Infineon Technologies CY7C1354C-200AXIT

Overview

CY7C1354C-200AXIT from Cypress Semiconductor is a 9-Mbit (256K × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory subsystems in networking and telecom line cards. It operates at 200 MHz with zero wait states, supports 3.3 V core supply and 2.5/3.3 V I/O, and delivers 3.2 ns clock-to-output timing. Its fully registered interface enables true back-to-back read/write operations in burst or single-access modes.

For engineers reviewing the CY7C1354C-200AXIT datasheet, CY7C1354C-200AXIT pinout, CY7C1354C-200AXIT application, or CY7C1354C-200AXIT equivalent, key selection criteria include burst order configuration (linear/interleaved via MODE pin), byte-write granularity (BWa–BWd), synchronous self-timed write control, JTAG boundary-scan support, and TQFP-100 package compatibility with ZBT-family designs.

Technical Context

The CY7C1354C-200AXIT implements a fully synchronous, pipelined memory architecture where all address, control, and data inputs are registered on the rising edge of CLK, and all outputs pass through output registers synchronized to the same edge. Its NoBL™ logic eliminates bus latency by enabling consecutive read/write cycles without wait states.

It integrates internal burst logic with selectable linear or interleaved addressing (via MODE strap), synchronous self-timed write circuitry, and IEEE 1149.1-compliant boundary-scan testability. The device uses three chip enables (CE1 active-low, CE2 active-high, CE3 active-low) for flexible bank decoding and supports ZZ sleep mode for low-power standby.

FAQ

What is the function of the MODE pin on CY7C1354C-200AXIT?

The MODE pin is a static strap input that selects burst addressing order: logic HIGH configures interleaved burst mode, while logic LOW selects linear burst mode. It must be driven to a defined voltage level during power-up and held stable thereafter, as it is sampled only at initialization and not re-evaluated during operation.

Can CY7C1354C-200AXIT operate with 2.5 V I/O while using 3.3 V core supply?

Yes - the device supports independent VDD (3.3 V) and VDDQ (2.5 V or 3.3 V) supplies. When VDDQ = 2.5 V, all I/O pins (DQa–DQd, DQPa–DQPd, BWa–BWd, etc.) operate at 2.5 V logic levels, enabling direct connection to 2.5 V FPGAs or ASICs without level-shifting circuitry.

How does the ZZ (sleep) mode affect data retention and wake-up time?

In ZZ mode (pin driven LOW), the device enters deep sleep with typical standby current <40 µA while retaining all stored data. Wake-up is synchronous: the first valid CLK edge after ZZ deassertion initiates internal recovery, and normal access resumes after one clock cycle - no additional latency or initialization sequence is required.

Is CY7C1354C-200AXIT pin-compatible with ZBT SRAMs?

Yes - the CY7C1354C-200AXIT is explicitly designed as pin-compatible and functionally equivalent to industry-standard ZBT SRAMs (e.g., IDT 72V2115). This includes identical pin assignments for CLK, CEN, CE1–CE3, WE, ADV/LD, BWa–BWd, DQa–DQd, and DQPa–DQPd in the 100-pin TQFP package.
