V FPGA banks or 2.5 V ASIC I/O without level shifters |
| Burst counter with mirror register | Reduces address bus traffic during sequential accesses; retransmit function reloads counter from mirrored start address |
| Mailbox with interrupt flags | Supports lock-free inter-processor communication between CPU and DSP/FPGA using shared memory regions |
| Echo clock outputs (CQ0/CQ1) | Delivers phase-aligned clock copies to simplify source-synchronous capture timing at receiving logic |
Applications
| Telecom Line Card Buffering | FPGA-Based Protocol Analyzer |
|---|---|
Use Scenario: Storing incoming/outgoing ATM or Ethernet frames in carrier-grade line cards where ingress and egress paths operate independently. IC Role / Device Role / Timing Role: Dual-port SRAM acts as non-blocking frame buffer-left port accepts data from PHY, right port feeds switch fabric-both at full 200 MHz rate. Use Value: Deterministic collision handling ensures no frame loss during bursty traffic peaks; echo clocks align capture timing across multi-FPGA architectures. | Use Scenario: Capturing and post-processing high-speed serial protocol traffic (e.g., PCIe, SATA) using FPGA-based logic analyzers with deep trace memory. IC Role / Device Role / Timing Role: Left port stores captured data under FPGA control; right port streams data to host processor via DMA-no software intervention required during capture. Use Value: Mailbox interrupts notify host when buffer is half-full; burst counter automates address incrementing, reducing FPGA logic resource usage by >12%. |
| Industrial Motion Controller | Avionics Data Concentrator |
Use Scenario: Real-time coordination of multiple servo axes in CNC machines, requiring synchronized position/velocity updates between motion CPU and FPGA trajectory engine. IC Role / Device Role / Timing Role: Shared memory space for coordinate tables and status registers-CPU writes setpoints, FPGA reads and executes interpolation in hard real-time loop. Use Value: Flow-through read mode achieves 5 ns read latency; deterministic busy flag prevents overwrites during concurrent access-meeting <1 µs jitter requirement. | Use Scenario: Aggregating ARINC 429, MIL-STD-1553, and discrete I/O data from multiple avionics subsystems into a centralized health monitoring unit. IC Role / Device Role / Timing Role: Left port receives time-stamped sensor packets from interface ASICs; right port supplies consolidated reports to flight management computer. Use Value: Independent I/O voltage settings allow 1.8 V connection to ARINC receiver ASICs and 2.5 V link to legacy 1553 transceivers-reducing board-level voltage conversion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV102436BLL-15BLI | 1024K × 36, 15 ns async access; no pipelined mode, no mailbox or burst counter | Lacks deterministic collision handling and echo clocks-requires external arbitration logic for real-time systems | Choose only if system clock ≤100 MHz and latency tolerance >15 ns; not suitable for 200 MHz SDR timing closure |
| SN74ALVC164245DGGR | Level-shifting transceiver-not memory; no storage, no dual ports, no clock domain isolation | Cannot replace SRAM functionality; only useful for voltage translation between buses | Not a functional alternative; included only to clarify common mis-selection error in mixed-voltage designs |

FAQ
What is the maximum supported I/O voltage for CYD09S36V18-200BBXI?
The device supports 1.8 V LVCMOS, 2.5 V LVCMOS, and LVTTL I/O standards per port-configurable independently via the CONFIG block. Core voltage remains fixed at 1.5 V or 1.8 V. No 3.3 V I/O is supported; attempting to exceed 2.5 V on VDDIO may damage the device.
Does CYD09S36V18-200BBXI support JTAG boundary scan?
Yes, it implements IEEE 1149.1 JTAG boundary scan with TDI, TDO, TMS, TCK, and TRST pins. Scan chain includes all I/O buffers and internal control logic. Boundary scan testing is fully supported per the 38-06082 Rev. *S specification and requires no special configuration mode.
How does the deterministic access control resolve simultaneous port conflicts?
When both ports access the same address on the same clock edge, the device asserts BUSY and FLAG outputs within one cycle and places the contending address on the address bus for readback. The left port wins arbitration; the right port receives a delayed response. This behavior is guaranteed across temperature and voltage ranges per datasheet timing diagrams.
Can CYD09S36V18-200BBXI be used in industrial temperature applications?
Yes, the -200BBXI suffix denotes Industrial temperature grade (–40 °C to +85 °C). All electrical characteristics-including 200 MHz operation, setup/hold times, and VIM calibration-are specified and tested across this range. Thermal resistance (θJA = 32 °C/W) ensures reliable operation under typical PCB layouts with 2 oz copper and 4 thermal vias.
