Product details
Overview
CY7C1367A-150AJC from Cypress Semiconductor is a 512K × 18-bit synchronous pipelined SRAM with 150 MHz clock speed, 3.5 ns access time, and 3.3 V core supply. It features byte write enable (BWa/BWb), burst control (ADSC/ADSP/ADV), and asynchronous OE for high-speed memory interfacing in networking line cards and telecom data buffers.
For engineers reviewing the CY7C1367A-150AJC datasheet, CY7C1367A-150AJC pinout, CY7C1367A-150AJC application, or CY7C1367A-150AJC equivalent, key selection criteria include burst mode support (linear/interleaved), dual chip enable (CE1/CE2), JTAG boundary scan capability, and compatibility with LVTTL/LVCMOS I/O at 3.3 V or 2.5 V.
Technical Context
This SRAM implements a synchronous, clocked architecture where all address, data, and control inputs (except OE and MODE) are registered on the rising edge of CLK. Internal address pipelining uses ADSC/ADSP to initiate reads and ADV to control burst counter advancement during linear or interleaved sequences.
The device supports depth expansion via CE1 (active-low) and CE2 (active-high), with no CE3 in the T/AJ package. Byte-level writes are enabled by BWa/BWb (x18 configuration), while GW enables full 18-bit writes; OE remains asynchronous for output enable timing independence from CLK.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 512K × 18 bits - provides 9,437,184 total bits in x18 bus configuration, optimized for 16-bit+ data paths with parity or ECC extension. |
| Max Clock Frequency | 150 MHz - defines maximum sustained burst throughput; supports 150 million synchronous operations per second. |
| Access Time | 3.5 ns - guaranteed read latency from CLK rise to valid Q output under specified load and voltage conditions. |
| Core Supply Voltage | 3.3 V ±5% / +10% - allows operation across industrial temperature range with margin for rail droop and noise. |
| I/O Supply Voltage | 3.3 V or 2.5 V - enables interoperability with mixed-voltage logic families without level shifters. |
| Power-Down Mode | ZZ pin active-high - reduces standby current to ≤10 mA, critical for low-power system sleep states. |
| Burst Control | Linear or interleaved via MODE pin - determines address increment pattern for sequential accesses, matching CPU or DMA burst expectations. |
Pinout & Package
Package: 100-pin TQFP (Thin Quad Flat Package), 14 mm × 14 mm body, 0.5 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1 | Synchronous Address Inputs | Registered on CLK rising edge; used with internal 2-bit counter to generate burst addresses during sequential access. |
| BWa, BWb | Synchronous Byte Write Enables | Active-low controls DQa (bits 0–7) and DQb (bits 8–15); enables partial writes without affecting other bytes. |
| CE1, CE2 | Synchronous Chip Enables | CE1 (active-low) gates ADSP; CE2 (active-high) enables device-supports depth expansion with two independent enables. |
| CLK | Synchronous Clock Input | Rising-edge-triggered master clock for all synchronous registers; defines timing reference for setup/hold requirements. |
| OE | Asynchronous Output Enable | Active-low; enables Q outputs independently of CLK, allowing flexible timing alignment with external controllers. |
| ADSC, ADSP | Synchronous Address Status Controls | ADSC selects/deselects device and latches new address; ADSP initiates read using new address-enables pipelined access. |
| ADV | Synchronous Address Advance | Active-low; advances internal burst counter; HIGH inserts wait state, enabling synchronization with slower masters. |
| MODE | Static Burst Mode Select | LOW = linear burst (0,1,2,3); HIGH/NC = interleaved burst (0,2,1,3)-matches Intel vs. Motorola bus protocols. |
| ZZ | Asynchronous Sleep Control | Active-high forces device into low-power standby; retains data but disables outputs and internal clocks. |
| DQa, DQb | Bi-directional Data I/O | 18-bit data bus split as DQa (D0–D7, D16–D17) and DQb (D8–D15); shared pins reduce package count and PCB routing complexity. |
Key Features
| Feature | Design Value |
|---|---|
| Two-cycle chip deselect | Reduces latency when switching between multiple SRAMs in depth-expanded systems-no wait states required. |
| Internally self-timed write cycle | Eliminates need for external write pulse generation; simplifies controller logic and improves timing margin. |
| JTAG boundary scan (TMS/TDI/TCK/TDO) | Enables IEEE 1149.1-compliant board-level test and debug without requiring additional test fixtures. |
| 5V-tolerant inputs (except I/Os) | Allows direct connection to legacy 5 V logic without level-shifting circuitry-reduces BOM cost and layout area. |
| Clamp diodes to VSS | Provides ESD protection on all pins (±2 kV HBM), enhancing robustness in manufacturing and field environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous burst SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1367A-166AJC | 166 MHz clock, 3.0 ns access time, higher operating current (425 mA max) | Requires tighter timing closure; suitable where 150 MHz margin is insufficient for worst-case skew | Select if system clock domain operates at ≥160 MHz and power budget permits +75 mA increase |
| IS61LV51218AL-150TQLI | Lower power (220 mA typical), no JTAG, no burst mode-pure async interface with CE/OE control | Lacks pipelining and burst; requires external address sequencing logic for sequential access | Choose for cost-sensitive, non-burst applications where deterministic 150 MHz async timing suffices |
Compared with CY7C1367A-150AJC, the -166AJC variant trades higher power for improved timing margin, while the IS61LV51218AL offers lower cost and power at the expense of synchronous burst functionality and JTAG testability.

FAQ
What is the function of the MODE pin on CY7C1367A-150AJC?
The MODE pin selects burst sequence type: LOW configures linear burst (0,1,2,3), while HIGH or NC selects interleaved burst (0,2,1,3). This matches different CPU or DMA controller addressing expectations and must be hardwired during PCB design-no runtime reconfiguration is supported.
Does CY7C1367A-150AJC support JTAG boundary scan?
Yes, CY7C1367A-150AJC in the T/AJ (100-pin TQFP) package includes full IEEE 1149.1 JTAG support via TMS, TDI, TCK, and TDO pins. These pins operate at LVTTL/LVCMOS levels and are not present in the TA package version.
Can CY7C1367A-150AJC operate with a 2.5 V I/O supply while maintaining 3.3 V core voltage?
Yes-the device supports independent VCCQ (I/O supply) at 2.5 V or 3.3 V while VCC (core) remains at 3.3 V ±5%/+10%. This allows seamless interfacing with 2.5 V FPGAs or ASICs without level shifters, provided VCCQ stability meets datasheet ripple specifications.
How does the ZZ pin affect power consumption and data retention?
When ZZ is driven HIGH, the device enters automatic power-down mode, reducing CMOS standby current to ≤10 mA. Data is retained as long as VCC remains within specification; no refresh or external intervention is required during ZZ assertion.
