Infineon Technologies CY7C1470BV33-167AXC

Overview

CY7C1470BV33 from Cypress Semiconductor is a 72-Mbit (2M × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory subsystems in networking and telecom line cards. It operates at 167 MHz with zero wait states, supports 3.3 V core supply and 3.3 V/2.5 V I/O, and delivers 3.4 ns clock-to-output time. Its fully registered inputs/outputs enable true back-to-back read/write operations in burst or single-access modes.

For engineers reviewing the CY7C1470BV33 datasheet, CY7C1470BV33 pinout, CY7C1470BV33 application, or CY7C1470BV33 equivalent, this device serves as a pin-compatible NoBL SRAM replacement for ZBT™-based systems requiring deterministic latency, byte-write granularity, JTAG boundary scan, and low-power sleep mode (ZZ) in 100-pin TQFP or 165-ball FBGA packages.

Technical Context

The CY7C1470BV33 implements a synchronous, fully registered pipeline where all address, control, and data signals are latched on the rising edge of CLK, with CEN qualifying clock recognition. Its NoBL™ logic eliminates bus latency by enabling consecutive read/write transfers on every clock cycle without interlock cycles.

Burst operation supports linear or interleaved addressing via ADV/LD, while byte write capability (BWa–BWd) enables selective 9-bit writes to DQa–DQd and parity bits DQPa–DQPd. The device integrates IEEE 1149.1 JTAG boundary scan and offers two power management options: asynchronous ZZ Sleep Mode and synchronous Stop Clock via CEN deassertion.

FAQ

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

The ADV/LD pin controls burst address generation: when HIGH (with CEN active), it advances the internal address counter for sequential burst accesses; when LOW, it loads a new starting address from A[17:0]. This enables flexible burst lengths (1–4, 8, or full-page) without external address sequencing logic, critical for packet header parsing and FFT buffering.

Does CY7C1470BV33 support 2.5 V I/O operation?

Yes - the device supports 2.5 V I/O voltage on VDDQ pins while maintaining 3.3 V core (VDD), allowing direct interfacing with 2.5 V FPGAs or ASICs without level shifters. I/O timing parameters (setup/hold, output delay) are specified separately for 2.5 V and 3.3 V VDDQ conditions in the datasheet AC characteristics table.

How does the ZZ Sleep Mode differ from CEN-based clock stopping?

ZZ is an asynchronous, hardware-driven mode that powers down internal clocks and I/O drivers, reducing current to <100 µA; wake-up requires ~100 ns stabilization. CEN deassertion is synchronous and preserves register state, enabling immediate resumption on next clock edge with no latency penalty - ideal for short idle intervals between bursts.

Can CY7C1470BV33 be used as a drop-in replacement for ZBT SRAMs?

Yes - it is pin-compatible and functionally equivalent to ZBT devices (e.g., IDT72T36120), sharing identical pinout, timing protocol, and control signal behavior. However, CY7C1470BV33 adds NoBL™ latency elimination, ZZ sleep, and JTAG - requiring no design change for migration but enabling enhanced power and test capabilities.
