Infineon Technologies CY7C1462KVE25-167BZI

Overview

CY7C1462KVE25-167BZI from Cypress Semiconductor is a 36-Mbit synchronous pipelined SRAM with NoBL™ architecture and integrated ECC, configured as 2M × 18 or 1M × 36. It operates at 167 MHz with 3.4 ns max access time, 2.5 V core/I/O supply, and supports zero-wait-state burst reads/writes in networking packet buffers and telecom line cards.

For engineers reviewing the CY7C1462KVE25-167BZI datasheet, CY7C1462KVE25-167BZI pinout, CY7C1462KVE25-167BZI application, or CY7C1462KVE25-167BZI equivalent, key selection criteria include ECC-enabled soft-error resilience, synchronous self-timed write timing, byte-write granularity (BWa–BWb), JTAG boundary-scan testability, and compatibility with ZBT™-based memory subsystems.

Technical Context

This SRAM implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK; all outputs pass through output registers synchronized to CLK. The internal burst logic supports linear or interleaved addressing, and ADV/LD controls counter advancement or new address loading.

ECC encoding/decoding is performed on-chip for all 36-bit data words (including parity bits DQPa–DQPd), correcting single-bit errors and detecting double-bit errors. Sleep mode (ZZ) is controlled asynchronously, while clock enable (CEN) provides cycle extension without deselection.

FAQ

What is the function of the ADV/LD pin in CY7C1462KVE25-167BZI?

The ADV/LD pin controls the internal burst address counter: when HIGH and CEN is active, it advances the counter for sequential burst accesses; when LOW, it loads a new starting address from A[18:0]. This dual-mode operation enables both streaming transfers and random-access initiation without external address sequencing logic.

Does CY7C1462KVE25-167BZI support interleaved burst mode?

Yes - the device supports both linear and interleaved burst orders via MODE pin configuration. Interleaved mode maps to standard cache-line addressing used in PowerPC and older x86 processors, enabling drop-in replacement in legacy ZBT™-based systems without firmware changes.

How does the on-chip ECC operate with the DQP pins?

DQPa–DQPb carry parity bits generated by the on-chip ECC encoder during writes; during reads, the same pins deliver decoded parity for SEC-DED correction. The ECC engine processes full 36-bit words (18 data + 2 parity per segment), requiring no external syndrome calculation or correction logic.

Can CY7C1462KVE25-167BZI be used in place of a ZBT™ SRAM?

Yes - it is pin-compatible and functionally equivalent to ZBT™ devices (e.g., IDT 72V2113), supporting identical timing protocols, burst orders, and control signal behavior. No PCB or firmware modifications are needed for migration, provided 2.5 V supply and ECC handling are accommodated.
