Product details
Overview
CY7C1480V33-167BZI from Cypress Semiconductor is a 72-Mbit pipelined synchronous SRAM configured as 2M × 36, operating at 167 MHz with 3.3V core and 2.5V/3.3V I/O supply, registered inputs/outputs for burst-mode timing, and JTAG-compliant boundary scan - deployed in high-speed CPU cache subsystems requiring deterministic 3.4 ns clock-to-output access.
For engineers reviewing the CY7C1480V33-167BZI datasheet, CY7C1480V33-167BZI pinout, CY7C1480V33-167BZI application, or CY7C1480V33-167BZI equivalent, key selection factors include synchronous burst control (ADSP/ADSC/ADV), byte-write granularity (BWA–BWD + BWE), ZZ sleep mode support, and JEDEC-standard 100-pin TQFP packaging with VDDQ/VSSQ separation for I/O noise immunity.
Technical Context
This SRAM implements a two-bit synchronous wraparound burst counter, user-selectable via MODE pin to generate either Intel Pentium®-compatible interleaved or linear burst sequences. All address, data, and control inputs (except OE and ZZ) are registered on the rising edge of CLK, enabling precise pipelined timing across multi-cycle read/write operations.
Write cycles are self-timed and support single-cycle chip deselect, asynchronous output enable (OE), and global write override (GW). The device integrates separate processor (ADSP) and controller (ADSC) address strobes, allowing flexible integration into dual-bus architectures while maintaining strict tCO ≤ 3.4 ns and tAA ≤ 3.4 ns at 167 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 72 Mbit (2M × 36 organization), directly supporting L2 cache line widths for x86-compatible processors. |
| Max Clock Frequency | 167 MHz - defines maximum sustained burst throughput of 600 MB/s (36-bit bus × 167 MHz). |
| Access Time (tCO) | 3.4 ns - guaranteed clock-to-output delay under worst-case 167 MHz operation, critical for timing closure in synchronous bus designs. |
| Core Supply | 3.3V ± 0.3V - powers internal logic and memory array; requires dedicated low-noise regulation per Cypress design guidelines. |
| I/O Supply Range | 2.5V or 3.3V - supports mixed-voltage system interfacing without level shifters when VDDQ = VDD or VDDQ = 2.5V. |
| Burst Mode Control | Intel Pentium®-interleaved or linear via MODE pin - enables drop-in compatibility with legacy and modern processor burst protocols. |
| Byte Write Support | Four independent byte lanes (BWA–BWD) qualified by BWE - allows partial-word writes without read-modify-write overhead. |
Pinout & Package
Package: 100-pin TQFP (14 × 14 mm, 0.5 mm pitch), lead-free compliant, JEDEC-standard footprint with exposed thermal pad (not electrically connected).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A[2:19] | Synchronous Address Input | 21-bit address bus sampled on CLK rise when ADSP/ADSC active; A1:A0 load burst counter for sequential access. |
| BWA–BWD, BWE | Synchronous Byte Write Control | Active-low per-byte write enables; BWE must be LOW to activate any BWX signal - enables 1–4 byte granularity writes. |
| GW | Synchronous Global Write Enable | Active-low override that forces write to all 36 bits regardless of BWX states - eliminates need for full-word masking logic. |
| ADSP / ADSC | Synchronous Address Strobe | Processor- or controller-originated strobe; selects source of address capture and determines priority in concurrent assertion. |
| ADV | Synchronous Burst Advance | Active-low signal that increments internal burst counter on CLK rise - enables fully pipelined burst reads/writes without external sequencing. |
| ZZ | Asynchronous Sleep Input | Active-high entry into low-power sleep mode (ISB ≤ 120 mA); retains data; internal pull-down allows floating for normal operation. |
| DQPA–DQPD | Synchronous Bidirectional Data | 36-bit data bus (four 9-bit groups); direction controlled by OE; outputs registered on CLK rise for jitter-immune timing. |
| VDDQ / VSSQ | I/O Power / Ground | Separate 2.5V/3.3V I/O rail with dedicated ground - isolates switching noise from core logic, improving signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined synchronous interface | Full register-to-register timing path with CLK-synchronized address/data/control - eliminates external latch requirements and simplifies PCB layout. |
| User-selectable burst sequence | MODE pin configures interleaved (Pentium®) or linear burst order - enables reuse across multiple processor generations without firmware change. |
| Self-timed write cycle | On-chip write timing logic eliminates need for external write-strobe generation or wait-state insertion - reduces controller complexity. |
| Single-cycle chip deselect | CE1/CE2/CE3 deassertion on CLK rise immediately disables output drivers and halts internal access - prevents bus contention during bank switching. |
| JTAG boundary scan (IEEE 1149.1) | Fully compliant test access port with TDI/TDO/TCK/TMS pins - enables in-system verification of interconnect integrity without physical probe access. |
Applications
| High-Performance CPU Cache | Network Packet Buffer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous burst SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS7C3256A-15JC | 256K × 36, 15 ns async access, no burst counter or ADSP/ADSC interface - purely asynchronous interface. | Lacks pipelined timing and burst control; suitable only for non-critical control-plane buffers where clock alignment is unnecessary. | Select only if system lacks synchronous clock domain or requires <100 MHz operation with minimal timing analysis. |
| IS61WV102432BLL-10TLI | 1M × 32, 10 ns async access, no ZZ sleep, no JTAG, no byte-write enable granularity - 32-bit bus, no BWA–BWD. | Lower density and fixed 32-bit width limits use in 36-bit cache lines; no power-gating capability restricts battery-powered radar use. | Choose only for cost-sensitive, non-bursting applications where 32-bit width and absence of sleep mode are acceptable. |
Compared with AS7C3256A-15JC and IS61WV102432BLL-10TLI, CY7C1480V33-167BZI uniquely delivers pipelined burst timing, processor-aligned strobe protocol (ADSP/ADV), and hardware sleep control - making it irreplaceable in deterministic cache and real-time signal buffering where timing predictability and power-aware operation are mandatory.

FAQ
What is the function of the MODE pin on CY7C1480V33-167BZI?
The MODE pin selects the burst sequence type: logic HIGH configures Intel Pentium®-compatible interleaved addressing (0,2,4,6,1,3,5,7), while logic LOW enables linear addressing (0,1,2,3,4,5,6,7). It is sampled once at power-up or reset and remains latched until next reset - no runtime reconfiguration is supported.
Can CY7C1480V33-167BZI operate with VDDQ = 2.5V while VDD = 3.3V?
Yes - the device supports mixed I/O voltage operation: VDD must be 3.3V ± 0.3V for core logic, while VDDQ may be independently set to either 2.5V ± 0.2V or 3.3V ± 0.3V. This allows direct interfacing to 2.5V FPGAs or ASICs without external level shifters, provided VSSQ is tied to the same ground as VSS.
How does the ZZ sleep mode affect data retention and wake-up time?
In ZZ sleep mode (ZZ = HIGH), core current drops to ≤120 mA standby, but all stored data is retained indefinitely at temperatures from –40°C to +85°C. Wake-up is asynchronous: asserting ZZ = LOW restores full operation within one CLK cycle - no additional stabilization delay is required before issuing ADSP or ADSC.
Is the 100-pin TQFP package of CY7C1480V33-167BZI RoHS-compliant?
Yes - the -167BZI suffix denotes a lead-free, RoHS-compliant 100-pin TQFP package meeting JEDEC standard J-STD-020 moisture sensitivity level 3 (MSL3), with peak reflow temperature of 260°C. The package uses matte tin finish and contains no intentionally added lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE.
