Infineon Technologies CY7C1462KV25-200AXCT

Overview

CY7C1462KV25-200AXCT from Cypress Semiconductor is a 36-Mbit synchronous pipelined SRAM with NoBL™ architecture and on-chip ECC, configured as 2M × 18 (18-bit data bus), operating at 200 MHz with 3.2 ns clock-to-output delay, 2.5 V core/I/O supply, and JEDEC-standard 100-pin TQFP package. It enables zero-wait-state back-to-back read/write in high-throughput packet buffering applications.

For engineers reviewing the CY7C1462KV25-200AXCT datasheet, CY7C1462KV25-200AXCT pinout, CY7C1462KV25-200AXCT application, or CY7C1462KV25-200AXCT equivalent, key selection criteria include burst mode support (linear/interleaved), byte-write capability (BWa–BWb), synchronous self-timed writes, JTAG boundary scan compliance, and ECC-enabled soft error mitigation for telecom infrastructure 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 are driven through output registers synchronized to CLK. The internal NoBL™ logic eliminates bus latency by enabling true consecutive read/write cycles without wait states.

It integrates on-chip ECC encoding/decoding for single-bit error correction and double-bit error detection, reducing soft error rate (SER) in radiation-sensitive environments. Burst addressing supports both linear and interleaved orders, controlled by MODE and ADV/LD, with synchronous chip enables (CE1, CE2, CE3) and asynchronous OE for flexible bank selection and output control.

FAQ

What is the function of the MODE pin on CY7C1462KV25-200AXCT?

The MODE pin selects burst addressing order: logic HIGH configures linear burst (A0–A18 increment sequentially), LOW selects interleaved burst (bit-reversed address sequence). This setting is sampled at power-up or reset and remains static during operation - it does not support dynamic reconfiguration.

Does CY7C1462KV25-200AXCT support independent parity write control?

Yes. Parity bits on DQPa–DQPb are written concurrently with data on DQa–DQb under identical byte-write enable conditions: BWa gates DQa/DQPa, BWb gates DQb/DQPb. There is no separate parity write control - parity is always updated with its associated 9-bit data subword.

How does the ZZ (sleep) mode interact with ECC functionality?

In ZZ mode, the SRAM enters ultra-low-power state (<5 mA ICC) while preserving all stored data and ECC syndrome bits. Upon exit, ECC remains fully operational immediately - no reinitialization or syndrome recalculation is required. The memory array and ECC circuitry retain state transparently across sleep/wake cycles.

Can CE2 be left unconnected in a single-SRAM system?

No. CE2 is an active-HIGH synchronous enable and must be held at a valid logic level. Leaving it floating risks metastability and unintended device deselection. For single-device use, tie CE2 HIGH (to VDD) and control selection using CE1/CE3. The datasheet specifies VIH ≥ 2.0 V for reliable operation.
