Infineon Technologies CY7C1386KV33-200AXCT

Overview

CY7C1386KV33-200AXCT from Cypress Semiconductor is a 18-Mbit pipelined synchronous SRAM with 512K × 36 organization, supporting 200 MHz bus operation, 3.3 V core (VDD), and dual I/O supply (2.5 V or 3.3 V VDDQ). It features registered inputs/outputs, synchronous self-timed writes, and interleaved/linear burst modes - deployed in high-speed CPU cache subsystems requiring deterministic timing and depth-expansion capability without wait states.

For engineers reviewing the CY7C1386KV33-200AXCT datasheet, CY7C1386KV33-200AXCT pinout, CY7C1386KV33-200AXCT application, or CY7C1386KV33-200AXCT equivalent, key selection criteria include clock-to-output time (3 ns), pipelined enable register behavior for deselect timing, byte-write control granularity (BWA–BWD + BWE + GW), ZZ sleep mode support, and JEDEC-standard 100-pin TQFP packaging compatibility.

Technical Context

This SRAM implements a two-bit synchronous wraparound burst counter, clocked by CLK's rising edge, with address capture triggered by either ADSP (processor strobe) or ADSC (controller strobe). Burst sequencing is user-selectable via MODE pin, enabling linear or interleaved addressing patterns required by x86 or RISC-based cache controllers.

All synchronous inputs-including A[1:0], CE1/CE2/CE3, ADV, BWA–BWD, BWE, GW, and OE-are registered on the CLK rising edge; only OE and ZZ operate asynchronously. Output buffers incorporate a pipelined enable register that delays tristate assertion by one clock cycle during deselect, preserving system-level timing integrity in multi-chip depth-expanded configurations.

FAQ

What is the function of the MODE pin on CY7C1386KV33-200AXCT?

The MODE pin selects burst addressing sequence: logic HIGH configures interleaved burst (e.g., for Pentium-compatible systems), while logic LOW selects linear burst (e.g., for PowerPC or custom controllers). It is sampled synchronously on the rising edge of CLK during the first cycle of a burst access and remains latched for the duration of that burst.

How does the pipelined enable register improve system performance in depth-expanded configurations?

The pipelined enable register delays output buffer tristate assertion by one clock cycle after chip deselect. This prevents bus contention and eliminates the need for wait states when switching between adjacent memory banks - enabling seamless 200 MHz operation across multi-device depth-expanded arrays without external timing compensation.

Can CY7C1386KV33-200AXCT operate with mixed VDDQ voltages across different devices in the same system?

Yes - each device independently accepts either 2.5 V or 3.3 V on VDDQ. This allows heterogeneous interfacing: e.g., one bank connected to a 2.5 V FPGA I/O bank and another to a 3.3 V microcontroller bus, provided VDDQ ground (VSSQ) is properly partitioned and decoupled per supply domain.

Is ZZ sleep mode compatible with continuous clock operation?

Yes - ZZ active-HIGH places the core in low-power retention while allowing CLK to remain running. All registers retain state, and the device resumes full operation within one clock cycle after ZZ returns LOW. This enables dynamic power gating during idle intervals without clock gating complexity or resynchronization overhead.
