Infineon Technologies CY7C1353G-100AXC

Overview

CY7C1353G-100AXC from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 18) synchronous flow-through SRAM with NoBL™ architecture, designed for zero-wait-state, back-to-back read/write operations in high-bandwidth memory subsystems. It operates at 100 MHz with 8.0 ns clock-to-output delay, supports linear/interleaved burst modes, and features byte-write capability, registered inputs, and 2.5 V/3.3 V I/O power (VDDQ).

For engineers reviewing the CY7C1353G-100AXC datasheet, CY7C1353G-100AXC pinout, CY7C1353G-100AXC application, or CY7C1353G-100AXC equivalent, key selection criteria include synchronous burst timing integrity, ZZ sleep mode behavior, ADV/LD-controlled address loading, and TQFP-100 pin compatibility with ZBT™-class systems.

Technical Context

The CY7C1353G-100AXC implements a fully pipelined, clock-synchronous interface with rising-edge-triggered input registers for all control and address signals. Its NoBL™ logic eliminates bus latency by enabling consecutive read/write transfers on every clock cycle without wait states, supported by internal self-timed write circuitry and synchronous chip enables (CE1–CE3).

Burst operation is controlled by the MODE strap pin and ADV/LD signal, selecting either linear or interleaved 4-word sequences using A[1:0] as counter inputs. Output drivers are synchronously tri-stated during write data capture, and OE remains masked during write cycles to prevent bus contention - ensuring deterministic timing across read-write transitions.

FAQ

What is the correct configuration for the ZZ pin on CY7C1353G-100AXC?

The ZZ pin (Pin 64) must be externally connected to ground per documented errata. Although internally pulled down, floating ZZ causes undefined sleep behavior and potential data corruption. Grounding ensures reliable operation in active mode and prevents unintended entry into sleep state during power-up or noise events.

How does ADV/LD function during burst read sequences?

During burst reads, ADV/LD HIGH increments the internal 2-bit burst counter to generate the next sequential address using A[1:0], while ADV/LD LOW loads a new base address. This dual-mode operation allows seamless transition between burst and random-access modes without external address bus intervention.

Can CY7C1353G-100AXC operate with 2.5 V VDDQ while core VDD remains at 3.3 V?

Yes - VDD (core) and VDDQ (I/O) are independently powered. The device supports 3.3 V core operation with 2.5 V I/O signaling, enabling direct interface to 2.5 V FPGAs or ASICs without level translation, provided VDDQ stability meets ±5% tolerance per datasheet specifications.

Is the MODE pin latched or strap-only at power-up?

The MODE pin is a static strap pin sampled only at power-up reset. Its state (GND = linear, VDD/floating = interleaved) configures the burst counter permanently for that power cycle. It cannot be dynamically changed during operation and requires hardware-level configuration prior to initialization.
