Product details
Overview
CY7C1480V33-167AXC from Cypress Semiconductor is a 72-Mbit pipelined synchronous SRAM organized as 2M × 36, operating at 167 MHz with 3.3 V core supply and 2.5/3.3 V I/O compatibility. It features registered inputs/outputs, synchronous self-timed writes, and user-selectable Intel Pentium®-compatible interleaved or linear burst sequences. Used in high-speed secondary cache subsystems for embedded processors requiring deterministic low-latency memory access.
For engineers reviewing the CY7C1480V33-167AXC datasheet, CY7C1480V33-167AXC pinout, CY7C1480V33-167AXC application, or CY7C1480V33-167AXC equivalent, this page delivers verified timing parameters, JEDEC-compliant TQFP package details, burst control logic behavior, byte-write architecture, and validated alternatives for cache memory design.
Technical Context
The device implements a 2-bit synchronous wraparound burst counter controlled by ADV, ADSP, and ADSC signals, with address latching on CLK rising edge only when CE1 (active LOW), CE2 (active HIGH), and CE3 (active LOW) are simultaneously asserted. MODE pin selects between interleaved and linear burst addressing at power-up or reset.
All data inputs and write controls (BWA–BWD, BWE, GW) are registered on CLK rising edge; outputs are registered and driven with 3.4 ns clock-to-output delay (tCO) at 167 MHz. OE is asynchronous and masks output enable during first read cycle after chip deselect.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 72 Mbit (2M × 36 configuration) |
| Max Clock Frequency | 167 MHz - defines maximum sustained burst throughput of 600 MB/s (36-bit bus) |
| Access Time (tCO) | 3.4 ns - guaranteed clock-to-output delay for synchronous reads at 167 MHz |
| Core Supply Voltage | 3.3 V ± 0.3 V - powers internal SRAM array and registers; not tolerant of 2.5 V core operation |
| I/O Supply Range | 2.5 V or 3.3 V - supports mixed-voltage system interfacing with processor or controller I/O domains |
| Burst Mode Control | User-selectable via MODE pin - enables either Pentium®-interleaved (A0,A1) or linear address sequencing |
| Write Architecture | Synchronous self-timed writes with byte-select (BWA–BWD) and global write (GW) override |
Pinout & Package
Package: JEDEC-standard Pb-free 100-pin thin quad flat pack (TQFP), 14 × 20 × 1.4 mm, with separate VDDQ/VSSQ pins for I/O power integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock input | Positive-edge-triggered master clock synchronizing all registered inputs, outputs, and burst counter |
| ADSP / ADSC | Address strobe (processor/controller) | Edge-sensitive enable for address capture; ADSP takes priority when both asserted |
| ADV | Burst advance control | Active-LOW signal that increments internal 2-bit burst counter on next CLK edge |
| CE1, CE2, CE3 | Chip enable group | Three-level synchronous selection: CE1 (LOW), CE2 (HIGH), CE3 (LOW) required for valid access |
| BWA–BWD | Byte write select | Four active-LOW signals enabling independent 9-bit writes to DQA–DQD banks |
| GW | Global write enable | Active-LOW override that forces full 36-bit write regardless of BWA–BWD states |
| OE | Asynchronous output enable | Tri-states DQ/DQP pins immediately when HIGH; masked during first read after deselect |
| ZZ | Asynchronous sleep mode | Active-HIGH entry into low-power state preserving data; internal pull-down ensures safe default LOW |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined synchronous interface | Full register-to-register timing with 3.4 ns tCO enables tight integration with 167 MHz CPU buses without wait states |
| User-selectable burst sequence | MODE pin configures interleaved (Pentium®) or linear addressing - eliminates need for external address translation logic |
| Byte-write granularity | Four independent 9-bit write lanes (DQA–DQD) controlled by BWA–BWD + BWE allow partial-word updates without read-modify-write cycles |
| JEDEC JESD8-5 I/O compliance | Ensures interoperability with 2.5 V and 3.3 V logic families while maintaining signal integrity across wide temperature range |
| IEEE 1149.1 boundary scan | Integrated JTAG TAP controller supports production test and board-level diagnostics without additional hardware |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous burst SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV102436BLL-167TQLI | 1024K × 36 organization, same 167 MHz speed grade, but uses single 3.3 V supply (no VDDQ/VSSQ separation) | Lacks separate I/O voltage domain - unsuitable for mixed 2.5 V/3.3 V systems requiring level-shifting isolation | Select when system uses uniform 3.3 V I/O and requires lower pin count (86-pin TSOP-II vs. 100-pin TQFP) |
| AS7C3256B-167JCIN | 256K × 36 density, 167 MHz, 3.3 V core/I/O, no ZZ sleep mode or JTAG support | Lower density and missing sleep/JTAG limits use in power-constrained or test-critical applications | Select for cost-sensitive designs where 72 Mbit capacity is excessive and debug/test coverage is non-critical |
Compared with IS61WV102436BLL-167TQLI and AS7C3256B-167JCIN, CY7C1480V33-167AXC uniquely supports dual I/O voltage domains, asynchronous sleep (ZZ), and IEEE 1149.1 boundary scan - making it the only choice for high-reliability, mixed-voltage, test-ready cache implementations.

FAQ
What is the function of the MODE pin on CY7C1480V33-167AXC?
The MODE pin selects the burst address sequence at power-up or reset: LOW configures linear burst ordering (sequential A0–A1 increment), while HIGH enables Intel Pentium®-compatible interleaved addressing (A0,A1 bit-swapped pattern). This setting is latched internally and remains fixed until next power cycle or hardware reset - no runtime reconfiguration is supported.
Can CY7C1480V33-167AXC operate with only a 2.5 V supply?
No. The device requires a dedicated 3.3 V ± 0.3 V core supply (VDD) for the SRAM array and registers. However, its I/O circuitry accepts either 2.5 V or 3.3 V on VDDQ, allowing direct interface with 2.5 V processors while maintaining full 3.3 V core functionality and timing specifications.
How does the ZZ (sleep) mode affect power consumption and data retention?
In ZZ mode (pin driven HIGH), core current drops to ≤120 mA standby, matching the CMOS standby spec. Data integrity is fully preserved - no refresh or backup power is needed. The device exits sleep synchronously on next CLK edge after ZZ returns LOW, with no additional latency beyond standard access timing.
Is the CY7C1480V33-167AXC pin-compatible with CY7C1482V33-167AXC?
No. CY7C1480V33-167AXC (2M × 36) and CY7C1482V33-167AXC (4M × 18) differ in memory organization, pin assignment (e.g., address bit count, DQP placement), and FBGA ballout - they share functional similarity but are not mechanically or electrically interchangeable. TQFP packages are distinct and non-mappable.
