Product details
Overview
CY7C1380D-167AXI from Infineon Technologies is a 18-Mbit synchronous SRAM organized as 512K × 36, operating at 167 MHz with 3.3 V core supply, 2.5 V I/O supply, and 5.5 ns access time. It serves as high-speed buffer memory in network packet processors and telecom line cards requiring burst-mode data throughput.
For engineers reviewing the CY7C1380D-167AXI datasheet, CY7C1380D-167AXI pinout, CY7C1380D-167AXI application, or CY7C1380D-167AXI equivalent, key selection criteria include synchronous burst interface timing, dual-cycle write enable support, JTAG boundary-scan compliance, and industrial temperature range operation.
Technical Context
This SRAM implements a pipelined synchronous architecture with programmable burst length (1, 2, 4, 8, or full-page) and supports both interleaved and linear burst ordering. It features separate byte-write enables for all four 9-bit nibbles and includes an on-chip termination resistor control register.
The device uses a 100-pin TQFP package with 3.3 V core logic and 2.5 V I/O voltage domains, supporting SSTL_2-compatible inputs and outputs. It integrates JTAG IEEE 1149.1 boundary-scan for board-level testability and includes power-down mode with automatic self-refresh disable.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1380D-167BZI | Same die, 100-pin BGA (11×11 mm) instead of TQFP; no exposed thermal pad | Better high-frequency signal integrity but requires BGA rework capability and tighter layout spacing | Select for space-constrained designs where thermal pad soldering is feasible and BGA assembly is available |
| IS61WV102436BLL-167TQLI | 18-Mbit 167 MHz SRAM with 3.3 V only supply (no 2.5 V I/O); 5.8 ns access time | Lacks dual-voltage I/O and JTAG, limiting use in mixed-voltage FPGA systems and production test coverage | Select when cost sensitivity outweighs need for JTAG testability and 2.5 V interface compatibility |
Compared with CY7C1380D-167BZI, the AXI variant offers easier rework and thermal pad visibility; versus IS61WV102436BLL-167TQLI, it provides superior testability and mixed-voltage flexibility at higher PCB routing overhead.

FAQ
What is the minimum supported burst length for CY7C1380D-167AXI?
The device supports burst lengths of 1, 2, 4, 8, or full-page (512 words). Minimum burst length is 1 word (36 bits), configurable via mode register settings during initialization. This allows single-word random access for control register updates while retaining full burst capability for data streaming.
Does CY7C1380D-167AXI require external termination resistors?
No. The device includes programmable on-chip termination (OCT) for all data and address I/Os, configurable as 50 Ω pull-up or pull-down via dedicated mode register bits. External resistors are optional only for non-standard impedance targets or legacy system compatibility.
Can CY7C1380D-167AXI operate with only a 3.3 V supply?
No. It requires two independent supplies: 3.3 V ±0.3 V for core logic and 2.5 V ±0.2 V for I/O. Applying 3.3 V to the VDDQ pins exceeds absolute maximum ratings and may cause permanent damage or signal integrity failure on SSTL_2 interfaces.
Is JTAG boundary-scan functional during normal memory operation?
Yes. JTAG remains fully accessible and operational regardless of memory state-active read/write, idle, or power-down. Test access does not interfere with ongoing data transactions, enabling concurrent system debug and functional operation.
