Cypress Semiconductor Corp CY7C1472BV33-200BZXC

Overview

CY7C1472BV33-200BZXC from Cypress Semiconductor is a 3.3 V, 4M × 18 (72-Mbit) synchronous pipelined SRAM with NoBL™ architecture, supporting 200 MHz zero-wait-state bus operation, 3.0 ns clock-to-output time, and byte-write capability via BWa–BWb inputs. It serves as high-throughput data buffer in network packet processors requiring back-to-back read/write transitions.

For engineers reviewing the CY7C1472BV33-200BZXC datasheet, CY7C1472BV33-200BZXC pinout, CY7C1472BV33-200BZXC application, or CY7C1472BV33-200BZXC equivalent, key selection criteria include synchronous self-timed write timing, JEDEC-standard 100-pin TQFP package compatibility, burst mode support (linear/interleaved), and IEEE 1149.1 JTAG boundary scan integration.

Technical Context

The device implements fully registered synchronous I/O: all address, control, and data signals pass through input registers on CLK rising edge; outputs are latched on the same edge. Its NoBL™ logic eliminates bus latency by enabling true back-to-back read/write operations without wait states.

Write operations are controlled by WE and two byte-write selects (BWa, BWb), each governing one 18-bit data group (DQa/DQPa and DQb/DQPb). The internal burst counter advances on ADV/LD HIGH, while OE remains asynchronous for output tri-state control independent of clock phase.

FAQ

What is the function of the ADV/LD pin in burst operations?

The ADV/LD pin controls the internal address counter: when HIGH and CEN is active, it increments the burst address automatically; when LOW, it loads a new starting address from A[17:0]. This dual-mode operation enables seamless transition between sequential burst reads and random-access reloads without external address generation logic.

How does the ZZ pin affect data retention and power consumption?

When ZZ is asserted LOW, the device enters deep sleep mode with standby current ≤120 mA while maintaining full data retention in the SRAM array. Power is restored within one clock cycle upon ZZ deassertion, with no initialization delay - critical for low-duty-cycle radar or burst-traffic applications.

Can CY7C1472BV33-200BZXC operate with 2.5 V I/O voltage while maintaining 3.3 V core supply?

Yes - VDDQ supports 2.5 V ±0.2 V operation independent of VDD (3.3 V ±0.3 V), allowing direct interfacing with 2.5 V FPGAs or ASICs without level shifters. All timing parameters in the datasheet are validated for both 3.3 V and 2.5 V VDDQ conditions.

Is the 100-pin TQFP package of CY7C1472BV33-200BZXC pin-compatible with CY7C1470BV33 variants?

No - although both use 100-pin TQFP, CY7C1470BV33 (2M × 36) has four byte-write inputs (BWa–BWd) and different DQ/DQP pin assignments, while CY7C1472BV33 (4M × 18) uses only BWa/BWb and allocates pins for its 18-bit-wide data path. Pin mapping differs in DQ group routing and BW signal count.
