Infineon Technologies CY7C1460KV25-167BZCT

Overview

CY7C1460KV25-167BZCT from Cypress Semiconductor is a 36-Mbit synchronous pipelined SRAM with NoBL™ architecture and on-chip ECC, configured as 1M × 36 or 2M × 18. It operates at 167 MHz with 3.4 ns max access time, 2.5 V core/I/O supply, and supports zero-wait-state back-to-back read/write in high-throughput networking and packet buffering applications.

For engineers reviewing the CY7C1460KV25-167BZCT datasheet, CY7C1460KV25-167BZCT pinout, CY7C1460KV25-167BZCT application, or CY7C1460KV25-167BZCT equivalent, key selection criteria include burst mode support (linear/interleaved), byte-write capability with BWa–BWd, synchronous self-timed writes, JTAG boundary scan compliance, and ZZ sleep mode for power-sensitive embedded systems.

Technical Context

This SRAM implements fully registered pipelined operation: all address, control, and data inputs pass through input registers on CLK rising edge; all outputs are clocked through output registers on the same edge. The NoBL™ logic eliminates bus latency by enabling true back-to-back read/write cycles without wait states.

It integrates on-chip ECC encoding/decoding to detect and correct single-bit errors, reducing soft error rate (SER) in radiation-prone environments. Burst addressing supports both linear and interleaved orders, and internal self-timed output buffer control removes dependency on asynchronous OE timing.

FAQ

What is the function of the MODE pin on CY7C1460KV25-167BZCT?

The MODE pin selects burst addressing order: logic HIGH configures linear burst, LOW selects interleaved burst. This setting is sampled synchronously on the rising edge of CLK when CEN is active, and must be stable before burst initiation to ensure correct address sequencing during burst reads/writes.

Does CY7C1460KV25-167BZCT require external termination resistors on its DQ bus?

No external termination is required. The device features internally matched output drivers optimized for 50 Ω transmission lines. AC switching characteristics in the datasheet assume 50 Ω load with 2.5 V supply, and output impedance is calibrated to maintain signal integrity without added components.

How does the ZZ sleep mode interact with data retention and clock gating?

In ZZ mode, the device enters ultra-low-power state (<50 µA ICC) while retaining all stored data. CLK is ignored, and CEN has no effect. All I/O pins enter high-impedance state except for ZZ, which must remain asserted LOW. Exit requires deasserting ZZ followed by two valid CLK cycles before normal operation resumes.

Can CY7C1460KV25-167BZCT operate in 2M × 18 mode without hardware reconfiguration?

Yes - the 2M × 18 configuration is selected automatically based on address mapping: A18–A0 are used as row/column addresses, and the internal decoder interprets the access pattern. No strap pins or register writes are needed; mode is transparent and determined solely by external address generation logic.
