Infineon Technologies CY7C1061GN30-10BVXI

Overview

CY7C1061GN30-10BVXI from Cypress Semiconductor is a 16-Mbit (1,048,576 × 16) asynchronous CMOS static RAM with 10 ns access time, 2.2–3.6 V operating voltage, dual chip enable (CE1/CE2), and 48-ball VFBGA (8 × 9.5 × 1 mm) package. It supports byte-wide writes via BHE/BLE controls and automatic power-down when deselected, deployed in industrial embedded controllers requiring deterministic low-latency memory access.

For engineers reviewing the CY7C1061GN30-10BVXI datasheet, CY7C1061GN30-10BVXI pinout, CY7C1061GN30-10BVXI application, or CY7C1061GN30-10BVXI equivalent, key selection criteria include tAA ≤ 10 ns, ISB2 = 20 mA (typ), 1.0 V data retention capability, dual CE logic compatibility, and VFBGA thermal resistance (θJA = 31.5 °C/W).

Technical Context

This SRAM implements a fully decoded 20-bit address bus (A0–A19) for 1M-word addressing and a 16-bit bidirectional I/O bus (I/O0–I/O15) partitioned into high/low bytes via BHE and BLE. Read/write operations are controlled by independent OE, WE, CE1, and CE2 signals with TTL-compatible input thresholds and CMOS-level output drive.

Power management relies on dual CE logic: CE1 LOW + CE2 HIGH enables memory, while CE1 HIGH or CE2 LOW forces automatic CMOS standby (ISB2 = 20 mA typ). Data retention operates down to 1.0 V with no clock or refresh required, supporting battery-backed hold modes in power-constrained systems.

FAQ

Is CY7C1061GN30-10BVXI pin-compatible with other densities in the CY7C1061x series?

No. While CY7C1061GN30-10BVXI shares the 48-ball VFBGA (BVXI) footprint with CY7C1061DN30-10BVXI (8-Mbit variant), pin assignments differ for address lines A16–A19 and I/O functions. The 16-Mbit version uses all 20 address bits (A0–A19), whereas lower-density variants leave A16–A19 unconnected or repurposed - direct substitution risks address decoding errors.

Does this SRAM require an external clock or initialization sequence?

No. CY7C1061GN30-10BVXI is a fully asynchronous static RAM with no clock input, no reset pin, and no initialization requirement. It enters operational mode immediately upon stable VCC (2.2–3.6 V) and valid CE/WE/OE control - ideal for systems where boot-time determinism is critical.

Can BHE and BLE be used simultaneously for full 16-bit access?

Yes. When both BHE and BLE are driven LOW, the entire 16-bit I/O bus (I/O0–I/O15) becomes active for simultaneous read or write. This enables full-word transfers matching microcontroller or FPGA native word widths without software byte-splitting overhead.

What is the maximum supported clock frequency for reliable operation?

The device has no clock input, but its AC timing supports reliable operation up to 100 MHz bus frequency. This is validated by ICC = 90 mA (typ) at f = 100 MHz and tAA = 10 ns - meaning address setup/hold and data valid windows are met for synchronous interfaces running at 10 ns cycle time.
