Product details
Overview
CY7C0832AV-133AXI from Infineon Technologies is a 256K × 18-bit synchronous dual-port SRAM with 3.3 V core/interface supply, 133 MHz maximum clock frequency, and pipelined read/write operation supporting concurrent access on independent ports. It implements true dual-port architecture with separate address/data/control buses per port, enabling real-time data buffering in network packet processors and telecom line cards.
For engineers reviewing the CY7C0832AV-133AXI datasheet, CY7C0832AV-133AXI pinout, CY7C0832AV-133AXI application, or CY7C0832AV-133AXI equivalent, key selection criteria include simultaneous read/write latency (1-cycle pipeline), 3.3 V I/O compatibility, industrial temperature range (–40°C to +85°C), and QFP-100 package footprint for high-density PCB layout.
Technical Context
This device belongs to Infineon's Cypress-branded synchronous dual-port SRAM family, designed for deterministic low-latency memory access in systems requiring two independent bus masters-such as DSP + microcontroller co-processing or FPGA + ASIC interconnect. Its pipelined architecture delivers one-word-per-clock throughput on both ports without arbitration overhead.
The CY7C0832AV-133AXI supports byte-wide write masking (UB/LB controls), programmable output drive strength (12/24 mA), and JTAG boundary-scan (IEEE 1149.1) for production testability. All control signals are registered on rising CLK edges, ensuring precise timing alignment across voltage and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256K × 18 bits = 4.5 Mbit total; supports 18-bit parallel data paths for wide-bus applications like video frame buffers. |
| Max Clock Frequency | 133 MHz; enables 133 million words/sec sustained throughput per port under pipelined operation. |
| Access Time | 6.5 ns (tAA); guaranteed minimum cycle time for first-word read after address setup, critical for real-time interrupt response. |
| Supply Voltage | 3.3 V ± 0.3 V core and I/O; eliminates level-shifting requirements when interfacing with 3.3 V FPGAs or microcontrollers. |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade deployment in base station equipment and motor control drives. |
| Package | 100-pin TQFP (14 mm × 14 mm, 0.5 mm pitch); compatible with standard reflow profiles and automated optical inspection. |
| Write Cycle Time | 7.5 ns (tCW); defines minimum time between consecutive write operations on same port, constraining burst write bandwidth. |
Pinout & Package
Package: 100-pin Thin Quad Flat Package (TQFP), lead-free and RoHS-compliant, with exposed thermal pad for enhanced heat dissipation in continuous high-speed operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKA / CLKB | Port A/B clock input | Rising-edge-triggered synchronous interface; both clocks operate independently, enabling asymmetric timing domains. |
| ADDA[17:0] / ADDB[17:0] | Port A/B address bus | 18-bit address lines support full 256K-word addressing; no external address latching required. |
| DATAA[17:0] / DATAB[17:0] | Port A/B bidirectional data bus | 18-bit parallel I/O; supports byte-select writes via UBA/LBA pins for partial-word updates without read-modify-write. |
| CEA / CEB | Port A/B chip enable | Active-low enables; allows port-level power gating and selective port disable during idle cycles. |
| WEA / WEB | Port A/B write enable | Controls direction of data bus; deassertion configures port as read-only for safe concurrent access. |
| OE | Output enable | Global tri-state control for all data outputs; synchronizes with clock to prevent bus contention glitches. |
| VDDQ / VSSQ | I/O power/ground | Separate 3.3 V I/O rail decoupling improves signal integrity and reduces switching noise coupling into core logic. |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined read/write | One-cycle latency per word after initial setup; eliminates wait states in streaming data applications like packet buffering. |
| Independent port arbitration | No internal bus contention-ports operate fully concurrently, enabling lock-free producer-consumer FIFO implementation. |
| JTAG boundary-scan | IEEE 1149.1 compliant; supports automated PCB test and in-system verification without dedicated test pads. |
| Programmable drive strength | Selectable 12 mA or 24 mA output drive; optimizes signal rise/fall times for varying trace lengths and loading conditions. |
| Byte write control | UBA/LBA and UBB/LBB pins enable 9-bit granularity writes; avoids destructive full-word updates in mixed-data-size systems. |

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 |
|---|---|---|---|
| IDT70V27L15PF8 | 15 ns access time, 100-pin PQFP, 3.3 V only, no JTAG support | Lacks boundary-scan; requires external test fixtures for production validation | Preferred where JTAG is unnecessary and lower cost is prioritized over testability |
| ISSI IS61WV25618BLL-133TQLI | Same 256K×18 density and 133 MHz speed, but uses 100-pin TQFP with different pinout (non-pin-compatible) | Requires PCB redesign due to address/data pin remapping and missing OE pin | Consider only for new designs where layout flexibility exists and second-source assurance is critical |
Compared with IDT70V27L15PF8 and IS61WV25618BLL-133TQLI, the CY7C0832AV-133AXI provides integrated JTAG testability and guaranteed 6.5 ns tAA-enabling tighter timing margins in high-speed control loops without external logic.

FAQ
What is the maximum supported clock frequency for CY7C0832AV-133AXI?
The CY7C0832AV-133AXI is rated for a maximum clock frequency of 133 MHz on both ports, validated across the full industrial temperature range (–40°C to +85°C) and 3.3 V ±0.3 V supply. This rating assumes proper PCB layout with matched trace lengths and adequate power rail decoupling per the manufacturer's layout guidelines.
Does CY7C0832AV-133AXI support asynchronous operation?
No. The CY7C0832AV-133AXI is strictly a synchronous dual-port SRAM: all address, data, and control signals are sampled on the rising edge of the respective port clock (CLKA/CLKB). There is no asynchronous mode or transparent latch behavior-the device requires clocked operation for all read and write cycles.
Can Port A and Port B operate at different clock frequencies?
Yes. The CY7C0832AV-133AXI allows independent clocking of Port A and Port B, enabling heterogeneous system integration-for example, connecting Port A to a 100 MHz FPGA fabric and Port B to a 133 MHz DSP core. Timing isolation between ports is maintained by separate clock trees and no internal synchronization logic.
Is the CY7C0832AV-133AXI pin-compatible with earlier CY7C0832AV-15BCXI variants?
No. While both share the same 100-pin TQFP package, the CY7C0832AV-133AXI has a revised pinout including relocated VDDQ/VSSQ pins and added JTAG signals (TCK/TMS/TDI/TDO), making it incompatible with PCBs designed for the -15BCXI version without hardware modification.
