Infineon Technologies CY7C1470BV33-200BZC

Overview

CY7C1470BV33 from Cypress Semiconductor is a 72-Mbit (2M × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory buffering in network packet processors and telecom line cards. It operates at 200 MHz with zero wait states, supports 3.3 V core supply and 3.3 V/2.5 V I/O, and delivers 3.0 ns clock-to-output time.

For engineers reviewing the CY7C1470BV33 datasheet, CY7C1470BV33 pinout, CY7C1470BV33 application, or CY7C1470BV33 equivalent, key selection criteria include burst read/write capability, byte-write select granularity (BWa–BWd), synchronous self-timed write control, and JEDEC-standard 100-pin TQFP packaging for board-level timing integrity.

Technical Context

The CY7C1470BV33 implements fully registered synchronous interfaces: all address, control, and data inputs are latched 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 back-to-back read/write operations without wait states.

It supports linear or interleaved burst orders, includes three synchronous chip enables (CE1 low, CE2 high, CE3 low) for bank selection, and uses internal self-timed output buffer control-removing dependency on asynchronous OE for output tri-state management during writes.

FAQ

What is the function of the ADV/LD pin in CY7C1470BV33?

The ADV/LD pin controls the internal address counter: when HIGH and CEN is active, it advances the burst address counter; when LOW, it loads a new starting address from A[17:0]. After device deselection, ADV/LD must be driven LOW to accept a new address - ensuring deterministic burst initialization in multi-cycle memory transactions.

Does CY7C1470BV33 support both linear and interleaved burst modes?

Yes - burst order is selected via the MODE pin: MODE = LOW configures linear burst (sequential increment), MODE = HIGH selects interleaved burst (bit-swapped addressing). This dual-mode capability allows compatibility with both PowerPC and x86-based memory controllers without external address translation logic.

How does the ZZ Sleep Mode affect data retention and power draw?

In ZZ mode, the CY7C1470BV33 reduces CMOS standby current to ≤120 mA while maintaining full data retention across the industrial temperature range (–40°C to +85°C). The device exits ZZ mode synchronously on the next valid CLK edge after ZZ is deasserted, with no additional latency beyond standard access timing.

Can CY7C1470BV33 operate with 2.5 V I/O while using 3.3 V core supply?

Yes - VDDQ (I/O supply) accepts 2.5 V ±0.2 V independently of VDD (3.3 V ±0.3 V), allowing direct interfacing with 2.5 V FPGAs or ASICs. I/O voltage level is internally detected; no external configuration is needed, and AC timing parameters remain valid per datasheet specifications at 2.5 V VDDQ.
