Infineon Technologies CY7C1061GN18-15ZSXIT

Overview

CY7C1061GN18-15ZSXIT from Cypress Semiconductor is a 16-Mbit (1M × 16) asynchronous CMOS static RAM with dual chip enable (CE1/CE2), 15 ns access time, 2.2–3.6 V operating voltage, and 20 µA typical CMOS standby current (ISB2). It supports byte-wide write control via BHE/BLE and operates in industrial temperature range (–40 °C to +85 °C) for embedded memory buffering in FPGA co-processor systems.

For engineers reviewing the CY7C1061GN18-15ZSXIT datasheet, CY7C1061GN18-15ZSXIT pinout, CY7C1061GN18-15ZSXIT application, or CY7C1061GN18-15ZSXIT equivalent, key selection criteria include tAA = 15 ns timing at 3.3 V, dual CE architecture for hierarchical memory mapping, low-voltage data retention (1.0 V), TTL-compatible I/O levels, and VFBGA-48 package compatibility with high-density PCB layouts.

Technical Context

This SRAM implements a fully decoded 1M-word × 16-bit array with independent byte write enables (BHE/BLE) enabling selective 8-bit writes without read-modify-write cycles. Its dual CE logic (CE1 LOW + CE2 HIGH = active) allows seamless integration into multi-chip memory banks with address decoding granularity.

It features automatic power-down when deselected, delivering ISB2 = 20 µA (typ) at VCC = 3.3 V, and supports 1.0 V data retention with tCDR = 0 ns - meaning retention mode engages immediately upon CE deassertion. All I/Os are TTL-compatible with VIH/VIL thresholds scaled across 2.2–3.6 V supply ranges.

FAQ

What is the maximum operating frequency supported by CY7C1061GN18-15ZSXIT?

The device does not operate on a clock; it is an asynchronous SRAM. Its 15 ns access time (tAA) corresponds to a maximum effective interface rate of approximately 66.7 MHz when interfaced with a microcontroller or FPGA using standard address-valid-to-data-valid timing. No internal clock circuitry is present.

Does CY7C1061GN18-15ZSXIT require external pull-up resistors on CE1, CE2, or BHE/ BLE?

No external pull-ups are required. All control inputs (CE1, CE2, WE, OE, BHE, BLE) have internally biased TTL-compatible thresholds and do not rely on external biasing. However, floating inputs must be avoided per design best practice - tie unused control lines to defined logic levels.

Can CY7C1061GN18-15ZSXIT operate at 1.8 V?

No. The specified minimum VCC is 2.2 V per the Industrial operating range. While some units may function at 1.8 V, it violates the datasheet's absolute maximum ratings and invalidates timing guarantees, data retention, and ISB2 current specs. Use only within 2.2–3.6 V.

Is the 48-ball VFBGA package (BVJXI) compatible with standard reflow profiles?

Yes. The BVJXI package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles with peak temperatures up to 260 °C. Board layout must follow Cypress's recommended pad stack and stencil aperture guidelines for reliable solder joint formation.
