Product details
Overview
CY7C1460AV33-167AXI from Cypress Semiconductor is a 3.3V, 36 Mbit (1M × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput back-to-back read/write operations in networking and telecom data paths. It delivers 167 MHz bus operation with zero wait states, 3.4 ns maximum access time, and supports byte-write control via BWa–BWd pins. Used in packet buffering and cache coherency modules where deterministic latency and burst throughput are critical.
For engineers reviewing the CY7C1460AV33-167AXI datasheet, CY7C1460AV33-167AXI pinout, CY7C1460AV33-167AXI application, or CY7C1460AV33-167AXI equivalent, this page provides verified timing parameters, JEDEC-compliant TQFP/165-ball FBGA package mapping, synchronous self-timed write behavior, and functional equivalence to ZBT SRAMs - all essential for memory subsystem validation and migration planning.
Technical Context
The device implements fully registered pipelined I/O: all address, control, and data inputs pass through input registers on CLK rising edge; all outputs are clocked through output registers synchronized to the same edge. Its NoBL™ logic eliminates bus latency by enabling consecutive read/write cycles without inter-cycle gaps.
It supports linear or interleaved burst addressing (controlled by MODE pin), synchronous self-timed writes qualified by WE and BWa–BWd, and tristate control via asynchronous OE - with automatic output disable during write data phases to prevent bus contention. Clock Enable (CEN) suspends clock recognition without deselecting the device.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 36 Mbit (1,048,576 × 36 bits) - supports full-word parallel data transfers in 36-bit wide systems. |
| Max Clock Frequency | 167 MHz - enables sustained 167 MT/s throughput with no wait states in pipelined mode. |
| Access Time | 3.4 ns - defines worst-case clock-to-output delay under 167 MHz operation, critical for setup/hold timing closure. |
| Supply Voltage | VDD = 3.135–3.6 V; VDDQ = 3.135–3.6 V or 2.3–2.7 V - allows mixed-voltage I/O interfacing with 2.5V or 3.3V logic families. |
| Byte Write Capability | BWa–BWd (active-low) control four independent 9-bit byte lanes - enables partial-word writes without read-modify-write overhead. |
| Power Consumption | 375 mA max operating current; 120 mA max CMOS standby current - defines thermal budget and power rail sizing for dense memory arrays. |
| Package Options | 100-pin TQFP (JEDEC MS-026) and 165-ball FBGA (15 × 17 mm, 0.8 mm pitch) - both Pb-free compliant and validated for industrial temperature range (–40°C to +85°C). |
Pinout & Package
Available in 100-pin TQFP (JEDEC MO-145) and 165-ball FBGA (15 × 17 mm, 0.8 mm pitch). Both packages support industrial temperature range (–40°C to +85°C) and Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Synchronous Address Inputs | Sampled on rising CLK edge; select one of 1M addresses (A0–A19 required for 1M × 36 configuration). |
| BWa–BWd | Synchronous Byte Write Selects | Active-low controls 9-bit byte lanes (DQa/DQPa, DQb/DQPb, DQc/DQPc, DQd/DQPd); qualified by WE. |
| CLK | Primary Clock Input | Rising-edge-triggered master clock; gated by CEN; drives all internal registers and burst logic. |
| CEN | Clock Enable | Active-low; masks CLK without deselecting device - extends previous cycle for timing margin or power gating. |
| CE1, CE3 | Synchronous Chip Enables | Active-low; sampled on CLK rise; used with CE2 (active-high) for multi-chip bank selection. |
| OE | Asynchronous Output Enable | Active-low; overrides synchronous logic to tristate outputs - masked during write data phase to avoid contention. |
| DQa–DQd, DQPa–DQPd | Bidirectional Data I/O | 36-bit data bus (4 × 9-bit bytes); direction controlled by OE and internal state; registered I/O ensures timing predictability. |
| ADV/LD | Advance/Load Control | High advances internal burst counter; low loads new address - enables seamless burst sequencing or random access initiation. |
Key Features
| Feature | Design Value |
|---|---|
| No Bus Latency™ Architecture | Enables true back-to-back read/write operations with zero wait states - eliminates pipeline bubbles in high-speed data streaming applications. |
| Fully Registered Pipelined I/O | All inputs and outputs clocked on CLK rising edge - guarantees deterministic timing and simplifies PCB layout with uniform clock skew management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous pipelined SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT72V2115L16PF | 2.5V-only VDDQ supply; 165-ball FBGA only; 167 MHz max, but requires external OE timing control. | Lacks NoBL™ architecture - introduces 1-cycle latency between read/write transitions. | Choose when 2.5V I/O compatibility is mandatory and burst depth is shallow (≤4 words). |
| ISSI IS61WV102436B | 3.3V VDD/VDDQ; 100-pin TQFP only; 167 MHz, but no JTAG boundary scan or ZZ sleep mode. | Missing ADV/LD and MODE pins - supports linear burst only, no interleaved addressing. | Choose for cost-sensitive designs where JTAG testability and dual-burst modes are not required. |
Compared with IDT72V2115L16PF and IS61WV102436B, CY7C1460AV33-167AXI uniquely combines NoBL™ zero-latency pipelining, dual-burst addressing, JTAG testability, and flexible 2.5V/3.3V I/O - making it optimal for high-reliability telecom and industrial systems demanding full feature parity with legacy ZBT designs.

FAQ
What is the function of the MODE pin on CY7C1460AV33-167AXI?
The MODE pin selects burst addressing order: tied to GND enables linear burst (sequential increment), while floating or connected to VDD enables interleaved burst (bit-swapped increment). This matches legacy ZBT controller expectations and is sampled at power-up or reset - not dynamically changeable during operation.
Does CY7C1460AV33-167AXI support true dual-port operation?
No - it is a single-port synchronous SRAM with pipelined read/write capability. While it supports back-to-back reads and writes without wait states, it cannot perform simultaneous read and write to different addresses. True dual-port functionality requires separate address/data buses and independent clocks, which this device does not implement.
Can the ZZ (Sleep) pin be used to reduce power during idle periods?
Yes - asserting ZZ LOW places the device in low-power sleep mode, reducing ICC to ≤5 mA. Unlike CEN, ZZ disables internal clocks and memory array biasing. Recovery time is 20 ns, and the device retains data. This is distinct from CEN, which only gates CLK but maintains full readiness.
Is the 165-ball FBGA package of CY7C1460AV33-167AXI compatible with standard reflow profiles?
Yes - the 165-ball FBGA (15 × 17 mm, 0.8 mm pitch) is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles (peak 260°C, 60-second duration above 217°C). Board layout must follow Cypress's recommended pad stack and stencil aperture guidelines to ensure solder joint reliability.
